ABOUT YOUR ICE MACHINE

SECTION 2 ABOUT YOUR ICE MACHINE

COMPONENT LOCATION AND IDENTIFICATION

Figure 2. COMPONENT LOCATION/IDENTIFICATION

SEQUENCE OF OPERATION

INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF

1. Before the ice machine starts, the water pump and water dump solenoid are energized for 45 seconds to completely purge the sump trough of old water. This feature ensures that the ice-making cycle starts with fresh water.

2. The compressor and fan motor (air-cooled models) start after the water pump and water dump valve de-energize.
   FREEZE SEQUENCE

3. The water pump restarts after a 30-second delay. When the water pump is running, an even flow of water is directed across the evaporator and into each cube cell, where it freezes.

4. When sufficient ice has formed, the water flow contacts the ice thickness probe. After approximately seven seconds, the harvest sequence is initiated.
   HARVEST SEQUENCE

   • a. Both hot gas valves open, diverting hot refrigerant gas into the evaporators.
     b. The water dump solenoid is energized for 45 seconds to purge the water in the sump trough. After the 45-second purge, the water pump and water dump valve de-energize.

5. The hot refrigerant gas warms the evaporator, causing the cubes to slide, as a unit, off the evaporator, and into the storage bin. The sliding sheet of cubes swings the water curtain out, activating the bin switch. The momentary opening of the bin switch terminates the harvest sequence and returns the ice machine to the freeze sequence (Steps 3-4).

6. The sliding sheet of cubes swings the water curtain out, activating the bin switch. The momentary opening of the bin switch terminates the harvest sequence and returns the ice machine to the freeze sequence (Steps 3-4).
   AUTOMATIC SHUT-OFF

7. When the storage bin is full, the sheet of cubes fails to clear the water curtain and hold it open. If the water curtain is held open for more than seven seconds, the ice machine will shut off.

8. The ice machine remains off until enough ice has been removed from the storage bin so that the ice can drop clear of the water curtain. As the water curtain swings back to the operating position, the ice machine restarts. (Step 1-2).

OPERATIONAL CHECKS

• Your Manitowoc ice machine is factory-operated and adjusted before shipment.
• Normally, new installations do not require any adjustment.
• To ensure proper op- cration, always follow the Operational Checks when starting the ice machine for the first time, after a pro- longed “out of service” period, and after cleaning and sanitizing.
• Routine adjustments and maintenance procedures out- lined in this guide are not covered by the warranty.

WATER LEVEL CHECK (Figure 6)

1. Check the water level while the machine is in freeze mode and the water pump is running.
   Figure 6. WATER LEVEL CHECK

2. The water level is correct when it is 1/8″ – 1/2″ above the water pump impeller housing. The float valve is factory-set for the proper water level. Make the following adjustments if necessary:

   • a. Loosen the two screws on the float valve bracket.
   • b. Raise or lower the float valve assembly as needed, then re-tighten the screws,
   • c. If further adjustment is necessary, carefully bend the float arm to achieve the correct water level,

ICE THICKNESS CHECK (Figure 7)
The ice thickness probe is factory set to maintain the ice bridge thickness at 1/8″ Make sure the water curtain is in place when performing the Ice Thickness Check, The water curtain prevents water from splashing out of the water trough. Inspect the bridge connecting the cubes. The bridge should be approximately 1/8″ thick. Follow the steps below if any adjustment is needed.

1. Turn the ice thickness probe adjustment screw clockwise to increase the bridge thickness, or counterclockwise to decrease the bridge thickness.
   • Note: A 1/3 turn of the adjustment screw changes the ice thickness approximately 1/16*.
   • Figure 7. ICE THICKNESS CHECK
2. Make sure the ice-thickness probe wires and bracket do not restrict the movement of the probe.

MAINTENANCE

SECTION 3 MAINTENANCE

• Follow a general maintenance schedule to ensure reliable, trouble-free operation and maximum ice production.
• You are responsible for maintaining the ice machine by the instructions in this manual.
• Call your local qualified Manitowoc Service Representative to perform the maintenance if at any time you are either unsure or unaware of the proper procedures and safety precautions that must be followed.
• We recommend that you follow the maintenance guidelines on a semi-annual basis.
• Record the date you perform the maintenance procedures in the space provided.
• You can refer to the dates later to remind you to perform the maintenance procedures again.

