19 SECTION 3 4. SYSTEMS NOTE: Read and understand this section of the manual entirely before proceeding. This portion of the manual divides the unit up into systems and describes how each system works. Prior to proceeding into the operations and maintenance sections of this manual it is recommended that you acquire a basic understanding of how the unit functions. WATER/HEATING SYSTEM Cold water enters the console through the water inlet connection located on the lower left corner of the lower front panel. The water then flows to the water box through a float valve, which shuts off the water when the water box is full. The water is pre-heated in the water box using radiant heat generated by the vacuum blower and the engine. The water then flows to the water pump where it is pressurized. From there it flows to the heat exchanger where it travels through finned tubing and is further heated by the vacuum blower and engine exhaust.. The hot water then flows through the check valve manifold that contains a strainer and a check valve. At this point, the chemical injection takes place. The hot solution mixture of water and chemicals then flows through the solution outlet manifold to the cleaning tool. 3-1 SAPPHIRE SCIENTIFIC MODEL 370 SS 15

20 SECTION 3 VACUUM SYSTEM The engine turning an air pump (vacuum pump) generates vacuum. The air is channeled in one side of the vacuum pump, compressed and discharged on the opposite side, creating airflow. This airflow is used to do the work necessary for the extraction process. A vacuum nozzle applied to the carpet surface removes moisture, dirt and spent chemicals. These elements are conveyed back to a separating tank utilizing hoses and the force of air. Particles of moisture and dirt are separated in the vacuum tank using a series of changes in direction and velocity. The air is then filtered and rushes into the vacuum pump. The vacuum pump also heats incoming air as it is compressed. The hot discharged air is forced down stream into a silencer for noise abatement. Exiting the silencer, this hot air is directed through the heat exchanger The vacuum pump speed is factory set to maximize vacuum pressure and provide sustained system life. Do not alter the vacuum speed outside the recommended range shown in the Technical Specifications section. A level shut off sensor is located near the top of the waste tank and will shut down the unit before the tank is at full capacity. This protects the vacuum pump from water damage. Note: Waste tank level shut off will not shut the unit off due to high levels of foam. The use of a quality defoamer is recommended. 16 SAPPHIRE SCIENTIFIC MODEL 370 SS

21 SECTION 3 CHEMICAL PUMPING SYSTEM The chemicals are drawn from the chemical container through a strainer into the flow meter mounted on the control panel. The flow meter indicates the rate of chemical flow. The chemical then flow through the stainless steel chemical pump, the chemical is then injected into a three way selector valve located on the front panel. This valve may be used to turn the chemical flow ON, OFF, or to PRIME the chemical pump. 3-2 The chemicals then flow through the chemical metering valve to the solution outlet. This valve controls the rate of flow of chemical into the cleaning solution, which is indicated on the flow meter SAPPHIRE SCIENTIFIC MODEL 370 SS

22 SECTION 3 5. OPERATION PREPARATION This section of the operator s manual explains how to prepare, start, operate, shut down and maintain your SAPPHIRE SCIENTIFIC MODEL 370 SS mobile cleaning unit. The MODEL 370 SS unit is easy to operate, however only trained operators should proceed.! Operate this unit and equipment only in a well ventilated area. Exhaust fumes contain carbon monoxide, which is an odorless and deadly poison that can cause severe injury or death. DO NOT run this unit in an enclosed area. DO NOT operate this unit where the exhaust may enter a building doorway, window, vent or any other opening. 18 SAPPHIRE SCIENTIFIC MODEL 370 SS

23 SECTION 3 ENSURE THERE IS ADEQUATE FUEL Check the fuel tank to ensure there is adequate fuel to complete the job and transport the vehicle. This unit consumes approximately 1 US gallon of fuel per hour, depending on the speed setting. REMOVE TOOLS FROM THE VEHICLE Remove any tools, accessories or hoses from the vehicle that you will require. WATER SUPPLY CONNECTION NOTE: Never use a waste pump outlet hose as a water inlet hose. Use only clean hoses for water supply. 2. Turn the water supply faucet on. Water will fill the water box. HIGH PRESSURE HOSE Before starting the unit, connect the high pressure hose to the solution outlet connection at the front of the unit. Connect the cleaning tool to the opposite end of the pressure hose. NOTE: Prior to connecting your water inlet hose to any supply faucet, flush out the faucet until the water is free of any debris. Also, flush out any debris from your water inlet hose. 1. Connect the water supply hose to the water inlet quick connector on the front of the unit. Connect the hose to the faucet. SAPPHIRE SCIENTIFIC MODEL 370 SS 19

