1. Water System

a)Cleaning Solution

Dilute 9.6 fl. oz. (0.29 l) of recommended cleaner, Hoshizaki "Scale Away" or "LIME-A- WAY" (Economics Laboratory, Inc.), with 1.6 gal. (6.0 l) of warm water.

b)Cleaning Procedure

1)Close the water supply line shut-off valve.

2)Move the dispense mode switch to the "CONTINUOUS" position, then dispense all of the ice from the storage bin.

3)Move the control switch to the "DRAIN" position and allow the water system to drain for 5 minutes.

Note: If the unit is running, the drain valve will not open until 2.5 minutes after the control switch is moved to the "DRAIN" position. This allows the components to cycle down.

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 front cover of the storage bin. Remove spout B, then remove spout A. See Fig. 6.

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 fluid over the extruding head until the evaporator assembly is completely full.

7)Replace spout A, spout B, and the front cover of the storage bin in their correct positions.

8)Allow the icemaker to sit for about 10 minutes before operation. If you placed a clamp on the reservoir hose in step 6, remove it before operation.

9)Move the power switch to the "ON" position and replace the panels in their correct positions. Turn on the power supply, then move the control switch to the "ICE" position. Make ice using the solution until the icemaker stops making ice.

Note: This unit will not run without the front panel in position.

10)Move the control switch to the "DRAIN" position and allow the solution to drain for 5 minutes.

11)Move the control switch to the "ICE" position. Open the water supply line shut-off valve to supply water to the reservoir.

12)After the gear motor starts, move the control switch to the "DRAIN" position and allow the water system to drain for 5 minutes.

Note: If you do not sanitize the unit, move the control switch to the "ICE" position after the water system drains. Allow the icemaker to run for about 30 minutes, then move the control switch to the "OFF" position. Turn off the power supply, then remove the front panel and front cover of the storage bin. Go to step 12 in "IV. A.2.c) Cleaning and Sanitizing Procedure."
