Bin Installation Requirements

• The installation area must be capable of supporting the combined weight of the equipment and product.

• 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.

• Align sides and back of ice machine with sides and back of bin when placing ice machine on bin.

• Optional sales kits are available to adapt various sized or multiple ice machines on large bins.

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.

16 Part Number: 000014141 Rev 05 11/18

NOTE: When using casters, the units must be tethered or secured to comply with all applicable codes. Swivel casters must be mounted on the front and rigid casters must be mounted on the rear. Lock the front casters after installation is complete.

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.

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.

Dispenser Installation

Observe following recommendations unless required by the dispenser manufacturer.

• An adapter is not required for ice machines that match the dispenser size.

• A deflector is not required.

• Ice level management is recommended to prevent water leakage or movement of ice machine during agitation.

• Align sides and back of ice machine with sides and back of dispenser when placing ice machine.

Part Number: 000014141 Rev 05 11/18 17

Installation Section 2

Electrical Requirements

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 (dedicated circuit) must be provided for each ice machine head section, condenser or condensing unit.

• 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).

Warning

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

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) also depends on location, materials used, length of run, etc., so it must be determined by a qualified electrician.

Ground Fault Circuit Interrupter

We do not recommend the use of a GFCI/ GFI circuit protection with our equipment. If a GFCI/GFI is required by code, use a GFCI/GFI breaker rather than an outlet, which is more prone to intermittent nuisance trips than panel circuit breakers.

Voltage

The maximum allowable voltage variation is +10% / -5% of the rated voltage at ice machine start-up (when the electrical load is highest).

Warning

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

Fuse/Circuit Breaker

A separate electrical disconnect, which disconnects all poles and has 3 mm (1/8") contact separation, must be provided for fixed wiring. Circuit breakers must be H.A.C.R. rated in USA.

The connection to the drinking water network must be made with a certified backflow preventer type EA (EN13959) and with a certified connection hose (EN13618 or EN61770) on site.

Part Number: 000014141 Rev 05 11/18 23

Installation Section 2

Cooling Tower Applications (Water-Cooled Models)

A water cooling tower installation does not require modification of the ice machine.

• Water pressure at the condenser cannot exceed 276 psig (1900 kPa).

• 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).

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 foot (2.5 cm per meter) of run 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.

• Install a tee at the ice machine drain outlet and install an 18" (46 cm) vent above the drain line.

• Drain termination must have an air gap that meets local code.

Auxiliary Base Drain Installation

An auxiliary drain is located in the ice machine base to remove moisture in high humidity areas.

1. View the back of the ice machine base

on the compressor side and locate and remove the cap plug.

2. Route tubing to an open site drain:

• Use 1/2 inch CPVC tubing.

• Apply a bead of silicone around the exterior of the ice machine tubing and insert into ice machine base. The silicone will secure the tubing and provide a watertight seal.

• Provide support for tubing.

CALCULATING INSTALLATION DISTANCES

Line Set Length

The maximum tubing length is 100 feet (30 meters).

Line Set Rise/Drop

The maximum rise is 35 feet (10.7 meters). The maximum drop is 15 feet (4.5 meters).

Notice

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 feet (45 meters).

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.

2. Insert the measured drop into the

formula below. Multiply by 6.6 to get the calculated drop.

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

26 Part Number: 000014141 Rev 05 11/18

Section 2 Installation

4. Add together the calculated rise, calculated drop, and horizontal distance to get the total calculated distance. If this total exceeds 150 feet

(45 meters), move the condenser/ condensing unit to a new location and perform the calculations again.

Notice

The refrigeration system warranty will not apply if the Manitowoc Ice Machine and Manitowoc CVD Condensing Unit are 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 approved by Manitowoc.

REMOTE CONDENSER MODELS Step 1 Secure the Condenser.

Through-holes are provided to secure the condenser to a curb, rack or wooden timber.

Warning

The ice machine head section contains refrigerant charge. The ice machine head section contains refrigeration valves that must remain closed until proper installation of the line sets is completed.

Warning

Electrical power to the ice machine head section, condensing unit or condenser must be disconnected before proceeding.

Step 2 Route the Refrigeration Tubing.

Route the refrigeration tubing between the ice machine head section and the condenser.

• Maximum line set exposed on rooftop is 25% of total line set length.

• A qualified person must perform all roof penetrations.

• Interconnecting wire must be routed between the ice machine and condenser.

Step 3 Connect the Line Set.

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 access valves. Use these valves to recover any vapor charge from the line set.

Part Number: 000014141 Rev 05 11/18 27

Installation Section 2

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 (145 grams) of vapor refrigerant charge in each line.

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, then tighten the couplings with a wrench until they bottom out.

4. Turn an additional quarter turn to ensure proper brass-to-brass seating. Torque to the following specifications:

Section 2 Installation

Remote Ice Machine Usage with NonManitowoc 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 only approval is for full warranty coverage to be extended to the Manitowoc manufactured part of the system. Since Manitowoc does not test the 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.

