Converting Straight-through Operation to Corner Operation

Dishwashers are shipped from the factory for Straight-through operation. Refer to the diagrams
below and on the next page to convert a Straight-through operation machine to a Corner operation
machine. Dish racks enter and exit the sides of a straight-through machine. Dish racks enter the side
and exit the front of corner operation machine.
To convert the dishwasher:

1. Convert the dishwasher before it is placed in its final position and before connecting utilities.

2. The temperature gauges must be clearly visible to the operator when facing the front of the machine.
In addition, the door handles should move freely without interference from walls or other obstructions.
Nominal wall clearance is 6" [152mm]; the minimum wall clearance is 4" [102mm].

Operation

Rinse Sentry Operation Mode

The final rinse water temperature must be a minimum of 180ºF/82ºC during the final rinse cycle to ensure
that all wares are sanitized. If for any reason, the hot water temperature in the booster tank cannot provide
this temperature, the dishwasher will enter a Rinse Sentry Mode of operation and extend the cycle time.

The Rinse Sentry changes the Normal Operation Mode as described below:

1. The Rinse Sentry constantly monitors the water temperature inside final rinse booster.

2. If the temperature inside the booster heater falls below 180ºF/82ºC then the Rinse Sentry
will extend the wash cycle time until the booster heater water temperature reaches the proper
temperature.

3. The in-cycle light will remain illuminated during the Rinse Sentry Mode.

4. The RINSE water temperature gauge must be monitored to ensure that a minimum of
180ºF/82ºC is maintained during the rinse cycle.

5. The temperature range for the final rinse water is 180-195ºF/82-91ºC.

6. An extraordinarily long wash cycle may indicate a low incoming water temperature or a
problem with the booster heater operation.

DO NOT REMOVE WARES UNTIL THE FINAL RINSE CYCLE HAS

SANITIZED THE WARES AND THE GREEN CYCLE LIGHT GOES OUT.

Automatic Drain Cycle

The dishwasher can be drained automatically when the dishwasher has completed a normal wash
cycle or whenever the dishwasher is idle.

To drain the dishwasher:

1. Turn the dishwasher Power Switch OFF. The automatic drain valve will open and the machine
will drain.

Cleaning and Maintenance

De-liming

Minerals accumulate on the interior surfaces of the dishwasher. The deposits have a white
haze and, in cases of heavy accumulation, may appear as a granular solid. The generic
name for mineral deposits is lime. The removal of lime deposits is called de-liming. Your
dishwasher should be
de-limed regularly; how often will depend on the mineral content of your water.

Inspect your machine interior for lime deposits. If de-liming is required, a de-liming agent
should be used for best results in accordance with the chemical supplier's instructions.

Danger:

Death or serious injury may result when de-liming solution is mixed with sodium hypochlorite
(chlorine bleach) 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 protective clothing and goggles when handling chemicals.

Attention:
Contact your chemical supplier for specific safety procedures and instructions for the use of
the de-liming solution supplied for the dishwasher.
De-liming solution or other chemicals are not supplied by the dishwasher manufacturer.
