2. Remove pressure washer from pallet.

Parts Included

• Pressure Washer
• Pressure Hose
• Wand Assembly
• Operating Instructions and Parts Manual
• Teflon Tape

Tools Required

• 10″ Adjustable Crescent Wrench (2 ea.)

Pressure Hose

1. When assembling, use teflon tape on all plumbing connections to prevent leakage.
2. Install high pressure hose on machine as shown in Figure 1.
3. Assemble pressure hose onto trigger gun/wand assembly as shown in Figure 2.
4. Make sure that all plumbing connections are tight.

INSTALLATION

Getting Started
IMPORTANT: Proper initial installation of equipment will assure more satisfactory performance, longer service life and lower maintenance cost.
IMPORTANT: The use of a backflow preventer on the water supply hose is recommended and may be required by local code. The pressure washer should be run on a level surface where it is not readily influenced by outside sources such as strong winds, freezing temperatures, rain, etc. The pressure washer should be located to assure easy access for filling of fluids, adjustments and maintenance. Normal precautions should be taken by the operator to prevent moisture from reaching the pressure washer. It is recommended that a partition be made between the wash area and the pressure washer to prevent direct spray from the wand coming in contact with the pressure washer. Moisture reaching the equipment will reduce the pressure washer’s life. All installations should comply with the local codes covering such installations. Venting
CAUTION: All venting must be in accordance with ap-plicable federal and state laws, and local ordinances. Consult local heating contractors. 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 lid. 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. Proper 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 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.

INSTALLATION & OPERATION INSTRUCTIONS

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 tempera-tures, the air band opening may need to be decreased. Adjust to your operating location’s environment as-needed for best smoke spot and performance compliant with local, state, and federal regulations.

Electrical Connections
WARNING: Make sure all switches and controls are in the OFF position prior to plugging in.
CAUTION: This pressure washer is equipped with a UL approved ground fault circuit interrupter (GFCI) power cord. Use UL grounded type receptacles of proper voltage and amperage ratings. Where a properly grounded receptacle is not available, it is the personal responsibility of the owner to have one installed. Always disconnect power before servicing your pressure washer. Connect electrical cord and test the GFCI using the reset and test procedures provided on the GFCI device. The GFCI must be reset and tested with every use. Do not use machine if the GFCI device fails test. Pressure Nozzle/Trigger Lock Installation

IMPORTANT: If the pressure washer has not been used for an extended period of time, remove the nozzle from the end of the wand and turn on water supply. Allow water to run from the end of the wand until clear.

1. Install adjustable pressure nozzle on end of the wand.

See Figure 4. IMPORTANT: The trigger gun provided with this pres-sure washer is equipped with a manual trigger lock to prevent accidental operation of the trigger gun. The trigger lock should be used whenever the trigger gun is not in use.
To Start
IMPORTANT: The water must be turned on before starting. Running the pump dry will cause damage to pump seals and void warranty.
IMPORTANT: DO NOT allow the machine to run in bypass for more than 10 minutes at any one time or damage to pump may  occur.

1. Turn water on.
2. Hold gun firmly, squeeze trigger of trigger gun and turn pump switch ON. Allow air to purge from system.
3. If HOT water is desired, turn burner switch ON. Adjust thermostat to desired temperature. The burner will fire immediately with a small puff of smoke. If smoke continues refer to the Troubleshooting Guide in this manual. When the trigger gun is closed the burner will turn off.

To Stop

1. If detergents were used, draw clear water through the detergent line to purge detergent.
2. If burner was used, turn off burner switch and allow pump to run cold water through coil.
3. Push OFF pump switch.
4. Turn OFF water supply.
5. Squeeze trigger gun open to relieve system pressure.

NOTE: If the machine is unplugged from receptacle, you must reset the GFCI power cord when machine is plugged in. Always test GFCI before each use. See instructions in the Electrical Connections section of this manual.

OPERATION INSTRUCTIONS & CLEANING TECHNIQUES

GENERAL CLEANING TECHNIQUES

Warning: Pressure washers produce a kickback. To prevent personal injuries due to falls use auxiliary safety equipment. The detergent injector valve operates by reducing the volume of water, thus a vacuum is achieved and detergent is drawn into the system. DO NOT reduce the water inlet flow so much as the pump cavitates because of water starvation. Operating a pump with insufficient water will damage the pump seals.

