9 Getting Started IMPORTANT: Proper initial installation of equipment will assure more satisfactory performance, longer service life, and lower maintenance cost. IMPORTANT: The use of a backflow preventer on the water supply hose is recommended and may be required by local code. The pressure washer should be run on a level surface and in a protected area where it is not readily influenced by outside forces such as strong winds, freezing temperatures, rain, etc. The pressure washer should be located to assure easy access for filling of fluids, adjustments and maintenance. Normal precautions should be taken by the operator to prevent moisture from reaching the pressure washer. It is recommended that a partition be made between the wash area and the pressure washer to prevent direct spray from the wand from coming in contact with the pressure washer. Moisture reaching the equipment will reduce the pressure washer s service life. All installations must comply with the local codes covering such installations. Electrical WARNING: Make sure all switches and controls are in the OFF position prior to connecting electrical supply. WARNING: DO NOT stand in water while connecting and disconnecting electrical supply. IMPORTANT: Consult local building codes for exact electrical requirements. Licensed contractors may be required. Power In Figure 5 - Wiring Connections INSTALLATION INSTRUCTIONS The 5700 Series is designed for connection to an overload protected grounded circuit. It is recommended this circuit be protected by a UL approved ground fault circuit interrupter (GFCI). An electrical disconnect must be provided in this circuit. All wiring must be of proper voltage and amperage rating and conform to applicable codes. Refer to Figure 5 for wiring connections. A hole has been provided in the control box for attachment of 1 inch electrical conduit. For proper operation the motor rotation is to be counterclockwise as viewed looking towards the rear of the motor (opposite pump attachment). If the rotation is incorrect, interchange any two of the power supply connections to reverse rotation. Venting DANGER: DO NOT run machine indoors or in an enclosed area without proper ventilation, as exhaust fumes may be hazardous to your health. DANGER: DO NOT operate machine in areas where flammable vapors (gasoline, solvents, etc.) may be present, as this machine may ignite the vapors. CAUTION: All venting must be in accordance with applicable federal and state laws, and local ordinances. This machine is not to be connected to a type B gas vent. Consult local heating contractors. If the pressure washer is to be used in an enclosed area, a flue must be installed to vent burner exhaust to the outside atmosphere. Be sure the flue is the same size as the burner exhaust vent on the pressure washer lid. Poor draft will cause the pressure washer to soot and not operate properly. When selecting the location for installation, beware of poorly ventilated locations or areas where exhaust fans may cause an insufficient supply of oxygen. Proper combustion can only be obtained when there is a sufficient supply of oxygen available for the amount of fuel being burned. If it is necessary to install the machine in a poorly ventilated area, outside fresh air may have to be piped to the burner and a fan installed to bring sufficient air into the machine. Locate the pressure washer so that the flue will be as straight as possible and protrude through the roof at a proper height and location to provide adequate draft. This oil fired pressure washer must have a draft regulator installed in the flue (available from most heating contractors). A draft regulator will permit proper upward flow of exhaust flue gases. Oil Burner Burner Air Adjustment: The oil burner is preset and performance tested at the factory (elevation 500 feet). A onetime initial correction of the burner for your location will pay off in economy, performance, and extended service life. To adjust, start machine and turn burner ON (refer to Operation for details). Loosen locking screw (refer to Figure 6) and close air band until black smoke appears from burner exhaust vent. Note air band position. Next, PRESSURE WASHER OPERATOR S MANUAL 9

10 OPERATOR S MANUAL PRESSURE WASHER slowly open the air band until white smoke just starts to appear. Turn air band halfway back to the black smoke position previously noted. Tighten locking screw. Air Band Air Adjustment Screw Figure 6 - Burner Adjustment CAUTION: If white smoke appears from burner exhaust vent during start-up or operation, discontinue use and readjust air bands. NOTE: If a flue is installed, have a professional serviceman adjust your burner for a #1 or #2 smoke spot on the Bacharach scale. For additional burner information, refer to Oil Burner Manual provided with this pressure washer. Gas Burner CAUTION: Have a qualified gas serviceman install and service your equipment. WARNING: Gas line supply pressure must not exceed 14 water column inches (.50 PSI). INSTALLATION INSTRUCTIONS Fuel Pump Pressure Adjustment Screw Natural Gas Fuel Have a qualified gas serviceman install the natural gas fuel supply line to the machine. See Figure 7 for location of gas inlet. Gas Valve Inlet View Outlet View Figure 7 - Gas Valve and Regulator Side View The ideal incoming gas pressure is 11 w.c.i. (water column inches) minimum 6 w.c.i., maximum 14 w.c.i. or 1/2 psig. The correct operating manifold pressure for natural gas is 3.5 w.c.i. The operating manifold pressure for propane gas is 11 w.c.i. The gas valve pressure regulator can be adjusted between 3 and 4 w.c.i. natural gas or 6 and 11 w.c.i. for propane. The gas pressure coming out of the regulator and going to the burner ring has been factory set. You should not readjust the burner ring gas pressure. If you replace your gas valve, you will need to adjust the new valve. Refer to your machine s specification plate for the correct pressure setting. Follow the installation and adjustment instructions provided with your replacement valve. IMPORTANT: Gas line must be provided with a shut off valve. IMPORTANT: The gas supply must be able to supply a minimum of 525,000 BTU/HR at the machines rated manifold pressure. Consult building codes for installation requirements. For proper and safe machine operation, we recommend that a licensed contractor be consulted for machine installation. 10

