Q130/Q210/Q270 ICE MACHINE

TOTAL CIRCUIT AMPACITY

The total circuit ampacity is used to help select the wire size of the electrical supply.

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.

GROUND FAULT CIRCUIT INTERUPTER

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, Inc. 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.

Installation Instructions

 

 

Water Service/Drains

WATER SUPPLY

Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, remove chlorine, and improve taste and clarity.

! Warning

PERSONAL INJURY POTENTIAL

For ice making, connect to a potable water supply only.

Important

If you are installing a Manitowoc 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

(80 psig-551.5kPA) recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.

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

Insulate water inlet lines to prevent condensation.

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 water-cooledcondenser drain lines. Insulate them to prevent condensation.

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

COOLING TOWER APPLICATIONS

(Water-CooledModels)

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).

Important

The Commonwealth of Massachusetts requires that all water-cooledmodels must be connected only to a closed loop, cooling tower system.

Operation

Ice Making Sequence of Operation

INITIAL START-UPORSTART-UPAFTER AUTOMATICSHUT-OFF

1. Pressure Equalization

Before the compressor starts the hot gas valve is energized for 15 seconds to equalize pressures during the initial refrigeration system start-up.

2. Refrigeration System Start-Up

The compressor starts after the 15-secondpressure equalization, and remains on throughout the entire Freeze and Harvest Sequences. The hot gas valve 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 relay. As a result, any time the relay coil is energized, the compressor and fan motor are supplied with power.)

FREEZE SEQUENCE 3. Prechill

The compressor is on for 30 seconds prior to water flow to Prechill the evaporator.

4. Freeze

The water pump starts after the 30-secondPrechill. An even flow of water is directed across the evaporator and into each cube cell, where it freezes.

When sufficient ice has formed, the water flow (not the ice) contacts the ice thickness probe. After approximately 7 seconds of continual water contact, the Harvest Sequence is initiated. The ice machine cannot initiate a Harvest Sequence until a 6-minutefreeze time has been surpassed.

HARVEST SEQUENCE 5. Harvest

The water pump de-energizesstopping flow over the evaporator. The rising level of water in the sump trough diverts water out of the overflow tube, purging excess minerals from the sump trough. The hot gas valve also opens to divert hot refrigerant gas into the evaporator.

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 contacts the ice damper, 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 (steps 3 - 4).

AUTOMATIC SHUT-OFF

6. Automatic Shut-Off

When the storage bin is full at the end of a Harvest Sequence, the sheet of cubes fails to clear the ice damper and will hold it down. After the ice damper is held open for 7 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 damper. As the ice damper swings back to the operating position, the bin switch re-closesand the ice machine restarts (steps 1 - 2), provided the3-minutedelay period is complete.

Operational Checks

GENERAL

Your Manitowoc ice machine was factory-operatedand adjusted before shipment. Normally, a newly installed ice machine does not require any adjustment.

To ensure proper operation, always follow these Operational Checks when starting the ice machine:

for the first time

after a prolonged out of service period

after cleaning and sanitizing

Routine adjustments and maintenance procedures outlined in this manual are not covered by the warranty.

SIPHON SYSTEM

To reduce mineral build-upand cleaning frequency, the water in the sump trough must be purged during each harvest cycle.

When the water pump de-energizesthe level in the water trough rises above the standpipe starting a siphon action. The siphon action stops when the water level in the sump trough drops. When the siphon action stops, the float valve refills the water trough to the correct level.

Siphon System Check

Follow steps 1 through 6 under water level check.
