A. Cleaning and Sanitizing Instructions
Hoshizaki recommends cleaning and sanitizing this unit at least twice a year. More
frequent cleaning and sanitizing, however, may be required in some existing water
conditions.
WARNING
1. To prevent injury to individuals and damage to the icemaker, do not use
ammonia type cleaners.
2. Carefully follow any instructions provided with the bottles of cleaning and
sanitizing solution.
3. Always wear liquid-proof gloves and goggles to prevent the cleaning and
sanitizing solutions from coming into contact with skin or eyes.
4. Do not use ice made from the cleaning and sanitizing solutions. After cleaning
and sanitizing, be careful not to leave any solution on the parts or in the
storage bin.
1. Water System
a) Cleaning Solution
Dilute 9.6 fl. oz. (0.29 l) of Hoshizaki "Scale Away" with 1.6 gal. (6.0 l) of warm water.
b) Cleaning Procedure
1) Close the icemaker water supply line shut-off valve.
2) Move the control switch to the "DRAIN" position. See Fig. 7. Allow the water system to
drain for 5 minutes.
3) Move the dispense mode switch to the "CONTINUOUS" position, then dispense all of
the ice from the storage bin.
Note: Ice dispenses continuously for a maximum of 60 seconds per activation.
4) Move the control switch to the "OFF" position, then turn off the power supply. Remove
the front and top panels, then move the power switch to the "OFF" position.
5) Remove the storage bin cover. Remove spout B, then remove spout A.
6) Pour the cleaning solution over the extruding head until the evaporator assembly and
the reservoir are full and the solution starts to overflow into the drain pan.
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
solution over the extruding head until the evaporator assembly is completely full.
7) Replace spout A, spout B, and the storage bin cover in their correct positions.
8) Allow the icemaker to sit for 10 minutes before operation. If you placed a clamp on the
reservoir hose in step 6, remove it before operation.
