MAINTENANCE 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 cods require, and every time the ice machine is

cleaned and sanitized.

The ice machine’s water system should be

cleaned and santized a minimum of twice per

year.
ICE MAKING SYSTEM: In place cleaning

1. Check and clean any water treatment devices, if

any are installed.
2. Remove screws and front and top panels.
3. Move the ON-OFF switch to OFF.
4. Remove all the ice from the storage bin.
5. Remove the cover to the water reservoir and

block the float up.
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 ounces

of Scotsman Ice Machine Cleaner with three quarts

of hot water. The solution should be between 90

and 115 degrees F.

8. Slowly pour the cleaning solution into the water

reservoir until it is full. Wait 15 minutes, then

switch the master switch to ON.
9. As the ice maker begins to use water from 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 13-19 to sanitize the ice machine

water system.
13. Mix two gallons of sanitizer solution. Use an

approved sanitizer.
A possible sanitizer solution may be obtained by

mixing two gallons of warm (90-115

o

F.) potable

water with 1 ounce of household bleach.
14. Slowly pout 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

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. Be sure the drain hose is upright and

capped.
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.

DO NOT USE any ice produced from the

cleaning solution. Be sure no ice remains in

the bin.

21. Remove 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 washing the interior

of the bin with the balance of the sanitizer solution.
24. Switch the master switch ON.
25. Return all panels to their original positions.
