11 PRE-DRAFT O&M PLAN VA SALT LAKE CITY HEALTH CARE SYSTEM SALT LAKE CITY, UTAH MARCH INTRODUCTION Under Contract No. W912DQ-15-D-3010 with the U.S. Army Corps of Engineers Kansas City District (USACE), CTI and Associates, Inc. (CTI) has prepared the following Operation and Maintenance (O&M) Plan for the routine operations of the 040-H vapor mitigation system associated with the Accelerated Operable Unit (AOU) 1 Time Critical Removal Action and Mitigation System Installation for the 700 South 1600 East PCE Plume Superfund Site, VA Salt Lake City Health Care System Salt Lake City, Utah. This Operation and Maintenance (O&M) Plan addresses the scope of work requirement for the O&M of the vapor mitigation system in accordance with the Performance Work Statement (PWS) issued August 3, Site Location The Site, which consists of Building 040-H, is located in Salt Lake City, Utah (See Figure 1). The 040-H location is a privately owned residence and is situated within a westward sloping residential lot of the East Side Springs (ESS) area with visible seeps and springs located in the eastern and northern portions of the lot. The eastern portion of the lowest level of the house is below grade, and the western portion of the lowest level is partially below grade, with a partially below grade living space in the northwest corner of the lowest level and a walkout garage at grade in the southwest corner of the lowest level. The resident reported that a clay pipe traverses from east to west within the foundation to convey spring water and groundwater from the wetter eastern portion of the lot to the western portion of the lot where the clay pipe discharges to a small pond. Residence 040-H is located within a PCE plume that is thought to be the western extent of the 700 South 1600 East PCE Plume. Residence 040-H was identified by VA as having the potential of being adversely affected by the PCE plume through the subsurface to indoor air VI pathway (Figure 1). Seeps, springs, and groundwater in this area with detections of PCE and TCE are most likely associated with the 700 South 1600 East PCE Plume. The plume is located within the Salt Lake City alluvial basin near the Wasatch Mountain front. The Salt Lake City alluvial basin is bounded to east by the Wasatch Fault and a seismically independent segment of the Wasatch fault called East Bench Segment Fault. A drop in surface elevation due to the Wasatch fault scarp has resulted in the development of seeps and springs from groundwater daylighting between 800 South and Michigan Avenue (approximately 1300 South) and between 1000 East and 1300 East. This area is within the ESS area. The focus area for vapor intrusion (VI) lies CONTRACT NO. W912DQ-15-D

12 PRE-DRAFT O&M PLAN VA SALT LAKE CITY HEALTH CARE SYSTEM SALT LAKE CITY, UTAH MARCH 2017 within the ESS. Residence 040-H is located in the central portion of the ESS area, south of 900 South and east of 1200 East (Figure 1). Current land use near residence 040-H includes single family residential properties with several schools, churches, and small businesses located along the major streets. The few commercial operations near the residence include an auto repair shop/gasoline station, convenience store, and coffee shop located near the intersections of 800 South and 900 South with 1300 East. CTI designed a vapor intrusion mitigation system (VIMS) that consists of an Amaircare whole house air purifier installed on the suction side of the house furnace. The unit is equipped with 36 pounds of active carbon using installed optional carbon filters available from the manufacturer which are required for use as VIMS. This equipment installation was completed on November 18, 2016 in accordance with the approved work plan and design change notice 1 (DCN-01). DCN-01 added a vacuum induced damper to the suction of the furnace to allow for additional untreated air to be drawn into the furnace if for some reason the air purifier supply is insufficient. The damper closes automatically when the ducting is not under a vacuum to allow for the air purifier to circulate treated air thought out the house supply air ducting. 1.2 Purpose The installed VIMS needs to be operated and maintained in accordance with this document to continue to provide adequate capture of contaminants that appear to intrude into the residence. The purpose of this document is to present specific details on the proper operation, maintenance and monitoring of the installed VIMS. Proper operation of the VIMS is necessary to maintain performance of the system to capture potential indoor air contaminants that may enter the basement from the 700 South 1600 East PCE plume in the vicinity of residence 040-H. A summary of work includes the following: Routine Inspections: o Visually inspect equipment for any damage/leaks or other problems; o Record the electrical meter reading for the air purifier supply; o Measure air flow at the air purifier intake, discharge to furnace, and furnace discharge; and o Measure total volatile organic compounds (VOCs) with ppbrae Photoionization Detector with 10.6 ev bulb (PID). CONTRACT NO. W912DQ-15-D

