Page 9: Operating Characteristics
OPERATING CHARACTERISTICS MAXIMUM WORKING PRESSURE The water heater coils are designed to operate safely at specific working pressures (see SPECIFICATIONS for the water pressure of your model). Each water heater is equipped with a safety pressure relief valve (unloader) which prevents operation above this pressure. If the high pressure system requires a lower relieving pressure for pump and motor protection, then the unloader/bypass valve on the pumping unit should be adjusted to desired pressure rating. -
Page 10: Installation
INSTALLATION These water heaters are certified for installation on non-combustible floors. 2. Electrically Operated Burners – Some models generate 12V from the gasoline engine and provide the necessary power for the burner. Others utilize a 120v connection which must be grounded. -
Page 11: Winter Pump/ Coil Protection
TO CHECK HEATER COILS FOR LEAKS Start pumping unit and allow it to run for a few minutes with burner turned off. Check burner compartment with a trouble light or flash light. If no leaks are visible, this will confirm that occasional water dripping from the coil is due to condensation of the flue gases, when burner is firing. - Page 12 If the burner floods with oil: run machine with heat on until all excess oil is burned off (this can take up to a couple of hours). If excess oil is not properly dealt with, the ceramic casing can absorb excess oil, causing a fire hazard.

Page 17: Service Manual
SERVICE MANUAL This manual is intended for technical personnel to assist in the diagnosis and repair of issues with pressure washers. This manual is not intended for use by non-technical personnel. It is advised to always refer to competent technical personnel when repairs are advised to avoid equipment damage or potential personnel injury. - Page 18 FLUID SYSTEM DIAGNOSTICS - Flow and Pressure PROBLEM POSSIBLE CAUSE SOLUTION No power Make sure pump is operating. Check drive belts and couplings, make necessary adjustments. Trigger gun valve Check trigger gun, repair or replace. No water source Ensure water supply is not restricted and hoses are in good repair and not kinked. No Flow Clogged spray nozzle Check spray nozzle, repair or replace.
- Page 19 PROBLEM POSSIBLE CAUSE SOLUTION Nozzle must be properly sized for the rated flow and pressure. Reset unloader or pressure relief Small spray nozzle if nozzle size is changed. Check the pressure gauge using a properly calibrated pressure gauge on quick connects at the Excessive pressure Faulty pressure gauge equipment outlet.
- Page 20 FLUID SYSTEM DIAGNOSTICS - Unloader PROBLEM POSSIBLE CAUSE SOLUTION Isolate the flow problem. If it occurs before the unloader discharge point, check the piston Very low or no flow Unloader stuck in bypass assembly to see if it is fouled or stuck in bypass mode. Debris in unloader Take bottom nut off unloader, identify ball, spring and seat.
- Page 21 Unloader adjusted too low If the unloader is diverting flow to bypass it may be adjusted too low, readjust as necessary. Unloader (pressure) produces low flow and Spray nozzle to large Ensure the proper nozzle is installed on system. normal pressure Internal nozzle erosion The number of hours of usage can give you a clue to the extent of the ware.
- Page 22 FLUID SYSTEM DIAGNOSTICS - Leaking ANY LEAKS SHOULD BE REPAIRED ASAP TO PREVENT DAMAGE TO THE SYSTEM. PROBLEM POSSIBLE CAUSE SOLUTION From inlet Garden hose washer Ensure the washer is present and in good condition. From low pressure (inlet) Loose clamps or connections Low pressure line should be properly sealed on barb and tightly clamped.
- Page 23 FLUID SYSTEM DIAGNOSTICS - Trigger Gun/Spray Nozzle PROBLEM POSSIBLE CAUSE SOLUTION If water flows through discharge hose without gun, check trigger gun valve piston rod and Broken piston rod in trigger gun replace if necessary. No nozzle flow from nozzle when trigger depressed.
- Page 24 BOILER SYSTEM DIAGNOSTICS - Oil Burner Will Not Fire PROBLEM POSSIBLE CAUSE SOLUTION Not reaching rated pressure Not activating boiler controls Correct the fluid problem first - See fluid systems diagnostics flow Thermostat on low setting Thermostat set too low Set thermostat to an output temperature requiring heating.
- Page 25 PROBLEM POSSIBLE CAUSE SOLUTION Remove the solenoid cover and place blade of an insulated screwdriver in the coil with the Steady fuel flow at bleed Solenoid valve not energizing system operating in hot water mode. A good working solenoid will hold the screwdriver in the valve but none in solenoid.
- Page 26 BOILER SYSTEM DIAGNOSTICS Water Output Temperature Too Low - Oil or Gas Fired PROBLEM POSSIBLE CAUSE SOLUTION Burner firing normally but with outlet temp lower than Thermostat set too low Set the thermostat to proper output temperature. rated If inlet water is freezing to the touch, the boiler may not be able to reach desired temperature Inlet water too cold increase.
- Page 27 BOILER SYSTEM DIAGNOSTICS - Pressure Switch PROBLEM POSSIBLE CAUSE SOLUTION A multimeter can indicate if the proper voltage flows through the boiler side of the switch. If not Switch activates when Control not flowing through switch the switch may not need replaced. pressure is reached but boiler not firing Switch improperly wired...
