TO RINSE:
A. Close the chemical metering valve buy turning
clockwise. If the gun assembly is equipped with a dual
lance wand open the valve.
NOTE: It is advisable to dip the chemical screen in a
container of clean water and open the valve 1 minute
to clean the valve of any remaining residue.
B. If the gun assembly is equipped with variable or
multiple nozzle assembly, open and close to clean
nozzle of any remaining residue.
C. After a clear flow of water is noted from the end of
the wand, Engage the trigger safety latch on the spray
wand. Pull back the Quick-Connect collar on the end
of the wand and remove the tip. Now insert high
pressure tip into the fitting, and release the collar.start
from the top, working downward using long,
overlapping strokes.
NOTE: Machines with PRESSURE SWITCHES,
because of lower pressures may lose heat during
soaping.
1. Turn the switch to the “pump” position. (If not already
done so in the cold water rinse.)
2. After cool, clear water is coming from the end of the
wand, turn switch to the “off” position .
3. Turn off the water supply.
4. If freezing conditions may exist, refer to STORAGE
in MACHINE MAINTENANCE.
5. Replace stack cover (if so equipped).
CAUTION: You cannot draw an abrasive product such
as an aluminum brightner. It will cause an
non-warrantable premature pump failure.
TO CLEAN:
A. Start on the lower portion of the area to be cleaned
and work up using long, even, overlapping strokes.
B. Dirt is generally removed easily if grease and/or
oil are not present. However if grease and/or oil
are present, hot water and chemical will
accelerate in the cleaning process.
4. TO APPLY CHEMICAL:
Upstream Chemical Injection
When injecting chemicals “upstream” what you are do-
ing is introducing chemicals to the water flow as it enters
the actual pump inlet and requires a float tank. The popu-
larity of this type of chemical injection is due to the fact
that this allows chemicals to be applied at full pressure
a major advantage for productivity.
Downstream Chemical Injection
Mounted to the outlet of the pump or the coil a down-
stream injector introduces chemicals to the water flow
AFTER it leaves the pump or the coil. This effectively
eliminates the major risks of exposing the inner work-
ings of a pump to harsh chemicals. When chemical is
desired, the system must be switched over to the low
pressure nozzle to draw chemical.
A. Engage the trigger safety latch on the spray wand.
Pull back the Quick-Connect collar on the end of the
wand and remove the tip. Now insert “black” tip into the
fitting, and release the collar. You can draw chemical
only with the “black” low pressure nozzle.Tug on spray
tip to make sure the connection is secure. Rotate to
desired spray angle. For most effective cleaning, keep
spray tip from 8 to 24 inches away from the cleaning
surface.
B. Insert chemical screen into chemical container.
C. Turn the burner switch to the “off” postion.
There will be air in the chemical line. Air heats very
quickly and needs to be eliminated before the burner can
be turned on.Open the metering valve counter clockwise
with the trigger gun open allowing the chemical to come
up the chemical line. Chemical should begin moving up
the chemical line. Once the chemical line is completely
full, trigger the gun on and off numerous times to break
any possible air locks. Turn burner system switch to
“on” position.
D. If the gun assembly is equipped with variable or
multiple nozzle assembly, adjust to low pressure.
E. If the gun assembly is equipped with a dual lance
wand open the valve.
Do not allow the detergent to dry on the surface
(prevents streaking).
