Valve and Gauge Panel Connections Limit Switches The High Pressure limit switch is wired to the Normally Closed terminals on the top of the switch. The switch is factory preset to shut-down at 850 psi. Do not adjust the high pressure limit switch without consulting the factory first. The Feed Pressure limit switch is also wired to the Normally Open terminals on the top of the limit switch. The Feed Pressure switch is factory set to close when the feed pressure exceeds 10psi. Do not change the settings on this switch without consulting the factory first. The system will not run unless the Feed Pressure is over 10psi as the switch must be closed to complete the run circuit. Membrane Pressure Connect one end of the supplied 1/4 high pr essur e tubing to the 1/4 compression fitting on the membrane end cap and connect the opposing end to the back of the Membrane Pressure Gauge (see picture on previous page). Follow the instructions on pg. 17 for fitting assembly instructions. Filter Condition Gauge Located on the inlet and outlet of the 5 micr on pr e-filter housing are 2 Parker Fast and Tight connections. Connect the supplied1/4 Low Pressure tubing to each of these fittings. Lead the tubing from the inlet side of the prefilter to the fitting on the 1/4 3-way valve on the backside of the control panel marked in Red. Connect the tube from the outlet fitting of the 5 micron filter to the outlet fitting on the same 3-way valve marked in Green. Product Inlet Connect one end of the supplied 1/2 low pr essur e tubing to the pr oduct outlet fitting located on the membrane end cap to the Product Water Inlet fitting on the backside of the Control Panel. Product Outlet Connect one end of the supplied 1/2 low pressure tubing from the product water outlet on the backside of the Control Panel to the fresh water supply tank (not included) for distribution. There should not be valves in the product line that allow you to stop the product flow, it can be redirected by using an always open 3 way valve but a shutoff valve will destroy the membranes if it left closed. The Product outlet should always be open to atmosphere. Seawater Inlet Connect the supplied 5/8 low pr essur e tubing fr om the Outlet of the 5 micr on filter housing to the Seawater Inlet fitting on the 1/2 3-way valve on the backside of the Control Panel. Fresh Water Inlet Connect one end of the supplied 1/2 nylon braided hose to the Fresh Water Inlet on the 1/2 3-way valve on the backside of the Control Panel to a pressurized, un-chlorinated fresh water source. This water will serve as the fresh water flushing supply source. Feed Water Outlet Connect one end of the supplied 3/4 nylon braided pressure hose to the 3/4 hose barb fitting on the backside of the Control Panel, connect the opposing end of the nylon hose to the feed water inlet of the Spectra Pearson Pump on the high pressure assembly. 6

COMPONENT DESCRIPTIONS The Spectra LB-1800/2800 watermaker is designed to be installed in a building or pump house so the system is not exposed to the elements. Feed water must be supplied to the unit at 6gpm (22 lpm) at a minimum of 10psi (0.7bar) and a maximum of 20psi (3.5 Bar). Feed water should be pre-filtered to 50 microns before going through the Spectra supplied pre-filter. The watermaker separates the feed stream into a product and a brine streams. The brine contains the concentrate left over after the product water is removed, and Brine flow may be as high as 6.5 gpm (25L/min) depending on the running speed of the Spectra-Pearson Pump. The brine should be discharged to a drain at least 8ft. (2.5m) above the pump head to provide a small amount of back pressure on the pump which helps with operating efficiency. If this is not possible a valve can be installed on the brine discharge line to create the required back pressure. Consult with your local government agency for more information about the best brine disposal system for your application. 20 Prefilter Housing Contain the 5 micron feed water prefilter and housing and should be mounted within 10 feet of the Control Panel. It is designed to be mounted to a wall and should be installed higher than the Feed Pump Module. Allow 3 4 of clearance on the bottom of the filter bowl to easily remove the filter housing when changing filters. Do not install the prefilter module over any electrical device or outlet as some water will be spilled during filter changes. Spectra Pearson Pump High Pressure Module This module contains the Spectra Pearson Pump, Oil pump and filter assembly, and two 4 x 40 seawater membranes. All high pressure fittings between the membranes and the pump come preassembled and connected field serviceable JIC 37 deg. female flare fittings. It is possible to remote mount the Spectra Pearson Pump from the pressure vessels by obtaining a longer section of hose from the factory. Consult your nearest distributor if you need to order longer hoses for special installations. The Spectra Pearson Pump MUST be installed in an upright position, with the vented oil cap facing up. 8

