Operation

Operational Checks

GENERAL

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 cleaning and sanitizing

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

Important

Refrigeration compressors must be operated for a minimum break in period of 24 hours before full ice production will be reached.

Part Number: 000015431 Rev01 5/19 57

ICE THICKNESS CHECK

The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8 in. (3 mm).

NOTE: Make sure the water curtain/splash shields are in place when performing this check. It prevents water from splashing out of the water trough. Remove the curtain to make an adjustment, then replace immediately after the adjustment is made.

1. Inspect the bridge connecting the cubes. It should be about 1/8 in. (3 mm) thick.

2. If adjustment is necessary, turn the ice thickness probe adjustment screw clockwise to increase bridge thickness or counterclockwise to decrease bridge thickness. Set a 9/32" gap between the ice thickness probe and evaporator as a starting point. Then adjust to achieve 1/8" ice thickness.

3. Make sure the ice thickness probe wire and the bracket do not restrict movement of the probe.

58 Part Number: 000015431 Rev01 5/19

Control Board Timers

The control board has the following non-adjustable timers:

• The ice machine is locked into the freeze cycle for 6

minutes before a harvest cycle can be initiated. This can be overridden by initiating a manual harvest. Refer to “Manual Harvest” on page 75.

• The maximum freeze time is 35 minutes at which time

the control board automatically initiates a harvest sequence.

• The maximum harvest time is 7 minutes, the control

board will perform a remove thaw cycle and then return the ice machine to the freeze cycle.

• Maximum water fill time in the freeze cycle:

• Single evaporator 6 minutes.

• Dual evaporator 8 minutes.

Part Number: 000015431 Rev01 5/19 59

Sequence of Operation

QUIETQUBE® MODELS

NOTE: The power button must be depressed and the water curtain/ice dampers must be in place on the evaporator before the ice machine will start.

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

1. Water Purge

Before the compressor starts, the water pump and water dump solenoid are energized to purge the ice machine of old water. This feature ensures that the ice making cycle starts with fresh water.

2. Refrigeration System Start-Up

Ice Machine Head Section:

The harvest valve(s), air pump(s) and liquid line solenoid valve energize to equalize high and low side refrigeration pressure. After 10 seconds the harvest valve(s) and air pump(s) de-energize.

CVD Condensing Unit:

The low pressure switch closes and sends voltage to the time delay relay. The time delay relay when closed sends voltage to the contactor coil, which energizes the compressor.

60 Part Number: 000015431 Rev01 5/19

FREEZE SEQUENCE

3. Prechill

The compressor lowers the temperature of the evaporator(s) before the water pump is energized. The water fill valve will energize and remain on until water completes the water level probe circuit.

4. Freeze

The water pump energizes and water flows over the evaporator. After water contacts the water level probe the water fill valve de-energizes. The control board will automatically cycle the water fill valve. The valve energizes once in the pre-chill and up to twice in the freeze cycle.

The freeze cycle continues until the six minute freeze lock expires and enough ice has formed to send a signal from the ice thickness probe to the control board.

Water Pump

The water pump(s) energizes and water flows over the evaporator. The water pump is energized throughout the freeze cycle.

Part Number: 000015431 Rev01 5/19 61

Water Inlet Valve

The water inlet valve energized in prechill. After water contacts the low and high water probes the water fill valve de-energizes. Ice builds on the evaporator and the water level drops. When water loses contact with the high water probe, the water fill valve energizes until water contacts the high water probe again.

Maximum Fill Time = Prechill fill time + first fill + second fill.

SINGLE EVAPORATOR MAXIMUM FILL TIME

Initial startup or startup after automatic shutoff

Prechill (2 minutes) + first fill time (6 minutes) + second fill time (6 minutes) = 14.0 minutes.

Consecutive cycles

Prechill (30 sec.) + first fill time (6 minutes) + second fill time (6 minutes) = 12.5 minutes.

