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 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 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. Ex-
cess 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 sup-
plied by a minimum 5/8" I.D. garden hose with a city wa-
ter pressure of not less than 30 PSI. If the water supply
is inadequate, or if the garden hose is kinked, the at-
tached 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 car-
bon build-up, which affects the operation, and increases
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.
STARTING AND OPERATING
INSTRUCTIONS
To Start:
1. STOP! Read operator’s manual
before operating. Failure to read
operation and warning instruc-
tions may result in personal in-
jury or property damage.
2. Connect water supply hose and
turn on water.
3. Check fuel tank and pump oil
levels.
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 se-
cure 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 counterclock-
wise.
9. Turn switch to pump position.When a steady stream
of water flows from the spray gun and wand the ma-
chine 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 HPB 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.
OPTIONAL EQUIPMENT
Auto Start/Stop Timer Operation
Once the pump switch is turned on, simply triggering the
spray gun is all it takes to start the machine. Once the
trigger is released the timer will let the machine bypass
water for 15 seconds. It also starts an internal 5 to 60
minute lockout timer.This feature is totally adjustable by
the operator by adjusting the knob at the top of the timer.
We recommend setting the timer for 15 minutes. To re-
set the lockout feature, operator must trigger the spray
for 10 full seconds.
PREVENTATIVE MAINTENANCE
1. Use clean fuel - kerosene, No. 1 home heating 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 wa-
ter pump is properly lubricated.
3. Follow winterizing instructions to prevent freeze dam-
age to pump and coils.
4. Always neutralize and flush detergent from system
after use.
READ OPERATOR’S
MANUALTHOROUGHLY
PRIOR TO USE.
CAUTION

10 HPB SERIES PRESSURE WASHER OPERATOR’S MANUAL
5. If water is known to be high in mineral content, use a
water softener on 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 attached pressure washer pump dry for
extended periods of time.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Maintenance and Service).
10. Never allow water to be sprayed on or near the mo-
tor or burner assembly or any electrical component.
11. Delime coils as 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 equipment clean and
dry.
The areas around the HPB should be kept clean and
free of combustible materials, gasoline and other flam-
mable vapors and liquids.
The flow of ventilating air to the burner must not be
blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Unloader Valves:
Unloader valves trap pressure in the line when a shut-
off spray gun is closed. Machines with unloader valves
are preset and tested at the factory before shipping. Oc-
casional adjustment of the unloader may be necessary
to maintain correct pressure.
Winterizing Procedure:
Damage due to freezing is not covered by warranty. Ad-
here to the following cold weather procedures whenever
the 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 nec-
essary. Store the machine in a heated room. If this is not
possible then mix a 50/50 solution of anti-freeze/water
or windshield washer fluid with water in a 5 gallon bucket.
Place a short section of garden hose into the bucket and
connect it to the machine. Elevate the bucket and turn
the pump on to siphon the anti-freeze through the ma-
chine. If compressed air is available, an air fitting can be
screwed into the inlet connector and by injecting com-
pressed air, all water will be blown out of the system.
If you have an optional float tank, pour the antifreeze
into this tank and run machine until antifreeze exits dis-
charge nipple.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event 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 30 weight non-detergent oil. Change oil
after first 50 hours of use. Thereafter, change oil every
three months or at 500 hour intervals. Oil level should be
checked by using the dipstick found on the top of the
pump or by the red dot visible through the oil gauge win-
dow. 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 de-
tergents. In areas where alkaline water is an extreme
problem, periodic use of Deliming Powder will remove
lime and other deposits before coil becomes plugged.
Deliming Coils With A Pressure Washer:
Periodic flushing of coils is recommended.
Step 1 Fill a 5 gallon bucket with 4 gallons of water, then
add 1 lb. of deliming powder. Mix thoroughly.
Step 2 Remove the high pressure nozzle from the pres-
sure wand and put the wand into the bucket. Se-
cure the trigger on the spray gun into the open
position.
Step 3 Attach a short section (3-5 ft.) of garden hose to
the attached pressure washer to siphon solu-
tion from the elevated bucket. Start up pressure
washer, allowing solution to be pumped through
pressure washer and into HPB coils and back
into the bucket. Solution should be allowed to
circulate 2-4 hours.
Step 4 After circulating solution flush entire system with
fresh water.
Removal of Soot In Heating Coil:
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 re-
moved using the following steps:
1. Remove the tank head assembly by unscrewing the
three tek screws and 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.

HPB SERIES PRESSURE WASHER OPERATOR’S MANUAL
11
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 ex-
ceed 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 mal-
function could result from contamination.
Ignition Circuit:
Periodically inspect wires, spring contact and electrodes
for condition, security and proper spacing. For trans-
former 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" be-
tween end of blade and other contact (see illustration).
Electrode Setting:
(See illustration below)
Burner Nozzle:
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 HPB utilizes a fuel solenoid valve located on the fuel
pump to control the flow of fuel to the combustion cham-
ber.This solenoid is activated by a pressure switch located
on the unloader valve.When an operator releases the trig-
Electrodes Check: Periodically check wiring connections.
If necessary to adjust electrodes, use diagram.

ger on the spray gun, the pressure drops, allowing the pres-
sure 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 eliminat-
ing high and low water temperatures, and combustion
smoke normally associated with machines incorporating
a spray gun. Periodic inspection is recommended to in-
sure 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
5/32" allen wrench (located on the fuel pump) clockwise
to increase, counterclockwise to decrease. Do not ex-
ceed 200 PSI.
Air Adjustment
Machines are preset and performance tested at the fac-
tory — elevation 100' above sea level. A one time cor-
rection for your location will pay off in economy, perfor-
mance and extended service life. If a smoky or eye-burn-
ing exhaust is being emitted from the stack, two things
should be checked.
First, check the fuel to be certain that kerosene or No. 1
home heating fuel is being used.
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 white 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.
