Electric Hot Water/Steam Pressure Washer
Instructions for Set-up, Operation, Maintenance & Storage
This pressure washer produces cold or hot water high-pressure spray as well as steam spray. Cleaning chemicals
may be incorporated into the spray if desired. The pressure pump is powered by an electric motor and water is
heated by an open flame burner fueled by diesel/kerosene or fuel-oil. Read and understand this Owner's Manual
completely before using and keep this manual for review. Failure to properly set up, operate, and maintain could
result in serious injury or death to operator or bystanders.
WARNING: SPECIAL HAZARDS
• Skin/Eye Injury: High-pressure spray can cause serious skin or eye injury, including injection injury if fluid pierces the skin.
Injection injury can result in blood poisoning and/or severe tissue damage.
• Burns: Hot spray can scald and burn skin. Hot surfaces of wand and burner, as well as hot exhaust from the burner can
cause burns.
• Slips/Falls: Spray discharge can cause puddles and slippery surfaces. Spray-gun kickback can cause operator loss of
balance and falls.
• Flying Debris: High-pressure spray can cause surface damage and flying debris.
• Fire/Explosion: Burner sparking can ignite fuel or other flammable liquids or vapors in the vicinity. Hot exhaust from burner
can ignite combustible materials.
• Chemical Exposure: Cleaning chemical vapors or contact with skin may be hazardous.
• Electric shock: Spray contact with electrical sources can cause electric shock.
• Electrocution: Improper connection of the equipment or grounding conductor can result in a risk of electrocution.
• CO Poisoning: Exhaust from burner contains carbon monoxide, a poisonous gas that can cause carbon monoxide poisoning
and possible death if inhaled.
Inspect Upon Delivery: STOP! Closely inspect to make sure no components are missing or damaged. See the
"Assembly and Initial Set-Up" section for instructions on whom to contact to report missing or damaged parts.
Check Pump Oil: Pump is shipped with oil. Check pump oil level before starting.
Water Flow Requirements: Make sure your supply water flow rate is 20% higher than the pressure washer's flow
rate (3 gal/min preferred), and that your water is clean and particle free.
Chemical Spraying: Use only NorthStar brand or equivalent washer chemicals designed for pressure washer use.
Maintenance Schedule: Pump, burner fuel filter, burner coil and electrodes require periodic checking and servicing
to keep pressure washer functioning efficiently. See "Maintenance Schedule Summary" for frequency of servicing.

Inspect Heating Coil and Desoot as Needed Inspect and desoot coil annually. Although most coils never require desooting, poor grades of fuel oil or inadequate combustion air will cause heavy soot build- up on the outside surface of the heating coil tubing. These deposits will insulate the coil, which then restricts airflow through the heat exchanger and further aggravates the soot build-up. -
