1. HOSHIZAKI recommends cleaning this unit at least once a year. More
frequent cleaning, however, may be required in some existing water con­ditions.

2. To prevent injury to individuals and damage to the icemaker, do not use
ammonia type cleaners.

3. Always wear liquid-proof gloves for safe handling of the cleaning and sani­tizing solution. This will prevent irritation in case the solution comes into
contact with the skin.

IMPORTANT

1. The Cleaning Valve is used to provide access to the inside of the Evapora­tor during the cleaning and sanitizing operation. It should be closed for
all icemaking operation. The Compressor will not operate unless this
valve is completely closed.

2. To open the Cleaning Valve, the Valve Handle should be parallel to the
valve body. To close the valve, the Valve Handle should be at a right
angle to the valve body.

2. MAINTENANCE

This icemaker must be maintained individually, referring to the instruction
manual and labels provided with the icemaker.

1) Stainless Steel Exterior

To prevent corrosion, wipe the exterior occasionally with a clean, 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 (Bin
Accessory).

• The Storage Bin/Dispenser Unit is for ice use only. Do not store anything else in
the Bin/Dispenser.

IMPORTANT

• Keep the Scoop clean. Clean it by using a neutral cleaner and rinse thoroughly.

• Clean the bin/Dispenser liner by using a neutral cleaner. Rinse thoroughly after

cleaning.

3) Air Filter (Air-cooled models only)

A plastic mesh air filter removes dirt or dust from the air, and keeps the Condenser
from getting clogged. As the Filter gets clogged, the icemaker’s performance will be
reduced. Check the Filter at least twice a month. When clogged, use warm water
and a neutral cleaner to wash the Filter.

4) Condenser (Except Water-cooled models)

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.
