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 -c on ta ine d 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 am ount of heat add ed 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.

Section 2 Installation Instructions

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 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 wate r 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-off valve 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 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.

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 co ndenser must not exceed 90°F (32.2°C).

• Water flow th rough the condenser m ust not e xceed 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).

First, cut a 2.5" (63.5 mm) circular hole in t he wall or ro of for tubing routing. The line set en d 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 insure proper performance and service accessibility.

1. Optional - Make the service loop in the line sets (See 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 re frigeration 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 (See 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' (30.5 m). The ice machine compressor must have the proper oil

return. The receiver is designed to hold a char ge sufficient to operate the ice machine in ambient temperatures between -20°F (-28.9°C) and 120°F (49°C), with line set lengths of up to 100' (30.5 m).

Line Set Rise/Drop

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

Caution

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 distance is 150' (45.7 m). Line set rises, drops, ho rizontal runs (or combina tions 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 mak e sure the line set layout is within specifications.

1. Insert th e 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 th e measured drop into the formula below. Multiply by 6.6 to get the calculated drop. (Example. A condenser located 10 f eet below t he ice machine has a calculated drop of 66 feet.)

3. Insert th e 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' (45.7 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, b y routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so bef ore con necting the lin e 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 and insulate new tubing. Do not change the tube sizes. Evacuate the lines and place a bo ut 5 oz (1 43 g) 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.

Section 2 Installation Instructions

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, Inc. Performance may vary from Sales specifications. Q-Model ARI certified standard ratings only apply when used with a Manito woc remote condenser.

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

only approval is f or full w arranty cov erage to

not test the condenser in

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.

HEAD PRESSURE CONTROL VALVE

Any remote condenser connected to a Manitowoc QModel Ice Machine must have a head pressure control valve #836809 -3 (a v ailab le from Ma nitow oc Distributors) installed on the condenser package. 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 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 dr op 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.)

Caution

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

Caution

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

Part No. 80-1375-3 2-17

QUICK CONNECT FITTINGS

The ice machine and line sets come with quick connect fittings. It is recommended th at matching q uic k connects (availab le through Manitow oc Distributors) be installed in the multi-circuit condenser, and that a vapor “holding” charge (5 oz.) of proper refrigerant be added to the condenser prior to connection of the ice machine or line set to the condenser.

INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-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 hot gas 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.

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. It remains on until the water level sensor closes for 3 continuous seconds, or until a six-minute time period has expired.The hot gas valve(s) remains on for 5 seconds during initial compressor start-up and then shuts off.

At the same time the compressor starts, the condenser fan motor (air-cooled models) 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 prior to water flow, to prechill the evaporator.

4. Freeze

The water pump restarts after the 30 second 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 7 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.

HARVEST SEQUENCE

5. Water Purge

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 the 45-second water purge. The water purge setting of 45 seconds for the fill valve to energize during the last 15 seconds of the Water Purge. If set at less than 45 seconds the water fill valve does not energize during the water 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.) The hot gas valve also opens at the beginning of the water purge to divert hot refrigerant gas into the evaporator.

6. Harvest

The hot gas 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 reclosing of the bin switch terminates the harvest sequence and returns the ice machine to the freeze sequence (Step 3 - 4.)

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 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 water curtain. As the water curtain swings back to the operating position, the bin switch re-closes and the ice machine restarts (steps 1 - 2), provided the 3 minute delay period is complete.

Operational Checks

GENERAL

Manitowoc ice machines are factory-operated and 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.). Repair or replace the probe as necessary.

ICE THICKNESS CHECK

The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (3.2 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 should be about 1/8" (3.2 mm) thick.

2. If adjustment is necessary, turn the ice thickness probe adjustment screw clockwise to increase bridge thickness, counterclockwise to decrease bridge thickness.

NOTE: Turning the adjustment 1/3 of a turn will change the ice thickness about 1/16" (1.5 mm).

HARVEST SEQUENCE WATER PURGE

The harvest sequence water purge adjustment may be used when the ice machine is hooked up to special water systems, such as a de-ionized water treatment system.

Important

The harvest sequence water purge is factory-set at 45 seconds. A shorter purge setting (with standard water supplies such as city water) is not recommended. This can increase water system cleaning and sanitizing requirements.

• The harvest sequence water purge may be set to 15, 30, or 45 seconds.

• During the harvest sequence water purge, the water fill valve energizes and de-energizes by time. The water purge must be at the factory setting of 45 seconds for the water fill valve to energize during the last 15 seconds of the water purge. If it is set to less than 45 seconds, the water fill valve will not energize during the water purge.

Maintenance

General

You are responsible for maintaining the ice machine in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty.

Warning

If you do not understand the procedures or the safety precautions that must be followed, call your local Manitowoc service representative to perform the maintenance procedures for you.

We recommend that you perform the following maintenance procedures every six months to ensure reliable, trouble-free operation and maximum ice production.

Ice Machine Inspection

Warning

Disconnect electric power to the ice machine and the remote condensing unit at the electric service switch before cleaning the condenser.

Check all water fittings and lines for leaks. Also, make sure the refrigeration tubing is not rubbing or vibrating against other tubing, panels, etc.

Do not put anything (boxes, etc.) on the sides or back of the ice machine. There must be adequate airflow through and around the ice machine to maximize ice production and ensure long component life.

Exterior Cleaning

Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation.

Sponge any dust and dirt off the outside of the ice machine with mild soap and water. Wipe dry with a clean, soft cloth.

