Ice Machine Location

The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location.

• The ice machine may be built into a cabinet, however the location must allow removal of the ice machine for cleaning and servicing. Service diagnostics are performed from the top of the ice machine. Refer to "Minimum Cut-Out For Built-In Installations" on page 9.
• The location must be free of airborne and other contaminants.
• The air temperature must be at least 50^ (10^) , but must not exceed 100^ (38^) .
• The location must not be near heat-generating equipment.
• The location must not obstruct air flow through the condenser (airflow is in and out the front of the ice machine).
• The location must allow enough clearance for water, drain and electrical connections at the rear of the ice machine.

Caution

The ice machine must be protected if it will be subjected to ambient temperatures below 32^ (0^) . Component failure caused by exposure to freezing temperatures is not covered by the warranty.

ElectricalService

Prepare electrical circuit before installation of your ice machine. Installation requires a grounded (three-prong), polarized receptacle with a separate fuse/circuit breaker in an electrical service box.

VOLTAGE

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

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.
• 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.
• Manitowoc's recommended minimum wire size is #14 for less than 100^ or #12 for more than 100^ to 200^ (solid copper conductor only). The recommended breaker is 15 amp. Local or state electrical code, length of run or materials used, can increase the minimum wire gauge required. A qualified electrician must determine the proper wire size, although #14 is the minimum size allowed.
• Incorrect polarity can lead to erratic ice machine operation and a safety issue.

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.)

GFCI REQUIREMENTS

If GFCI (ground fault circuit interrupter) is required by local electrical code, it must be breaker type.

Water Supply and Drain Requirements

WATERSUPPLY

Prepare water supply line and drain before installation of your ice machine. Installation requires a 1/4'' ID copper cold water line and compression fitting (not supplied). The ice machine is supplied with a drain hose for gravity draining. The optional drain pump must be purchased if a gravity drain is not possible. Both drain methods require routing to an open site drain. Do not connect directly to drain line as bacteria from drain line may contaminate the ice machine.

The included water filter is designed to inhibit scale formation, filter sediment, and remove chlorine odor and taste. The life expectancy of the water filter is 6 months during normal usage. The ice machine control board will monitor water usage and indicate when replacement is required.

WATER INLET LINES

Follow these guidelines to install water inlet lines:

• Plumbing must conform to state and local codes.
• 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.)
• Water pressure must remain between 20 and 80 psig (14 to 55 bar). If water pressure exceeds the maximum recommended pressure (80 psi - 55 bar), obtain a water pressure regulator from your Manitowoc distributor.
• Install a water shut-off valve for the ice making water lines.
• Insulate the water inlet line 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.
• Drain pump discharge line must terminate at an open site drain

Sequence of Operation

Depending on ambient conditions and cold water supply temperature, the ice making process will take approximately 15-30 minutes.

Step 1 Initial Start-Up or

Start-Up After Automatic Shut-Off: Water Purge/Refrigeration Equalization

Before the compressor starts, the harvest valve and dump valve will energize for 15 seconds to equalize pressure in the refrigeration system and purge old water from the system.

Step 2 Refrigeration System Start-Up - Prechill

The compressor, condenser fan motor, liquid line solenoid and water inlet valve energize. The prechill cycle continues until the water trough fills (float valve opens) and the 30 second minimum prechill time expires.

Step 3 Freeze

The water pump energizes and sprays water onto the evaporator. The water freezes on the evaporator, dropping the water trough level until the low water float closes, ending the freeze cycle.

Step 4 Harvest

The water pump and water inlet valve remain on for 45 seconds, then shutoff. The evaporator is warmed, allowing the cubes to release from the evaporator and drop into the storage bin. As the cubes drop into the bin a 60 second timer starts. The harvest cycle ends when the 60 second timer expires.

• When the bin is not full of ice the control will start a new prechill cycle (step 2).
• When the bin is full of ice the control initiates step 5 automatic shutoff.

