Sanitizing and Cleaning

It is the USER’S RESPONSIBILITY to keep the ice machine and ice storage bin in a sanitary condition. Without human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. That chemical dissolves mineral build up that forms during the ice making process. Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and sanitized. Note: Maintenance and Cleaning should be

scheduled at a minimum of twice a year.

ICE MAKING SYSTEM: In place cleaning.

1.Check and clean any water treatment devices, if any are installed.

2.Remove screws, and the front and top panel.

3.Move the ON-OFFswitch to OFF.

4.Remove all the ice from the storage bin.

5.Remove the cover from the water reservoir and block up the float.

6.Drain the water reservoir and freezer assembly using the drain tube attached to the freezer water inlet. Return the drain tube to its normal upright position and replace the end cap.

7.Prepare the cleaning solution: Mix eight (8) ounces of ice machine cleaner with three (3) quarts of hot water. The water should be between 90-115°F.

8.Slowly pour the cleaning solution into the water reservoir until full. Wait 15 minutes, then switch the master switch ON.

9.As the ice machine begins to use water form the reservoir, continue to add more cleaning solution to maintain a full reservoir.

10.After all of the cleaning solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch to OFF.

11.After draining the reservoir, as in step 6, wash and rinse the water reservoir.

12.Go thru steps 13-18 to sanitize the ice machine water system.

13.Mix two (2) gallons of sanitizer solution. Use an approved sanitizer. A possible sanitizer solution may be obtained by mixing two (2) gallons of warm (90-115°F.) potable water with one (1) ounce of bleach.

14.Slowly pour the sanitizer solution into the water reservoir until the float rises, then switch the master switch ON.

15.As the ice machine uses water from the reservoir, continue to pour the sanitizer solution into the reservoir.

16.After half (1/2) of the sanitizer solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch OFF.

17.Drain the reservoir and thoroughly wash the interior of the reservoir and cover with sanitizer solution.

18.Remove the block from the float in the water reservoir.

19.Switch the master switch to ON.

20.Continue ice making for at least 15 minutes, to flush out any cleaning solution. Switch the master switch OFF.

Note: DO NOT USE any ice produced from the cleaning solution! Be sure no ice remains in the bin!

21.Remove and discard all ice from the storage bin.

22.Add warm water to the ice storage bin and thoroughly wash and rinse all surfaces within the bin.

23.Sanitize the bin interior by thoroughly washing the interior of the bin and bin door with the balance of the sanitizing solution.

24.Switch the master switch ON.

25.Replace the panels.

Warning! Ice machine cleaner contains acids. If swallowed, DO NOT induce vomiting. Give large amounts of water or milk. Call Physician immediately. In case of external contact, flush with water.
