4. 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.

5. Turn Your Pressure Washer ON

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

6. Turn 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.
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.

7. 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 formulated 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.
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 Heat Switch to the "OFF"
position 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.
