DRAIN PUMP INSTALLATION AND MAINTENANCE
6. Unfasten the drain pump ground wire connection, see
Figure 10, and remove the drain pump from the ice
machine.
7. Disconnect the electrical plug connection from the side
of the drain pump, see Figure 13.
8. Disconnect the cabinet power cord from the drain
pump. (See Figure 13).
9. Reverse this procedure to assemble the new drain
pump into the cabinet and re-install the leveling leg to
its original position.

CAUTION
!
When replacing tube clamps, do not overtighten which
could damage the tubing. Tighten screws until "snug", then
retighten several minutes later after the material relaxes, to
assure a water tight connection.
NOTE
The vent tube must be attached and secured or water
damage may occur. Make sure there are no kinks in the
tube. The drain pump will not operate correctly with a
partially blocked vent tube.

Maintenance
The following items require review on a regular basis.
• Check that the ice bin drain inside the cabinet is open
and free of foreign material which would block water
flow to the drain pump, see Figure 14.
• Check that the inlet tubing from the ice machine drain
valve to the drain pump is open and free of foreign
material. Inspect the screen at the top of the inlet tube
to ensure there is nothing blocking the water flow to the
pump, see Figure 15.
• Check that the vent line is open, free of kinks and sharp
bends so that the air can flow freely from the pump
reservoir. See Figure 9 on page 8.
• Check that the discharge tubing is free from foreign
material (algae, etc.) and kinks and bends. Pour water
in the ice bin to confirm that the check valve is opera-
tional by observing that the water flow is evident in one
direction only, out of the pump. Remove and clean as
required.