Heavy stains should be removed with stainless steel wool. Never use plain steel wool or abrasive pads. They will scratch the panels.

Part No. 80-1640-3 4-1

Maintenance Section 4

Cleaning the Condenser

GENERAL

3. Straighten any bent condenser fins with a fin comb.

Warning

Disconnect electric power to the ice machine head section and the remote condensing unit at the electric service switches before cleaning the condenser.

A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life. Clean the condenser at least every six months. Follow the steps below.

Warning

The condenser fins are sharp. Use care when cleaning them.

1. Clean the outside of the condenser with a sof t bru sh or a vacuum with a brush attachment. Be careful not to bend the condenser fins.

2. Shine a flashlight through the conden se r to che ck for dirt between the fins. If dirt remains:

A. Blow compressed air through the condenser fins

from the inside. Be careful not to bend the fan blades.

Section 4 Maintenance

WATER-COOLED CONDENSER AND WATER REGULATING VALVE

Symptoms of restrictions in the condenser water circuit include:

• Low ice production

• High water consumption

• High operating temperatures

• High operating pressures If the ice machine is experiencing any of these symptoms,

the water-cooled condenser and water regulating valve may require cleaning due to scale build-up.

The cleaning procedures require special pumps and cleaning solutions. Follow the manufacturer’s instructions for the specific cleaner being used.

MANITOWOC’S PATENTED CLEANING OR SANITIZING TECHNOLOGY

Manitowoc Ice Machines include technology that allows the initiation and completion of a cleaning or sanitizing cycle at the flip of a switch. This cycle will permit cleaning or sanitizing of all surfaces that come in contact with the water distribution system. Periodic maintenance must be performed that includes sanitizing the bin (or dispenser) and adjacent surface areas, which cannot be contacted by the water distribution system.

This technology will also allow initiation and completion of a clean or sanitize cycle, after which the ice machine automatically starts ice making again.

Refer to the cleaning or sanitizing procedure for complete details.

The AuCS Accessory can be set to automatically start and finish a clean or sanitize cycle every 2, 4, or 12 weeks. This accessory monitors ice-making cycles and initiates a cleaning or sanitizing cycle automatically. Refer to Automatic Cleaning System (AuCS) Accessory for further details.

ALPHASAN

The goal of AlphaSan is to keep the plastic surfaces of an ice machine cleaner, by reducing or delaying the formation of bio-film. The active ingredient in AlphaSan is the element silver in the form of silver ions (Ag+). AlphaSan slowly releases silver ions via an ion exchange mechanism. When AlphaSan is compounded directly into a plastic part, a controlled release of silver ions from the surface is regulated to maintain an effective concentration at or near the surface of the plastic ice machine part. AlphaSan’s unique ability to effectively control the release of silver not only protects against undesired discoloration of the plastic, but also will last the life of the plastic part. Although AlphaSan helps prevent bio-film build up it does not eliminate the need for periodic cleaning and maintenance. AlphaSan has no adverse effect on the taste of the ice or beverage.

Part No. 80-1640-3 4-3

Maintenance Section 4

Interior Cleaning and Sanitizing

GENERAL

Clean and sanitize the ice machine every six months for efficient operation. If the ice machine requires more frequent cleaning and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment or installation of AuCS required, an extremely dirty ice machine may be taken apart for cleaning and sanitizing.

AUTOMATIC CLEANING SYSTEM (AuCS®)

This accessory monitors ice making cycles and initiates cleaning (or sanitizing) procedures automatically. The

AuCS

Accessory can be set to automatically clean or

sanitize the ice machine every 2, 4, or 12 weeks.

Caution

Refer to the AuCS® Accessory Installation - Use and Care Manual for complete details on the installation, operation, maintenance and cautionary statements of this accessory.

Automatic Operation

The following occurs when the toggle switch is in the ICE position:

• The ice machine control board counts the number of ice harvest cycles.

•The AuCS

accessory interrupts the ice making mode and starts the cleaning (or sanitizing) mode when the harvest count equals the “Frequency of Cleaning” setting of the AuCS

• When the automatic cleaning (or sanitizing) cycle is complete (approximately 25 minutes), ice making resumes automatically, and the “Harvest Count” is reset to zero.

Important

Opening the curtain switch will interrupt the cleaning or sanitizing sequence. The sequence will resume from the point of interruption when the curtain recloses.

Manual Start Operation Step 1 Set the toggle switch to the OFF position after

ice falls from the evaporator at the end of a Harvest cycle. Or, set the switch to the OFF position and allow the ice to melt off the evaporator.

Caution

Never use anything to force ice from the evaporator. Damage may result.

Step 2 To start the automatic cleaning system, move the toggle switch to the CLEAN position. The water will flow through the water dump valve and down the drain. The Clean light will turn on to indicate the ice machine is in the Self Cleaning mode. The AuCS

then automatically adds cleaner or sanitizer to the ice machine.

Step 3 The ice machine will automatically time out a ten minute cleaning or sanitizing cycle, followed by six rinse cycles, (de-energize the Clean light) and stop. This entire cycle lasts approximately 25 minutes.

Step 4 After the cleaning or sanitizing cycle stops, move the toggle switch to ICE position.

Step 5

A. The ice machine may be set to start and finish a

cleaning or sanitizing cycle, then automatically start ice making again.

B. You must wait about one minute into the

cleaning cycle (until water starts to flow over the evaporator), then move the toggle switch from CLEAN to ICE position.

4-6

C. When the cleaning or sanitizing cycle is

completed, the clean light will turn off and an ice making sequence will start automatically.
