CLEANING & 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.

 
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 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, except use an approved
sanitizing solution in place of the cleaning solution.
A possible sanitizing solution may be made by
mixing  1 ounce of household bleach to 2 gallons
of warm (95

o

F. to 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 interior with an approved
sanitizer using the directions for that sanitizer.
18. Replace the front panel.

Scotsman Ice Machine
Cleaner contains acids.
These compounds may
cause burns. 
 
If swallowed, DO NOT
induce vomiting.  Give
large amounts of water
or milk.  Call Physician
immediately.  In case of
external contact, flush
with water.  
KEEP OUT OF THE
REACH OF CHILDREN.
