PRESSURE WASHER
OPERATOR’S MANUAL
INSTALLATION INSTRUCTIONS
Getting Started
IMPORTANT: The use of a backow 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
where it is not readily influenced by outside sources
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
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 wand coming in contact with the pressure
washer. Moisture reaching the equipment will reduce the
pressure washer’s life. All installations should comply with
the local codes covering such installations.
Venting
CAUTION: All venting must be in accordance with ap-
plicable federal and state laws, and local ordinances.
Consult local heating contractors.
If the pressure washer is to be used in an enclosed area, a
ue must be installed to vent burner exhaust to the outside
atmosphere. Exhaust gases should not be vented into a
wall, a ceiling, or a concealed space of a building. Be sure
the ue is the same size as the burner exhaust vent on
the pressure washer. See Component Identication 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 sufcient 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 have to be piped to the burner and a fan installed to
bring sufficient air into 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 red pressure washer
must have a draft regulator installed in the ue (available
from most heating contractors). A draft regulator will
permit proper upward flow of exhaust flue gases.
