Page 29: Maintenance
Maintenance procedures covered in this manual are not covered by the warranty. Caution Use only Manitowoc approved Ice Machine Cleaner (part number 000000084) and Sanitizer (part number 9405653). Do not mix Cleaner and Sanitizer solutions together. It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling.
Page 30 Procedure to Clean/Sanitize Use Ice Machine Cleaner part number 000000084. Use Ice Machine Sanitizer part number 9405653. Step 1 Remove front and top covers and set the toggle switch to the OFF position. Step 2 Remove all ice from the bin. Step 3 Turn off the ice making water supply and drain water from evaporator and reservoir.
Page 31 Step 7 Move the toggle switch to the ON position. The ice machine will make ice with the cleaning solution and deposit the ice in the bin. Add the remaining cleaner/ water solution as the water level in the reservoir drops. NOTE: Do not allow the cleaner/water level to drop below the minimum water level.

CONTROL BOARD ERRORS The control board monitors the following: Low water Gear motor amperage High pressure Clogged drain There are two different errors - Soft errors and hard errors. • Soft errors can be reset by cycling power on/off. • Hard errors can not be cleared by cycling power on/ off and must be reset by pressing the control board reset button.
Page 141 HI AMPS - GEAR MOTOR AMPERAGE EXCEEDS 3.8 AMPS Soft Error The control board stops the ice machine, energizes the Hi Amps & Service lights and initiates a time delay period. The ice machine will restart after the 60 minute delay. The ice machine continues to run if amperage remains below 3.8 amps for six hours.
