2. Screw the foot of each leg in as far as possible.

3. Move the ice machine into its final position.

4. Use a level on top of the ice machine. Turn the base of

each foot as necessary to level the ice machine.

Warning All wiring must conform to local, state and national codes.

Caution The maximum allowable voltage variation is ±10% of the rated voltage at ice machine start-up (when the electrical load is highest).

Warning The machine must be grounded in accordance with national and local electrical codes. All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes. The following precautions must be observed:

• The ice machine must be grounded.

• A separate fuse/circuit breaker must be provided for each ice machine.

• A qualified electrician must determine proper wire size dependent upon location, materials used and length of run (minimum circuit ampacity can be used to help select the wire size).

• The maximum allowable voltage variation is ±10% of the rated voltage at ice machine start-up (when the electrical load is highest).

• Check all green ground screws in the control box and verify they are tight before starting the ice machine.

Caution Observe correct polarity of incoming line voltage. Incorrect polarity can lead to erratic ice machine operation. Operate equipment only on the type of electricity indicated on the specification plate.

TOTAL CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the wire size of the electrical supply. (Minimum circuit ampacity is not the ice machine’s running amp load.) The wire size (or gauge) is also dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician. ELECTRICAL REQUIREMENTS Refer to Ice Machine Model/Serial Plate for voltage/ amperage specifications.

GROUND FAULT CIRCUIT INTERRUPTER

Ground Fault Circuit Interrupter (GFCI/GFI) protection is a system that shuts down the electric circuit (opens it) when it senses an unexpected loss of power, presumably to ground. Manitowoc Ice does not recommend the use of a GFCI/GFI circuit protection with our equipment. If code requires the use of a GFCI/GFI then you must follow the local code. The circuit must be dedicated, sized properly and there must be a panel GFCI/GFI breaker. We do not recommend GFCI/GFI outlets as they are known for more intermittent nuisance trips than panel breakers. POWER SPECIFICATIONS Maximum breaker size is 15 amps. The wire size to the receptacle is dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician. Local, state or national requirements must be followed.Part Number 000016382 Rev 04 03/25 13

Section 2 Installation

Water Supply and Drain Requirements WATER SUPPLY Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and remove chlorine odor and taste. Water inlet fitting - 3/8" FPT

Warning Connect to a potable water supply only.

Follow these guidelines to install water inlet lines:

• The water temperature must be at least 50°F (10°C), but must not exceed 90°F (32°C).

• If you are installing a Manitowoc Arctic Pure® water filter system, refer to the Installation Instructions supplied with the filter system for ice making water inlet connections.

• Do not connect the ice machine to a hot water supply. Be sure all hot water check valves installed for other equipment are working. (Check valves on sink faucets, dishwashers, sprayer nozzles, etc.)

• If water pressure exceeds the maximum recommended pressure of 80 psi (552 kPa), obtain a water pressure regulator from your Manitowoc distributor.

• Insulate water inlet lines to prevent condensation.

Caution Do not apply heat to water valve inlet fitting. This will damage plastic water inlet connection. DRAIN CONNECTIONS Follow these guidelines when installing the supplied drain line to prevent drain water from flowing back into the ice machine storage bin: Drain fitting - 1/2" MPT

• Drain lines must have a 1.5 inch drop per 5 feet of run (2.5 cm per meter), and must not create traps.

• The floor drain must be large enough to accommodate drainage from all drains.14 Part Number 000016382 Rev 04 03/25 Installation Section 2 Installation Check List

• Have all of the electrical and water connections been made?

• Has the supply voltage been tested and checked against the rating on the nameplate?

• Is there proper clearance around the ice machine for air circulation?

• Is the ice machine grounded and polarity correct?

• Has the ice machine been installed where ambient temperatures will remain in the range of 50° - 100°F (10° - 38°C)?

• Are all refrigerant lines free from contact with other components?

• Are all electrical leads free from contact with refrigeration lines and moving equipment?

• Has the owner/operator been instructed regarding maintenance and proper descaling/sanitizing procedures?

• Has the owner/operator registered for warranty coverage on the Manitowoc Ice Website?

• Have the ice machine and bin been sanitized?

• Has the ice machine been turned on at the power switch and the power switch LED is energized?

