Electrode Setting:
Venting
CAUTION - RISK OF ASPHYXIATION: Do not run
machine indoors or in an enclosed area without the
required venting, as exhaust fumes may be
hazardous to your health.
CAUTION: All venting must be in accordance with
applicable federal and state laws, and local ordinances. Consult local heating contractors.
IMPORTANT: A draft regulator shall be installed.
INSTALLER UNE HOTTE DE TIRAGE.
If the pressure washer is to be used in an enclosed
area, a flue must be installed to vent burner exhaust to
the outside atmosphere. Exhaust gases should not be
vented into a wall, a ceiling, or a concealed space of a
building. Be sure the flue is the same size as the burner
exhaust vent on the pressure washer. Poor draft will
cause the pressure washer to soot and not operate
properly. When selecting the location for installation,
beware of poorly ventilated locations or areas where
exhaust fans may cause an insufficient supply of
oxygen available for the amount of fuel being burned. If
it is necessary to install the machine in a poorly ventilated area, outside fresh air may have to be piped to the
burner and a fan installed to bring sufficient air into the
machine. Locate the pressure washer so that the flue
will be as straight as possible and protrude through the
roof at a proper height and location to provide adequate
draft. This oil fired pressure washer must have a draft
regulator installed in the flue (available from most
heating contractors). A draft regulator will permit proper
upward flow of exhaust flue gases.
Periodically Check Wiring Connections. If
Necessary To Adjust Electrodes, Use Diagram.
Burner Air Adjustment
The oil burner on this machine is preset for operation at
altitudes below 500 feet. If operated at higher altitudes,
it may be necessary to adjust the air band for a #1 or #2
smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need to
be increased; for lower altitude, the air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient temperatures, the air band opening may need to be decreased.
Adjust to your operating location's environment asneeded for best smoke spot and performance
compliant with local, state, and federal regulations.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discontinue use and readjust air bands.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale.
For additional burner component information, see
Burner Assembly Exploded View page. It is recommended that the oil burner be serviced yearly or as
needed. Contact your local service center.

Operations
Fuel Pressure Air Adjustment
Electrical
To adjust fuel pressure, First install a pressure gage
into the port just after the pump fuel exit. Turn the
adjusting screw (located at the regulator port)
clockwise to increase, and counterclockwise to
decrease. Do not exceed 200 psi or lower the pressure
below 130 PSI, when checked at the post-pump
pressure port.
WARNING: Make sure all switches and controls are
in the OFF position prior to connecting electrical
supply.
The fuel pressure may need to be adjusted due to
altitude. For every 500 ft altitude above sea level, the
boiling point of water goes down 1 °F. At high altitude
environments, this boiling point change may require the
heat input to be lowered so the water input does not
turn to steam earlier than at the factory settings and
activate the pressure sensors and pressure relief
equipment when the unit is operated and much higher
altitudes from factory settings or local dealer site
settings. Check with your dealer before making local
site fuel pressure adjustments.
Also, as ambient temperature changes seasonally, the
fuel temperature in the feed tank and air temperature
inlet can impact fuel flow. In more extreme temperatures, this local-site adjustment may also require
different fuel nozzles for fuel inlet temperatures that are
at seasonal extremes (higher or lower) in locations
where the temperature changes are beyond moderate
temperatures of between 40°F and 90°F. Colder
temperatures will make for a thicker flow and less fine a
fuel spray while hotter temperatures will make for a
thinner flow a more fine spray with the same nozzle.
Consider alternate nozzle configurations from the
baseline factory-supplied nozzle for operating in such
temperature extremes if performance is not meeting
needs with air band and fuel pressure settings alone.
NOTE: When changing fuel pump, a by-pass plug
must be installed in return line port or fuel pump will
not prime.
Water Supply
Connect water supply hose to water inlet. The water
faucet and supply hose must be capable of providing a
minimum of 4.0 gallons per minute (GPM) and a
maximum pressure of 65 psi.
WARNING: DO NOT stand in water while
connecting and disconnecting electrical supply.
WARNING: Always disconnect power before
servicing your pressure washer.
IMPORTANT: Consult local building codes for exact
electrical requirements. Licensed contractors may
be required.
IMPORTANT: This machine must be electrically
grounded. LA MACHINE DOIT ÊTRE MISE À LA

4. If HOT water is desired, adjust the thermostat to
the proper temperature and turn burner switch ON.
The burner will light immediately with a small puff
of smoke. You may need to initially adjust your
burner for peak performance. See Oil Burner
section under Installation. If smoke continues,
refer to the Troubleshooting Guide in this
manual. When the trigger of the trigger gun is
released or when the thermostat temperature
setting is reached, the burner will automatically
turn off.
IMPORTANT: If ignition or flame failure is experienced, discontinue use of pressure washer at once.
Turn off burner and shut off fuel supply. Have cause
of failure corrected by an authorized service technician before use of pressure washer is continued.
To Clean
1. Insert detergent inlet line into container of mixed
detergent. Open detergent ON/OFF valve. The
detergent will be pulled automatically into the
system. Allow detergent to reach end of wand
before proceeding to step 3.
2. Select pressure nozzle with spray pattern that
matches your cleaning needs. Engage manual
trigger lock and install selected nozzle.
3. Wash from the bottom to the top, using side to side
motions. This washes away heavy dirt and allows
the detergent to soak as you work toward the top.
4. Do not wash at a 90° angle to the work (straight at
it. This will allow water to splash back at you and
reduces your cleaning power. Wash at a 30° to 60°
angle to the work. This will allow the water to
splash away from you and the water will wash the
dirt away faster and easier.
5. Use the width of the spray pattern to wash in a
wide path. Overlap spray paths for complete
coverage. Wash from side to side, using slow,
steady motions.
6. The nozzle should be 12" to 24" from work, closer
for tough areas. Be careful on painted or delicate
surfaces, the pressure may damage surface if
nozzle is too close.
7. Small parts should be washed in a basket so the
pressure does not push them away. Larger, light
weight parts should be clamped down so the
pressure does not push them away.
8. Close the detergent ON/OFF valve to permit rinse.
Always rinse with cold water after using detergents.
Rinse from the top to the bottom to prevent
detergent from dripping onto a rinsed area. For the
best results, contact your Hotsy dealer to help you
select the best detergent for your application.

Detergents & General Washing Techniques
WARNING
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.
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.
Place the filter end of detergent
suction tube into the detergent
container.
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.

Coil De-scaling: In hard water areas, scale buildup
within the heating coil will occur. Scale deposits will
decrease the water temperature rise and may eventually clog the heating coil. Contact your local service
center when de-scaling is needed.
Coil De-sooting: Poor grades of fuel oil or inadequate
combustion air will cause heavy soot buildup on the
outside surface of the heating coil. These deposits will
insulate the coil. This will restrict the air flow through
the coil, further aggravating the soot buildup. Contact
your local service center when de-sooting is needed.
