FEATURES INSTALLATION & PREPARATION Features Installation & Preparation ATTIRE Proper attire is essential to your safety. It is advised to utilize whatever means necessary to protect eyes, ears, and skin. Additional safety attire (such as respiratory mask) may be required when using detergent cleaning agents with this washer. SET-UP 1. This unit should only be placed on a level surface to ensure proper lubrication for the water pump while operating. NEVER spray water directly on the unit. 2. Do not use unit in an area: a. with insufficient ventilation. b. where there is evidence of oil or fuel leaks. c. where flammable gas vapors may be present. This unit has multiple ignition sources that could cause an explosion or fire. 3. Do not allow the unit to be exposed to rain, snow or freezing temperatures. If any part of the unit becomes frozen, excessive pressure may build up in the unit which could cause it to burst resulting in possible serious injury to the operator or bystanders. 4. Be certain to block the wheels to prevent the unit from moving while operating. 5. Pump oil level should be checked before each use. Make certain the oil is on the “Full” mark on the dipstick or in the center of the oil sight glass. If the level appears to be low, fill with SAE30W non-detergent pump oil.

PARTS LIST PARTS LIST FLOW CHART GENERAL THEORY OF OPERATION FLOW CHART EMF SYSTEM WATER FLOW: Connect a pressurized water source to the INLET GAR- DEN HOSE CONNECTION (1) and turn on the water supply. The water then travels into the TRIPLEX HIGH PRESSURE PUMP (2) which has an UNLOADER (6) that bypasses the water when the trigger gun is closed. To protect the pump from heated water during this bypass stage, a HEAT DUMP VALVE (5) will open at 140°F/60°C allowing the heated water to escape. The Heat Dump Valve automatically resets when the water cools. The PRESSURE SWITCH (7) controls the fuel supply to the burner. From there, the water will flow into the HEAT EXCHANGER INLET (10) where it is heated when the burner is on. As the water exits the HEAT EXCHANGER OUTLET (11), it enters a safety system which protects the operator from danger. The safety system contains a HIGH TEMPERA- TURE LIMIT SWITCH (12) which senses the water temperature and shuts off the fuel supply to the burner if it gets too hot. If the unloader fails to bypass the water or the burner remains on when the trigger gun is closed, the SAFETY RELIEF (13) will relieve and allow water to exit FLOW CHART EMF SYSTEM safely. EMF SYSTEM The heated water then flows through the HIGH PRESSURE HOSE (14) and to the TRIGGER GUN ASSEMBLY (15) which allows the operator to control the water spray. When the trigger gun is open, the water flows ...
