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.

PREVENTATIVE MAINTENANCE
1. Use clean fuel - kerosene, No. 1 home hearing fuel or
diesel fuel. Clean or replace fuel filter every 100 hours
of operation. Avoid water contaminated fuel as it will
seize up the fuel pump. De-soot coils monthly. Use
an additive if diesel is being used.
2. Check to see that the attached pressure washer water
pump is properly lubricated.
3. Follow Winterizing Procedures to prevent freeze damage to pump coils.
4. Always neutralize and flush detergent from system
after use.
5. If water is known to be high in mineral content, use a
water softener in your water system or de-scale as
needed.
6. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
7. Always use high grade quality cleaning products.
8. Never run pump dry for extended periods of time.
9. If machine is operated with smoking or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Air Adjustments.)
10. Never allow water to be sprayed on or near engine
or burner assembly or any electrical component.
11. Periodically delime coils per instructions.
It is advisable, periodically, to visually inspect the burner.
Check air inlet to make sure it is not clogged or blocked.
Wipe off any oil spills and keep this equipment clean and
dry.
The areas around the Shark washer should be kept clean
and free of combustible materials, gasoline and other flammable vapors and liquids.

water into a 5 gallon bucket. Place a short section of
garden hose into bucket and connect it to machine. Elevate
bucket and turn pump on to siphon anti-freeze through
machine. If compressed air is available, an air fitting can be
screwed into the inlet connector and, by injecting compressed air, all water will be blown out of system.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event that the temperature of the
water should exceed its operating temperature, the high
limit control will turn the burner off until the water cools.
Pumps:
Use only SAE 30W non-detergent oil. Change oil after
the first 50 hours of use. Thereafter, change the oil every
three months or at 500 hour intervals. Oil level should be
checked by using the dipstick found on top of the pump
or the red dot visible through the oil gauge window. Oil
should be maintained at that level.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the coil pipes. This growth is increased by
the extreme heat build up in the coil. The best prevention
for liming conditions is to use high quality cleaning detergents. In areas where alkaline water is an extreme
problem, periodic use of Shark Deliming Powder (part
#9-028008) will remove lime and other deposits before
coil becomes plugged. (See Deliming Instructions for use
of Shark Deliming Powder.)
Deliming Coils:
Unloader valves are preset and tested at the factory before shipping. Occasional adjustment of the unloader may
be necessary to maintain correct pressure. Call your
local dealer for assistance.
Periodic flushing of coils is recommended.
1. Fill a container or optional float tank with 4 gallons of
water, then add 1 lb. of deliming powder. Mix thoroughly.
2. Remove wand assembly from spray gun and put spray
gun into container. Secure the trigger on the spray
gun into the open position.
3. Attach a short section (3-5 ft.) of garden hose to
machine to siphon solution from an elevated container. Turn pump switch on, allowing solution to be
pumped through coils back into the container. Solution should be allowed to circulate 2-4 hours.
4. After circulating solution flush entire system with
fresh water. Reinstall wand assembly to spray gun.
Winterizing Procedure:
Removal of Soot in Heating Coil:
Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures whenever
washer must be stored or operated outdoors under freezing conditions. During winter months, when temperatures
drop below 32°F, protecting your machine against freezing is necessary. Store machine in a heated room. If this
is not possible then mix a 50/50 solution of anti-freeze/
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipe and
block air flow which will affect burner combustion. When
soot has been detected on visual observation, the soot
on the coil must be washed off after coil has been removed using the following steps:
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
MAINTENANCE AND SERVICE

1. Remove the tank head assembly by lifting the tank
head off.
2. Remove the two pipe nipples and associated fittings.
3. Lift the coil out of the outer wrap.
CAUTION: the coil weighs about 80 lbs. Use proper
lifting techniques.
4. Clean, repair and replace the coil by reversing the
above steps.
Coil Reinstallation
Reinstall by reversing the above steps 4 through 1.
Rupture Disk
If pressure from pump or thermal expansion should exceed safe limits, the rupture disk will burst, allowing high
pressure to be discharged through hose to ground. When
the disk ruptures, it will need to be replaced.
Fuel:
Use clean fuel oil that is not contaminated with water and
debris. Replace fuel filter and drain tank every 100 hours
of operation. Use Kerosene No. 1 or No. 2 Heating Fuel
(ASTM D306) or diesel only. NEVER use gasoline in your
burner tank. Gasoline is more combustible than fuel oil
and could result in a serious explosion. NEVER use crankcase or waste oil in your burner. Fuel unit malfunction
could result from contamination.
Ignition Circuit:
Periodically inspect wires, spring contact and electrodes
for condition, security and proper spacing. For transformer
test (CAUTION 10,000 VOLTS) use defect free insulated
screwdriver and keep fingers off blade! Lay blade across
one contact: OK if arc will span 1/2" between end of blade
and other contact (see following illustration).
Electrode Setting: Beckett
5/32" Gap
Keep the tip free of surface deposits by wiping it with a
clean, solvent-saturated cloth, being careful not to plug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
Fuel Control System:
The STP utilizes a fuel solenoid valve located on the fuel
pump to control flow of fuel to the combustion chamber.
This solenoid is activated by a pressure switch located
on the unloader valve. When an operator releases the
trigger on the spray gun, the pressure drops, allowing the
pressure switch to activate the fuel solenoid. The solenoid then closes, shutting off the supply of fuel to the combustion chamber. Controlling the flow of fuel in this way
gives an instantaneous burn or no burn situation, thereby
eliminating high and low water temperatures, and combustion smoke normally associated with machines incorporating a spray gun. Periodic inspection is recommended
to insure that the fuel solenoid valve functions properly.
This can be done by operating the machine and checking
to see that when the trigger on the spray gun is in the off
position, the burner is not firing.
Fuel Pressure Adjustment:
To adjust fuel pressure, turn the adjusting screw with a
screwdriver (located on the fuel pump) clockwise to increase, counterclockwise to decrease. Do not exceed
200 PSI.
Air Adjustment
Machines are preset and performance tested at the factory — elevation 100' above sea level. A one time correction for your location will pay off in economy, performance and extended service life. If a smoky or eye-burning exhaust is being emitted from the stack, two things
should be checked.
Next, check the air adjustment on the burner. An oily,
black, smoky fire indicates a lack of air and the air band
should be moved to allow the air to flow through the burner.
Sharp, eye-burning fumes indicate too much air flowing
through the combustion chamber. The air band should be
moved to allow less air to flow through the burner.
