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 fi rst 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 "overfi ll"
contact, power will be turned off to the drain
pump's 120 VAC outlet, causing the ice maker
to turn off.
