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.
