3. Sequence of Electrical Circuit
[a] When power switch is moved to “ON” position and flush switch to “ICE” position,
water starts to be supplied to reservoir.
17
[b] When reservoir has been filled, gear motor starts immediately.
18
[c] Compressor starts about 60 sec. after gear motor starts.
19
[d] Bin control operates, and about 6 sec. later, compressor and gear motor stop
simultaneously.
