[d] CONTROLS AND ADJUSTMENTS
The Dip Switch is factory-adjusted to the following positions:
FOR MODELS WITH MECHANICAL BIN CONTROL:
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.)
