Installing Reservoir
(continued)
5. Route water line from circulation pump between
liner and reservoir and through clamp attached
to evaporator. This will keep it away from path
of ice slab (see
Figure 23
).
6. Reinstall ice deflector.
7. Reinstall cutter-grid.
8. Plug cutter-grid into receptacle on side of liner.
Route plug wire between reservoir and liner.
This will keep it away from path of ice slab.
9. Reinstall escutcheon panel. Adjustment to
brackets may be necessary to align escutcheon
panel.
Circulation Pump
The circulation pump is used to circulate the water
in the reservoir over the evaporator. The circulation
pump will run only during ice production cycle and
turn off in ice harvest cycle and also when called on
for the clean cycle.
The pump is a centrifugal impeller type pump. The
pump and motor are an assembly that cannot be
repaired separately.
To check circulation pump
(with the pump removed)
• Make sure motor shaft turns freely. This can be
done by rotating the pump’s drive shaft and
observing any excessive resistance. Axial motor
shaft movement (thrust) is typical.
• Check for resistance between the terminals. If
no resistance is found, replace the circulation
pump.
• Check for continuity between the hot and
neutral terminals and the pump’s motor casing.
If continuity is found, replace the circulation
pump.
• Check current draw. Typical current draw will be
0.36 amp without pump resistance. If excessive
current draw is found, check the pump’s
impeller for foreign particles or severe build-up
of mineral deposits.
• The circulation pump can run dry without pump
damage.
Figure 23
Make certain that the water line is in the clamp
and away from the path of the ice slab.
Otherwise, the ice slab may hang-up.
