22. When making repairs disconnect from electrical
source.

23. Turn burner off and open spray gun to allow water to
flow and cool coil to 100°F before turning machine
off.

24. Before disconnecting high pressure hose from
hot water outlet, turn off burner to allow water to cool
to 100°F, then turn off pump motor and water supply
and operate spray gun to relieve back pressure in
hose. This will prevent coil damage from thermal ex­pansion.

CAUTION: This machine produces hot water and
must have insulated components attached to pro­tect the operator.

INSTALLATION

Place machine in a convenient location providing ample
support, draining and room for maintenance.

This machine is intended for indoor use. Machine
must be stored indoors when not in use.

Location:

The location should protect the machine from damag­ing 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 sources 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 operator of the
machine to prevent moisture from reaching the
electrical controls.

2. It is recommended that a partition be made between
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 machine 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 air into the machine.

Avoid small locations or areas near exhaust fans.

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 adequate.)

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:

Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon tape
to avoid water leaks. (See Component Identification).

Venting:

Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes car­bon buildup, which affects the operation, and increases
maintenance on the coil. If a stack must be used, refrain
form 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.

STARTING AND OPERATING

4. Connect high pressure hose to discharge nipple by
sliding quick coupler collar back. (If detergent is to
be applied, insert a detergent injector as shown in
Component Identification).

5. Insert quick coupler onto discharge nipple and se­cure by pushing quick coupler collar forward.

6. Securely attach the desired high pressure nozzle into
wand coupler as described in steps 4 and 5.

7. Connect the power cord into the proper electrical
outlet, then push in the GFCI reset button (Refer to
serial plate for information.)

8. Grip spray gun handle securely and pull trigger. Then
turn variable pressure control handle counterclock­wise.

9. Turn switch to pump position. When a steady stream
of water flows from the spray gun and wand, the
machine is ready for cold water cleaning by turning
the variable pressure control handle clockwise to
raise the pressure.

10. For hot water washing, turn the switch to the burner
position. (The burner will light automatically when
the trigger on the spray gun is pulled.)

To Stop:

1. If using the detergent injector, place the suction line
in a bucket of water allowing detergent to be flushed
from system.

2. Turn STP burner switch off and continue spraying
water, allowing the water to cool.

3. After water has cooled to less than 100°F, turn the
attached pressure washer off.

4. Turn garden hose water off. Open the spray gun to
relieve remaining pressure.

5. Protect from freezing.

HOW TO USE THE
DETERGENT INJECTOR

WARNING

SOME DETERGENTS
MAY BE HARMFUL IF

INHALED OR

INGESTED.

1. Pull injector quick coupler collar back and secure on
discharge nipple. Injector valve body arrow should
point in direction of flow.

2. Connect high pressure hose to injector nipple se­curing quick coupler.

3. Start machine as outlined in Operating Instructions.

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.

The machine can siphon and mix de­tergents with the use of Shark's de­tergent injector kit.

4. Place detergent pick-up tube into container of deter­gent solution.

5. Turn pressure control handle counterclockwise on
the variable pressure wand. This lowers the pres­sure by directing the water flow through the soap
nozzle and allows the detergent injector to siphon
soap.

6. Open trigger spray gun. Water detergent ratio is
approximately 15 to 1.

7. When you finish washing, rinse by simply turning
the variable pressure wand control handle clockwise
to increase pressure.

NOTE: The detergent injector will not siphon with
water flowing through the high pressure nozzle at
the end of the wand.

8. For clean up, place detergent pick-up tube into con­tainer of clear water and follow steps 5 and 8 to pre­vent detergent deposits from damaging the injector.