1. Insert detergent line and screen into container of detergent.
2. Completely open detergent control knob located on the side of the detergent injector valve.
3. Start the detergent suction by rotating the water adjustment knob of the detergent injector valve. See Figure 5. Turning the knob counterclockwise will pull detergent into the system. The flow may be observed
4. The side control knob can now be adjusted to meter the desired amount of detergent.
5. Select the width of your nozzle spray pattern by turning the black knob on the nozzle. See Figure 6. Pattern can be from 0 degrees through 80 degrees fan spray. Release the trigger of the trigger gun prior to making any spray pattern adjustments.
6. 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.
7. Do not wash at a 90o angle to the work (straight at it). This will allow water to splash back at you and reduces your cleaning power. Wash at a 30o to 60o 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.
8. Use the width of the spray pattern to wash in a wide path. Overlap spray paths for complete cover-age washing from side to side, using slow, steady motions.
9. 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.
10. 10. Small parts should be washed in a basket so the pres-sure does not push them away. Larger, lightweight parts should be clamped down so the pressure does not push them away.
11. Turn the side detergent control knob clockwise (CW) for detergent decrease. Wait for detergent to clear. Always rinse with cold water after using detergent. 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.

STORAGE & MAINTENANCE

STORAGE

Protect from freezing by storing in a heated area, or by flushing the system with antifreeze (use an automotive engine antifreeze or windshield washer solvent to antifreeze). To flush the system with antifreeze, attach a short length of hose to the garden hose connector located on the pump. Place the other end of the hose into a container of antifreeze. Start machine and allow to run until antifreeze flows from the end of the wand. Squeeze and release the trigger of the trigger gun several times to antifreeze the unloader system. Also draw antifreeze through the detergent inlet line to antifreeze the detergent system. For added protection after anti-freezing, disconnect the pressure hose from machine and remove the coil drain plug (refer to Exploded View for location). After coil has drained, replace pressure hose and coil drain plug. If the pressure washer is not to be used for an extended length of time, it is recommended that the system be flushed with antifreeze for rust protection.

MAINTENANCE

WARNING: Unauthorized machine modification or use of non-approved replacement parts may cause personal injury and/or property damage and will void the manufacturer warranty.
Pump
Lubrication: To lubricate pump, use 30W non-detergent oil for pump crankcase. Crankcase must be filled to the full mark on the dipstick or to center of sight glass window found on the side of the pump, refer to Figure 7. During the break-in-period, make sure the oil is changed after the first 25 hours of operation. After that, replace oil every 3 months or 300 hours, whichever comes first.

Proper Pump Care

• DO NOT pump acids.
• DO NOT allow pump to run dry.
• Winterize if storing in freezing temperatures, refer to Storage & Maintenance for details.
• Use a water softener on the water system if known to be high in mineral content.
• Use only high quality detergents and follow manu-facturer’s mix recommendations.
• Flush the system with clear water immediately after using detergent solutions.
• Clean filter screen on detergent inlet line periodi-cally.
• Flush the pressure washer system with antifreeze if storing for an extended period of time, refer to Storage & Maintenance for details.

Pump Motor
On a yearly basis, oil pump motor per instructions on motor nameplate.
Unloader Valve
WARNING: The unloader valve on this pressure washer has been factory set and sealed and is a field nonadjustable part. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturer warranty. For replace-ment parts refer to Pump Assembly.
Burner Fuel Filter
Drain any water which has accumulated in fuel filter and clean or replace element as needed. For replacement parts, refer to Burner Assembly.
Heating Coil
Coil Descaling: 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 descaling is needed.
Coil Desooting: 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 desooting is needed.
Relief Valve
WARNING: The relief valve on this pressure washer has been factory set and sealed and is a field non-adjustable part. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturer warranty. For replacement parts refer to Coil Outlet Assembly. If pressure from pump or thermal expansion should exceed safe limits, the relief valve will open, allowing high pressure to be discharged through hose to ground. Caution: Inspect relief valve annually for any obstruction.
