MEI 10-9-12 14For Indoor Hot Water/Burner UseExhaust:• Hot fumes from burner must be exhaustedthrough a hood or piped to the outside.• Place the unit so that the exhaust fumes will notbe directed towards people or building air intakes.Precautions:• Keep a fire extinguisher rated “ABC” nearby.Keep it properly charged and be familiar with itsuse.• Ensure that working, battery-operated or batteryback-up carbon monoxide alarms are used in anystructure that is in close proximity to the runningpressure washer.• An abundant amount of air must be available forproper combustion and cooling. Do not install insmall, enclosed areas without an amplecirculation of supply air.• For more details, refer to NFPA 31: Standard forthe Installation of Oil-Burning Equipment.Chapter 5 provides guidelines on how to ensureadequate air is provided for safe combustion.DANGER: Carbon monoxide poisoninghazardExhaust fumes from the burner contain carbonmonoxide (CO), a poisonous gas you cannot see,smell, or taste. The CO generated by the pressurewasher can rapidly accumulate, even in areas thatappear to be well ventilated, resulting in dangerous andfatal concentrations within minutes. ONLY run pressurewasher outdoors and away from air intakes. NEVER runpressure washer inside any enclosed or semi-enclosedspaces, including homes, garages, basements, sheds,boxes, pick-up truck beds, RVs, or boats. These spacescan trap poisonous gases, EVEN if you run a fan oropen windows. If you start to feel sick, dizzy, or weakwhile using the pressure washer, shut off the motor andget to fresh air RIGHT AWAY. See a doctor. You mayhave carbon monoxide poisoning.OperationStep 1. Connect Hoses, Water Supply, andSpray NozzleNote: The electrical power and pump are both offduring Step 1 procedures.Hose and Water Supply• Water supply should be standard, clean, tap water.• To allow adequate flow and pressure, acquire a 5/8”flexible garden hose (3/4” if over 100 ft. long).Note: A backflow preventer at the water supply isrecommended and may be required by local code.(Part #222815 call 1-800-270-0810 to order)• Attach garden hose to water supply, making surehose is not kinked.• Flow rate at end of supply hose should be 3.0 gpm orhigher and between 20-100 psi, depending onmodel.Connect Water Supply to Pump• Confirm rubber washer and inlet filter screen are inwater pump inlet. (See #2 in “ComponentIdentification” section for location of water inlet.)• Run water through garden hose for 30 seconds toclean out debris. Turn off water.• Connect garden hose to water pump inlet onpressure washer and turn on water valve.Connect Pressure Hose to PumpUncoil high-pressure hose. Attach quick connect end ofhose to pressure washer’s water outlet and other end ofhigh-pressure hose to spray gun by following the “QuickConnect Procedure” below.WARNING: Incompatable componenthazardNEVER operate this pump with components (such ashose, connections, and spray gun) rated for lowerpressure and/or temperature limits than the machine’smaximum rated pressure and temperature, orcomponent will likely rupture and cause seriouspersonal injury from escaping high pressure fluids.Quick Connect Procedure• Pull quick connect collar back (Figure 9a).• Push hose or nozzle firmly against stop.• Let go of collar (Figure 9a).• Pull (hose or nozzle) to assure a tight connection.WARNING: Projectile hazardSprayer nozzle can become a projectile and causeserious personal injury or damage if not properlyconnected to the spray gun.
