Unloader Valve
WARNING: The unloader valve on this pressure
washer has been factory set and sealed and is a field
nonadjustable part. Tampering with the factory setting
may cause personal injury and/or property damage,
and will void the manufacturer warranty.
Burner Fuel Filter
Drain any water which has accumulated in fuel filter and
clean or replace element as needed.
Heating Coil
Coil Descaling:
In hard water areas, scale buildup within
the heating coil will occur. Scale deposits will decrease
the water temperature rise and may eventually clog the
heating coil. Contact your local service center when
descaling is needed.
Coil Desooting:
Poor grades of fuel oil or inadequate
combustion air will cause heavy soot buildup on the
outside surface of the heating coil. These deposits will
insulate the coil. This will restrict the air flow through the
coil, further aggravating the soot buildup. Contact your
local service center when desooting is needed.
