ICE DEFLECTOR

An ice deflector is required when the ice machine is installed on a bin. An ice deflector is not required when the ice machine is installed on a dispenser.

Manitowoc ice machines require a deflector when installed on an ice storage bin.

Prior to using a non-Manitowoc ice storage system with Manitowoc ice machines, contact the manufacturer to assure their ice deflector is compatible with Manitowoc ice machines.

Do not operate equipment that has been misused, abused, neglected, damaged, or altered/modified from that of original manufactured specifications.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision concerning use of the appliance by a person responsible for their safety.

Do not damage the refrigeration circuit when installing, maintaining or servicing the unit.

Do not use electrical appliances or accessories other than those supplied by Manitowoc for your ice machine model.

Part Number 000007345 2/12 5

General Information Section 1

BIN INSTALLATION

• All ice machines installed on a bin require an ice deflector.

• Manitowoc bins have a deflector installed and require no modifications when used with a forward facing evaporator.

• Ice machines with multiple evaporators require a deflector kit.

LUMINICE™

The LuminIce™ growth inhibitor recirculates the air in the ice machine foodzone over a UV bulb. This process will inhibit the growth of common micro-organisms on all exposed foodzone surfaces.

• LuminIce™ bulbs require replacement on a yearly basis.

• The control board can be set to automatically display a reminder after 12 months. Refer to LuminIce™ in section 3 for setup procedures.

Cleanup Procedure for Accidental Bulb Breakage

The cleanup procedure is identical to the procedure used to clean up compact fluorescent (CFL) or fluorescent tube lights. These lights contain a small amount of mercury sealed within a glass tube. Breaking these types of lights will release mercury and mercury vapor. The broken bulb can continue to release mercury vapor until it is cleaned up and removed.

The latest EPA procedures can be viewed on their website at www.epa.gov/cfl/cflcleanup.html.

DISPENSER INSTALLATION

• No adapter is needed for machines that match the size of the dispenser unless required by the dispenser manufacturer.

• 22" & 30" ice machines ship with the deflector/baffle required for dispenser usage. No additional deflector/ baffle is required, unless specified by the dispenser manufacturer.

• A bin thermostat to control ice level is recommended.

CONTROL PANEL BEZEL

The ice machine ships with two bezels:

• The standard bezel allows the display screen to be viewed and the menu, arrows and checkmark buttons can be accessed.

• The key guard bezel allows the display screen to be viewed and covers all buttons to prevent unauthorized settings from being entered. The ice machine door must be opened to access the control panel.

To change the bezel, open the ice machine door, remove the two screws securing the bezel and slide the bezel to the right while lifting forward.

An optional cover that completely hides the display is available as a sales kit, and is available through your local distributor or service company.

Air Conditioning

Heat of Rejection

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-contained aircooled ice machines are installed.

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

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

Removing Drain Plug and Leveling the Ice Storage Bin

To avoid instability the bin/dispenser must be installed in an area capable of supporting the weight of the bin/dispenser, ice machine and a full bin of ice. The bin/dispenser must be level side to side and front to back before installing the ice machine.

1. Remove threaded plug from drain fitting.

2. Screw the leveling legs onto the bottom of the bin.

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

The legs must be screwed in tightly to prevent them from bending.

4. Move the bin into its final position.

5. Level the bin to assure that the bin door closes and seals properly. Use a level on top of the bin. Turn the base of each foot as necessary to level the bin.

6. Inspect bin gasket prior to ice machine installation. (Manitowoc bins come with a closed cell foam gasket installed along the top surface of the bin.)

7. Remove all panels from ice machine before lifting. and installing on bin. Remove both front panels, top cover, left and right side panels.

Air Baffle

Self-Contained Air-cooled Only

The air-cooled baffle prevents condenser air from recirculating. To install:

1. Loosen the back panel screws next to the condenser.

2. Align the keyhole slots in the air baffle with the screw holes and slide the baffle down to lock in place.

Electrical Service

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).

The ice 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.

Observe correct polarity of incoming line voltage. Incorrect polarity can lead to erratic ice machine operation.

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.)

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.

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.

Connect to a potable water supply only.

