Section 4 Maintenance

Part Number 000005544 12/09 4-5

CLEANING PROCEDURE

Ice machines that are heavily scaled or have not been cleaned on a regular basis will need to run the Heavily Scaled

Cleaning Procedure before this one. Failure to do so may result in binding of the auger as the lime scale releases

from the auger and evaporator barrel.

Ice machine cleaner is used to remove lime scale or other mineral deposits. It is not used to remove algae or slime.

Refer to the “Sanitizing Procedure” for removal of algae and slime.

Step 1 Remove panels and set the ICE/OFF/CLEAN

toggle switch to the OFF position

Step 2 Turn off the water supply to the ice machine.

Step 3 Remove all ice from the bin.

Step 4 Place ICE/OFF/CLEAN toggle switch in the

CLEAN position. The dump valve will open and drain the

water from the evaporator and reservoir.

Step 5 Wait approximately 30 seconds (or until the

evaporator is drained) and place the toggle switch in the

OFF position.

Step 6 Refer to chart and premix the correct solution of

cleaner and cool water for your ice machine

Step 7 Remove the top cover from the ice chute and

pour the cleaner/water solution into the evaporator. Add

the entire amount of premixed solution (excess solution

will exit through the overflow tube in the water

reservoir).

Step 8 Replace the ice chute cover and allow the ice

machine to stand for 30 minutes.

Step 9 Turn on the water supply to the ice machine.

Step 10 Move the toggle switch to the ICE position.

After the 15 minute delay period expires the compressor

will energize and produce ice with the cleaning solution.

Step 11 The ice machine will freeze and discharge the

cleaning solution into the bin. Allow the cycle to run for

15 minutes.

Step 12 Place the toggle switch in the OFF position

and refer to sanitizing procedure.

NOTE: Discard all ice produced during the cleaning

process. Cleaning and sanitizing must be performed on

adjacent surface areas not contacted by the water

distribution system. Refer to Removal of Parts for

Cleaning/Sanitizing (Page 4-7)- Disassemble, clean and

sanitize the ice machine a minimum of once every six

months.