13 PRE-DRAFT O&M PLAN VA SALT LAKE CITY HEALTH CARE SYSTEM SALT LAKE CITY, UTAH MARCH 2017 Maintenance for the Amaircare Air Purifier: o Change pre-filters -when particle buildup on the filter is observed (typically every 3-4 months based on initial year quarterly inspections); and o Change HEPA filters and carbon filters; (Every 12 months based on manufacturers recommendations for the optional carbon canisters installed). Indoor Air Sampling: o One 24-hour TO15 select ion method (SIM) sample for target analytes will be collected from each floor of residence 040-H, a duplicate sample will be collected during each sample event from a random location. Samples events will occur during each quarter during year one and semiannual for years 2 and 3 to monitor the performance of the vapor mitigation system during operations; o All analytical work shall be performed by a National Environmental Laboratory Accreditation Program (NELAP) accredited laboratory in accordance with the applicable portions of the AOU1 Quality Assurance Project Plan (QAPP) to the extent practical; and o The results will be provided to USACE PM and VA Program Manager. CONTRACT NO. W912DQ-15-D

14 PRE-DRAFT O&M PLAN VA SALT LAKE CITY HEALTH CARE SYSTEM SALT LAKE CITY, UTAH MARCH OPERATIONS AND MAINTENANCE The Amaircare installed for vapor mitigation operates continuously by running three fans that draw cold return air from the plenum closet through pre-filters, high-efficiency particulate air (HEPA) filters, and high capacity carbon filters. The treated air is discharged to the suction of the house furnace suction which directs the treated air throughout the residence s supply ducts. The furnace/ac will continue to operate as normal during heating and cooling months and the Amaircare will act as an additional filter to the furnace. If for some reason the furnace controls draw more air than is fed to the intake by the air purifier forming a suction, additional make up air will be drawn automatically through the static pressure damper. This condition could occur if the pre-filters begin to foul over time or the furnace variable speed fan draws more air than the Amaircare can supply. 2.1 Inspections with Routine Maintenance The system will be inspected quarterly throughout the initial year of operation. The inspections will determine the actual pre-filter change out requirements. It has been assumed to be quarterly at this time. The O&M Inspection Checklist (Form 1) will be completed during every inspection event. Sequence of events: 1.

You will quickly realize that you have purchased a very effective air cleaning system. It incorporates state of the art HEPA (High Efficiency Particulate Air) technology. Your Amaircare HEPA system comes with a limited warranty. With proper attention to its care and maintenance, you will receive optimum performance. If your indoor air has abnormally high concentrations of particulates, the life span of the filter media may be shortened. Excessive particulates in the air will reduce the expected life of the HEPA filter. Under normal conditions the HEPA filter will last from two to five years. The optional activated carbon canister has a finite limit as to the amount of odor or other gaseous volatile organic compounds (V.O.C. s) that it can adsorb. The higher the concentrations, the shorter the expected life. Higher humidity may shorten the life of the carbon canister. Under normal conditions, the carbon canister should last up to 12 months. Initially, the HEPA filter s particulate removal efficiency improves with use. However, the air flow through the HEPA filter media will decrease, as dust builds up on the filter, thus lowering its ability to circulate and clean as much air as when it was new. If the air flow through your unit is noticeably reduced, you can inspect the pre-filter and HEPA filter to see if they should be replaced. Replacement (or washing if foam) of the prefilter every 3 months will help extend the life of the HEPA filter. Please contact your local Amaircare dealer regarding replacement of filter media, warranty information or if you have any questions or concerns about the performance of your HEPA system. NOTE: This filtration system is an ADDITIONAL filter, and does NOT replace the existing air handler/furnace system filter. 2

