NOTE:
The chemical dispensing pump speeds are not set at the factory and variations in the
type of chemicals supplied by the chemical supplier always require that the supplier
make nal adjustments for the products supplied.

They are located on the right-side of the glasswasher behind the lower front access panel.
2. Make sure the chemical containers are full and the
pick-up tubes are in the proper containers.
3. Turn the glasswasher power switch ON.
The switch will illuminate and the glasswasher
will ll with water.
4. The chemical supplier should run a normal glasswasher
cycle and test detergent and rinse-aid concentrations
according to the chemical supplier's instructions.
CAUTION:
Excessive pressure to the potentiometers when adjusting can result
in bent or broken adjusting screws.
5. Each dispensing pump has a clearly marked
adjustment screw. Turn the screw CW to increase
the time of the dispensing pump and CCW to
reduce the dispensing pump time.
6. The Fill adjustment screw will provide a small
change in the tank water level. If a large adjustment
is needed, then check the incoming water pressure
making sure the ll hose is not kinked. If the above items
are okay then the size of the incoming water supply
should be evaluated.
7. Detergent, rinse-aid and sanitizer are used.
5.25% sodium hypochlorite (chlorine beach) must be used
as a sanitizing agent to provide a minimum concentration
of 50 ppm in the final rinse. The 50 ppm concentration must
be checked using chlorine test strips to make sure that the
proper concentration is maintained.

De-liming
De-liming
Minerals accumulate on the interior surfaces of the glasswasher. The removal of lime deposits is called
de-liming and the glasswasher should be de-limed regularly. Inspect the machine interior for lime
deposits. If de-liming is required, a de-liming agent should be used in accordance with the chemical
supplier's instructions.
DANGER:
Death or serious injury may result when de-liming solution is mixed with sodium hypochlorite
sanitizing agent. Mixing may cause hazardous gases to form. De-liming solution and other acids
must never be mixed with chlorine, iodine, bromine, or fluorine.
CAUTION:
Skin contact with de-liming solutions can cause severe irritation and possible chemical burns.
Always wear eye protection, rubber gloves and protective clothing when handling chemicals.
