The first pump-out occurs after the 1st freeze cycle, then every 10th cycle thereafter.
The pump-out frequency is factory set, and generally no adjustment is required.
However, if the icemaker needs a pump-out more often due to local water conditions,
the pump-out frequency can be adjusted. The pump-out frequency control (S1 dip
switch 5 & 6) can be set to have a pump-out occur every cycle, or every 2, 5, or
10 cycles. For details, see "II.C.3.d) Pump-Out Frequency Control (S1 dip switch 5
& 6)." Diagnosis: If PM does not run, check to see if pump-out/drain selector (S2
dip switch 1) setting is in the factory default position. Check PM circuit and capacitor,
and PM terminal on the diagnostic connector (violet wire) for voltage. For diagnostic
connector details, see "III.B.2. Diagnostic Connector." If DV does not open, check
the supply voltage at DV terminals, and check continuity on the coil. If water does not
pump-out, check and clean the tubing at DV, then check and clean DV assembly.
7) Normal Harvest Cycle – same as the initial harvest cycle – See "IV.A.4) Initial Harvest
Cycle."
8) Shutdown – See "IV.C.1. Bin Control Check." Note that after a bin-control initiated
shutdown, there is a 90 second minimum off time.