45 General Information Media Filters Media filters strain particulates from the air. The filter media needs to have tiny holes to allow air to pass through, but not particulates. Filter types vary for all sorts of purposes. The most effective and proven filter media is HEPA. HEPA filter media is 99.97% efficient at capturing particles which are 0.3 micron in size or larger. Carbon Filters Carbon media is used to capture chemicals and odors, also referred to as V.O.C. s. Chemicals and odors cannot be captured with media type filters. Activated carbon collects chemicals and odors in a process called adsorption. If air passes through the carbon filter before particulates are removed, the surface of the carbon quickly gets covered with particulates, rendering it ineffective at capturing chemicals and odors. If particulates are removed from the air with a HEPA filter, virtually the entire surface area of the carbon can be used to capture chemicals and odors. This increases the efficiency and filter life of the carbon filter. Separate HEPA and Carbon Filters HEPA and carbon filters have different life spans. It is important for a filtration system to keep the filter components independent from each other, so that the filter that is dirty/saturated can be changed. This is more economical than a system where you need to throw out two or three filters when only one needs changing. The HEPA System s 3 Stage Filtration Process The 3 stage filtration process is used to create a very effective filtration system. Each filter is independent and can be changed individually. Stage 1: Pre-filter - The inexpensive pre-filter (foam or carbon) removes larger particulates from the air, thus prolonging the life of the HEPA filter. Stage 2: HEPA - The HEPA filter removes 99.97% of particulates 0.3 micron and larger. The cleaned air then passes through the third stage filter. Stage 3: Carbon - The carbon filter is about 1/2 an inch thick to give it plenty of surface area for removing chemicals and odors from the air. This filter may be replaced by an optional heavy duty granular carbon canister available for maximum removal of chemicals and odors. The clean air is then reintroduced into the air you breathe.

50 Dealer Installation Instructions Forced air handler/furnace systems: The HEPA system should be installed as a bypass system, with part of the return ducted into the HEPA system. The filtered air is then rerouted back into the return air, and continues through the system to be heated/cooled. Typical Return to Return Application For homes with upflow forced air handler/furnace systems.(air handler/furnace is shown in a typical basement. See A Figure 6.) Distance between A and B should be 6' to 16' for best results B 8 Typical Return to Return Application For homes with horizontal forced air handler/furnace systems. (Air handler/furnace is shown in an typical attic. See figure 7.) Air Handler/ Furnace Air Handler/Furnace Filter Distance between A and B should be 6' to 16' for best results HEPA System Figure 11. Figure 12. NOTE: This filtration system is an ADDITIONAL filter, and does NOT replace the existing air handler/furnace system filter. Preparation: Here are some things to consider as you decide where to install the HEPA system. Location: Make sure there is room to open the HEPA filter access panel for filter changes/inspections. Keep the HEPA system in a location where you can still access the air handler/furnace filter. Keep the HEPA system away from possible water damage. Vibration pads will reduce vibration for installations where the unit is placed on the floor. Install HEPA System on floor or suspended platform. If the unit is suspended, screws must not penetrate through the cabinet. Make sure that you have the proper chains/straps/joists and equipment to keep unit secure. Intake (Marked as Air In on unit): Intake ducts should be installed upstream of any humidifiers and be installed on the main return. Intake duct should be installed at least 6 ft. away from the outflow duct on the main return. Outflow (Marked as Clean Air Out on unit): Outflow duct should be installed as close to the air handler/furnace inlet as possible but not directly into the return air elbow of the main return. If the unit is being installed independently of any other system, room diffusers are recommended to help distribute airflow evenly in the occupied space. Ducting: If HEPA system is installed where inlet and outflow collars face down, metal elbows must be connected to both inlet and outflow collars. Each connection must be sealed with aluminum tape or mastic, including all take offs. Installed duct runs should be as straight as possible (if the duct runs are too long, reduced CFM may result). If duct is exposed to unconditioned air, externally insulated flex duct is highly recommended. Externally insulated flex duct can also be used for noise reduction purposes. For best indoor air quality, do not use ductboard or fiberglass inside of ducts. Electricity: The unit must be plugged into a grounded 120V, 60Hz outlet.

