Chemical
CAUTION: Chemical mixture
The special NorthStar braided chemical hose when
placed within a liquid and attached at the pump’s
chemical injection port will inject 1-part chemical to 15
parts water. Chemicals must be pre-diluted in
accordance to instructions to accommodate the
additional 15:1 dilution ratio which will occur in the
pump.
Chemical Spraying Preparation:
• Prepare (dilute) cleaning solution as required for
the job. (Recall that this chemical solution will be
automatically mixed in the pump with water at a
ratio of 15 parts water to 1 part diluted chemical
solution.)
• Press braided chemical hose over the pump’s
chemical injector.
• Submerge suction strainer connected to braided
chemical hose into chemical solution bucket.
• Make sure the BLACK nozzle is attached to spray
wand before beginning to spray chemicals –
High-pressure nozzles cannot apply chemicals.
• Warm or cold water can be used. If warm water
is specified on chemical label, start burner
according to the instructions in the following
section, “Hot Spray Procedure.”
Chemical Spraying Procedure:
• Disengage safety latch and apply chemicals
evenly to the cleaning surface working from
bottom upward, using long, even, and overlapping
passes.
• Allow chemicals time to react with dirt before
rinsing. Do not allow the chemical to dry on,
reapply as needed to prevent surface from drying.
Rinsing:
• Change to a high-pressure nozzle for rinsing.
Changing to a high-pressure nozzle will
automatically stop the flow of chemicals into the
water stream.
• Rinse with high-pressure spray, either hot or cold.
• Turn heat switch ON and adjust thermostat to desired
temperature. (For steam spraying, set temperature at
212F or higher and use YELLOW nozzle.)
• Burner will only fire as trigger is squeezed – follow
instructions for spraying.

Hot Spray Procedure
CAUTION: Metal burn hazard
Use of burner will make spray gun hot. Avoid touching
wand. Serious burns from hot metal could occur if
touched.
• Before starting burner, make sure vicinity is free of
flammable vapors, dust, gases, or other potentially
combustible materials. Operate only where open
flame or torch is permitted and neither flammable
vapors nor combustible objects are present.
• Ensure there is fuel in burner fuel tank.
• Wait before re-lighting burner. NEVER attempt to
immediately re-light the burner if it does not ignite the
first time. Unburned oil or gas may have
accumulated, causing potential explosion or fire
hazard.
• Burner automatically turns off when trigger is
released or when temperature setting is reached.
Note: If burner exhaust is white, adjust burner for
peak performance. See “Oil Burner Adjustment”
section towards the back of this manual.