COMPONENT DESCRIPTIONS The Valve and Gauge Panel has a series of analog gauges and valves mounted for easy reference to system operation. There are two flow meters, one to measure the inlet flow from the feed pump and the other to measure the product water flow rate. One three-way valve controls the feed water source to switch between running and flushing. The three way valve on the right is connected to the filter pressure gauge and allows you to switch between measuring the inlet and outlet pressure to quickly determine the condition of the prefilter. A new filter should show no pressure difference and you should change the filter when the pressure difference is more than 5 psi. Control Box The FRP watertight box (when corner screws are used) contains the electrical controls for the unit: start/stop run and flush speeds and a circuit breaker, This box should be mounted away from any water source or where it could get sprayed or wet. Should the need arise to open the electrical box after installation, use caution as there are live electrical wires inside. It is always recommended you disconnect all power to the unit before opening the control box. 9

un T Spectra High Pressure Tube Fitting Assembly Use ONLY Dayco Imperial Nylo-Seal 88-NSR-1/2 tubing for high pressure connections. Carefully fit and measure the tubing before cutting with a sharp razor knife or hose cutter and remove any burrs. Minimum tubing bend radius is 6. Route tubing away from excessive heat sources and secure from vibration and chafe. Have at least one shallow bend in a tube assembly after it is installed. Refer to figure 1. If a fitting has been dissembled, reassemble as illustrated. The notch on the ferrule must engage the inside of the nut properly for the nut to seat down fully. Once the tube is inserted the ferrule and nut will naturally align. Refer to figure 2. Insert tube fully into the fitting, it should go in 0.9. Tighten the nut finger tight while moving the tube around to prevent binding. One thread should be showing under the nut. Secure the tube so it won t back out when tightening. Refer to figure 3. Use 13/16 wrench to hold a straight body fitting or a 3/4 wrench for a 90º body, and a 7/8 wrench for the nut. Hold the body, recheck the tube insertion, then tighten the nut 1-1/4 turns. Use the index mark on the nut as a guide. The threads should be completely covered by the nut. Make Sure these fittings are tight on initial assembly or they will fail!

Note Well: when the plumbing is completed if feed is water is pouring from the brine discharge there are two options. Either the brine discharge drain is raised until water stops flowing (with the feed tank full) or a ball valve is installed in the feed line. Free flowing feed means the system will drain the feed tank and will not flush properly.

Initial Startup (Purging Storage Solution) Note: The crankcase in this unit shipped from the factory with oil in the crankcase and a shipping plug in the dipstick hole. Remove the plug and install the dipstick before operating the watermaker. Confirm that the crankcase is roughly half-full of oil before starting the watermaker. When starting the machine for the first time insure the product water is going to a drain until it becomes potable. Ensure that there are filters in the filter housing(s). Set the Feed water valve in RUN position and the filter condition selector valve to IN so it will measure the boost pressure on start up. Open the pressure relief valve on the Pearson Pump 1 turn. Turn on the power and turn the power switch on the control box to ON. Set up the feed water pump and turn it on and ensure that there is 10 to 20 psi (max) and at least 6 gpm available at the Feed Water Inlet. Bleed Pre-Filter of any air (see picture opposite) Note that the system will not run if the feed pressure is below 10psi as this is required to To start the Purge cycle set the Run switch on the electrical box in the On Position and hold the Start switch in the up position until the feed water pressure reaches 10 PSI. When the pressures and flows have stabilized adjust the pump speed control knob until the Feed flow meter reading is about 4.5 GPM. DO NOT EXCEED 60 PSI MEMBRANE PRESSURE WHILE PURGING OR DAMAGE TO THE MEMBRANE WILL OCCUR!! Run the watermaker for at least one hour with the pressure relief valve open to Purge the preservatives from the membranes. After one hour close the pressure relief valve and water will begin to flow out of the Product hose. Discard this water for at least 20 minutes. After 20 minutes test the water for salinity and taste. When the salinity is good and the water tastes acceptable, turn off the Run switch and restart the watermaker according to the Normal Operation Instructions, or fresh water flush the watermaker if the machine will not be used until later. 21

