! ATTENTION !

Contact a chemical supplier for detergent and rinse-aid chemicals.

The chemical supplier can adjust the chemical dispensing pumps too.

1. Adjustment screws are provided for the
dispensing pumps and for the wash tank fill.
They are located on the right-hand side of
the dishwasher behind the lower front access
panel.

2. Make sure the chemical containers are full
and the pick-up tubes are in their proper

4. Run a normal dishwasher 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 run time of the dispensing pump
and CCW to reduce the run time of the
dispensing pump.

6. The Fill adjustment screw will provide a
small change in the tank water level. If
a large adjustment is needed, check the
incoming water pressure and make sure the
fill hose is not kinked. If the above items are
okay then the size of the incoming water
supply should be checked.
The incoming water supply line must be a
minimum of 1/2" or larger.

Minerals (scale) accumulate on the interior surfaces of the dishwasher. The removal of scale
deposits is called de-liming. Inspect your machine interior for scale deposits. If de-liming is
required, a de-liming agent should be used in accordance with your 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.