WATER INLET LINES

Follow these guidelines to install water inlet lines:

• 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 restrictors installed for other equipment are working. (Check valves on sink faucets, dishwashers, etc.)

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

• Install a water shut-off valve for both the ice making and condenser water lines.

• Insulate water inlet lines to prevent condensation.

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

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.

WATER-COOLED CONDENSER WATER PRESSURE

Water pressure at the condenser cannot exceed 150 psig (1034 kPa) with the standard water-regulating valve. Contact your distributor if your water pressure is greater than 150 psig (1034 kPa). A special order condensing unit is available that allows water pressure up to 350 psig (2413 kPa)

COOLING TOWER APPLICATIONS (WATER-COOLED MODELS)

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°C).

• Water flow through the condenser must not exceed 5

gallons (19 liters) per minute.

• Allow for a pressure drop of 7 psi (50 kPa) between the condenser water inlet and the outlet of the ice machine.

• Water exiting the condenser must not exceed 110°F

(43°C).

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

• 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-cooled models.

Caution

GENERAL

Condensers must be mounted horizontally with the fan motor on top with nothing obstructing it. There must be at least a 16" (41 cm) clearance from the bottom for air intake. The front coupling panel and one other panel (back or side) must also be unobstructed.

Remote condenser installations consist of vertical and horizontal line sets between the ice machine and the condenser. When combined, they must fit within approved specifications. The following guidelines, drawings and calculation methods must be followed to verify a proper remote condenser installation.

The 60 month compressor warranty (including the 36 month labor replacement warranty) will not apply if the remote ice machine is not installed according to specifications.

This warranty also will not apply if the refrigeration system is modified with a condenser, heat reclaim device, or other parts or assemblies not manufactured by Manitowoc Ice unless specifically approved in writing by Manitowoc Ice.

GUIDELINES FOR ROUTING LINE SETS

First, cut a 2.5" (6.35 cm) circular hole in the wall or roof for tubing routing. The line set end with the 90° bend will connect to the ice machine. The straight end will connect to the remote condenser.

Follow these guidelines when routing the refrigerant lines. This will help ensure proper performance and service accessibility.

1. Optional - Make the service loop in the line sets (as shown below). This permits easy access to the ice machine for cleaning and service. Do not use hard rigid copper at this location.

2. Required - Do not form traps in the refrigeration lines (except the service loop). Refrigerant oil must be free to drain toward the ice machine or the condenser. Route excess tubing in a supported downward horizontal spiral (as shown below). Do not coil tubing vertically.

3. Required - Keep outdoor refrigerant line runs as short as possible.

CALCULATING REMOTE CONDENSER INSTALLATION DISTANCES

Line Set Length

The maximum length is 100' (30 m). The ice machine compressor must have the proper oil

return. The receiver is designed to hold a charge sufficient to operate the ice machine in ambient temperatures between -20°F (-29°C) and 120°F (49°C), with line set lengths of up to 100' (30 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m). The maximum drop is 15' (4.5 m).

If a line set has a rise followed by a drop, another rise cannot be made. Likewise, if a line set has a drop followed by a rise, another drop cannot be made.

Calculated Line Set Distance

The maximum calculated distance is 150' (45 m). Line set rises, drops, horizontal runs (or combinations of

these) in excess of the stated maximums will exceed compressor start-up and design limits. This will cause poor oil return to the compressor.

Make the following calculations to make sure the line set layout is within specifications.

1. Insert the measured rise into the formula below. Multiply by 1.7 to get the calculated rise.



(Example: A condenser located 10 feet above the ice machine has a calculated rise of 17 feet.)

2. Insert the measured drop into the formula below. Multiply by 6.6 to get the calculated drop.



(Example. A condenser located 10 feet below the ice machine has a calculated drop of 66 feet.)

3. Insert the measured horizontal distance into the formula below. No calculation is necessary.

4. Add together the calculated rise, calculated drop, and horizontal distance to get the total calculated distance. If this total exceeds 150' (45 m), move the condenser to a new location and perform the calculations again.

Maximum Line Set Distance Formula

Step 1. Measured Rise (35' [10.7 m] Maximum) ______ x 1.7 = _______ Calculated Rise Step 2. Measured Drop (15' [4.5 m] Maximum) ______ x 6.6 = _______ Calculated Drop Step 3.