Normal Operation Note: If the system contains preservative or antifreeze, or if the condition of the membrane is unknown, follow the Initial Startup (purging) instructions on the previous page. When in doubt, Purge the system. Starting: Set the product sampling valve to send the product to a drain. Turn the feed valve to the Flush position (see picture opposite). Set the Pump Speed Control to Zero. All valves in the product line must be open and unobstructed. flow freely at all times. Product must be allowed to Make sure there is power to the external supply pump. Turn the power switch to the Run position and hold the Start switch up until the feed pressure exceeds 10psi (0.7Bar). When the pressures and flow rates have stabilized, adjust the Pump Speed Control to increase the production and membrane pressures to 5.5 GPM feed flow, as read on the control panel. **Consult the factory if it is necessary to adjust the feed flow by more than 10% above or below the factory recommended flow rate. DO NOT EXCEED 850 PSI MEMBRANE PRESSURE!! After about one minute water will begin to flow out of the product hose. Test the product with the supplied hand held salinity tester. If it is within acceptable range it may be distributed as potable water. Operation: Monitor the Filter Pressure gauge during operation. Pressure drop across the filter can be determined turning the valve from IN to OUT and comparing the gauge reading and here should be very little difference when the filter is new and clean. The pressure differential begins to climb the as the filter clogs and when the differential has increased by 5psi (0.35 bar) the prefilter should be changed. If the Filter Outlet Pressure drops below 10psi (0.7 bar), the machine will stop. Monitor the sound of the Spectra Pearson Pump. If the feed pump makes a heavy knocking noise, or very loud rattling noise it is cavitating or there is air in the feed water. Excessive cavitation or air in the feed water inlet will permanently damage the pump. Stopping: Stop the machine at any time by turning the Run switch down to the Off position. 22

Fresh Water Flushing If the machine is to be turned off for more than 12 hours it should be flushed with unchlorinated fresh water. This process should be repeated once every 5 7 days, depending on climate (shorter cycle in warm climates), that the machine is not in use. Turn off the feed water supply pump and close the feed water inlet valve if fitted, to ensure that no raw water is drawn in during the flush. Turn the Flush Valve to the Down position, covering the Run label and exposing the Flush label. Turn on the Flush Switch on the Control Box. The machine will start and water will flow from the brine hose. Stop the machine when the brine discharge water salinity is below 1,000ppm (1,000 mg/l). Flush Valve in Fresh Water Flush position 23

Maintenance General In installations where the unit is running 24/7 it is prudent to perform a visual inspection at the very least weekly. Pressures and flow rates should be recorded in the log for reference. Repair any leaks as soon as possible. Periodically inspect the entire system for leaks and any chafing on the tubing and hoses. Check for corrosion around the fittings. If any rust or corrosion appears around fittings, remove, clean, and reassemble the fitting. Rust is a sign of crevice corrosion inside the fitting and must be dealt with promptly or the fitting will fail. Some salt crystal formation around the layers of the Pearson Pump mating surfaces is normal. Wash down any salt encrusted areas with a damp cloth. Keep the all the watermaker components clean, dry, and salt free. Pearson Pump Maintenance Intervals The high & low pressure seals should be replaced every 2500 hours. This can be done with the pump in place in about one hour, order (KIT-SPP5-20-SOK). Inspect belt drive for wear. The Oil and Filter should be changed every 5000 hours. For Filter order (FT-FTC-1/4LFD) The Pearson Pump head should be rebuilt at 10,000 of operation. This can typically be done in about three hours, order (KIT-SP5-20R10K) The 5 Micron Filter A clogged pre-filter will cause the controls to shut down the watermaker. Avoid letting the filters to get so dirty the unit shuts down automatically. After a filter change it may be necessary to expel the air from the feed line using the purge button, located on top of the 5 micron filter lid. When the system is put into storage, remove, rinse, and re-install the 5 micron filter dry to impede corrosion. The 5 micron filter must be properly maintained to protect the Spectra Pearson Pump. Use only Spectra approved filters. Use food grade silicone grease on the o-ring to ensure a proper seal between the filter bowl and lid. Do not use any petroleum based product, such as Vasoline or mineral oil, as it will cause the filter housing bowl to fail. 24

