Canceling a 24 hour delay period

• Press the power button while a delay period is active.
• Follow "Repeat Delay Period every 24 Hours" to step 5.
• Disconnect/reconnect the main power supply.

Sequence of Operation

Depending on ambient conditions and cold water supply temperature, the ice making process will take approximately 30 minutes.

Step 1 Initial Start-Up or Start-Up After Automatic Shut-Off — Water Fill

Before the compressor starts, the water inlet valve will energize to purge old water from the system for about 3 minutes.

Step 2 Refrigeration System Start-Up

The compressor starts after the Water Fill cycle and remains on throughout the Freeze and Harvest cycles. The condenser fan motor starts and runs throughout the Freeze cycle.

Step 3 Freeze

The water pump sprays water into the inverted cups. The water freezes layer by layer, until an ice cube forms in each cup. The control system will adjust the length of the Freeze cycle to conditions.

Step 4 Harvest

The water pump shuts off and the water inlet valve starts up to assist harvest and refill the water sump. The evaporator is warmed, allowing the cubes to release from the evaporator and drop into the storage bin. The control system will adjust length of time the ice machine remains in the harvest cycle and when the condenser fan motor is on or off during the harvest cycle. At the end of the harvest cycle the ice machine will start another freeze cycle (step 3).

Step 5 Automatic Shut-Off

The level of ice in the storage bin controls the ice machine shut-off. When the bin is full, ice will contact the bin thermostat bulb holder. The bin thermostat bulb cools, which stops the ice machine. The ice machine remains off until ice no longer contacts the bin thermostat bulb holder and the thermostat bulb warms up. The increase in temperature will restart the ice machine (step 1).

SAFETY TIMERS

The control board has the following non-adjustable safety timers:

• Initial cycle is 5 minutes longer than subsequent cycles.
• The ice machine is locked into the freeze cycle for 10 minutes (15 minutes initial cycle) before a harvest cycle can be initiated.
• The maximum freeze time is 120 minutes at which time the control board automatically initiates a harvest cycle (step 4).
• The maximum harvest time is 5 minutes at which time the control board automatically starts a freeze cycle.

Operational Checks

Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, new installations do not require any adjustment.

To ensure proper operation, always follow the Operational Checks:

• when starting the ice machine for the first time
• after a prolonged out of service period
• after de-scaling and sanitizing

NOTE: Routine adjustments and maintenance procedures are not covered by the warranty.

WATER LEVEL

The ice machine maintains the correct water level. The water level is not adjustable.

BIN THERMOSTAT ADJUSTMENT

The bin thermostat stops the ice machine when the bin is full. Turn the thermostat to the left to decrease the level of ice in bin or to the right to increase the level of ice in bin.

TESTING AND ADJUSTING THE BIN THERMOSTAT

The bin thermostat stops the ice machine when the bin is full. It is preset for normal ambient temperatures and adjustments are usually not required.

The thermostat is functioning correctly if, when three ice cubes are placed on the thermostat tube for 5 minutes, the ice machine stops. The ice machine should restart 5 minutes after the cubes are removed.

If the ice machine stops before the bin is full or runs after the bin is full, ambient temperatures are probably high or low and the bin thermostat can be adjusted as follows:

1. To access the thermostat, remove the two screws attaching the front grill and remove the grill.
2. Turn the thermostat to the left to decrease the level of ice before automatic shut-off. Turn to the right to increase the level of ice before automatic shut-off.
3. Reassemble the plastic panel and grill.

Cube Weight Adjustment

The cube weight can be increased from the factory setting by adjusting the finish time.

ADDITIONAL FINISHING TIME CHECK

Press and hold the power button for 5 seconds.

Count the flashes on the Automatic Ice Making light.

The light will flash once for each additional minute of freeze cycle time.

Adjust in 1 minute increments and allow the ice machine to run several freeze/harvest cycles, then inspect the ice cubes. If a heavier cube weight is desired add another minute of freeze time and repeat the process.

1. Press and hold the power button.
2. Press and release the clean button once for each additional minute of freeze cycle time desired.
3. Five minutes is the maximum additional freeze time that can be added. Pressing the clean button 6 times will reset the finishing time to zero additional minutes.

Cube weight increases or decreases depending on the amount of dimple in the cube

Section 4

Maintenance

Interior De-scaling and Sanitizing

GENERAL

De-scale and sanitize the ice machine every six months for efficient operation. If the ice machine requires more frequent de-scaling and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment.

The ice machine must be taken apart for de-scaling and sanitizing.

Sanitizing for Exterior, Remedial, and Detailed procedures can be performed independently and more frequently than de-scaling when needed.

A 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.

Caution

ICE MACHINE INSPECTION

Check all water fittings and lines for leaks. Also, make sure the refrigeration tubing is not rubbing or vibrating against other tubing, panels, etc.

Do not put anything (boxes, etc.) in front of the ice machine. There must be adequate airflow through and around the ice machine to maximize ice production and ensure long component life.

EXTERIOR CLEANING

Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation.

Sponge any dust and dirt off the outside of the ice machine with mild soap and water. Wipe dry with a clean, soft cloth.

Clean up any fallen ice or water spills as they occur.

CLEAN THE CONDenser

A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life.

• Clean the condenser at least every six months.
• Shine a flashlight through the condenser to check for dirt between the fins.
• Compressed air can be blown through the condenser fins. This procedure will raise considerable dust and is best performed outside. Be careful not to bend the fan blades.
• If dirt or grease remains between the fins or the condenser fins are bent or flattened, consult your service representative.

Removal from Service/Long Term Storage/Winterization

1. Perform a de-scaling and sanitizing procedure to prevent mildew growth.
2. Disconnect the electric power at the circuit breaker or the electric service switch.
3. Turn off the water supply.
4. Remove the water from the water trough.
5. Disconnect and drain the incoming ice-making water line at the rear of the ice machine.
6. Disconnect vinyl hose from water pump and allow to drain.
7. Make sure water is not trapped in any of the water or drain lines. Compressed air can be used to blow out the lines.
8. Use a spray bottle and a solution of sanitizer/water (0.50 oz/1 gal) and spray all interior surfaces. Do not rinse, allow to air dry.
9. Block the door partially open to provide air exchange and prevent mildew growth.
