Inspection And Maintenance; Before Calling For Service - Hoshizaki FM-150KE Instruction Manual

ENGLISH
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.
After cleaning, be sure to place the air filter back in position.

2. INSPECTION AND MAINTENANCE

To achieve optimum icemaker performance, the following parts need periodic inspection and maintenance:
Extruding head (upper bearing)
Housing (lower bearing)
Mechanical seal
These parts should be inspected after two years from installation or 10,000 hours of operation, whichever comes first, and once
a year afterwards. Replacement of these parts is required if wear exceeds factory recommendations.
Their service life, however, depends on water quality and environment. More frequent inspection and maintenance are
recommended in bad or severe water conditions.
Consult with your local Hoshizaki service agent about inspection and maintenance service.
