Icemaker cleaning & sanitizing
Periodic cleaning of Follett's icemaker system is required
to ensure peak performance and delivery of clean,
sanitary ice. The following cleaning procedures should be
performed at least as frequently as recommended, and
more often if environmental conditions dictate.
• To reduce risk of electrical shock disconnect
power before servicing
• Wear rubber gloves and safety goggles (and/
or face shield) when handling ice machine
cleaner or sanitizer mixtures
• Use only Follett approved cleaners (see procedure below)
• It is a violation of Federal law to use these solutions in a
manner inconsistent with their labeling
• Read and understand all packaging instructions before use
• Do not use solvents, abrasive cleaners, metal scrapers or
sharp objects to clean any part of the dispenser
