Northern Industrial Tools 157494 IV. To Start, Turn Your Pressure Washer on, VII. To Clean

IV.) To Start

DANGER: Do not point the spray wand at yourself or at any person. Bodily injury may result from hot water or water under high pressure.

WARNING: Wear eye, ear, hand, foot, and skin protection at all times while operating this water heater.

1.Turn water supply ON.

2.Squeeze the trigger to allow air to purge from the system. This step goes faster with the pressure nozzle removed.

V.) Turn Your Pressure Washer ON.

1.Follow your pressure washer’s manual for its start-up procedure.

VI.) Turn The Water Heater ON

1.Make sure there is fuel in the fuel tank.

2.Turn the heat switch ON, and adjust the thermostat to the desired temperature.

3.The burner will fire when the trigger is squeezed. You may need to initially adjust your burner for peak performance. See the “Oil Burner” section under

INSTALLATION.

4.When the trigger is released or the temp setting is reached, the burner will automatically turn off.

IMPORTANT: Do not run the machine in hot mode without any fuel in the fuel tank. The fuel pump will be damaged if it is run dry.

VII.) To Clean

WARNING: Wear eye, ear, hand, foot, and skin protection at all times while operating this water heater.

DANGER: Do not point the spray wand at yourself or at any person. Bodily injury may result from hot water or water under high pressure.

CAUTION: Be careful on painted or delicate surfaces. The pressure may damage the surface if the nozzle is too close.

WARNING: Only use NorthStar pressure washer chemicals or chemicals specifically formulated for pressure washers. Follow the chemical manufacturer’s recommendations. Understand all safety precautions and first aid for all chemicals.

1.If your pressure washer is equipped with a quick connect chemical injector, it can be snapped onto the high pressure water outlet. Then snap the high pressure hose to the injector and submerge the suction strainer into the chemical solution.

2.If your chemical injector cannot be moved to the water heater’s outlet, it is acceptable to run chemicals through the heating coil. Only use NorthStar pressure washer chemicals or chemicals specifically form-ulated for pressure washers, and make sure that the coil is flushed completely with clean water after chemical use.

3.Spray detergent onto the surface and allow it to soak. Chemicals need time (dwell time) to work properly.

Follow the chemical manufacturer’s recommendations for dwell time.

4.Hold the lance with two hands. Have a sturdy stance.

5.Point lance at dirty surface and squeeze trigger.

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.Use the width of the spray pattern to wash in a wide path. Overlap spray paths for complete coverage.

8.The nozzle should be 12” to 24” from the work, closer for tough areas.

Caution: Be careful on painted or delicate surfaces. The pressure may damage the surface if the nozzle is too close.

9.Small parts should be washed in a basket so the pressure does not push them away. Larger, light- weight parts should be clamped down.

VIII.) To Stop

1.If detergents were used, draw clear water through the detergent inlet line to purge detergent. Failure to do so may clog the chemical injector.

2.If the burner was used, turn off the “Heat” switch and pump cold water through the coil for 3 minutes. Insufficient cool down period of high pressure hose will cause excessive wear and eventual rupturing of hose.

3.Turn the pressure washer OFF.

4.Turn OFF the water supply.

5.Squeeze the trigger to relieve the system pressure.
