III. Cleaning and Maintenance
IMPORTANT
Ensure all components, fasteners and thumbscrews are securely in place after
any maintenance or cleaning is done to the equipment.
WARNING
1. Hoshizaki recommends cleaning this icemaker at least twice a year.
More frequent cleaning, however, may be required in some existing water
conditions.
2. To prevent injury to individuals, do not use any ammonia type cleaners.
3. Carefully follow any instructions provided with the bottles of cleaning and
sanitizing solution.
4. Always wear liquid-proof gloves to prevent the cleaning and sanitizing
solutions from coming into contact with skin.
5. Never run the icemaker when the reservoir is empty.
6. After cleaning, do not use ice made from the cleaning and sanitizing
solutions. Be careful not to leave any solution in the storage bin.
A. Cleaning and Sanitizing Instructions - Water System
1. Cleaning Solution
Dilute approximately 9.6 fl. oz. (0.29 l) of Hoshizaki "Scale Away" with 1.6 gallons (6.0 l) of
warm water.
2. Cleaning Procedure
1) Close the water supply line shut-off valve.
2) Move the dispense mode switch to the "CONTINUOUS" position.
3) Activate the dispense sensor to remove the ice from the storage bin.
4) Move the control switch to the "DRAIN" position, and wait about 15 minutes for the
water system to drain.
5) Move the control switch to the "OFF" position. Remove the upper front, top and left side
panels.
6) Move the power switch to the "OFF" postion. Unplug the icemaker from the electrical
outlet.
7) Disconnect the ice transport hose from the spout, and pour the cleaning solution into
the ice transport hose. Be careful not to overfill the reservoir. Reconnect the transport
hose.
Note: If there is excess scale on the extruding head, fill the evaporator assembly and
reservoir as described above, then use a clamp on the reservoir hose between
the reservoir and evaporator assembly to block flow. Pour additional cleaning
fluid into the transport hose until the evaporator assembly is completely full.
Reconnect the transport hose.