LENGTHENING OR REDUCING LINE SET LENGTHS

In most cases, by routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser.

The quick connect fittings on the line sets are equipped with Schraeder valves. Use these valves to recover any vapor charge from the line set. When lengthening or shortening lines follow good refrigeration practices, purge with nitrogen and insulate all tubing. Do not change the tube sizes. Evacuate the lines and place about 5 oz (143g) of vapor refrigerant charge in each line.

CONNECTING A LINE SET

1. Remove the dust caps from the line set, condenser and ice machine.

2. Apply refrigeration oil to the threads on the quick disconnect couplers before connecting them to the condenser.

3. Carefully thread the female fitting to the condenser or ice machine by hand.

4. Tighten the couplings with a wrench until they bottom out.

REMOTE RECEIVER SERVICE VALVE

The receiver service valve is closed during shipment. Open the valve prior to starting the ice machine.

1. Remove the top and left side panels.

2. Remove the receiver service valve cap.

3. Backseat (open) the valve.

4. Reinstall the cap and panels.

5. Turn an additional 1/4 turn to ensure proper brassto-brass seating. Torque to the following specifications:

Caution

Remote Ice Machine Usage with Non-Manitowoc Multi-Circuit Condensers

WARRANTY

The sixty (60) month compressor warranty, including thirty six (36) month labor replacement warranty, shall not apply when the remote ice machine is not installed within the remote specifications. The foregoing warranty shall not apply to any ice machine installed and/or maintained inconsistent with the technical instructions provided by Manitowoc Ice. Performance may vary from Sales specifications. ARI certified standard ratings only apply when used with a Manitowoc remote condenser.

If the design of the condenser meets the specifications, Manitowoc’s to be extended to the Manitowoc manufactured part of the system. Since Manitowoc does condenser in conjunction with the ice machine, Manitowoc will not endorse, recommend, or approve the condenser, and will not be responsible for its performance or reliability.

Manitowoc warrants only complete new and unused remote packages. Guaranteeing the integrity of a new ice machine under the terms of our warranty prohibits the use of pre-existing (used) tubing or condensers.

HEAD PRESSURE CONTROL VALVE

Any remote condenser connected to a Manitowoc  Ice Machine must have a head pressure control valve (available from Manitowoc Distributors) installed on the condenser package. Manitowoc will not accept substitute “off the shelf” head pressure control valves.

only approval is for full warranty coverage

not test the

FAN MOTOR

The condenser fan must be on during the complete ice machine freeze cycle (do not cycle on fan cycle control). The ice maker has a condenser fan motor circuit for use with a Manitowoc condenser. It is recommended that this circuit be used to control the condenser fan(s) on the multi-circuit condenser to assure it is on at the proper time. Do not exceed the rated amps for the fan motor

circuit listed on the ice machine’s serial tag. INTERNAL CONDENSER VOLUME

The multi-circuit condenser internal volume must not be less than or exceed that used by Manitowoc (see chart on next page). Do not exceed internal volume and try

to add charge to compensate, as compressor failure will result.

CONDENSER T

T is the difference in temperature between the condensing refrigerant and entering air. The T should be 15 to 20°F (-9.4 to -6.6°C) at the beginning of the freeze cycle (peak load conditions) and drop down to 12

to 17°F (-11.1 to -8.3°C) during the last 75% of the

freeze cycle (average load conditions).

REFRIGERANT CHARGE

Remote ice machines have the serial plate refrigerant charge (total system charge) located in the ice maker section. (Remote condensers and line sets are supplied with only a vapor charge.)

Never add more than nameplate charge to ice machine for any application.

QUICK CONNECT FITTINGS

Do not use a fan cycling control to try to maintain discharge pressure. Compressor failure will result.

Part Number 000007345 2/12 17

The ice machine and line sets come with quick connect fittings. It is recommended that matching quick connects (available through Manitowoc Distributors) be installed in the multi-circuit condenser, and that a vapor “holding” charge, 5 oz. (150 ml), of proper refrigerant be added to the condenser prior to connection of the ice machine or line set to the condenser.