GEARCASE OIL MAINTENANCE Use only 5W-30 synthetic oil in Pearson Pump crankcase. Do not overfill the crankcase with oil. Check oil condition and level frequently. The Oil and Filter should be replaced every 5000 hours or annually, whichever comes first. The Spectra Pearson Pump comes mounted on a counterclockwise rotating CAT crankcase with integrated oil pump and filter. This system is designed for easy maintenance with long intervals between required oil changes. Inspect the oil level and condition often, any milky appearance means the seals need to be replaced and the oil changed immediately. The oil in the crankcase should be changed every 5,000 hours or when the oil appears milky. There is an inspection window that is visible from the plumbing manifold side of the Spectra- Pearson Pump, or the dipstick on the top of the crankcase. Oil Filter Oil Pump Vented Oil Cap Oil Pump Outlet Tube Inspection Window Oil Change Button is behind motor CHANGING THE OIL 1. Place a container in or near the Spectra-Pearson Pump Module that can hold up to 2 pints of liquid. 2. Disconnect the Oil Pump Outlet tube from the filter and lead it to the container. 3. With DC power to the Control Box on, press the Oil Change Button on the top of the crankcase. 4. Run the small oil pump manually until no more oil comes out of the tube. 5. Replace the filter with new, p/n FT-FTC-1/4FLFD, and reconnect tubing, and plug. See instructions included with oil change kit for more detail. 6. Using a small funnel fill the crankcase with oil until the level reaches the halfway point on the inspection window, or the marked line on the dipstick. Run the oil pump to fill the filter with oil and add oil until the oil is at the correct level. Replace the vented dipstick. 25

Long Term Storage If the machine will not be used for more than seven days it should be treated with preservative. Spectra Watermakers Preservative SC-1 powdered preservative may be used if there is no danger of freezing. Do not use other brands of preservative, they will damage the equipment! If there is danger of freezing Propylene Glycol potable water antifreeze should be used instead of Spectra Watermakers SC-1. The Pressure Relief Knob on the Spectra Pearson Pump must be open while circulating preservatives or cleaning compounds! If SC-1 chemical is to be used: You will need 2 cans of SC-1, 5 gal. (20L) of chlorine free water and the system must have already been thoroughly flushed. The feed water supply must be shut off. Mix two cans of Spectra Watermakers SC-1 chemical into the unchlorinated water, stir until well dissolved. Attach the intake and discharge service hoses to the corresponding connectors on the service valves. Place the intake service hose and the brine discharge service hose into the bucket with the storage chemical mixture. Open the pressure relief valve on the Spectra Pearson Pump. Turn the Flush switch up to the On position. The preservative will begin to circulate. Circulate the solution for about ten minutes. Push the Stop button. Remove the brine hose from the bucket and put it in a drain. Turn on the Flush switch again. The machine will pump the remaining solution to the drain. Turn the flush switch to the Off position when the bucket is empty. Leave the pressure relief knob open. The watermaker can now be stored for up to six months. If the machine has not been used for six months the preservative procedure should be repeated. 26 Note: Color of dot may vary. Consult product label to ensure proper chemical is being used.

