INSTALLATION
Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer service life, and lower maintenance cost.
IMPORTANT: The use of a 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 influenced
by outside forces such as strong winds, freezing
temperatures, rain, etc. The pressure washer should be
located to assure easy access for filling of fluids,
adjustments and maintenance. Normal precautions should
be taken by the operator to pre vent moisture from reaching
the pressure washer. It is recommended that a par tition
DANGER: Do not operate machine in areas where
flammable vapors (gasoline, solvents, etc.) may be
present, as this machine may ignite the vapors.
CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordinances. Consult local heating contractors.
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. See Figure 1 for location. 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
combustion 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 may ha ve to be piped to
the burner and a fan installed to bring sufficient air into
the machine. Locate the pressure w asher 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.
In addition, the pressure washer should nev er be operated
in an enclosed area where high ambient temperatures
exist. High ambient temperatures (above 100
cause engine oil failure and will greatly reduce the engine’ s
performance.
