Installation
Getting Started
IMPORTANT: Proper initial installation of
equipment will assure more satisfactory perfor-
mance, longer service life, and lower maintenance
cost.
IMPORTANT: The use of backflow preventer on the
water supply hose is recommended and may be
required by local code.
The pressure washer should be run on a level surface
and in a protected area where it is not readily influ-
enced by outside forces such as strong winds, freezing
temperatures, rain, etc. The pressure washer should be
located to assure easy access for filling fluids, adjust-
ment and maintenance. Normal precautions should be
taken by the operator to prevent moisture from
reaching the pressure washer. It is recommended that
a partition be made between the wash area and the
pressure washer to prevent direct spray from the high-
pressure wand from coming in contact with the
pressure washer. Moisture reaching the pressure
washer will reduce its service life. All installations
should comply with the local codes covering such
installations.
IMPORTANT: DO NOT run machine indoors or in an
enclosed area where high ambient temperatures
exist. High ambient temperatures (above 100°
F)
can cause engine oil failure and will greatly reduce
the engine’s performance.
Venting
CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordi-
nances. Consult local heating contractors.
ATTENTION: Toute la ventilation doit être conforme
aux lois fédérales et de l'État ou de la province, et
aux réglementations locales applicables. Consulter
des entrepreneurs en systèmes de chauffage
locaux.
If the pressure washer is to be used in an enclosed
area, a flue must be installed to vent burner and engine
exhaust to the outside atmosphere. Be sure the flue is
the same size as the burner exhaust vent on the
pressure washer lid. Poor draft will cause the pressure
washer to soot and not operate properly. When
selecting the location for installation, beware of poorly
ventilated locations or areas where exhaust fans may
cause an insufficient supply of oxygen. Proper combus-
tion can only be obtained when there is a sufficient
supply of oxygen available for the amount of fuel being
burned. If it is necessary to install the machine in a
poorly ventilated area, outside fresh air will have to be
supplied to the machine. Locate the pressure washer
so that the flue will be as straight as possible and
protrude through the roof at a proper height and
location to provide adequate draft. This oil fired
pressure washer must have a draft regulator installed in
the flue (available from most heating contractors). A
draft regulator will permit proper upward flow of exhaust
flue gases.
