62 Part Number: 000015431 Rev 02 6/20
Water Inlet Valve
The water inlet valve energized in prechill. After water
contacts the low and high water probes the water fill valve
de-energizes. Ice builds on the evaporator and the water
level drops. When water loses contact with the high water
probe, the water fill valve energizes until water contacts
the high water probe again.
Maximum Fill Time = Prechill fill time + first fill + second fill.
SINGLE EVAPORATOR MAXIMUM FILL TIME
Initial startup or startup after automatic shutoff
Prechill (2 minutes) + first fill time (6 minutes) + second fill
time (6 minutes) = 14.0 minutes.
Consecutive cycles
Prechill (30 sec.) + first fill time (6 minutes) + second fill
time (6 minutes) = 12.5 minutes.
DUAL EVAPORATOR MAXIMUM FILL TIMES
Initial startup or startup after automatic shutoff
Prechill (2 minutes) + first fill time (8 minutes) + second fill
time (8 minutes) = 18.0 minutes.
Consecutive cycles
Prechill (30 sec.) + first fill time (8 minutes) + second fill
time (8 minutes) = 16.5 minutes.
