MODELS WITH INTERNAL DRAIN PUMPS

The power cord on the internal drain pump is
connected to a 120 VAC wall outlet. The ice
maker is then connected to the 120 VAC outlet
on the drain pump. If the drain pump fails, or if
the drain becomes blocked, power is shut off to
the 120 VAC outlet on the drain pump.
When the unit is first plugged in, the drain pump
will run for 20 seconds. The power can be
disconnected and reconnected to verify that
the pump is operating properly.

ice from the bin, drains down the bin drain tube

into the pump inlet, and then into the drain
pump chamber. As the water level rises, it
bridges the "full" contacts, and the pump starts
to run. The pump discharges the water through
the outlet and the check valve. When the "full"
connection is removed, the pump runs for an
additional 12 seconds to empty the tank.
If the water level in the drain pump continues to
rise, due to a slow or blocked drain, or a
blocked vent hose, and touches the "overfill"
contact, power will be turned off to the drain
pump's 120 VAC outlet, causing the ice maker
to turn off.
