2. Maintenance
IMPORTANT
1. This icemaker must be maintained individually, referring to the instruction
manual and labels provided with the icemaker.
2. To have the optimum performance of this icemaker, the following
consumable parts need periodic inspection, maintenance and replacement:
Extruding Head
Housing
Gear Motor
Auger
Mechanical Seal
These parts should be inspected at least once a year or every 10,000 hours of
operation. Their service life, however, depends on water quality and
environment. More frequent inspection and maintenance are recommended.
Consult with your local distributor about inspection and maintenance service.
To obtain the name and phone number of your local distributor, call Hoshizaki
Care at 1-800-233-1940 in the USA.
1) Stainless Steel Exterior
To prevent corrosion, wipe the exterior occasionally with a clean and soft cloth. Use a
damp cloth containing a neutral cleaner to wipe off oil or dirt build up.
2) Storage Bin and Scoop
• Wash your hands before removing ice. Use the plastic scoop provided (accessory).
• The storage bin is for ice use only. Do not store anything else in the bin.
• Keep the scoop clean. Clean using a neutral cleaner and rinse thoroughly.
• Clean the bin liner using a neutral cleaner. Rinse thoroughly after cleaning.