51 Dealer Installation Instructions Forced air handler/furnace system with an HRV/ERV This application provides filtration of all Outdoor Air (OA) that is brought into the home through the HRV/ERV, thus reducing the introduction of dust, pollen and mold from the outdoor air. For systems that have HRV/ERV units installed, we recommend ducting the fresh air outflow from the HRV/ERV into the HEPA system. If the HRV/ERV CFM (cubic feet per minute) rating is lower than that of the HEPA system, an additional return needs to be installed into the HEPA system (See figure 8.) The outflow air from the HEPA system then needs to be installed into the main return of the air handler/furnace system. Ensure that you follow the proper installation instructions as outlined in the HRV/ERV Installation manual(s). Preparation: Here are some things to consider as you decide where to install the HEPA system with an HRV/ERV. Location: Make sure there is room to open the HEPA filter access panel for filter changes/inspections. Keep the HEPA system in a location where you can still access the air handler/furnace filter. Keep the HEPA system away from possible water damage Vibration pads will reduce vibration for installations where the unit is placed on the floor. Install HEPA System on floor or suspended platform. If the unit is suspended, screws must not penetrate through the cabinet. Make sure that you have the proper chains/straps/joists and equipment to keep unit secure. Intake (Marked as Air In on unit): Most HRV/ERV systems will not move as much air as the HEPA system. For these systems, install an additional return from another treated air source into the HEPA system. If using an additional return duct, it should be installed upstream of any humidifiers. The fresh air outflow of the HRV/ERV should be "Y" connected to the additional return duct then connected to the inlet of the HEPA system. The additional return duct (if any) should be installed at least 6 ft. away from the outflow duct on the main return. Duct both the HRV/ERV and the additional return into the intake of the HEPA system. Outflow (Marked as Clean Air Out on unit): Outflow duct should be installed as close to the air handler/furnace inlet as possible but not directly into the return air elbow of the main return. Ducting: If HEPA system is installed where inlet and outflow collars face down, metal elbows must be connected to both inlet and outflow collars. Each connection must be sealed with aluminum tape or mastic, including all take offs. Installed duct runs should be as straight as possible (if the duct runs are too long, reduced CFM may result). If duct is exposed to unconditioned air, externally insulated flex duct is highly recommended. Externally insulated flex duct can also be used for noise reduction purposes.

52 Dealer Installation Instructions Independent Operation: The HEPA systems can be used independently of any other equipment! The intake and outflow of the filtration system can be ducted into the same room to create a cleaner environment almost anywhere. The intake or outflow can also be ducted elsewhere. The intake and outflow should be installed on opposite sides of the room; however, this varies according to your specific needs. Preparation: Here are some things to consider as you decide where to install the HEPA system independently of other systems. Location: Make sure there is room to open the HEPA filter access panel for filter changes/inspections. Keep the HEPA system away from possible water damage Vibration pads will reduce vibration for installations where the unit is placed on the floor. B Install HEPA System on floor or suspended platform. If the unit is suspended, screws must not penetrate through the cabinet. Make sure that you have the proper chains/straps/joists and equipment to keep unit secure. Intake (Marked as Air In on unit): Intake ducts should be installed near the floor for optimum airflow (see figure 11). If space does not allow, then the inlet can be installed in the ceiling. Intake duct should be installed at least 6 ft. away from the outflow duct. Intake duct should be installed at opposite end of the room from the outflow duct(s) if in the same room. Diffusers are recommended to help distribute airflow evenly. Outflow (Marked as Clean Air Out on unit): Outflow(s) should be installed in the ceiling away from any other air inlet(s) Room diffusers are recommended to help distribute airflow evenly in the occupied space. Ducting: If HEPA system is installed where inlet and outflow collars face down, metal elbows must be connected to both inlet and outflow collars. Each connection must be sealed with aluminum tape or mastic, including all vent connections. Installed duct runs should be as straight as possible (if the duct runs are too long, reduced CFM may result). If duct is exposed to unconditioned air, insulated flex duct is highly recommended. Externally insulated flex duct can also be used for noise reduction purposes. For best indoor air quality, do not use ductboard or fiberglass inside of ducts. Example of Single Room Stand Alone System Installation For single rooms where increased filtration is desired such as a dedicated smoking room. HEPA System A Figure 14.

54 Maintenance Proper care and maintenance of your HEPA system will ensure years of service. The unit must be turned off during service/maintenance or when filters are being changed. It is recommended that gloves and a filtered breathing mask be worn during filter replacement. Risk of Sharp Edges Hazard.! WARNING Electrical Shock Hazard. Can cause injury or death. Disconnect all electrical power supplies before servicing. Do not operate equipment without access panels in place! CAUTION Equipment sharp edges can cause injuries. Avoid grasping equipment edges without protective gloves. Filter Change Schedule Note: Note: Failure to properly maintain your HEPA system will decrease the efficiency and air flow. Pre-Filter: 3 to 4 months* HEPA Filter: 2 to 5 years Inner Carbon Filter: 6 months Optional Carbon Canister: 12 months * Foam pre-filters (AWW-350 & AWW-675) can be washed and reused NOTE: Filter life is based on average air content. Some filters may need to be changed more often due to higher amounts of dust, humidity, or chemicals found in your ambient air. Additionally, people who are more sensitive to these airborne contaminates may desire more frequent filter changes. Filter Changing Guidelines Pre-Filter: Dust and other large particles will collect on the pre-filter over time. The color of the filter will change as particulates build up on the pre-filter. Change the pre-filter when you can see the particulate build up start to clog up the pre-filter. HEPA Filter: As the HEPA filter captures particulates, it will darken over time. Replace the HEPA filter when it darkens to the level seen in example D. A. New B. Used C. Used D. Replace Inner Carbon Filter: The inner carbon filter will rarely look used. This filter captures odors and gasses, yet the filter s appearance will not change. When this filter has reached it s maximum adsorbancy of odors and gasses, it will no longer work. Replace this filter when it no longer seems to capture odors, or every 3 months (12 months for optional Carbon Canister), which ever occurs first. Pre-Filter HEPA Filter Inner Carbon Filter Figure

