Page 26 Cooling Tower Applications A water cooling tower installation does not require modification of the ice machine. The water regulator valve for the condenser continues to control the refrigeration discharge pressure. It is necessary to know the amount of heat rejection, and pressure drop through the condenser and water valves (inlet and outlet) when using a cooling tower on an ice machine.
Page 27 Electrical Service Warning All wiring must conform to local, state and national codes. VOLTAGE The maximum allowable voltage variation is ± 10% of the rated voltage on the ice machine model/serial number plate at compressor start-up. FUSE/CIRCUIT BREAKER A separate fuse/circuit breaker must be provided for each ice machine.

Page 29 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.

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.

Page 175 FILTER-DRIERS The size of the filter-drier is important. The refrigerant charge is critical. Using an improperly sized filter-drier will cause the ice machine to be improperly charged with refrigerant. Important Driers are covered as a warranty part. The drier must be replaced any time the system is opened for repairs.
