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 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.
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 (P/N 0132001) and NU-CALGON IMS-II or IMS-III
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.