69 Model 471B Digital Thermo Anemometer Specifications - Installation and Operating Instructions Bulletin TE-471B 11/32 [8.74] PS/2 INPUT 29/32 [23.00] SLIDING COVER PS/2 CONNECTOR 2-13/16 [71.59] 16-11/64 [410.61] 6-11/64 [156.92] 6-9/64 [155.82] 6-31/32 [177.13] PROBE CABLE APPROX. 2 LG COILED APPROX. 6 LG EXTENDED 1-5/32 [29.36] The MODEL 471B Digital Thermo Anemometers are versatile dual function instruments that quickly and easily measure air velocity or volumetric flow plus air temperature in imperial or metric units. High contrast LCD display shows both selected readings simultaneously. Convenient backlight provides perfect visibility in low light conditions. Light automatically shuts off after 2-1/2 minutes to prolong battery life. Low battery warning is included. Stainless steel probe with comfortable hand grip is etched with insertion depth marks from 0 to 8 inches and 0 to 20 cm. Extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold even when taking multiple readings as part of duct traverses. Up to 99 readings may be stored for later retrieval. An integral sliding cover protects sensors when not in use. Items included with the 471B are 9 volt alkaline battery, sensing probe, wrist strap and custom carrying case. Battery Installation The unit is shipped with a separate 9 volt alkaline battery which must be installed before operation. Remove the two screws holding the bottom endcap in place and remove it. Connect the battery to the enclosed battery clip, observing correct polarity. Be careful not to trap the wires between the case or foam pad which retains the battery. This could make it difficult to install the battery or remove it later for replacement. Be sure the rubber gasket is properly seated in the gasket channel and replace the endcap. Note that the endcap will only fit one way because the holes are slightly offcenter. Place the Z shaped wrist strap clip in one of the screw recesses and replace the screws. Do not overtighten. Attach the wrist strap to the clip. When battery replacement becomes necessary, use only 9 volt alkaline type batteries such as a Duracell MN1604, or Eveready 522 or equivalent. Zinc-carbon types, often labeled Heavy-Duty, are not recommended because of their shorter life and an increased potential for leakage. Alkaline batteries are a better value because they last typically up to three times longer in this device. Low Battery Indicator A weak battery may cause improper operation or inaccurate measurements. A low battery indicator ( ) is provided on the display to show when the battery needs to be replaced.

89 ppbrae 3000 User s Guide Charging The Battery Always fully charge the battery before using the instrument. The instrument s Li-ion battery is charged by placing the instrument in its cradle. (The battery can also be charged by placing the instrument in an AutoRAE 2 Cradle.) Contacts on the bottom of the instrument meet the cradle s contacts, transferring power without other connections. Note: Before setting the instrument into its charging cradle, visually inspect the contacts to make sure they are clean. If they are not, wipe them with a soft cloth. Do not use solvents or cleaners. Follow this procedure to charge the instrument: 1. Plug the AC/DC adapter s barrel connector into the instrument s cradle. 2. Plug the AC/DC adapter into the wall outlet. 3. Place the instrument into the cradle, press down, and lean it back. It locks in place and the LED in the cradle glow The instrument begins charging automatically. The Primary LED in the cradle blinks green to indicate charging. During charging, the diagonal lines in the battery icon on the instrument s display are animated and you see the message Charging... When the instrument s battery is fully charged, the battery icon is no longer animated and shows a full battery. The message Fully charged! is shown. The cradle s LED glows continuously green. 15

