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 air-cooled 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.

Ice Machine Head Section Water

Important

Supply and Drains

POTABLE WATER SUPPLY

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

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.

POTABLE 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 inst alled for other equipment are working. (Check valves on sink faucets, dishwashers, etc.)

• If water pressure exceeds the maximum recommended pressure of 80 psig (5.5 Bar), obtain a water pressure regulator from your Manitowoc Distributor.

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

• Insulate water inlet lines to prevent condensation.

Part Number 80-1230-9 10/10 31

Page 32

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 in. (3.8 cm) drop per 5 ft. 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-cooled condenser drain lines. Insulate them to prevent condensation.

• Vent the bin drain to the atmosphere. Do not vent the condenser drain on water-cooled models.

• Drains must have a union or other suitable means to allow a place of disconnection from the ice machine when servicing is required.

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, (refer to page 25) 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 gal. (19 L) 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°C).

INSTALLING ON A DISPENSER

Warning

Caution

Nugget ice is soft and chewable. This characteristic makes this ice more difficult to dispense. All dispenser manufacturers require a kit be installed for Nugget type ice. Contact the dispenser manufacturer for the correct adapter and nugget dispensing kit for your specific model dispenser. The required kit can vary by dispenser size from the same manufacturer.

Failure to install the correct kit and make the necessary modifications on the dispenser will result in:

• Congealed ice which will not dispense and will damage the ice machine and dispenser

• Insufficient ice contact with the cold plate which will result in an inferior product

• A safety issue if ice lifts the adapter or ice machine

Nugget Dispensing Kit Installation Procedure

1. Follow the dispenser manufacturers instructions for installation of the adapter (if required) and nugget ice kit.

2. Make all necessary beverage, electrical and drain connections to the dispenser.

3. Level the dispenser front to back and side to side.

4. Install ice machine on dispenser and secure ice machine, dispenser and adapter with provided brackets.

5. Complete water, drain and electrical connections to the ice machine.

The ice machine and adapter must be attached to the dispenser to prevent the ice machine from falling.

Ice machines in low volume locations may experience congealing. Thermostat kit K00364 must be added in these locations to prevent damage to the ice machine and dispenser.

Manitowoc’s Cleaning Technology

Manitowoc Flake/Nugget Ice Machines allow the initiation and completion of a cleaning cycle at the flip of a switch. This cycle will permit cleaning of all surfaces that come in contact with the water distribution system. Periodic maintenance must be performed that includes sanitizing the bin and adjacent surface areas, which are not contacted by the water distribution system.

Depending on local water conditions Manitowoc recommends initiating preventative maintenance cleaning procedures between the 6 month cleanings. This preventive maintenance removes mineral buildup from the evaporator, which results in peak efficiency and lower operating costs.

This technology allows initiation and completion of a clean cycle, after which the ice machine automatically starts ice making again.

There are three separate cleaning procedures.

Heavily Scaled Cleaning Procedure

Perform this procedure if you have some or all of these symptoms.

• Grinding, popping or squealing noises from the evaporator.

• Grinding noise from gearbox.

• Ice machine trips speed sensor.

A Cleaning/Sanitizing Procedure must be performed after this procedure.

Cleaning/Sanitizing Procedure

This procedure must be performed a minimum of once every six months:

• All ice must be removed from the bin/dispenser.

• The ice machine and bin/dispenser must be disassembled, cleaned and sanitized.

• The ice machine produces ice with the cleaner and sanitizer solutions.

• All ice produced during the cleaning and sanitizing procedure must be discarded

44 Part Number 80-1230-9 10/10

Page 45

Preventative Maintenance Cleaning Procedure

Perform this procedure as often as required for your water conditions:

• Allows cleaning the ice machine without removing all of the ice from the bin/dispenser.

• Removes mineral deposits from areas that are in direct contact with water during the Freeze cycle (reservoir, evaporator, auger, drain lines).

EXTERIOR CLEANING

Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation. Use cleaners designed for use with stainless steel products.

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.

SN012/SN020 Only

WEEKLY Remove grill from scrap ice tray and wipe splash

panel, scrap ice tray and grill with sanitizer & water solution. Pour excess solution in scrap ice tray to clear drain.

TOUCHLESS SENSOR ONLY Wipe sensor window with a soft cloth and mild

detergent. Rinse with clear water and dry with a clean soft cloth.

Dust and dirt can be removed from exterior surfaces with mild household dish-washing detergent and warm water. Wipe dry with a clean, soft cloth.

WATER DUMP VALVE - ALL MODELS

Warning

The water dump valve normally does not require removal for cleaning. To determine if removal is necessary:

1. Set the toggle switch to OFF.

2. Watch the water float valve. If the dump valve is leaking the float will continue to add water in the Off cycle.

• If the dump valve is leaking, remove, disassemble and clean it.

• If the dump valve is not leaking, do not remove it. Instead, follow the “Cleaning Procedure”.

Follow the procedure below to remove the dump valve.

Disconnect the electric power to the ice machine at the electric service switch box and turn off the water supply before proceeding.

1. Depress and twist the coil 1/8 turn counterclockwise.

2. Leaving the wires attached, lift the coil assembly off the valve body.

3. Remove the plunger, nylon gasket and diaphragm from the valve body.

NOTE: At this point, the water dump valve can easily be cleaned. If complete removal is desired, continue with step 4.

CLEANING THE CONDENSER

Warning

Disconnect electric power to the ice machine at the electric service switch before cleaning the condenser. The condenser fins are sharp. Use care when cleaning them.

Air-Cooled 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.

1. The washable aluminum filter on self-contained ice machines is designed to catch dust, dirt, lint and grease. This helps keep the condenser clean. Clean the filter with a mild soap and water solution.

2. Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Clean from top to bottom, not side to side. Be careful not to bend the condenser fins.

3. Shine a flashlight through the condenser to check 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.

B. Use a commercial condenser coil cleaner.

Follow the directions and cautions supplied with the cleaner.

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

5. Carefully wipe off the fan blades and motor with a soft cloth. Do not bend the fan blades. If the fan blades are excessively dirty, wash with warm, soapy water and rinse thoroughly.

If you are cleaning the condenser fan blades with water, cover the fan motor to prevent water damage.
