&OHMJTI t DO NOT stop spraying water for more than two minutes at a time. Pump operates in bypass mode when spray gun trigger is not pressed. When the temperature inside the pump rises too high the thermal relief valve (T) will open and release a gush of T water in an effort to lower the temperature inside the pump. The thermal relief valve will then close. If pump is left in bypass mode for more than two minutes internal components of the pump can be damaged. START-UP PROCEDURE 1. Connect the water hose to the water source. Turn the water source on to remove all air from the hose. When a steady stream of water is present, turn the water source off. 2. Verify the filter screen (U) is in water inlet of pump. The cone side faces out. 3. Connect the cold water source (V) to pump inlet. NOTE: Water source must provide a minimum of 5 gallons per minute at 20 psi (138 kPa). VH U WARNING: To reduce the possibility of contamination always protect against backflow when connected to a potable water system. 4. Connect high-pressure hose (H) to pump outlet. 5. If applying a chemical or cleaning solution, refer to Chemicals and Cleaning Solvents. 6. Turn the water source on. NOTICE: Risk of property damage. Failure to do so could cause damage to the pump. 7. Remove all air from the pump and high pressure hose by depressing trigger until a steady stream of water is present. 8. Plug GFCI (O) into power receptacle. Firmly press and O N release the TEST button (M), then press and release M the RESET button (N). The light on the GFCI should be illuminated. 9. Place the motor ON/OFF switch (K) to the ON Position. 10. Depress trigger on gun to start water flow. WARNING: Risk of unsafe operation. Stand on a stable surface and grip gun/wand firmly with both hands. Expect the gun to kickback K when triggered. 11. Release trigger to stop water flow. DANGER: Risk of injury from spray. Engage the X trigger lock (X) when gun is not in use to prevent accidental spraying. 12. Adjust spray for the task being performed by changing quick connect nozzle. Refer to Spray Wand Nozzles. 9
