Operation
Cleaning and preventive maintenance (all models)
Note: Do not use bleach to sanitize or clean the ice machine.
Preventive maintenance
Periodic cleaning of Follett’s ice machine system is required to ensure peak performance and delivery of clean,
sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as
recommended, and more often if environmental conditions dictate.
Cleaning of the condenser can usually be performed by facility personnel. Cleaning of the ice machine system,
in most cases, should be performed by your facility’s maintenance staff or a Follett authorized service agent.
Regardless of who performs the cleaning, it is the operator’s responsibility to see that this cleaning is performed
according to the schedule below. Service problems resulting from lack of preventive maintenance will not be
covered under the Follett warranty.
Weekly exterior care
The exterior may be cleaned with a stainless cleaner such as 3M Stainless Steel Cleaner & Polish or equivalent.
Monthly condenser cleaning (air-cooled ice machine only)
1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled ice machines to
ensure
optimal performance.
2. When reinstalling counter panels in front of remote ice machines, be sure that ventilation louvers line up
with condenser air duct.
Semi-annual evaporator cleaning (every 6 months)
WARNING
§Wear rubber gloves and safety goggles (and/or face shield) when handling ice machine cleaner or sanitizer.
CAUTION
§Use only Follett approved SafeCLEAN™ Cleaner (part #00132001) and NU-CALGON IMS-II SANITIZER.
§Do not mix Cleaner and Sanitizer solutions together.
§DO NOT USE BLEACH.
§It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling.
§Read and understand all labels printed on packaging before use.
Note: Complete procedure for cleaning an sanitizing MUST be followed. Ice must be collected for
10minutes before putting ice machine back into service.
1. To clean – Remove cover. Press the CLEAN
button. The machine will drain. Wait for the LO
WATER light to come on (Fig. 1).

8. Using disposable food service grade gloves,
insert dry Sani-Sponge™ (kit part# 00132068).
Next, insert Sani-Sponge soaked in Nu-Calgon
IMS-II sanitizer solution (from Step 5). Push
both Sani-Sponges down ice transport tube
with supplied pusher tube(Fig.8).
9. Remove and discard 16" (407mm) pusher tube
(Fig. 9).
10. Reconnect coupling. When sanitizing cycle
ends, machine will start producing ice. Press
power switch ON. Ice pushes Sani-Sponges
through tube (Fig. 10).