90 ppbrae 3000 User s Guide Note: If you see the Battery Charging Error icon (a battery outline with an exclamation mark inside), check that the instrument or rechargeable battery has been set into the cradle properly. If you still receive the message, check the Troubleshooting section of this guide. Note: If the instrument or battery has been in the cradle for more than 10 hours and you see the Battery Charging Error icon and a message that says, Charging Too Long, this indicates that the battery is not reaching a full charge. Try changing the battery and make sure the contacts between the instrument (or battery) are meeting the cradle. If the message is still shown, consult your distributor or RAE Systems Technical Services. Charging A Spare Rechargeable Battery A rechargeable Li-ion battery can be charged when it is not inside the monitor. The charging cradle is designed to accommodate both types of charging. Contacts on the bottom of the battery meet the contacts on the cradle, transferring power without other connections, and a spring-loaded capture holds the battery in place during charging. 1. Plug the AC/DC adapter into the monitor s cradle. 2. Place the battery into the cradle, with the gold-plated contacts on top of the six matching charging pins. 3. Plug the AC/DC adapter into the wall outlet. The battery begins charging automatically. During charging, the Secondary LED in the cradle blinks green. When charging is complete, it glows steady green. Release the battery from the cradle by pulling it back toward the rear of the cradle and tilting it out of its slot. Note: If you need to replace the Li-ion battery pack, replacements are available from RAE Systems. The part number is

91 ppbrae 3000 User s Guide Note: An Alkaline Battery Adapter (part number ), which uses four AA alkaline batteries (Duracell MN1500), may be substituted for the Li-Ion battery. WARNING! To reduce the risk of ignition of hazardous atmospheres, recharge and replace batteries only in areas known to be non-hazardous. Remove and replace batteries only in areas known to be nonhazardous. Low Voltage Warning When the battery s charge falls below a preset voltage, the instrument warns you by beeping once and flashing once every minute, and the empty battery icon blinks on and off once per second. You should turn off the instrument within 10 minutes and either recharge the battery by placing the instrument in its cradle, or replace the battery with a fresh one with a full charge. Clock Battery An internal clock battery is mounted on one of the instrument s printed circuit boards. This long-life battery keeps settings in memory from being lost whenever the Li-ion battery or alkaline batteries are removed. This backup battery should last approximately five years, and must be replaced by an authorized RAE Systems service technician. It is not user-replaceable. Data Protection While Power Is Off When the instrument is turned off, all the current real-time data including last measured values are erased. However, the datalog data is preserved in non-volatile memory. Even if the battery is disconnected, the datalog data will not be lost. 17

92 ppbrae 3000 User s Guide User Interface The instrument s user interface consists of the display, LEDs, an alarm transducer, and four keys. The keys are: Y/+ MODE N/- Flashlight on/off The LCD display provides visual feedback that includes the reading, time, battery condition, and other functions. Display LEDs and flashlight Y/+ key N/- key MODE key Flashlight on/off key In addition to their labeled functions, the keys labeled Y/+, MODE, and N/- act as soft keys that control different parameters and make different selections within the instrument s menus. From menu to menu, each key controls a different parameter or makes a different selection. 18

93 ppbrae 3000 User s Guide Three panes along the bottom of the display are mapped to the keys. These change as menus change, but at all times the left pane corresponds to the [Y/+] key, the center pane corresponds to the [MODE] key, and the right pane corresponds to the [N/-] key. Here are three examples of different menus with the relationships of the keys clearly shown: 19

95 ppbrae 3000 User s Guide Operating The Instrument The instrument is designed as a broadband VOC gas monitor and datalogger for work in hazardous environments. It gives real-time measurements and activates alarm signals whenever the exposure exceeds preset limits. Prior to factory shipment, the instrument is preset with default alarm limits and the sensor is pre-calibrated with standard calibration gas. However, you should test the instrument and verify the calibration before the first use. After the instrument is fully charged and calibrated, it is ready for immediate operation. Turning The Instrument On 1. With the instrument turned off, press and hold [MODE]. 2. When the display turns on, release the [MODE] key. The RAE Systems logo should appear first. (If the logo does not appear, there is likely a problem and you should contact your distributor or RAE Systems Technical Support.) The instrument is now operating and performs self tests. If any tests (including sensor and memory tests fail), refer to the Troubleshooting section of this guide.

