3. Attach water source to water inlet located on pump. The water source must be attached with a

good quality standard garden type hose (1/2” minimum is required). Connect male fitting into the

female pump inlet fitting. Make sure that the inlet screen/filter is intact and fitted correctly. Turn

on water source. WATER MUST BE IN SUFFICIENT SUPPLY, AND PRESSURE MUST BE

BETWEEN 20 –60 PSI TO ENSURE PROPER AND SAFE OPERATION. Specific attention

should be given if using a well water supply. Ensure water is flowing from end nozzle with the

trigger gun pulled. Deplete system of all air.

4. Start Gas/Diesel Engine

Refer to instructions in engine manual. MAKE SURE THAT THE ENGINE EXHAUST IS NOT

FACING ANY FLAMMABLE MATERIALS.

5. Burner operation

Be sure water is flowing through water heater coil before turning on BURNER switch. Turn

thermostat to desired temperature. Burner will ignite and remain in operation as long as there is

sufficient water flow to satisfy the pressure switch and temperature control.

IF YOU EXPERIENCE IGNITION FAILURE, DO NOT ATTEMPT TO RESTART

BURNER! EXCESS FUEL AND VAPORS MAY HAVE ACCUMULATED AND THE

CHAMBER MAY BE HOT. THE UNIT MUST COOL DOWN BEFORE RESTART CAN

BE ATTEMPTED.

Warning: Condensation on Coil

When cold water is being pumped through the heater coil and the burner is firing, condensation

may form at times on the coil and drip down into the burner compartment. This can be

particularly noticeable on cold, humid days giving the false appearance of a leaking coil. A

leaking coil or system will be evident if the pump keeps cycling with the trigger released. The

pump head pressure should read ‘0’.

Electrically Operated Burners – These models generate 12V from the gasoline engine and

provide the necessary power for the burner. IF YOU REQUIRE UPGRADES OR

MODIFICATIONS TO YOUR EXISTING ELECTRICAL SYSTEM IN ORDER TO

OPERATE YOUR PRESSURE WASHER, THEY MUST BE PERFORMED BY A LICENSED

ELECTRICIAN AND BE COMPLETED IN ACCORDANCE TO ALL APPLICABLE CODES

IN YOUR AREA OF OPERATION. The power supply must be adequate for your specific unit.

Make sure to verify the data plate for your machine’s specific requirements (i.e. voltage,

amperage, etc.).

6. Pressure adjustment - The pressure regulator (unloader) is located on the pump (see pages

19, 21 & 23 diagrams. It controls the pressure being generated by the pressure washer. This

regulator may be adjusted to the desired pressure by turning the adjustment knob. Turning the

adjustment knob clockwise will increase the pressure. NEVER OPERATE SYSTEM AT A

HIGHER PSI THAN THE MAXIMUM RATING. This machine has been adjusted to operate

at a specific maximum pressure as per the machine specifications. Pressure may be reduced for

lighter use by turning the Pressure Regulator/Unloader counter clockwise. If continuing to turn

the unloader clockwise does not increase the pressure, then this implies the maximum has been

reached for
