[a]CLEANING PROCEDURE

1)Dilute 16 fl. oz. of the recommended cleaner Hoshizaki “Scale Away” or “LIME-A-WAY” (Economics Laboratory, Inc.) with 3 gallons of 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 on after 3 minutes. The defrost cycle starts and the cubes will be removed from the Evaporator.

3)Turn off the power supply.

4)Remove the Front Panel and then remove the Insulation Panel.

5)Remove the Base Cover.

6)Drain the Water Tank by removing one end of the Pump Tubing. See Fig. 4.

7)After tank has drained, replace the removed parts in their correct positions.

8)Pour the cleaning solution into the Water Tank.

9)Fully open the Cleaning Valve on the left side wall of the machine compartment.

10) Move the Control Switch, on the Control Box, to the “WASH” position.

11) Replace the Insulation Panel and the Front Panel in their correct positions.

12)Turn on the power supply, and start the washing process.

13)Turn off the power supply after 30 minutes.

14)Remove the Front Panel and the Insulation Panel.

15)Drain the Water Tank. (See the above step 6).

16)Replace the tubing and the Insulation Panel in their correct positions.

17)Move the Control Switch to the “ICE” position.

18)Close the Cleaning Valve.

Note: The icemaker will not operate unless the Cleaning Valve is completely closed.

19)Replace the Front Panel in its correct position. 63
