CLEANING and SANITIZING
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.
Sanitizing of the ice storage bin should be scheduled for a minimum of 4 times a 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. Remove screws and remove the upper front
panel.
3. Move the ON-OFF switch to OFF.
4. Remove the cover to the ice storage bin, and
remove the ice.
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 water should be between
90-115 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, only use an approved
sanitizing solution in place of the cleaning
solution. A possible sanitizing solution to use could
be 1 ounce of household bleach mixed with 2
gallons of warm (95
o
F. - 115
o
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 cover, dispensing vane, bin
bottom, and interior with an approved sanitizer
using the directions for that sanitizer.
18. Replace the ice storage bin cover, and the
front panel.
