4. Make sure all wash and rinse arms are in position and
spin freely. Tighten the lower spindle (turn clockwise)
and upper wash rotor nut by hand.
5. Scatter initial charge of detergent into scrap screens.
Replenish as needed. This may not be necessary on
dishwashers that have an external chemical dispenser.
6. Close the counterbalanced three-way hood.
7. Place the power switch in ON (up) position. The tank
will begin to fill and the tank heat will initiate when
the water reaches the appropriate level.
8. When the wash tank thermometer reads between 150°F
and 160°F, the dishwasher is ready for use. If after a short
period of time this temperature is not attained, adjust
the thermostat located in the control box.
WARNING
Before performing any service that involves electrical
connection or disconnection and/or exposure to
electrical components, always perform the Electrical
LOCKOUT/TAGOUT Procedure. Disconnect all circuits.
Failure to comply with this procedure can cause
property damage, injury or death.
Note: Adjusting the thermostat is a user function and is
not covered under the warranty.
Automatic Tank Fill (Standard)
The dishwasher is equipped with an automatic tank fill
system that utilizes a liquid level control. The unit will fill
automatically when the power switch is placed in the ON
(up) position. The tank takes approximately 3 minutes to
fill completely.
Note: The liquid level control will automatically maintain
the water level in the wash tank to within 3 inches
of the top of the standpipe when the unit is ON.
When the dishwasher is cycled, the final rinse will
bring the water level up to the top of the standpipe.
Wash Cycle Selector (Optional)
This feature allows the user to choose between wash cycle
times. Choices are 1, 2, 4 and 6 minutes. The rinse cycle
is a set time of 12 seconds and cannot be changed. On
double units, each side will operate on the same cycle time.
