Place machine in a convenient location providing
ample support, drainage and room for maintenance.
Location:
The location should protect the machine from damaging environmental conditions, such as wind, rain and
freezing.
1. The machine should be run on a level surface
PRESSURE WASHER
where it is not readily influenced by outside sources such as strong winds, freezing temperatures,
rain, etc. The machine should be located considering accessibility for the replacing of components
and the refilling of detergents, adjustments and
maintenance. Normal precautions should be taken
by the operator of the machine to prevent excess
moisture from reaching electrical controls.
OPERATOR’S MANUAL
2. It is recommended that a partition be made between the wash area and the machine to prevent
direct spray from the spray gun from coming in
contact with the machine. Excess moisture will
reduce the machine’s 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, outside fresh air may have to be piped to the burner
and a fan installed to bring the air into the area.
4. Do not locate near any combustible material. Keep
all flammable material at least 20 feet away.
Local code will require certain distances from floor
and walls. (Two feet away should be adequate).
WARNING: Avoid small areas or near exhaust
fans.
Gas Codes:
Confer with local gas company and with proper municipal officials regarding any specific code or regulations governing the installation. The installation must
conform to local codes.
Gas Piping:

Venting:
This machine is to be used indoors and requires
ventilation.
When venting the machine, if the machine is to be in
an enclosed area with a vent pipe, be sure it is the
same size as the stack on the machine. Poor draft will
cause the machine to soot and not operate efficiently.
PRESSURE WASHER
When placing the machine for installation, position the
vent pipe to be as straight as possible and to protrude
through the roof of the building at a proper location and
at sufficient height to eliminate down-draft. Venting of a
gas fired machine shall be installed with a down-draft
diverter located about 3 ft. above machine.

NOTE: If the vent pipe exceeds 10 ft. in length, or
contains more than two elbows, use next size larger
pipe and draft diverter or the burner will not ignite. No
movable vent pipe damper should be used on any
installation.
Figure 3
Draft Diverter:
Install the draft diverter
above the heating coil.
The diverter enhances
the draft through the
burner by severing the
chimney effect created
in sections of vent pipe
positioned below. It also
helps prevent freezing
of the coil due to wind
chill factors.
When in a tightly closed
room without ventilation
openings to the outdoors or other rooms, provisions
shall be made for supplying air for combustion through
special openings, one near the floor and the other
near the ceiling, each to be sized on the basis of one
square inch or more of free area for each 1,000 BTU
input per hour (see Figure 4).
When a room is of unusually tight construction and
has a ventilating fan, which may be used for exhausting air outdoors -or has a vented exhaust — it is
recommended that combustion air be supplied to
the enclosed room through intakes extending to the
outside of the building and terminating in down-turned
fittings. These should be suitably arranged to prevent
obstruction from snow or rain, and include a protecting
10
screen not smaller than 1/4 inch mesh.

The water source for the machine should be supplied
by a 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 machine will run
very rough and the burner will not fire.
Water Connection:
Connect the high pressure hose by pulling the coupler
collar back and then inserting it onto the discharge
nipple. Secure it by pushing the collar forward.
Attach the wand into the spray gun using teflon tape
on the pipe threads to avoid leaks.
Inspection and Testing Gas Piping:
The building structure should not be weakened by
installing the gas piping. The piping should not be
supported by other piping, but should be firmly supported with gas hooks, straps, bands or hangers. Butt
or lap welded pipe should not be run through or in an
air duct or clothes chute.
Before turning gas under pressure into piping, all openings from which gas can escape should be closed.
Immediately after turning on gas, the system should
be checked for leaks. This can be done by watching the
1/2 cubic foot test dial for 5 minutes for any movement
or by soaping each pipe connection and watching for
bubbles. If a leak is found, make the necessary repairs
and repeat the above test.
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any form to locate
gas leaks — use a soap solution.
After the piping and meter have been checked completely, purge the system of air. DO NOT bleed the air
inside an enclosed room.
During pressure testing of the system at test pressures
in excess of 1/2 PSIG, the appliance and its individual
shut-off valve must be disconnected from the gas supply piping system or damage to the gas valve will occur.

98011950-19
WARNING: Some detergents
may be harmful if inhaled or ingested, causing severe nausea,
fainting or poisoning. The harmful elements may cause property
damage or severe injury.
PRESSURE WASHER
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent
solution as required by the manufacturer. Fill a container with pressure washer detergent.
STEP 2: Place siphon tube strainer

Siphon Strainer
STEP 3: Pull trigger to oper-
ate machine. Liquid detergent
is drawn into the machine and
mixed with water. Apply detergent to work area. Do not allow
detergent to dry on surface.
98011950-20
IMPORTANT: You must flush
the detergent siphoning system after each use by
placing the suction tube into a bucket of clean water,
then run the pressure washer for 1-2 minutes.
THERMAL PUMP PROTECTION
If you run your pressure washer for 3-5 minutes without
pressing the trigger on the spray gun, circulating water
in the pump can reach high temperatures. When the
water reaches this temperature, the pump protector
engages and cools the pump by discharging the warm
water onto the ground. This thermal device prevents

internal damage to the pump.
Follow operating instructions.

CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to
be drying, simply wet down surface with fresh water. If
needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may remove
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If no
damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinners,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Select and install desired high pressure nozzle. NOTE: You can also stop
detergent from flowing by removing detergent siphon
tube from bottle.
