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 "OFF" position, pause momentarily, then move to the "DRAIN" position. See Fig. 9. Allow the water system to drain for 5 minutes.

Note: a) A momentary pause in the "OFF" position is necessary to de-energize the control board when moving the control switch between "ICE" and "DRAIN."

Otherwise there is a delay of several minutes before the new selection takes effect.

b)If the control switch is left in the "DRAIN" position for 10 minutes or more, a

2-beep alarm sounds every 5 seconds. Move the control switch out of the

"DRAIN" position to clear the alarm.

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.
