WARNING If you do not understand the procedures or the safety precautions that must be followed, call your local Manitowoc service representative to perform the maintenance procedures for you.
Maintenance Section 4 Interior Cleaning and Sanitizing 2. Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Clean from top to bottom not side to side. Be careful not to bend the condenser fins. 3. Shine a flashlight through the condenser to check for dirt between the fins. If dirt remains: A. Blow compressed air through the condenser fins from the inside. Be careful not to bend the fan blades. B. Use a commercial condenser coil cleaner.
Section 4 Maintenance CLEANING PROCEDURE Ice machine cleaner is used to remove lime scale or other mineral deposits. It is not used to remove algae or slime. Refer to “Sanitizing Procedure” for removal of algae and slime. Step 1 Set the toggle switch to the OFF position after ice falls from the evaporator at the end of a Harvest cycle. Or, set the switch to the OFF position and allow the ice to melt off the evaporator. CAUTION Never use anything to force ice from the evaporator. Damage may result.
Maintenance Section 4 REMOVAL OF PARTS FOR CLEANING/SANITIZING WARNING Disconnect electric power to the ice machine at the electric switch box before proceeding. 1. Turn off the water supply to the ice machine at the water supply valve. 2. Remove the parts or components you want to clean or sanitize. See the following pages for removal procedures for these parts. WARNING Wear rubber gloves and safety goggles (and/or face shield) when handling Ice Machine Cleaner or Sanitizer. 3.

Section 4 Maintenance Water Treatment/Filtration GENERAL Local water conditions may require the installation of a water treatment system to inhibit scale formation, filter out sediment, remove chlorine, and improve taste and clarity. Consult your local distributor for information on Manitowoc’s full line of NSF-certified Tri-Liminator filtration systems. FILTER REPLACEMENT PROCEDURE Tri-Liminator systems include a pre-filter and a primary filter.
Maintenance Section 4 Removal from Service/Winterization GENERAL Special precautions must be taken if the ice machine is to be removed from service for an extended period of time or exposed to ambient temperatures of 32°F (0°C) or below. CAUTION If water is allowed to remain in the ice machine in freezing temperatures, severe damage to some components could result. Damage of this nature is not covered by the warranty. 4-10 SELF-CONTAINED AIR-COOLED ICE MACHINES 1.
Section 5 Before Calling for Service Section 5 Before Calling for Service Checklist If a problem arises during operation of your ice machine, follow the checklist below before calling for service. Routine adjustments and maintenance procedures are not covered by the warranty. Problem Possible Cause Ice machine does not operate. No electrical power to the ice machine. ON/OFF/ WASH toggle switch set improperly. Damper in open position (down).
Before Calling for Service Section 5 Problem Possible Cause Ice machine produces shallow Ice thickness probe is out of or incomplete cubes, or the ice adjustment. fill pattern on the evaporator is Water trough level is to high or too low. incomplete. Water float valve filter screen is dirty. Low ice capacity. To Correct Adjust the ice thickness probe. See page 3-5. Check the water level. See page 3-4. Remove and clean the filter screen. See page 4-8. Water filtration is poor. Replace the filter.
Section 5 SAFETY LIMITS General In addition to standard safety controls, the control board has two built in safety limit controls which protect the ice machine from major component failures. Safety Limit #1: If the freeze time reaches 60 minutes, the control board automatically initiates a harvest cycle. If three consecutive 60-minute freeze cycles occur, the ice machine stops. Safety Limit #2: If the harvest time reaches 3.
Before Calling for Service Section 5 Safety Limit #1 Freeze time exceeds 60 minutes for 3 consecutive freeze cycles. Possible Cause Improper installation Water system • • • • • • • • • • • • • • • • • • • • • • • • • Electrical system Restricted condenser air flow (air-cooled models) Refrigeration system Check/Correct See “Installation Instructions” Section 2 of this manual Low water pressure (20 psi minimum.)

Section 6 Service Section 6 Service WARNING An ice machine contains high voltage electricity and refrigerant charge. Repairs are to be performed by properly trained refrigeration technicians aware of the dangers of dealing with high voltage electricity and refrigerant under pressure. Main Fuse On/Off/ Wash Toggle Switch Function The control board fuse stops ice machine operation if electrical components fail causing high amp draw.
Service Section 6 Bin Switch Function Bin switch operation is controlled by the movement of the ice damper. The bin switch has two main functions: 1. Terminating the harvest cycle and returning the ice machine to the freeze cycle. This occurs when the bin switch is opened and closed again within 7 seconds of opening during the harvest cycle. 2. Automatic ice machine shut-off. If the storage bin is full at the end of a harvest cycle, the sheet of cubes fails to clear the ice damper and holds it down.
Service Section 6 Bin Switch Removal Q130 1. Disconnect power to the ice machine at service disconnect. Q210/Q270 1. Disconnect power to the ice machine at service disconnect. 2. Disconnect bin switch wires in control box. 2. Disconnect bin switch wires in control box. 3. Depress tab on right side of evaporator with thumb. 3. Insert a small screwdriver through the hole located in the top of the bin switch, and depress mounting tab slightly. 4. Slide bin switch to right to remove. 4.
Service Section 6 Fan Cycle Control Function Cycles the fan motor on and off to maintain proper operating discharge pressure. The fan cycle control closes on an increase, and opens on a decrease in discharge pressure.

Service Section 6 Condenser Fan Motor Replacement Access to remove, clean or replace the condenser fan/motor can be obtained by performing the following: 1. Disconnect electrical power to the ice machine at the electrical service disconnect. 2. Remove the screws that secure the condenser to the cabinet and the base to the cabinet. 3. Slide the base forward until contact is made with the stop screw (approximately 2.5" 6.3cm). CAUTION Do not move base past the stop screw, tubing damage could result. 4.
Service Section 6 Ice Thickness Probe (Harvest Initiation) MAXIMUM FREEZE TIME The control system includes a built-in safety, which will automatically cycle the ice machine into harvest after 60 minutes in the freeze cycle. ICE THICKNESS CHECK The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8” (3.2 mm).
Section 6 Service DIAGNOSING ICE THICKNESS CONTROL CIRCUITRY Ice Machine Does Not Cycle Into Harvest When Water Contacts The Ice Thickness Control Probe Step 1 Bypass the freeze time lock-in feature by moving the ON/OFF/WASH switch to OFF and back to ON. Wait until the water starts to flow over the evaporator. Step 2 Clip the jumper wire to the ice thickness probe and any cabinet ground.
