MAINTENANCE AND CLEANING
///////////////////////////WARNING/////////////////////////////
Disconnect electrical power before beginning.
//////////////////////////////////////////////////////////////////////////
1. The ice machine senses water level by a probe
located in the water reservoir. At least twice a
year, the probe should be removed from the
reservoir, and the tip wiped clean of mineral
buildup.
2. The bin control uses devices that sense light,
therefore they must be kept clean enough so that
they can "see". At least twice a year, remove the
bin control sensors from the grommets in the ice
chute, and wipe them clean.
3. The bearing in the breaker should also be
checked at least two times per year.
A. Check the bearing by:
••
removing the ice chute cover
••
unscrewing the ice sweep
••
removing the water shed
••
using a spanner wrench and unscrewing the
breaker cover.
••
unscrewing the auger stud
Inspect the assembly, looking for wear.
See Removal and Replacement to replace
bearing or seals. Reverse to reassemble.
4. Check and tighten all bolts and screws.
