Cleaning and Sanitizing the Interior
An in place cleaning/sanitizing procedure should be
performed every six (6) months.

chemical usage is not covered by the warranty.

(part #7013400) and sanitizer (part #7013401).
In Place Cleaning / Sanitizing - This procedure
allows semi-annual in place cleaning and sanitizing of
the interior. The quality of the homes potable water
supply may call for more frequent cleaning intervals.
Use ice machine cleaner (#7013400) to remove lime
scale or other mineral deposits. Ice machine sanitizer
(#7013400) disinfects and removes algae and slime.
WEAR RUBBER GLOVES AND SAFETY GOGGLES
(AND/OR FACE SHIELD) WHEN HANDLING ICE
MACHINE CLEANER OR SANITIZER.
NOTE: Before beginning, removed all ice from the bin.

cleaner (7013400 only) in a container that will fit
easily under lifted paddles (See Figure 4-4).
2. Press CLEAN button (See Figure 4-2). The ice
machine will initiate a 2 minute harvest to remove
