CLEANING and SANITATION

A Scotsman Ice System represents a sizable investment of time and money in any company’s business. In

order to receive the best return for that investment, it MUST receive periodic maintenance.

It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. It is always preferable, and

less costly in the long run, to avoid possible down time by keeping it clean; adjusting it as needed; and by

replacing worn parts before they can cause failure. The following is a list of recommended maintenance

that will help keep the machine running with a minimum of problems.

Maintenance and Cleaning should be scheduled at a minimum of twice per year.

Electrical power will be ON when doing in place

cleaning.

ICEMAKING SYSTEM: In place cleaning

1. Check and clean any water treatment devices, if

any are installed.

2. Pull out and remove the front panel.

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.

To Sanitize:

Repeat steps 8-11, except substitute an approved

sanitizing solution for the cleaning solution. A

possible sanitizing solution may be made by mixing

1 ounce of household bleach with 2 gallons of

warm (95

0

F. - 115

0

F.) water.

12. Remove the block from the float in the water

reservoir.

13. Switch the master switch to ON

14. Continue ice making for at least 15 minutes, to

flush out any cleaning solution. Check ice for acid

taste - continue icemaking until ice tastes sweet.

DO NOT USE any ice produced from the cleaning

solution.

Be sure no ice remains in the bin.

15. Remove all ice from the storage bin.

16. Add warm water to the ice storage bin and

thoroughly wash and rinse all surfaces within the

bin.

17. Sanitize the bin interior with an approved

sanitizer using the directions for that sanitizer.

18. Replace the front panel.
