[d] Controls and Adjustments

The Dip Switch is factory-adjusted to the following positions:
Switch Nos. 1 and 2:
Used for adjustment of the defrost timer.
The defrost timer starts counting when the thermistor reads a certain temperature at the
evaporator outlet.
Switch Nos. 3 and 4:
Used for adjustment of the drain timer.
When a freeze cycle is completed, the pump motor stops, and the icemaker resumes
operation in 2 seconds. Then the pump motor drains the water tank for the time
determined by the drain timer. The drain timer also determines the time to restrain
completion of a defrost cycle, i.e. the minimum defrost time.
Switch Nos. 5 and 6:
Used for adjustment of the drain counter.
The pump motor drains the water tank at the frequency determined by the drain
counter.
Switch No. 7:
Used only on models with mechanical bin control. Dip switch should be set "ON".
(Models with bin thermostat, switch no. 7 should be set in the "OFF" position.)
Switch No. 8:
Used only for checking the controller board. Usually set in OFF position.
Switch Nos. 9 and 10:
Used for adjustment of freeze timer.
The freeze timer determines maximum
freeze cycle time. Upon termination of
freeze timer, machine initiates the
harvest cycle. After 2 consecutive timer
terminations, machine will shut down,
possibly indicating a problem.
