Drain Burner's Fuel Filter/Water Separator
Drain water from burner's filter bowl as needed. Replace

Important: Always empty the burner's fuel tank
•
before removing the filter bowl.
Check the filter bowl after each use of burner.
•
Drain accumulated water via water drain at the
bottom of the bowl.

•
empty the burner's fuel tank to remove the filter
bowl and inspect the fuel filter/water separator.
Descale Heating Coil
If pressure washer is used where the water source
contains a high mineral content, or is considered "Hard
Water", scale can build up inside the heating coil tubing.
Scale deposits will decrease the performance of
pressure washer by reducing both water flow and water
pressure. The use of a water softener and an additional
strainer may be needed in areas that have high mineral
content in the water supply. More frequent descaling
may be required if higher temperatures or steam mode
is used regularly. Descale the coil tubing more
frequently if you detect a decrease in pressure or
temperature.
CAUTION: De-scaling burn hazard
Do not run the burner while de-scaling.