11 Before Starting 1. Read all manuals provided with this pressure washer. Become familiar with location and function of all operating and safety controls. 2. Check pump oil level. WARNING: Check hoses, fittings, wand, trigger gun and fuel connections daily for signs of wear, cracks and looseness, and replace as required. 3. Connect water supply hose to the garden hose connector located on the float tank. The water faucet and supply hose must be capable of providing a minimum of 8.0 gallons per minute (GPM). 4. Fill oil burner fuel tank. Use kerosene, #1 grade home heating oil, #1 or #2 diesel fuel. DO NOT USE GASO- LINE, CRANKCASE OIL DRAININGS, OR WASTE OIL. 5. If detergents are to be used, only use detergents intended for pressure washers. Follow instructions on the detergent container. IMPORTANT: Before installing nozzle on initial startup, turn on the water supply and pump switch and allow water to run from the end of the wand until clear to prevent the nozzle from clogging. IMPORTANT: If the pressure washer has not been used for an extended period of time, remove the nozzle from the end of the wand and turn on water supply and pump switch. Allow water to run from the end of the wand until clear. 6. Install the proper pressure nozzle on end of wand for your cleaning needs, refer to Figure 8. Manual Trigger Lock OPERATION INSTRUCTIONS Pressure Nozzle To Start DANGER: DO NOT point wand or trigger gun at yourself or at any person. Bodily injury may result from water under high pressure. WARNING: Wear eye, ear, hand, foot and skin protection at all times while operating pressure washer. IMPORTANT: The water must be turned on before starting. Running the pump dry will cause damage and void warranty.

12 OPERATOR S MANUAL PRESSURE WASHER GENERAL CLEANING TECHNIQUES & STORAGE CLEANING TECHNIQUES Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and apply to surface at low pressure (for best results, limit your work area to sections approximately 6 feet square and always apply detergent from bottom to top). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water. If needed, use brush to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface. Use overlapping strokes as you clean and rinse any surface. For best surface cleaning action spray at a slight angle. Recommendations: Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results. If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface. Keep the spray nozzle a safe distance from the surface you plan to clean. High pressure wash a small area, then check the surface for damage. If no damage is found, continue to pressure washing. CAUTION - Never use: Bleach, chlorine products and other corrosive chemicals Liquids containing solvents (i.e., paint thinner, gasoline, oils) Tri-sodium phosphate products Ammonia products Acid-based products These chemicals will harm the machine and will damage the surface being cleaned. RINSING It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Select and install desired high pressure nozzle. NOTE: You can also stop detergent from flowing by removing detergent siphon tube from bottle. STORAGE DANGER: DO NOT store flammable liquids (gasoline, diesel fuel, solvents, etc.) near pressure washer, or in non-ventilated areas. Protect from freezing by storing in a heated area, or by flushing the system with antifreeze (use an automotive engine antifreeze or windshield washer solvent to antifreeze). To flush the system fill the float tank with antifreeze and remove pressure nozzle from wand. Start the machine and allow it to run until antifreeze flows from the end of the wand. Place end of wand into float tank and circulate the antifreeze through system for several minutes. Squeeze and release the trigger of the trigger gun several times to antifreeze the unloader system. Also draw antifreeze through the detergent inlet line to antifreeze the detergent system. For added protection after antifreezing, disconnect the pressure hose from machine and remove the coil drain plug (refer to Figure 12 Item 15 for location). After coil has drained, replace pressure hose and coil drain plug. If the pressure washer is not to be used for an extended length of time, it is recommended that the system be flushed with antifreeze for rust protection. 12

13 WARNING: Unauthorized machine modification or use of non-approved replacement parts may cause personal injury and/or property damage and will void the manufacturer warranty. Pump Lubrication: To lubricate pump, use 30W non-detergent oil for pump crankcase. Crankcase must be filled to center of sight glass window found on the rear of the pump, refer to Figure 9. During the break-in-period, make sure the oil is changed after the first 25 hours of operation. After that, replace oil every 3 months or 300 hours of operation, whichever comes first. Sight Glass Figure 9 - Pump Lubrication Proper Pump Care: DO NOT pump acids. DO NOT allow pump to run dry. Winterize if storing in freezing temperatures, refer to Storage for details. Use a water softener on the water system if known to be high in mineral content. Use only high quality detergents and follow manufacturer s mix recommendations. Flush the system with clear water immediately after using detergent solutions. Clean filter screen on detergent inlet line periodically. Flush the pressure washer system with antifreeze if storing for an extended period of time, refer to Storage to details. Pump Motor Oil Fill Inspect the pump motor at regular intervals. The exterior of the motor should be kept free of dirt, oil, grease, water, etc. Keep all ventilation openings free from debris. If the motor is equipped with grease fittings, lubricate the motor after every 1000 hours of operation with Chevron SRI #2 lubricant or equivalent. If the motor is not equipped with grease fittings, the pump motor bearings are permanently lubricated and will not require any additional lubrication. MAINTENANCE Oil Burner Refer to Oil Burner Manual provided with this pressure washer for recommended maintenance. Relief Valve WARNING: The relief valve on this pressure washer has been factory set and sealed and is a field nonadjustable part. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturer warranty. Unloader Valve WARNING: The unloader valve on this pressure washer has been factory set and sealed and is a field nonadjustable part. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturer warranty. Burner Fuel Filter (Oil fired models only) Drain any water which has accumulated in fuel filter and clean or replace filter element as needed. Heating Coil Coil Descaling: In hard water areas, scale buildup within the heating coil will occur. Scale deposits will decrease the water temperature rise and may eventually clog the heating coil. Contact your local service center when descaling is needed. Coil Desooting: Poor grades of fuel oil or inadequate combustion air will cause heavy soot buildup on the outside surface of the heating coil. These deposits will insulate the coil. This will restrict the air flow through the coil, further aggravating the soot buildup. Contact your local service center when desooting is needed. PRESSURE WASHER OPERATOR S MANUAL 13