If you remove your finger from the key during the countdown, the shutoff operation is canceled and the instrument continues normal operation. Operating The Built-In Flashlight The instrument has a built-in flashlight that helps you point the probe in dark places. Press the flashlight key to turn it on. Press it again to turn it off. Note: Using the flashlight for extended periods shortens the battery s operating time before it needs recharging. Pump Status IMPORTANT! During operation, make sure the probe inlet and the gas outlet are free of obstructions. Obstructions can cause premature wear on the pump, false readings, or pump stalling. During normal operation, the pump icon alternately shows inflow and outflow as shown here: 22

97 ppbrae 3000 User s Guide During duty cycling (PID lamp cleaning), the display shows these icons in alternation: If there is a pump failure or obstruction that disrupts the pump, you will see this icon blinking on and off: If you see this blinking icon, consult the Troubleshooting section of this guide. Calibration Status The instrument displays this icon if it requires calibration: Calibration is required (and indicated by this icon) if: The lamp type has been changed (for example, from 10.6 ev to 9.8 ev). The sensor has been replaced. It has been 30 days or more since the instrument was last calibrated. If you have changed the calibration gas type without recalibrating the instrument. Bump Status The instrument displays this icon if it requires a bump test: 23

98 ppbrae 3000 User s Guide A bump test is required (and indicated by this icon) if: The defined period of time between bump tests has been exceeded (bump test overdue). The sensor has failed a previous bump test. The sensor(s) should be challenged on a periodic basis. Policy Enforcement The ppbrae 3000 can be configured to enforce a facility/company s requirements that calibration and/or bump testing be performed at specified intervals, and to explicitly prompt the user that calibration/bump testing is required. Depending on how Policy Enforcement features are configured, the user may be required to perform a bump test or calibration prior to being able to use the instrument. That is, it can be set to not allow normal operation of the instrument unless calibration or bump testing is performed. If the instrument has been bump tested and calibrated in compliance with the policy settings, a check-mark icon is included along the top of the ppbrae screen: If Policy Enforcement is enabled, then after startup the ppbrae displays a screen that informs the user that the instrument requires either a bump test or a calibration. If both are required, then they are shown in sequence. Note: Policy enforcement features are disabled by default. Setting Policy Enforcement You must use ProRAE Studio II to make changes to Policy Enforcement settings. You must use an AutoRAE 2 Cradle, a ppbrae 3000 Travel Charger, or a ppbrae 3000 Desktop Cradle. Policy violations are captured in the datalog. 24

108 ppbrae 3000 User s Guide Backlight The LCD display is equipped with an LED backlight to assist in reading the display under poor lighting conditions. Datalogging During datalogging, the instrument displays a disk icon to indicate that datalogging is enabled. The instrument stores the measured gas concentration at the end of every sample period (when data logging is enabled). In addition, the following information is stored: user ID, site ID, serial number, last calibration date, and alarm limits. All data are retained (even after the unit is turned off) in non-volatile memory so that it can be down- loaded at a later time to a PC. Datalogging event When Datalogging is enabled, measurement readings are being saved. These data are stored in groups or events. A new event is created and stored each time the instrument is turned on and is set to automatic datalogging, or a configuration parameter is changed, or datalogging is interrupted. The maximum time for one event is 24 hours or 28,800 points. If an event exceeds 24 hours, a new event is automatically created. Information, such as start time, user ID, site ID, gas name, serial number, last calibration date, and alarm limits are recorded. Datalogging sample After an event is recorded, the unit records a shorter form of the data. When transferred to a PC running ProRAE Studio, this data is arranged with a sample number, time, date, gas concentration, and other related information. 34

You will see the following message: Updating settings The instrument updates its settings and then returns to the main display. It begins or resumes monitoring. Bump Test RAE Systems recommends that a bump test be conducted prior to each day s use. The purpose of a bump test is to ensure that the instrument s sensors respond to gas and all the alarms are enabled and functional. The ppbrae 3000 must be calibrated if it does not pass a bump test when a new sensor is installed, after sensor maintenance has been performed, or at least once every 180 days, depending on use and sensor exposure to poisons and contaminants. Calibration and bump test intervals and procedures may vary due to national legislation and company policy. To perform a bump test (functional challenge), follow these steps: 1. Select Bump. 2. Install the calibration adapter and connect it to a source of calibration gas. 3. Verify that the displayed calibration value meets the concentration specified on the gas cylinder. 4. Start the flow of calibration gas. 5. Press [Y/+] to start the bump test. 51

