Gear Motor; Condenser (Air-Cooled Model Only); Air Filter (Air-Cooled Model Only) - Hoshizaki FM-170,300AKE(-N) Service Manual

Attach the mechanical seal with its floating sheet facing the housing. After replacement,
there should be no water leakage from the mating surface.
Note: The water leakage will exceed the above amount with scale/dirt build up or damage
on the mating surface. Replace the mechanical seal when the water leakage exceeds
0.5 mL/h.

3. GEAR MOTOR

After the following hours of operation, check the gear motor for excessive noise caused by
increased torque or deterioration of mechanical parts.
Bearing, gear and other mechanical parts:
Oil seal:
Note: When the output shaft oil seal is exposed to a large amount of water at one time,
water may enter the gear case. Always drain the water circuit before removing the
auger for service.

4. CONDENSER (AIR-COOLED MODEL ONLY)

Check the condenser once a year, and clean if required by using a brush or vacuum cleaner.
More frequent cleaning may be required depending on the location of the icemaker.

5. AIR FILTER (AIR-COOLED MODEL ONLY)

Plastic mesh air filters remove dirt or dust from the air, and keep the condenser from getting
clogged. If the filters get clogged, the icemaker's performance will be reduced. Remove and
clean the air filters at least twice per month:
1) Slide the air filter off the louver.
2) Clean the air filter by using a vacuum cleaner. When severely clogged, use warm water
and a neutral cleaner to wash the air filter.
3) Rinse and dry the air filter thoroughly, and place it in position.
