Section 3 Operation Ice Making Sequence of Operation Control Board Timers The power button must be depressed and the water curtain/ice dampers must be in place on the evaporator before the ice machine will start. The control board has the following nonadjustable timers: • The ice machine control board will set its own install date after 100 freeze and harvest cycles. • The ice machine is locked into the freeze cycle for 6 minutes before a harvest cycle can be initiated.
Operation Safe Operation Mode Allows the ice machine to operate up to 72 hours if the ice thickness probe and/or water level probe sensors fail. • When the control board starts the safe mode, an alert is flashed on the display to notify the end-user they have a production problem. • The control board automatically initiates and monitors the safe mode. The control will automatically exit the safe mode if a normal signal is received from the input.

Section 4 Maintenance Descaling and Sanitizing General You are responsible for maintaining the ice machine in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty. Descale and sanitize the ice machine every six months for efficient operation. If the ice machine requires more frequent descaling and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment.
Maintenance Section 4 ,Caution Use only Manitowoc approved Ice Machine Cleaner/De-scaler and Sanitizer for this application (Manitowoc Cleaner/De-scaler part number 9405463 and Manitowoc Sanitizer part number 9405653). 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 bottles before use. Detailed Descaling and Sanitizing Procedure Ice machine cleaner/descaler is used to remove lime scale and mineral deposits.
Section 4 Maintenance Step 4 Wait until the cycle is complete (approximately 24 minutes). Then disconnect power to the ice machine (and dispenser when used). nWarning Disconnect the electric power to the ice machine at the electric service switch box. Step 5 Remove parts for descaling. Notice Refer to parts removal page 47. Continue with Step 6 when the parts have been removed. Step 6 Mix a solution of cleaner/descaler and lukewarm water.
Maintenance Section 4 Step 11 Use half of the sanitizer/water solution to sanitize all food zone surfaces of the ice machine and bin (or dispenser). Use a spray bottle to liberally apply the solution. When sanitizing, pay particular attention to the following areas: • Side walls • Base (area above water trough) • Evaporator plastic parts - including top, bottom and sides • Bin or dispenser Do not rinse the sanitized areas.
Section 4 Maintenance Parts Removal for Detailed Descaling and Sanitizing Single evaporator is shown; Each evaporator will have a distribution tube and water curtain/damper. A. Remove the water curtain(s) • Gently flex the curtain in the center and remove it from the right side. • Slide the left pin out. B. Remove the ice thickness probe • Compress the hinge pin on the top of the ice thickness probe. • Pivot the ice thickness probe to disengage one pin then the other.
Maintenance Section 4 Remedial Cleaning Procedure This procedure descales all components in the water flow path, and is used to descale the ice machine between the bi-yearly detailed descaling and sanitizing procedure. Ice machine cleaner/descaler is used to remove lime scale and mineral deposits. Ice machine sanitizer disinfects and removes algae and slime. NOTE: Although not required and dependent on your installation, removing the ice machine top cover may allow easier access.
Section 4 Maintenance Cleaning the Air Filter and Condenser Removal from Service/Winterization The washable filter on self-contained ice machines is designed to catch dust, dirt, lint and grease. Clean the filter once a month with mild soap and water. A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life. All Models 1. Descale and sanitize the ice machine. 2.
