INSTALLATION INSTRUCTIONS

Getting Started
IMPORTANT: Proper initial installation of equipment will assure more satisfactory performance, longer service life and lower maintenance cost.
WARNING: If connection is made to a potable water system, the system shall be protected against backflow.
AVERTISSEMENT: Si une connexion est établie avec un réseau d’eau potable, le réseau doit être protégé contre le retour d’eau.
ADVERTENCIA: Si se realiza una conexión a un sistema de agua potable, el sistema debe estar protegido contra el reflujo.

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.

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 applicable federal and state laws, and local ordinances. Consult local heating contractors.
ATTENTION: Toute la ventilation doit être conforme aux lois fédérales et de l’État ou de la province, et aux réglementations locales applicables. Consulter des entrepreneurs en systèmes de chauffage locaux.

NOTE: This product is labeled of outdoor use only and should be operated outdoors. It is not recommended to operate indoors. If under certain conditions that make it impossible to operate outdoors you can operate indoor using a hood vent or venting. Venting can cause restriction of air flow through the combustion chamber causing excessive soot. Use a larger vent size then the exhaust stack to prevent restriction and contact the local servicing dealer to adjust the air mixture after installation of vent.
Burner Air Adjustment
The oil burner on this machine is preset for operation at altitudes below 1,700 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.

PRECAUCIÓN: Toda la ventilación debe ser de acuerdo con las leyes federales y estatales aplicables y las ordenanzas locales. Consulte a contratistas locales de calefacción. 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. See Component Identification for location. Poor draft will cause the pressure washer to soot and not operate properly. When selecting the location for

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 as needed for best smoke spot and performance compliant with local, state, and federal regulations. 11

CAUTION – Never use:

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

· Bleach, chlorine products and other corrosive chemicals
· Liquids containing solvents (i.e., paint thinners, gasoline, oils)
· Tri-sodium phosphate products · Ammonia products · Acid-based products

GENERAL CLEANING TECHNIQUES & STORAGE

RINSING
It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Select and install desired high pressure nozzle. NOTE: You can also stop detergent from flowing by removing detergent siphon tube from bottle.
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 Component Identification 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.

Lubrication: To lubricate pump, use 30W nondetergent oil for pump crankcase. Crankcase must be filled to center of sight glass window found on the side of the pump; refer to Figure 5. During the break-in period, make sure the oil is changed after the first 50 hours of operation. After that, replace oil every 3 months or at 500 hours intervals, thereafter.
Oil Fill/Dip Stick

Proper Pump Care:
· DO NOT pump acids. · DO NOT allow pump to run dry. · Winterize if storing in freezing temperatures.
Refer to Storage 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
periodically. · Flush the pressure washer system with
antifreeze if storing for an extended period of time, refer to Storage for details.

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.