Storing with Antifreeze (Winterizing) You will need approximately 5 US gal (20L) of Propylene Glycol potable water antifreeze*. The system must have been fresh water flushed thoroughly. Open the Pressure Relief Knob! Attach the intake and discharge service hoses to the corresponding connectors on the service valves. Place the intake service hose into the bucket with the propylene glycol. Lead the brine discharge service hose to a drain. Turn the Flush switch on the control box to the On position. Water will begin to flow out of the brine hose into the drain. When antifreeze begins to come out of the brine hose turn the Flush switch to the Off position. Place the end of the brine hose in the bucket with the propylene glycol. Turn the Flush switch on again to begin circulating the antifreeze. Circulate the antifreeze for 10 minutes. Turn the Flush switch off. Put the end of the brine hose to the drain again. Turn on the Flush switch. The system will pump the antifreeze in the tank into the drain. Turn the flush switch off when the bucket is empty. Leave the pressure relief knob open. The 5 micron prefilter can be removed and the filter housing left empty at this point**. *USE THE MOST CONCENTRATED FORMULA PROPYLENE GLYCOL AVAILA- BLE, 100 FORMULA OR GREATER CONCENTRATION. ** Be sure to replace the 5 micron filter before running the system again. 27

The Membranes Membranes need to be cleaned only when feed pressures have risen 10% or production has dropped 10% due to fouling, or if the product quality degrades. Causes of fouling are: Biological growth that occurs when the system is left unused without flushing or pickling, mineral scaling if the feed water contains carbonates, sulfates, silicates or other sparingly soluble salt, or Colloidal particles can also clog the membrane. Monitor and keep a log of the product salinity and feed pressure for higher than normal readings for the conditions. Look for all other causes before cleaning the membrane, i.e. feed water temperature and salinity, pump speed, hose restrictions as Membrane life can be shortened by unnecessary cleaning. There are two types of cleaners: acid and alkaline; Acid cleaner (SC-3) will remove mineral scaling. Alkaline cleaner (SC-2) is used to remove biological by-products, oil, and dirt particles that get past the prefilters. The acid cleaner should be used first. If the membrane fails to respond to both cleanings, this is an indication of another problem with the system, or that it is time to replace the membrane. Contact Spectra Watermakers before removing a membrane. Membrane Cleaning For normal cleaning, the SC-3 Acid Cleaning Compound is used first, then the SC-2 Alkaline Cleaning Compound. If known bio-fouling is present, the SC-2 may be used first. Using warm water if possible, up to 120 F (50ºC) is recommended as it greatly enhances the ability of the cleaners to do their jobs. Note: Procedures are the same for the SC-2 and SC-3 cleaners. Warning! The pressure relief valve on the Spectra Pearson Pump must be open for this procedure or membrane damage may result. Spectra Cleaning Compounds (SC-2 or SC-3) must be mixed with unchlorinated fresh water at a ratio of 1 container of compound to 3 gallons (12L) of water to have the proper solution. About 4 gallons (16L) of water is already present inside an 1800 system. This water has to be figured into the mixture. An 1800 system will use 2 containers of compound. SC-2 and SC-3 are never mixed together. Do not use them for storage pickling solution. 28

Cleaning Procedure: You will need 5 gal (20 L) of chlorine free water and the system must have already been thoroughly flushed. Mix two cans of Spectra Watermakers cleaning chemical into the water and stir until well dissolved. Some chemical may remain out of solution in the bucket, this is normal. Position the bucket as high and as close as possible to the Spectra Pearson Pump. Do not perform this procedure with the bucket more than 2 feet below the inlet to the Spectra Pearson Pump. Open the Pressure Relief Valve. Install the inlet service hose and the brine discharge service hose on the corresponding service valves and lead them into the bucket containing the cleaning solution. If possible, heat the solution to 120 F (50 C) to provide maximum cleaning power. Turn the Flush switch to the On position. The cleaning chemical will begin to circulate. Circulate the solution for about ten minutes. If heating the solution is not possible, allow the system to soak for several hours. Occasionally start the pump by turning on the flush switch to agitate the solution. When finished cleaning, remove the brine hose from the mixture and put it in a drain. Turn the flush switch on again to pump the remaining solution to the drain. Turn the Flush switch off when the bucket is dry. Remove and replace intake hose so the system is now setup for normal operation. When putting the system back into service, follow the Purge instructions for New System Startup. 29
