Maintenance
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. De-soot coils
monthly. Use an additive if diesel is being used.
2. Check to see that the attached pressure washer
water pump is properly lubricated.
3. Follow Winterizing Procedures to prevent freeze
damage to pump and coils.
4. Always neutralize and flush chemical from system
after use.
5. If water is known to be high in mineral content, use
a water softener on your water system, or de-scale
as needed.
6. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
7. Always use high grade quality cleaning products.
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
Air Adjustments).
10. Never allow water to be sprayed on or near the
motor or burner assembly or any electrical compo-
nent.
11. Delime coils 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 this equipment
clean and dry.
The areas around the washer should be kept clean and
free of combustible materials, gasoline and other
flammable vapors and liquids.
The flow of combustion and 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
whenever the washer must be stored or operated
outdoors under freezing conditions.
During winter months, when temperatures drop below
32°F, protecting your machine against freezing is
necessary. Store the machine in a heated room. If this
is not possible, use compressed air to blow all water
out of the system.
High Limit Thermostat
For safety, each machine is equipped with a high limit
control switch. In the event the temperature of the water
should exceed its operating temperature the high limit
control will turn the burner off until the water cools.
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 preven-
tion for liming conditions is to use high quality cleaning
chemicals. In areas where alkaline water is an extreme
problem, periodic use of Deliming Powder will remove
lime and other deposits before coil becomes plugged.
Deliming Coils
Periodic flushing of coils or optional float tank is
recommended.
Step 1 Fill a container or float tank with 4 gallons of
water, then add 1 lb. of deliming powder. Mix thor-
oughly. Verify mixing ratio on deliming powder package.
Step 2 Remove nozzle from wand assembly and put
spray gun and wand assembly into float tank. Attach a
nylon stocking to the end of the wand to collect debris.
Step 3 Attach a short section (3-5 ft.) of garden hose to
the attached pressure washer to siphon solution from
an elevated container. Turn attached pressure washer
switch on, allowing solution to be pumped through coils
back into the container. Solution should be allowed to
circulate 2-4 hours.
Step 4 After circulating solution flush entire system with
fresh water. Reinstall high pressure nozzle into wand.
