When cleaning filters, check whether dangerous
•
chemicals have been used with the filter and take
any precautions that may have been
recommended by the supplier of these chemicals.
Always dispose of hazardous fluids per local,
•
state, and national guidelines.
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.
Operation

Turn heat switch ON and adjust thermostat to
•
desired temperature. (For steam spraying, set