• Has the cube weight been verified/adjusted to 21 to 24 grams (.75 - .85 oz)?Part Number 000016382 Rev 04 03/25 15 Sequence of Operation This ice machine is controlled by an electronic control module, while there are some mechanical switches, most functions and timers are controlled by the electronic control module. Refer to the “Troubleshooting Chart” on page 25 to diagnose the electronic control module. The electronic control module retains the power switch position in memory whenever power is disconnected and reconnected at the wall socket. Power Switch Position When Power Was Disconnected When Power Is Reconnected The Green LED On Flashes Off Remains Off Pre-Freeze The following occurs whenever power is applied to the ice machine by turning the power button on, or disconnecting/ reconnecting power: A. Pressing the power button energizes the water inlet valve to fill the water sump and the green LED will flash on/off for four minutes. The harvest valve is energized any time the unit is plugged in and the water pump is not running. The condenser fan motor has the potential to run any time the ice machine is plugged in. B. After 4 minutes the compressor starts, the water inlet valve remains energized and the LED stops flashing and remains solid green. C. At the end of the cycle the water inlet and harvest valves de-energize. FREEZE CYCLE The water pump energizes and the compressor remains energized, starting the freezing cycle. The pump sprays water into the inverted cups. The water freezes layer by layer, until an ice cube forms in each cup. At the same time the compressor starts, the condenser fan motor is supplied with power throughout the freeze and harvest cycles. The freeze cycle continues until the evaporator thermostat reaches the adjusted set point and an internal timer is satisfied. HARVEST CYCLE The compressor continues to operate and the water pump is de-energized. The harvest valve energizes, allowing hot gas from the compressor to enter and warm the evaporator. The water valve is also energized to aiding with harvest and refill the water sump with fresh water for a new freeze cycle. The ice falls from the cups and is directed into the bin by the ice cube slide. The harvest cycle continues until the evaporator thermostat set point is reached and an internal timer is satisfied. The harvest valve and water valve de-energize. If ice cubes are not contacting the bin thermostat, a new freeze cycle is initiated as the water pump energizes and sprays water into the cups. AUTOMATIC SHUTͳOFF When the storage bin is full, the ice will come in contact with the bin thermostat which is located inside the bin. The ice machine stops when the bin thermostat opens and the LED remains solid green. The ice machine remains off until enough ice has been removed from the storage bin to allow the bin thermostat to warm and close, starting a harvest cycle, then a freeze cycle. Important The coil on the harvest valve is energized whenever the ice machine is shut off on full bin. At times it is possible to hear a hum or slight buzz from the coil which is normal operation.

Ice Cube Thickness Check The ice cube thickness is factory-set to maintain the ice cube thickness at the proper size and weight.NOTE: A dimple in the end of each cube is normal. Adjusting to remove the dimple will result in longer freeze cycles and lower production.1. Allow the ice machine to operate for three complete cycles. The cubes should have a small dimple in the center.2. Cycle times vary, according to surrounding air and water inlet temperatures.3. If cubes are not full (large dimple), turn evaporator thermostat one increment towards the right to increase cube size. Allow ice machine to complete three cycles. Check cube.4. If cubes are too full, (no dimple), turn evaporator thermostat one increment towards the left to decrease cube size. Allow ice machine to operate three complete cycles. Ice Cube Weight Adjustment “The factory setting for the evaporator thermostat is 3.The cube weight can be increased or decreased from the factory setting by adjusting the evaporator thermostat. Turn the thermostat to the left to decrease the cube weight or to the right to increase the cube weight.NOTE: To access the bin thermostat or adjust cube weight, remove the front ice machine panel. Important Individual cube weight must be between 21 to 24 grams (.75 - .85 oz) to maximize production and energy efficiency.Part Number 000016382 Rev 04 03/25 17

Removal from Service/Long Term Storage/ 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.

Troubleshooting26 Part Number 000016382 Rev 04 03/25 Troubleshooting Section 5 Service Faults In addition to the standard safety controls, such as the high pressure cutout, your Manitowoc ice machine features built- in service faults which will stop the ice machine if conditions arise which could cause a major component failure. Before calling for service, re-start the ice machine using the following procedure:

1. Press the power button, the Green LED will go out.

2. Press the power button, the Green LED will illuminate

and the ice machine will perform a start-up sequence (refilling of water sump, harvest cycle, then freeze cycle).

3. Allow the ice machine to run to determine if the

condition repeats. If any of the below conditions repeat, call for service. A. The ice machine remains in the freeze cycle for more than 90 minutes (Ice Maker flashing the yellow light, one flash every 4 seconds). B. The ice machine remains in the harvest cycle for more than 30 minutes (Ice Maker flashing the yellow light, two flashes every 4 seconds). C. The ice machine shows a Green solid LED but the bin is empty. NOTE: Removal of the lower front panel is required to view the yellow LED. WAS H
