PREVENTATIVE MAINTENANCE
1.Use clean fuel - kerosene, No. 1 home heating fuel or diesel. Clean or replace fuel filter every 100 hours of operation. Avoid water contaminated fuel as it will seize up the fuel pump.
2.Check to see that the attached pressure washer water pump is properly lubricated.
3.Follow winterizing instructions to prevent freeze damage to pump and coils.
4.Always neutralize and flush detergent from system after use.
5.If water is known to be high in mineral content, use a water softener on your water system, or
6.Do not allow acidic, caustic or abrasive fluids to be pumped through system.
7.Always use high grade quality cleaning prod- ucts.
8.Never run attached pressure washer pump dry for extended periods of time.
9.If machine is operated with smoky or eye burning exhaust, coils will soot up, not letting water reach maximum operating temperature. (See section on Maintenance and Service).
10.Never allow water to be sprayed on or near the motor or burner assembly or any electrical com- ponent.
11.Delime coils as per instructions.
It is advisable, periodically, to visually inspect the burner. Check air inlet to make sure it is not clogged or blocked. Wipe off any oil spills and keep equipment clean and dry.
The areas around the machine should be kept clean and free of combustible materials, gasoline and other flammable vapors and liquids.
The flow of ventilating air to the burner must not be blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Winterizing Procedure:
Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures when- ever the washer must be stored or operated outdoors under freezing conditions.
During winter months, when temperatures drop be- low 32°F, protecting your machine against freezing is necessary. Store the machine in a heated room. If this is not possible use compressed air on the short hose end. By injecting compressed air, all water will be blown out of the system. Run
Rupture Disk:
For safety, each machine is equipped with a rupture disk. In the event the pressure of the water should ex- ceed 8000 PSI, the rupture disk will release pressure and water on to the ground.
When the disk ruptures, it will need to be replaced.
NOTE: Turn burner switch off. Then open spray gun to cool heating coil or rupture disk will burst over time.
Adjustable Thermostat:
The adjustable thermostat can be set between 100°F to 225°F (37.8° to 108°C). The temperature is depen- dent on water flow and ambient water temperature.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate rapidly inside the coil pipes. This growth is increased by the extreme heat build up in the coil. The best prevention for liming conditions is to use high quality cleaning detergents. In areas where alkaline water is an extreme problem, periodic use of Deliming Pow- der will remove lime and other deposits before coil becomes plugged.
Deliming Coils With A Pressure Washer:
Periodic flushing of coils or optional float tank is rec- ommended.
Step 1 Fill a 5 gallon bucket with 4 gallons of water, then add 1 lb. of deliming powder. Mix thor- oughly.
Step 2 Remove the high pressure nozzle from the pressure wand and put the wand into the bucket. Secure the trigger on the spray gun in the open position.
Step 3 Attach a short section
Step 4 After circulating solution flush entire system with fresh water.
Removal of Soot In Heating Coil:
In the heating process fuel residue, in the form of soot deposits, may develop between the heating coil pipes and block air flow which affects burner combustion. When soot has been detected on visual observation, the soot on the coil must be cleaned off.
