9V.) Getting StartedIMPORTANT: Proper initial installation of equipmentwill assure more satisfactory performance, longerservice life and lower maintenance cost.Make sure the pressure washer is on a level surface andin a protected area where it is not readily influenced byoutside forces such as strong winds, freezingtemperatures, rain, etc. Locate the pressure washer foreasy access for filling fluids, adjustments andmaintenance.It is recommended that a partition be made between thewash area and the pressure washer to prevent directnozzle spray from coming in contact with the pressurewasher. Moisture reaching the equipment will reducethe pressure washer’s service life.V.) VentingDANGER: Do not run machine indoors or in anenclosed area without adequate ventilation or inareas where flammable vapors (gasoline, solvents,etc.) may be present. Do not vent exhaust gases intoa wall, a ceiling or a concealed space.CAUTION: All venting must be in accordance withapplicable federal and state laws and localordinances. Consult local heating contractors.Poor draft will cause the pressure washer to soot andnot operate properly. When selecting the location forinstallation, beware of poorly ventilated locations orareas where exhaust fans may cause an insufficientsupply of oxygen. Proper combustion can only beobtained when there is a sufficient supply of oxygenavailable for the amount of fuel being burned. If it isnecessary to install a unit in a poorly ventilated area,outside fresh air may have to be piped to the burner anda fan installed to bring sufficient air into the unitVI.)
