Location of Ice Machine

The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location.

The location must be free of airborne and other contaminants.

The air temperature must be at least 35°F (1.6°C), but must not exceed 110°F (43.4°C).

The location must not be near heat-generatingequipment or in direct sunlight and must be protected from weather.

The location must not obstruct air flow through or around the ice machine. Refer to the chart below for clearance requirements.

*There is no minimum clearance required for water-cooledor remote ice machines. This value is recommended for efficient operation and servicing only.

! Caution

The ice machine must be protected if it will be subjected to temperatures below 32°F (0°C). Failure caused by exposure to freezing temperatures is not covered by the warranty. See “Removal from Service/Winterization”.

Ice Machine Heat of Rejection

Heat of Rejection

Ice Machine

Air Conditioning

Peak

S600M

B.T.U./Hour

Because the heat of rejection varies during the ice making cycle, the figure shown is an average.

Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the amount of heat rejected by the ice machine when sizing air conditioning equipment where self-containedaircooled ice machines are installed.

This information is also necessary when evaluating the benefits of using water-cooledor remote condensers to reduce air conditioning loads. The amount of heat added to an air conditioned environment by an ice machine using awater-cooledor remote condenser is negligible.

Knowing the amount of heat rejected is also important when sizing a cooling tower for a water-cooledcondenser. Use the peak figure for sizing the cooling tower.

Electrical Service

GENERAL

! Warning

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

VOLTAGE

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

Important

Observe correct polarity of incoming line voltage.

Fuse/Circuit Breaker

A separate fuse/circuit breaker must be provided for each ice machine. Circuit breakers must be H.A.C.R. rated (does not apply in Canada).

MINIMUM 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.)

! Warning

The ice machine must be grounded in accordance with national and local electrical codes.

S Series Ice Machines (* indicates preliminary data)

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.

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.

Important

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.

WATER INLET LINES

Follow these guidelines to install water inlet lines:

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

If water pressure exceeds the maximum recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.

Install a water shut-offvalve for both the ice making and condenser water lines.

Insulate water inlet lines to prevent condensation.

! Caution

Do not apply heat to water valve inlet fitting. This will damage plastic valve body.

DRAIN CONNECTIONS

Follow these guidelines when installing drain lines to prevent drain water from flowing back into the ice machine and storage bin:

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.

Run separate bin and ice machine drain lines. Insulate them to prevent condensation.

Vent the bin and ice machine drain to the atmosphere. Do not vent the condenser drain on water-cooledmodels.

Cooling Tower Applications

A water cooling tower installation does not require modification of the ice machine. The water regulator valve for the condenser continues to control the refrigeration discharge pressure.

It is necessary to know the amount of heat rejection, and the pressure drop through the condenser and water valves (inlet and outlet) when using a cooling tower on an ice machine.

Water entering the condenser must not exceed 90°F (32.2°C).

Water flow through the condenser must not exceed 5 gallons (19 liters) per minute.

Allow for a pressure drop of 7 psi (48 kPA) between the condenser water inlet and the outlet of the ice machine.

Water exiting the condenser must not exceed 110°F (43.3°C).

Ice Machine Operation

Section 3

 

 

Sequence Of Operation

NOTE: The toggle switch must be in the ice position and the water curtain must be in place on the evaporator before the ice machine will start.

INITIAL START-UPORSTART-UPAFTER AUTOMATICSHUT-OFF

1. Water Purge

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

The harvest valve(s) is also energized during water purge, although it stays on for an additional 5 seconds (50 seconds total on time) during the initial refrigeration system start-up.

When Used - The air compressor energizes for the last 10 seconds of the cycle.

2. Refrigeration System Start-Up

The compressor starts after the 45 second water purge, and it remains on throughout the entire Freeze and Harvest Sequences. The water fill valve is energized at the same time as the compressor. The harvest valve(s) remains on for 5 seconds during initial compressor startup and then shuts off.

At the same time the compressor starts, the condenser fan motor (air-cooledmodels) is supplied with power throughout the entire Freeze and Harvest Sequences. The fan motor is wired through a fan cycle pressure control, therefore it may cycle on and off. (The compressor and condenser fan motor are wired through the contactor. As a result, anytime the contactor coil is energized, the compressor and fan motor are supplied with power.)

FREEZE SEQUENCE 3. Prechill

The compressor is on for 30 seconds (60 seconds initial cycle) prior to water flow, to prechill the evaporator. The water fill valve remains on until the water level probe is satisfied.

