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. Read and understand all labels printed on bottles before use.
RF/RFS/RNS MODELS CLEANING/SANITIZING PROCEDURES Cleaning/Sanitizing Procedure This procedure must be performed once every month. • All ice must be removed from the bin • The ice machine and bin must be disassembled cleaned and sanitized • The ice machine produces ice with the cleaner and sanitizer solutions • All ice produced during the cleaning and sanitizing procedure must be discarded Procedure to Clean/Sanitize Use Ice Machine Cleaner part number 000000084.
Step 6 Fill the evaporator and reservoir with cleaning solution. Prop Float Up to Prevent Low Water Level Shutdown 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. The ice machine will discontinue the cleaning cycle if the water float switch opens.
Step 9 Place the toggle switch in the OFF position. Step 10 Refer to disassembly for cleaning/sanitizing and remove parts for hand cleaning/sanitizing. • Hand clean all parts • Rinse all parts with clear potable water • Sanitize all parts - do not rinse after sanitizing • Spray all interior bin surfaces with sanitizer (do not rinse sanitized areas). • Spray evaporator discharge spout Step 11 Reassemble ice machine. Step 12 Turn off the ice making water supply.
Step 13 Refer to chart and premix water and sanitizer. Amount of Water Amount of Sanitizer 1 Gallons (4 L) Water 1/2 ounce (15 ml) Step 14 Fill the evaporator and reservoir with sanitizer/water solution. Step 15 Move the toggle switch to the ON position. The ice machine will make ice with the sanitizer/water solution and deposit the ice in the bin. Add the remaining sanitizer/water solution when the water level in the reservoir drops.
Heavily Scaled Cleaning Procedure Perform this procedure if you have some or all of these symptoms. • Excessive grinding, popping or squealing noises from the evaporator • Grinding noise from gearbox • Ice machine trips speed sensor NOTE: A Cleaning/Sanitizing Procedure must be performed after this procedure. Procedure to Clean Heavily Scaled Flake Ice Machines Step 1 Remove front and top covers and set the toggle switch to the OFF position. Step 2 Remove all ice from the bin.

After the rotation speed sensor verifies 10 minutes of correct rotation the time delay ends and the liquid line and suction solenoid valves energize.
RN0400 Self-Contained Air-cooled & Water-Cooled NOTE: Ice machines use an auger to remove ice from the evaporator. Occasional noises (creaks, groans, squeaks, or pops) are a normal part of the ice making process. Operation The ice machine will not start until: A. The compressor rocker switch is moved to “ON”. B. Ice does not contact the bin thermostat bulb. C. The water reservoir is full of water.
RN1000/RN1400 Self-Contained Air-Cooled & Water-Cooled NOTE: Ice machines use an auger to remove ice from the evaporator.

The transport tube shuttle switch is closed. C. The water reservoir is full of water. Placing the toggle switch in the ON position starts the gear motor and refrigeration system.
RN1000C/RN1200C QuietQube Remote Air-cooled Model with Remote Condensing Unit NOTE: Ice machines use an auger to remove ice from the evaporator. Occasional noises (creaks, groans, squeaks, or pops) are a normal part of the ice making process. Operation The ice machine will not start until: A. The rocker switch is moved to ON. B. The transport tube switch is closed. C. The water reservoir is full of water.
Ice Production/Quality Check QUALITY CHECK Ice quality varies with ambient and water temperatures, and is measured by the amount of water in the ice. Generally speaking, higher incoming water temperature results in lower ice quality. Lower water temperature results in higher ice quality. ICE PRODUCTION CHECK NOTE: Ice production checks that are within 10% of the charted capacity are considered normal due to variances in air and water temperatures. Actual temperatures will seldom match the chart exactly. 1.
Thermostat Settings Bin Thermostat: The bin thermostat sensing bulb is located in the ice chute on modular models and in the bin thermostat holder on the right side of the bin on self storage models. The bin thermostat turns the ice machine on and off as the level of ice in the bin changes. Use the initial setting from the chart and adjust as required.
Troubleshooting Electrical Flowcharts Diagnostic troubleshooting for the ice machine involves following flowcharts that are dependant on symptoms of the failed machine. Follow the flowcharts for the failure symptom and model you are working on. NOTE: Refer to the sequence of operation to determine where in the sequence the ice machine has failed. An example would be an ice machine that energizes the gear motor, but the compressor does not energize.

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. SUCTION CLEANUP FILTER-DRIER Contaminated systems must have a suction line filterdrier installed to remove contamination.
TOTAL SYSTEM REFRIGERANT CHARGE Important This information is for reference only. Refer to the ice machine serial number tag to verify the system charge.

Charts Ice Production & Refrigerant Pressure These charts are used as guidelines to verify correct ice machine operation. Accurate collection of data is essential to obtain the correct diagnosis. • Zero out manifold gauge set before obtaining pressure readings to avoid misdiagnosis. • Discharge and suction pressure are highest at the beginning of the cycle. Allow system to stabilize for a minimum of 10 minutes, then verify the pressures are within the range indicated.