MAINTENANCE GUIDELINES CHART

GENERAL 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 stack anything (boxes, etc.) on or around the ice machine.
• Do not cover the ice machine while it is operating.
• There must be adequate airflow through and around the ice machine to ensure long component life and maximize ice production.

EXTERIOR CLEANING

1. Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation.
2. Sponge any dust and dirt off the outside of the ice machine with mild soap and water. Wipe dry with a soft clean cloth.
   • Caution: Stainless steel panels should be cleaned with a mild soap or a commercial stainless steel cleaner. Do not use cleansers containing bleaching agents. They usually contain chlorine, which stains stainless steel. Heavy stains should be removed with stainless steel wool. Never use plain steel wool or abrasive pads. They will scratch the panels and cause rusting.

CLEANING THE CONDENSER A WARNING

• Disconnect the electric power to the ice machine and the remote condenser at the electric service switch box before cleaning the condenser.

AIR-COOLED 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.
• Caution
  • The condenser fins are sharp. Use care when cleaning them.
• Note
  • Remove the front cover and pull the bottom of the filter out first for removal.

1. The washable aluminum filter is designed to catch dust, dirt, lint, and grease. This helps keep the condenser clean. Clean the filter with a mild soap and water solution.
   • Figure 8. SELF-CONTAINED AIR-COOLED FILTER
2. Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Brush or wash the condenser from top to bottom – not from side to side. Be careful not to bend the fins. Shine a flashlight through the condenser to check for dirt between the fins.
   • If further cleaning is required, use one or both of the following procedures:
   • a. Blow compressed air through the condenser from the inside. Take care not to bend the fan blades. Shine a flashlight through the condenser to check that all the dirt is removed.
   • b. Clean with a commercial condenser coil cleaner, according to the directions and cautions supplied with the cleaner.
3. Straighten any bent condenser fins with a fin comb, Figure 9.
   • Figure 9. STRAIGHTEN BENT CONDENSER FINS
4. Carefully wipe off the fan blades and motor with a soft cloth, taking care not to bend the fan blades. Wash excessively dirty fan blades with warm soapy water, then rinse thoroughly.
   • Caution: If you are cleaning the condenser fan blades with water, cover the fan motor to prevent water damage

WATER-COOLED CONDENSER (AND WATER REGULATING VALVE)

• The water-cooled condenser and the water regulating valve may require cleaning due to scale build-up.
• Low ice production, high water consumption and high operating temperatures and pressures all may be symptoms of restrictions in the condenser water circuit.
• The cleaning procedures require special pumps and cleaning solutions.
• Therefore, they must be performed by qualified maintenance or service personnel.

INTERIOR CLEANING/SANITIZING- SELF-CLEANING SYSTEM (SeCS™)

• Clean and sanitize the ice machine every six months for efficient operation.
• If the ice machine requires more frequent cleaning and sanitizing consult a qualified service company to test the water quality and recommend appropriate water treatment or installation of AuCS™ accessory (Automatic Cleaning System).

BEFORE CALLING FOR SERVICE

SECTION 4 BEFORE CALLING FOR SERVICE
If a problem arises during the operation of your ice machine, follow the checklist below before calling for service.

CHECKLIST

SAFETY LIMIT FEATURE

In addition to standard safety controls, such as the high-pressure cutout, your Manitowoc ice machine features built-in safety limits which stop the ice machine if conditions exist that may result in a major component failure.
Before calling for service, restart the ice machine using the following procedures:

• a. Move the ICE/OFF/CLEAN switch to OFF and then back to ICE. If the safety limit feature has stopped the ice machine, it will restart after a short delay. Proceed to step 2.
• b. If the ice machine does not restart, refer to “Ice Machine Does Not Operate” in the problem checklist.
• Let the ice machine operate to determine if the condition recurs.
  • a. If the ice machine stops again, the condition recurs. Call for service.
  • b. If the ice machine continues to run, the condition corrects itself. Let the machine run.