4. Freeze

The water pump restarts after the prechill. An even flow of water is directed across the evaporator and into each cube cell, where it freezes. The water fill valve will cycle on and then off one more time to refill the water trough.

When sufficient ice has formed, the water flow (not the ice) contacts the ice thickness probe. After approximately 10 seconds of continual water contact, the harvest sequence is initiated. The ice machine cannot initiate a harvest sequence until a 6 minute freeze lock has been surpassed.

NOTE: Freeze lock is bypassed after moving the toggle switch from OFF to ICE position for the first cycle only.

Section 3

Ice Machine Operation

 

 

HARVEST SEQUENCE 5. Water Purge

The harvest valve(s) opens at the beginning of the water purge to divert hot refrigerant gas into the evaporator.

The water pump continues to run, and the water dump valve energizes for 45 seconds to purge the water in the sump trough. The water fill valve energizes (turns on) and de-energizes(turns off) strictly by time. The water fill valve energizes for the last 15 seconds of the45-secondwater purge.

After the 45 second water purge, the water fill valve, water pump and dump valve de-energize.(Refer to “Water Purge Adjustment” for details.)

6. Harvest

The harvest valve(s) remains open and the refrigerant gas warms the evaporator causing the cubes to slide, as a sheet, off the evaporator and into the storage bin. The sliding sheet of cubes swings the water curtain out, opening the bin switch.

The momentary opening and re-closingof the bin switch terminates the harvest sequence and returns the ice machine to the freeze sequence (Step 3 - 4.)

When Used - The air compressor energizes after 35 seconds and remains energized throughout the entire harvest cycle. The air compressor will automatically energize for 60 seconds when the harvest cycle time exceeded 75 seconds in the previous cycle.

AUTOMATIC SHUT-OFF

7. Automatic Shut-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 will hold it open. After the water curtain is held open for 30 seconds, the ice machine shuts off. The ice machine remains off for 3 minutes before it can automatically restart.

The ice machine remains off until enough ice has been removed from the storage bin to allow the ice to fall clear of the water curtain. As the water curtain swings back to the operating position, the bin switch re-closesand the ice machine restarts (steps 1 - 2), provided the 3 minute delay period is complete.

SAFETY TIMERS

The control board has the following non-adjustablesafety timers:

The ice machine is locked into the freeze cycle for 6 minutes before a harvest cycle can be initiated. Freeze lock is bypassed after moving the toggle switch from OFF to ICE position for the first cycle only.

The maximum freeze time is 60 minutes at which time the control board automatically initiates a harvest sequence (steps 5 & 6).

The maximum harvest time is 3.5 minutes at which time the control board automatically initiates a freeze sequence (steps 3 & 4).

WARM WATER RINSE CYCLE

Closing the back of the evaporator allows ice to build up on the rear of the evaporator and the plastic evaporator frame parts. After 200 freeze/harvest cycles have been complete the control board will initiate a warm water rinse.

After the 200th harvest cycle ends:

The Clean and Harvest LED’s energize to indicate the ice machine is in a warm water rinse.

The compressor and harvest valve remain energized.

The water pump energizes.

The water inlet valve energizes until water contacts the water level probe.

The compressor and harvest valve warm the water for 5 minutes, then de-energize.

The water pump remains energized for an additional 5 minutes (10 minute total on time) then deenergizes.

NOTE: The warm water rinse cycle can be terminated by moving the toggle switch to the OFF position, then back to ICE.

Operational Checks

GENERAL

Manitowoc ice machines are factory-operatedand 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.

WATER LEVEL

The water level sensor is set to maintain the proper water level above the water pump housing. The water level is not adjustable. If the water level is incorrect, check the water level probe for damage (probe bent, etc.). Clean the water level probe with ice machine cleaner, rinse thoroughly and re-checkoperation. Repair or replace the probe as necessary.

Water Level Probe Location

ICE THICKNESS CHECK

The ice thickness probe is factory-setto maintain the ice bridge thickness at 1/8" (.32 cm).

NOTE: Make sure the water curtain is in place when performing this check. It prevents water from splashing out of the water trough.

1.Inspect the bridge connecting the cubes. It should be about 1/8" (.32 cm) thick.

2.If adjustment is necessary, turn the ice thickness probe adjustment screw clockwise to increase bridge thickness, counterclockwise to decrease bridge thickness. Set at 1/4” gap between ice machine and evaporator as starting point, then adjust to achieve a 1/8” bridge thickness.