24 SECTION 3 STARTING THE UNIT! 1. Set throttle control in, pull out engine choke, turn solution pump switch to override and turn ignition key to start. 2. Push in engine choke after engine has started. 3. Set throttle control to maximum. Note: Do not operate the unit with throttle control set below 50% of maximum throttle setting. 4. Turn the water pump switch to the ON position. NOTE: If the unit does not build water pressure after 5 seconds, check for adequate water supply. See Loss of Water Pump Pressure in the Troubleshooting section of this manual. 5. Cover the vacuum inlet port for 2 to 3 minutes allowing the water temperature to warm up before cleaning. VACUUM HOSE Connect the vacuum hose(s) to the vacuum inlet connection at the front of the unit. Connect the opposite end of the vacuum hose(s) the cleaning tool. SAPPHIRE SCIENTIFIC recommends that the total floor tool size does not exceed #4. Using larger jet sizes on your MODEL 370 SS unit may reduce cleaning temperatures. PRIMING THE CHEMICAL PUMP NOTE: SAPPHIRE SCIENTIFIC recommends that the chemical pump be primed whenever the water pump is on. This eliminates possible pressure fluctuations and water pump pulsations related with running the chemical pump dry. 1. Insert the chemical prime tube and the chemical inlet tube into the chemical container. NOTE: When inserting the chemical tube into the chemical container, ensure that it stays submerged, as the chemical pump will not function if air is allowed to enter the inlet line. 2. Turn the 3-way chemical selector valve located on the control panel to the PRIME position. The chemical will then flow from the chemical container through the chemical prime tube. If the pump does not prime, then: Place the chemical prime tube into the vacuum hose and seal off the vacuum hose. The vacuum will quickly draw chemical 20 SAPPHIRE SCIENTIFIC MODEL 370 SS

25 SECTION 3 from the chemical container. After the flow begins, turn the chemical selector valve to OFF position, insert the chemical prime tube back into the container, and turn the chemical selector valve back to the PRIME position and continue the procedure. 3. When the chemical flows with no air bubbles, priming has been achieved. Turn the chemical selector valve from PRIME to METER. With the cleaning tool open, check the flow meter and adjust the chemical metering valve until the desired rate of chemical flow is achieved. AUTOMATIC WASTE PUMP 1. If your unit is equipped with an optional automatic waste pump, connect one end of the ⅝ in. or larger garden hose to the pump-out connection and the other end to an acceptable waste disposal. 2. Turn the pump-out switch located on the front console control panel to the ON position. The waste pump will now operate automatically throughout the cleaning period. DO NOT use an outlet hose that is smaller than ⅝ in. I.D. NEVER use a waste pump hose as a water inlet hose.! NEVER dispose of waste water in a storm drain, water way or on ground areas. Always dispose of waste in accordance with Local, State and Federal laws. OPERATION After you have completed the previous steps, proceed with the cleaning or restoration operation. Place the throttle control cable to a minimum of 50% of throttle control maximum for cleaning or restoration. A float shut-off switch is located inside of the waste tank. It will automatically shut down the unit if the tank reaches its full capacity. If this occurs, empty the waste tank before continuing. When doing flood extraction, the water pump should be in the OFF position. NOTE: During flood extraction it is recommended the throttle control is set to maximum. CLEANING While cleaning, observe the following guidelines: 1. Before cleaning, ensure that the wand nozzles are functioning properly. A. Hold the wand approximately one foot above the surface to be cleaned and open the wand valve. A full even spray should emit from the cleaning nozzles. B. If the nozzles are not showing a full even spray pattern, adjust, clean, or replace the nozzles, if required. 2. Usually, chemical solution is applied during the push stroke of the wand during cleaning, and extraction is done on the pull stroke. For heavily soiled carpets, the wand may be used in a scrubbing action, with chemical solution applied in both push and pull strokes, provided that the final stroke is a pull stroke with no chemical injection. UPHOLSTERY CLEANING 1. Upholstery tools have a lower flow rate and smaller orifices. Adjust the thermostatic temperature control to the desired temperature. To maintain proper cleaning SAPPHIRE SCIENTIFIC MODEL 370 SS 21

Select the viscosity based on the air temperature at the time of operation as shown in the following table.! DO NOT attempt to service this unit while it is running. High speed parts as well as high temperature components may result in severe injury, severed limbs, or fatality. NOTE: Refer to the hour meter as a guide for coordinating a maintenance schedule. NOTE: Using a lower service class oil or extending oil change intervals longer than recommended can cause engine damage. NOTE: Synthetic oils meeting the listed classifications may be used with oil changes performed at recommended intervals. However to allow piston rings to properly seat, a new or rebuilt engine should be operated for at least 50 hours using standard petroleum based oil before switching to synthetic oil. 3. Check the spark plugs every 200 hours and clean if necessary. Replace spark plugs every 1000 hours. NEVER sandblast spark plugs. Spark plugs 28 SAPPHIRE SCIENTIFIC MODEL 370 SS

