PRESSURE WASHER
OPERATOR’S MANUAL
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
Remove bolts from pallet to foot bracket. Install rubber
feet provided as shown in exploded view.
Location:
The location should protect the machine from damag-
ing environmental conditions, such as; wind, rain, and
freezing.
1. This machine should be run on a level surface
where it is not readily influenced by outside sourc-
es such as strong winds, freezing temperatures,
rain, etc. It should be located to allow accessibility
for refilling of fuel, adjustments and maintenance.
Normal precautions should be taken by the op-
erator of the machine to prevent moisture from
reaching the electrical controls.
2. It is recommended that a partition be made be-
tween the wash area and the machine to prevent
water spray from coming in contact with the
machine. Excess moisture reaching any electric
components or electrical controls will reduce ma-
chine life and may cause electrical shorts.
3. During installation of the machine, beware of
poorly ventilated locations or areas where exhaust
fans may cause an insufficient supply of oxygen.
Sufficient 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 a machine in a poorly ventilated area, out-
side fresh air may have to be piped to the burner
and a fan installed to bring air into the machine.
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor
and walls. (Two feet away from walls should be ad-
equate.)
Water Source:
The water source for the pressure washer should be
supplied by a minimum 5/8” I.D. garden hose with a
city water pressure of not less than 30 PSI. If the water
supply is inadequate, or if the garden hose is kinked,
the attached pressure washer will run very rough and
the burner will not fire.
Connection:
See Component Identification.
Venting:
Adding exhaust vent pipe to your oil fired burner is
not recommended because restricted air flow causes
carbon build-up, which affects the operation, and in-
creases maintenance on the coil. If a stack must be
used, refrain from using 90° bends. If the pipe can not
go straight up then use only 45° bends and go to the
next size pipe. The overall pipe length must not exceed
6 feet in length. The burner air adjustment must be
performed after vent pipe is installed. Use a smoke
tester for proper air setting.