DUAL EVAPORATOR MAXIMUM FILL TIMES

Initial startup or startup after automatic shutoff

Prechill (2 minutes) + first fill time (8 minutes) + second fill time (8 minutes) = 18.0 minutes.

Consecutive cycles

Prechill (30 sec.) + first fill time (8 minutes) + second fill time (8 minutes) = 16.5 minutes.

62 Part Number: 000015431 Rev01 5/19

HARVEST SEQUENCE

5. Water Purge

The air pump(s) and the harvest valve(s) open at the beginning of the water purge to divert refrigerant gas into the evaporator.

The water pump continues to run, and the water dump valve energizes to purge the water in the water trough.

CVD Condensing Unit:

When the refrigerant pressure is low enough to open the fan cycling pressure control the condenser fan motor stops.

6. Harvest

The air pump(s) remain energized and the harvest valve(s) remains open. The refrigerant gas warms the evaporator causing the cubes to begin melting and slide, as a sheet, off the evaporator and into the storage bin. If the damper/curtain does not open within 3.5 minutes in the harvest cycle the following occurs:

• 3.5 minutes - The water inlet valve energizes until

water touches the high water level probe.

• 4 minutes - The water pump energizes.

• 6.5 to 7 minutes - The water dump valve energizes.

• If bin switch does not open before 7 minutes the ice

machine will start a Thaw Cycle xx

Single evaporator models - The sliding sheet of cubes opens the water curtain/ice damper and bin switch.

The momentary opening and re-closing of the bin switch will terminate the harvest sequence and return to the freeze sequence (Step 3 - 4).

Dual evaporator models - The sliding sheet of cubes opens the ice damper and bin switch. The momentary opening and re-closing of the bin switch de-energizes the harvest valve for that evaporator. When the bin switches have opened and closed for both evaporators the ice machine will terminate the harvest sequence and return to the freeze sequence (Step 3 - 4).

Part Number: 000015431 Rev01 5/19 63

AUTOMATIC SHUT-OFF

7. Automatic Shut-Off

Ice Machine Section: Shuts off when:

• The storage bin is full at the end of a harvest sequence.

• The sheet of cubes fails to clear the water curtain and holds it open.

• One or both ice dampers are held down.

• Bin level probe thermistor senses setpoint (when used).

After the water curtain or ice damper are held open for 30 seconds, the ice machine shuts off. The ice machine control board starts a 10 minute delay which must time out before the ice machine can automatically restart.

CVD Condensing Unit: The liquid line solenoid valve closes and the condensing unit pumps down. The LPCO opens, starts a five minute delay period and de-energizes the contactor coil, which de-energizes the compressor and condenser fan motor.

RESTART AFTER AUTOMATIC SHUT-OFF

The ice machine remains off until enough ice has been removed to allow the ice to fall clear of the water curtain or ice damper. As the water curtain or ice damper swings back to the operating position, the bin switch re-closes and the ice machine restarts (steps 1 - 2), provided the 10 minute control board delay period and 5 minute condensing unit delay periods have completed.

THAW CYCLE

When the damper/curtain does not open during the 7 minute harvest cycle the following ice thaw cycle occurs:

• The compressor, harvest solenoid valve and dump valve de-energize. The water pump remains energized and the water inlet valve energizes until water touches the high water level probe.

• Water is circulated, dumped and refilled to the high water level probe for 3 minutes. Model 1200 or smaller: Circulate 165 seconds, dump 45 seconds Model 1400 and larger: Circulate 240 seconds, dump 120 seconds

• At the end of the thaw cycle the ice machine will start another freeze cycle (approximately 1 - 1.75 hour).

Curtain Operation In Water Assist Harvest

• Open & close damper = Continue Thaw Cycle

• Open damper 30 seconds = Full Bin Shutoff

Use the keypad and turn the ice machine off and then on to terminate the cycle. Disconnecting and reconnecting power to end the cycle will result in the ice machine restarting in a harvest cycle.