Important

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.

Design & Burst Pressure

Design Pressure 600 psig - 4137 kPa Burst Pressure 2500 psig - 17237 kPa

Head Pressure Control Valve

Do not use a fan cycling control to try to maintain discharge pressure. Compressor failure will result. Any remote condenser connected to a Manitowoc Ice Machine must have the OEM head pressure control valve installed. Manitowoc will not accept substitute “off the shelf” head pressure control valves.

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 multicircuit 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. Do not exceed internal volume and try to add charge to compensate, as compressor failure will result.

Section 3 Operation

Ice Making Sequence of Operation

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.

Water Purge Cycle

The ice machine purges any remaining water from the water trough down the drain.

Prechill Cycle

The refrigeration system cools the evaporator before the water pump is energized.

Freeze Cycle

Water flows across the evaporator and the refrigeration system chills the evaporator. Ice builds on the evaporator and the freeze cycle continues until the ice thickness probe senses a sheet of ice has formed. The ice thickness probe signals the control board to start a harvest.

Harvest Cycle

Any remaining water is purged down the drain as refrigerant gas warms the evaporator. When the evaporator warms, the sheet of cubes slides off the evaporator and into the storage bin. If all cubes fall clear of the water curtain (or ice damper) the ice machine starts another freeze cycle.

Off Cycle

If the water curtain or ice damper are held open by ice cubes the ice machine shuts off. When the water curtain or ice damper closes, the ice machine starts a new cycle at the water purge.

Control Board Timers

The control board has the following nonadjustable timers:

• The ice machine control board will set its own install date after 100 freeze and harvest cycles.

• The ice machine is locked into the freeze cycle for 6 minutes before a harvest cycle can be initiated.

• 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 water thaw cycle and then return the ice machine to the freeze cycle.

Service Faults

Service Faults are stored and indicated by the control board after three cycles. The number of cycles required to stop the ice machine varies for each Service Fault.

• Long Freeze Cycle - If the freeze time reaches 35 minutes, the control board automatically initiates a harvest cycle. If 6 consecutive 35 minute freeze cycles occur, the ice machine stops.

• Long Harvest Cycle - If the harvest time reaches 7 minutes, the control board automatically returns the ice machine to the freeze cycle. After 3 consecutive long harvest cycles the ice machine stops.

Refer to Section 5 if you receive an alert for Service Fault E01 or E02.

Part Number: 000014141 Rev 05 11/18 39

Operation Section 3

Safe Operation Mode

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

• When the control board starts the safe mode, an alert is flashed on the 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.

NOTE: 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.

Water Assist Harvest

Water Thaw Cycle

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

• 7 minutes - The compressor, harvest solenoid valve and dump valve deenergize.

1. The water pump remains energized

and the water inlet valve energizes until water touches the high water level probe.

2. Water is circulated over the

evaporator.

3. Water is circulated, dumped and

refilled to the high water level probe for approximately 1 hour.

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

When 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.

Ice Thickness Check

After a harvest cycle, inspect the ice cubes in the ice storage bin. The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (3 mm).

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 must be approximately 1/8" (3 mm) thick.

2. If adjustment is necessary, turn the ice thickness probe adjustment screw clockwise to increase bridge thickness, counterclockwise to decrease bridge thickness. Set a 7 mm (9/32") gap between ice thickness probe and evaporator as starting point, then adjust to achieve a 1/8" (3 mm) bridge thickness.

NOTE: Turning the adjustment one-third of a turn will change the ice thickness about 1/16" (1.5 mm).

Section 4 Maintenance

Cleaning the Air Filter and Condenser

The washable filter on self-contained ice machines is designed to catch dust, dirt, lint and grease. Clean the filter once a month with mild soap and water.

A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life.

Warning

Disconnect electric power to the ice machine at the electric service switch before cleaning the air filter or the condenser. The condenser fins are sharp; Use care when removing or installing the air filter.

• Clean the condenser at least every six months.

• Shine a flashlight through the condenser to check for dirt between the fins.

• Blow compressed air or rinse with water from the inside out (opposite direction of airflow).

• If dirt still remains, call a service agent to clean the condenser.

Removal from Service/Winterization

Service Faults

In addition to the standard safety controls, such as the high pressure cutout, your Manitowoc ice machine features builtin 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 display reads “Off”. Press the power button again, and the display reads “Making Ice”.

A. If a service fault has stopped the

ice machine, it will restart after a short delay. Proceed to step 2.

B. If the ice machine does not

restart, see “Ice machine does not operate” on page 51.

2. Allow the ice machine to run to determine if the condition repeats.

A. If the ice machine stops again, the

condition has repeated. Call for service.

B. If the ice machine continues to

run, the condition has corrected itself. Allow the ice machine to continue running.