33 SECTION 4 should be cleaned only by scraping or wire brushing. 4. Clean the engine air filter element every 200 hours. Replace the element every 1000 hours. Replace the in-line fuel filter yearly. NOTE: Additional engine service information can be obtained from the provided Kohler Operation and Maintenance manual. If service or repair is required, contact an authorized Kohler Service Center. They will require the serial number of the engine. VACUUM PUMP NOTE: Refer to the provided Vacuum Pump Operation and Service Manual for specific instructions. Lubrication: SAPPHIRE SCIENTIFIC recommends that you use only AEON PD-XD Synthetic Blower Lubricant in both sides of the vacuum pump for all operating temperatures. AEON PD-XD is formulated specifically for positive displacement blower service to provide maximum blower protection at any temperature. One filling of AEON PD-XD will last a minimum of twice as long as a premium mineral oil. NOTE: AEON PD-XD (Part # ) is the only oil that SAPPHIRE SCIENTIFIC puts in the vacuum pump at the factory. Adding petroleum oil to synthetic oil is NOT recommended. 1. Check the oil level weekly on both sides to ensure they are at the proper level. Too little oil will damage and ruin the bearings and gears. Too much oil will result in overheating. 2. A lubrication cup has been provided at the front of the console, to prevent rust from building up inside of the vacuum pump. Run the unit for at least 2 minutes to remove any moisture from the vacuum pump. Then, spray WD- 40 (or Equivalent) into the lubrication cup for 5 seconds while the unit is running and the vacuum inlet port is sealed. This procedure should be done at the end of every working day. 3. Drain, flush and replace the oil every 1000 hours or yearly, whichever comes first. NOTE: Two drains are on your vacuum pump. Ensure that both sides of the vacuum pump are filled to their proper level when servicing. WATER PUMP Refer to the provided Water Pump Operation Manual for specific instructions. 1. Check the crankcase oil level daily to ensure the proper level. If the level has dropped, check for the source of leakage and repair. SAPPHIRE SCIENTIFIC MODEL 370 SS 29

CHEMICAL METERING SYSTEM Check and inspect the packing nut on the chemical selector and metering valves every 200 hours. Keeping the valve packings properly adjusted will prevent leaks and add to the overall life of the valves. PRESSURE REGULATOR Lubricate the o-rings in the pressure regulator every 100 hours. Use only o-ring lubricant (Part #13-003). VACUUM HOSES To ensure maximum hose life, SAPPHIRE SCIENTIFIC recommends that you wash out the hoses with fresh water daily. Microban QGC cleaner as the best product for cleaning and sanitizing the wands and hoses as well as other parts of the system BATTERY! Explosive gases, Dangerous acid! Batteries contain sulfuric acid. To prevent acid burns, avoid contact with skin, eyes and clothing. Batteries also produce explosive hydrogen gases while charging. To prevent fire or explosion, charge batteries only in a well ventilated area. Keep sparks, open flames, as well as any other sources of ignition away from batteries at all times. Remove all jewelry prior to servicing batteries. Keep batteries out of the reach of children. Before disconnecting the negative ( ) ground cable, ensure that all switches are in the OFF position. If ON, a spark could occur at the ground connection terminal, which could cause an explosion if hydrogen gas or gasoline vapors are present. ALWAYS disconnect the negative ( ) terminal first. SAPPHIRE SCIENTIFIC MODEL 370 SS 31

36 SECTION 4 1. If you do not have a maintenance free sealed battery, check the fluid level in the battery at least once a week. If low, fill to the recommended level ONLY with distilled water. DO NOT overfill the battery. Early failure or poor performance will result due to loss of electrolyte. 2. Keep cables, terminals and external surfaces of the battery clean and dry. A buildup of corrosive acid or grime on the external surfaces could cause the battery to self-discharge. 3. Battery terminals should be cleaned every 100 hours to prevent corrosion buildup. Wash the cables, terminals and external surfaces with a mild baking soda and water solution. Rinse thoroughly with fresh water. DO NOT allow baking soda to enter the battery cells, as this will destroy the electrolyte, resulting in battery failure. HIGH PRESSURE SOLUTION HOSES Inspect your high-pressure solution hoses for wear after the first 100 hours. Thereafter, inspect every 25 hours. If the hoses show any signs of damage or impending rupture, replace the hoses.! NEVER attempt to repair high-pressure solution hoses. Repairing high-pressure solution hoses may result in severe burns and serious injury. All high-pressure solution hoses must be rated for 3000 PSI at 250 deg. F. Thermoplastic hoses do not meet this requirement and should not be used. Severe burns and injury may result if the hoses do not meet these requirements. 7. GENERAL SERVICE ADJUSTMENTS!
