III. Cleaning and Maintenance
CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after any cleaning or maintenance is done to the unit. Make
sure that none have fallen into the storage bin.
A. Cleaning and Sanitizing Instructions
Hoshizaki recommends cleaning and sanitizing this unit at least once a year. More
frequent cleaning and sanitizing, however, may be required in some existing water
conditions.
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. To prevent damage to the water pump seal, do not operate the icemaker with
the control switch in the "WASH" position when the water tank is empty.
1. Cleaning Procedure
1) Dilute 16 fl. oz. (473 ml) of Hoshizaki "Scale Away" with 3 gal. ( 11 l) of warm water.
2) Remove all ice from the evaporator and the storage bin.
Note: To remove cubes on the evaporator, turn off the power supply and turn it back on
after 3 minutes. The harvest cycle starts and the cubes will be removed from the
evaporator.
3) Turn off the power supply.
4) Remove the front panel, then remove the insulation panel by lifting up the panel slightly
and pulling it towards you.
5) Remove the base cover, then disconnect one end of the pump tubing to drain the water
tank. See Fig. 13. After the water tank has drained, reconnect the pump tubing.
6) In bad or severe water conditions, clean the float switch assembly as described below.
Otherwise, continue to step 7.
a. Disconnect the vent tube and the flush tube from the top of the float switch, then
remove the float switch assembly. Remove the rubber boot from the bottom of the
assembly.
b. Remove the retainer rod from the bottom of the float switch housing, then remove
the float. Be careful not to bend the retainer rod excessively when removing it.
c. Wipe down the float switch assembly's housing, shaft, float, and retainer rod with
cleaning solution. Clean the inside of the rubber boot and hose with cleaning
solution. Rinse the parts thoroughly with clean water.
d. Reassemble the float switch assembly and replace it and the rubber boot in their
correct positions. Reconnect the vent tube and the flush tube.