88 Part Number: 000015431 Rev01 5/19

SAFE OPERATION MODE

Allows the ice machine to operate up to 72 hours if the ice thickness probe (E19 fault) and/or water level probe sensors fail (E20 fault).

• When the control board starts the safe mode an alert is flashed on the LCD display to notify the end-user they have a production problem.

• The control board automatically initiates and monitors the safe mode. The control will automatically exit the safe mode if a normal signal is received from the input.

• After 72 hours the control board will enter a standby mode and turn off.

• The control board needs a five cycle history to operate safe mode. If five cycles have never been successfully completed the ice machine will shut-off.

Part Number: 000015431 Rev01 5/19 89

E01 LONG FREEZE CYCLE

If the freeze time reaches 35 minutes, the control board automatically initiates a harvest cycle. If 3 consecutive 35-minute freeze cycles occur, the ice machine stops.

E02 LONG HARVEST CYCLE

If the harvest time reaches 7 minutes, the control board will start a thaw cycle and automatically return the ice machine to the freeze cycle. After 3 consecutive long harvest cycles the ice machine stops.

ANALYZING WHY A SERVICE FAULT (E01 & E02)

STOPPED THE ICE MACHINE

Some service Faults are designed to stop the ice machine prior to major component failures, most often a minor problem or something external to the ice machine. This may be difficult to diagnose, as many external problems occur intermittently.

Example: An ice machine stops intermittently on E01 Long Freeze (long freeze time). The problem could be a low ambient temperature at night, a water pressure drop, the water is turned off one night a week, etc.

Refrigeration and electrical component failures will cause a Service Fault. Eliminate all electrical components and external causes first. If it appears that the refrigeration system is causing the problem, use Manitowoc’s procedures, charts, checklists, and other references to determine the cause.

The following checklists are designed to assist the service technician in analysis. However, because there are many possible external problems, do not limit your diagnosis to only the items listed.

SYMPTOM #2 LOW PRODUCTION, LONG FREEZE CYCLE

Ice Machine has a Long Freeze Cycle

Ice Formation is Thick or Thin ice fill at Inlet or Outlet of Evaporator or Low Production

Information must be verified to eliminate non-refrigeration problems which can cause good refrigeration components to appear defective.

Before starting, see “Before Beginning Service” on page 99 for a few questions to ask when talking to the ice machine owner.

Before Beginning Service

Ice machines may experience operational problems only during certain times of the day or night. A machine may function properly while it is being serviced, but malfunctions later. Information provided by the user can help the technician start in the right direction, and may be a determining factor in the final diagnosis.

Ask these questions before beginning service:

• When does the ice machine malfunction? (night, day,

all the time, only during the Freeze cycle, etc.)

• When do you notice low ice production? (one day a

week, every day, on weekends, etc.)

• Can you describe exactly what the ice machine seems

to be doing?

• Has anyone been working on the ice machine?

• During “store shutdown,” is the circuit breaker, water

supply or air temperature altered?

• Is there any reason why incoming water pressure

Ice Production Check

The amount of ice a machine produces directly relates to the operating water and air temperatures. This means a condensing unit with a 70°F (21°C) outdoor ambient temperature and 50°F (10°C) water produces more ice than the same model condensing unit with a 90°F (32°C) outdoor ambient temperature and 70°F (21°C) water.

1. Determine the ice machine operating conditions:

Air temp entering condenser: ____°

Air temp around ice machine: ____°

Water temp entering sump trough: ____°

2. Refer to the appropriate 24-Hour Ice Production Chart (starting on page 179). Use the operating conditions determined in step 1 to find published 24-Hour Ice Production:_____

• Times are in minutes.

Example: 1 min. 15 sec. converts to 1.25 min. (15 seconds ÷ 60 seconds = .25 minutes)

• Weights are in pounds.

Example: 2 lb. 6 oz. converts to 2.375 lb. (6 oz. ÷ 16 oz. = .375 lb.)