126 ppbrae 3000 User s Guide 6. You can abort the calibration at any time during the countdown by pressing [N/-]. 7. If the calibration is not aborted, the display shows reading and then tells you whether the bump test passed or failed. If the bump test failed, then it automatically advances to the Calibration screen. A bump test can be performed either manually or using the AutoRAE 2 Automatic Test and Calibration System. When a bump test is done manually, the instrument makes a pass/fail decision based on sensor performance, but the user still has the responsibility to make sure all the alarms are enabled and functional. Note: Bump testing and calibration can be performed using an AutoRAE 2 Automatic Test & Calibration System. An AutoRAE 2 bump test takes care of both the sensor and alarm tests. Consult the AutoRAE 2 User s guide for details. The same gas is used for a bump test as for calibration. The instrument must be connected to a cylinder of calibration gas with supplied tubing. IMPORTANT! If the instrument does not pass a bump test, perform a full calibration. If calibration also fails, the PID sensor or lamp may require cleaning or replacement. If the instrument repeatedly fails to calibrate, turn it off and refer it for servicing. Important! Anytime a bump test fails, you should perform a full calibration of the instrument. 52

177 ppbrae 3000 User s Guide Sampling Pump When approaching the end of the specified lifetime of the pump, it will consume higher amount of energy and reduce its sample draw capability significantly. When this occurs, it is necessary to replace or rebuild the pump. When checking the pump flow, make sure that the inlet connector is tight and the inlet tubing is in good condition. Connect a flow meter to the gas inlet probe. The flow rate should be above 450 cc/min when there is no air leakage. If the pump is not working properly, refer the instrument to qualified service personnel for further testing and, if necessary, pump repair or replacement.

193 Technical Note TN /16/VK A GUIDELINE FOR PID INSTRUMENT RESPONSE CORRECTION FACTORS AND IONIZATION ENERGIES* RAE Systems PIDs can be used for the detection of a wide variety of gases that exhibit different responses. In general, any compound with ionization energy (IE) lower than that of the lamp photons can be measured.* The best way to calibrate a PID to different compounds is to use a standard of the gas of interest. However, correction factors have been determined that enable the user to quantify a large number of chemicals using only a single calibration gas, typically isobutylene. In our PIDs, correction factors can be used in one of three ways: 1. Calibrate the monitor with isobutylene in the usual fashion to read in isobutylene equivalents. Manually multiply the reading by the correction factor (CF) to obtain the concentration of the gas being measured. 2. Calibrate the unit with isobutylene in the usual fashion to read in isobutylene equivalents. Call up the correction factor from the instrument memory or download it from a personal computer and then call it up. The monitor will then read directly in units of the gas of interest. 3. Calibrate the unit with isobutylene, but input an equivalent, corrected span gas concentration when prompted for this value. The unit will then read directly in units of the gas of interest. * The term ionization energy is more scientifically correct and replaces the old term ionization potential. High-boiling ( heavy ) compounds may not vaporize enough to give a response even when their ionization energies are below the lamp photon energy. Some inorganic compounds like H 2 O 2 and NO 2 give weak response even when their ionization energies are well below the lamp photon energy. Example 1: With the unit calibrated to read isobutylene equivalents, the reading is 10 ppm with a 10.6 ev lamp. The gas being measured is butyl acetate, which has a correction factor of 2.6. Multiplying 10 by 2.6 gives an adjusted butyl acetate value of 26 ppm. Similarly, if the gas being measured were trichloroethylene (CF = 0.54), the adjusted value with a 10 ppm reading would be 5.4 ppm. Example 2: With the unit calibrated to read isobutylene equivalents, the reading is 100 ppm with a 10.6 ev lamp. The gas measured is m-xylene (CF = 0.43). After downloading this factor, the unit should read about 43 ppm when exposed to the same gas, and thus read directly in m-xylene values. Example 3: The desired gas to measure is ethylene dichloride (EDC). The CF is 0.6 with an 11.7 ev lamp. During calibration with 100 ppm isobutylene, insert 0.6 times 100, or 60 at the prompt for the calibration gas concentration. The unit then reads directly in EDC values. Conversion to mg/m3 To convert from ppm to mg/m3, use the following formula: For air at 25 C (77 F), the molar gas volume is 24.4 L/mole and the formula reduces to: RAE Systems by Honeywell raesystems.com 1
