Place machine in a convenient location providing ample support, drainage and room for maintenance (see page 8). Gas Piping: Figure 1: DRIP LEG 1/4" Test Port (6" - 14 W.C. or 1/2" PSIG) Location: The location should protect the machine from damaging environmental conditions, such as wind, rain and freezing. 2. It is recommended that a partition be made between the wash area and the machine to prevent direct spray from the spray gun from coming in contact with the machine.
PRESSURE WASHER OPERATOR’S MANUAL INSTALLATION The following pipe and stack sizes are just recommendations. Always consult a local plumber and venting contractor for local codes and regulations during installation. The following tables are maximum capacity of final stage pipe in thousands of Btu/hr of commercial propane From first stage regulator (at tank) to second stage regulator The chart below is based on incoming gas pressure of 10 PSI and a pressure drop of 1 PSI.
Venting: This machine is to be used indoors and requires ventilation.
PRESSURE WASHER OPERATOR’S MANUAL INSTALLATION Before turning gas under pressure into piping, all openings from which gas can escape should be closed. Immediately after turning on gas, the system should be checked for leaks. This can be done by watching the 1/2 cubic foot test dial for 5 minutes for any movement or by soaping each pipe connection and watching for bubbles. If a leak is found, make the necessary repairs and repeat the above test.
Pressure Nozzle Pressure Nozzle Spray Gun Safety Latch Wand Coupler Wand Collar High Pressure Hose STEP 2: Pull the spring-loaded collar of the wand coupler back to insert your choice of pressure nozzle. CAUTION: Never replace nozzles without engaging the safety latch on the spray gun trigger. Cold Water Source Garden Hose STEP 5: Connect garden hose to the cold water source. STEP 4: Connect the high pressure hose to the pump discharge fitting. Push coupler collar forward until secure.
PRESSURE WASHER OPERATOR’S MANUAL OPERATING INSTRUCTIONS Cold Water Source Garden Hose STEP 1: Review installation instructions prior to connecting garden hose to the cold water source and turn water on completely. Never use hot water. STEP 2: Trigger the spray gun to eliminate trapped air then wait for a steady flow of water to emerge from the spray nozzle.
WARNING WARNING: Some detergents may be harmful if inhaled or ingested, causing severe nausea, fainting or poisoning. The harmful elements may cause property damage or severe injury. STEP 2: Place siphon tube strainer into detergent container open detergent valve. Place the filter end of detergent suction tube into the detergent container. Detergent Valve Siphon Strainer STEP 3: Pull trigger to operate machine. Liquid detergent is drawn into the machine and mixed with water.
PRESSURE WASHER OPERATOR’S MANUAL SHUTTING DOWN AND CLEAN-UP Pump Switch Burner Switch STEP 2: Turn/push burner switch to "OFF" position. Open spray gun allowing water to cool. Then turn/push pump switch to “OFF” position. STEP 1: Remove detergent suction tube from container and insert into one gallon of fresh clean water. Pull trigger on spray gun and siphon water for one minute. Safety Latch STEP 3: Turn off water supply. STEP 4: Press trigger to release water pressure.

Troubleshooting Guide PRESSURE WASHER TROUBLESHOOTING PROBLEM POSSIBLE CAUSE SOLUTION NO SPARK - NO PILOT GAS No main power Restore power. SPARK - BUT NO PILOT LIGHT Faulty limit switch Test/replace. Faulty wiring Test wiring. No gas supplied to pilot valve Check for availability of gas. Manual valves in "OFF" position Turn manual valve and gas cock to full "ON". Check pilot key adjustment. Faulty pilot valve Test gas valve. Faulty wiring Test wiring.
PROBLEM POSSIBLE CAUSE SOLUTION WATER TEMPERATURE TOO HOT Incoming water to machine warm or hot Lower incoming water temperature. Gas pressure too high See page 10 for specifications for proper gas pressure. Detergent line sucking air Tighten all clamps. Check detergent lines for holes. PRESENCE OF WATER IN OIL WATER DRIPPING FROM UNDER PUMP DETERGENT NOT DRAWING PUMP RUNNING NORMALLY BUT PRESSURE LOW ON INSTALLATION FLUCTUATING PRESSURE PUMP NOISY Defective high limit switch Replace.
Troubleshooting Guide PRESSURE WASHER MAINTENANCE & SERVICE Spray Nozzles: Pumps: Each machine is equipped with one or more spray nozzles, depending on the model. Different spray nozzles are calibrated for each machine, depending on the flow and pressure of that particular model. Spray nozzles vary in bore size and angle of spray. Popular spray angles are 0°, 15°, 25°, 40°. When ordering, please specify size and angle of nozzle. Nozzle size for each machine is located on the serial plate.
Gas Valve Regulator Adjustment: Gas Pressure Requirements: (See Fig. 5) Adjustment of the built-in regulator isn’t normally necessary, since it is preset at the factory. However, field adjustment may be accomplished as follows: All propane fired machines operate on gas phase only. They are designed to operate at a pressure of 11 w.c.i. (between 1/3 and 1/2 of one PSI), and are often operated at even higher pressures when extra heat is needed. 1. Attach manometer at both inlet and outlet pressure ports.
Troubleshooting Guide PRESSURE WASHER MAINTENANCE & SERVICE 2. TO CLEAN BURNER JETS: Select proper size drill for type of gas involved. Use vise to hold drill and to ream out each jet orifice. If the water heater will be exposed to freezing weather, an antifreeze solution should be circulated through the coils by whatever means are available for the particular system the water heater is used on.
b. Shorten switch lead wires and/or replace with heavier gauge wire. c. Cycle switch rapidly to clean contacts. D. Automatic Pilot Dropout Check 1. Hold gas cock dial depressed in pilot position until maximum output is observed. Then extinguish pilot and observe meter. 2. Dropout of automatic pilot magnet (sound should be audible) should occur between 120 millivolts and 30 millivolts. If dropout occurs outside these limits, change the automatic pilot magnet assembly.
Troubleshooting Guide PREVENTATIVE MAINTENANCE This pressure washer was produced with the best available materials and quality craftsmanship. However, you as the owner have certain responsibilities for the correct care of the equipment. Attention to regular preventative maintenance procedures will assist in preserving the performance of your equipment. Contact your dealer for maintenance. Regular preventative maintenance will add many hours to the life of your pressure washer.
