Operation
Cleaning/sanitizing and preventive maintenance (all models)
Note: Do not use bleach to sanitize or clean the icemaker.
Preventive maintenance
Periodic cleaning of Follett’s icemaker 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 icemaker 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 icemaker only)
1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemakers to ensure
optimal performance.
2. When reinstalling counter panels in front of remote icemakers, 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 Plus™ cleaning solution.
• 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 and sanitizing MUST be followed. Ice must be collected for
10minutes before putting ice machine back into service.

Evacuation
Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close all valves. Allow the
system to sit for approximately 20 minutes. During this period the system pressure should not rise. If the system
pressure rises and stabilizes there is moisture in the system and further evacuation is needed. If the pressure
continues to rise check the system for leaks.

Ice capacity test
Ice machine production capacity can only be determined by weighing ice produced in a specic time period.
1. Replace all panels on ice machine.
2. Run ice machine for at least 15 minutes.
3. Move TDS switch to LOW.
4. Press the reset button on the board.
5. Weigh and record weight of container used to catch ice.
6. Catch ice for 15 minutes.
7. Weigh harvested ice and record total weight.
8. Subtract weight of container from total weight.
9. Convert fractions of pounds to decimal equivalents (ex. 6 lbs 8 oz = 6.5 lbs).
10. Calculate production using following formula:
1440 min. x wt. of ice produced
Total test time in minutes
Production capacity/24 hr.
=
11. Calculated amount per 24 hours should be checked against rated capacity for same ambient and water
temperatures in Ice Production Tables.
12. Move TDS switch to the HI TDS position.