Step 5 Automatic Shut-Off

The level of ice in the storage bin controls the ice machine shut-off. When the bin is full, ice will either contact the bin thermistor or hold the water curtain open, which stops the ice machine. The ice machine remains off until ice no longer contacts the bin thermistor and/or the water curtain. The increase in temperature will restart the ice machine (step 1).

Service Limits

Service limits protect the machine from major system failures. The service LED will flash when one of the five service limits are exceeded. When the service button is pressed the LED will flash the corresponding number for the fault condition. For example if service limit 2 occurs the service light will flash twice. Only the most recent service limit is saved to memory.

SERVICE LIMIT 1 LONG FREEZE CYCLE

The maximum freeze time is 30 minutes at which time the control board automatically initiates a harvest cycle (step 4).

SERVICE LIMIT 2 LONG HARVEST CYCLE

The maximum harvest time is 7 minutes at which time the control board either starts a prechill cycle (step 2) or enters automatic shutoff (step 4).

SERVICE LIMIT 3 WATER LOSS

In the Prechill cycle (step 2) when the high and low water level float switches do not open within 4 minutes the ice machine stops.

SERVICE LIMIT 4 CONDENSATE PUMP FAULT

When the float switch on the condensate pump is open or the float switch jumper is disconnected from the wire harness the ice machine stops.

SERVICE LIMIT 5 FULL BIN FAULT

When power is on and the ice machine has remained off for 24 hours the service LED will flash.

Refer to "Troubleshooting" on page 23 for further service limit detail.

Tongs, Tong Holder, Water Curtain, Ice Ramp, Water Pump, and Spray Nozzle Assembly. Refer to "Removal of Parts for Descaling/Sanitizing" on page 20 for identification.

Step 9 Take all removed components to a sink for descaling. Use 1/2 of the descaler/water mixture to descale all components. The solution will foam when it contacts lime scale and mineral deposits; once the foaming stops, use a soft-bristle nylon brush, sponge or cloth (NOT a wire brush) to carefully clean the parts.

Step 10 Place floats in a small container filled with descaler water solution to soak.

Step 11 While components are soaking, use the other 1/2 of the descaler/water solution and a nylon brush or cloth to clean inside the ice bin. Clean inside of door, door gasket, bin, and evaporator bucket. Rinse all areas thoroughly with clean water

Step 12 Mix 1 oz (2 tablespoons) sanitizer with 2 gal of warm water.

Model Sanitizer Amount Water Amount

USE0050 1 oz (30ml) 2 gal (8L)

Step 13 Remove floats from container, empty container and rinse floats and container with clean water. Fill container with sanitizer water solution and place floats in container to soak. Soak floats for 10 minutes then remove. Do not rinse sanitized floats.

Step 14 Use 1/2 of the sanitizer/water mixture to sanitize all removed components. Use a spray bottle, cloth or sponge to liberally apply the solution to all surfaces of the removed parts or soak the removed parts in the sanitizer/solution. Do not rinse sanitized components.

Step 15 Use the other 1/2 of the sanitizer/water solution and a spray bottle, sponge or cloth to sanitize the inside of ice bin. Sanitize inside of door, door gasket, bin and evaporator bucket. Do not rinse sanitized areas.

Step 16 Replace all removed components.

Step 17 Reapply power to the ice machine, then press the Clean button. Wait until the water pump sprays water onto the evaporator (approximately 3 minutes) then add 1/2 oz (1 tablespoon) of undiluted Manitowoc Sanitizer by lifting the water curtain and pouring directly into the spray area. This entire cycle lasts approximately 30 minutes. When the clean cycle is complete the ice machine will start a freeze cycle.

7. Turn on the water and electrical supply

TOP COVER

1. Disconnect power to the ice machine.
2. Remove two back screws.
3. Slide top cover backward slightly and lift cover off.

WATERCURTAIN

The water curtain is designed to keep the spraying water from escaping the evaporator compartment.

TO REMOVE JUST THE WATER CURTAIN:

1. Grasp one end of the water curtain and lift up.
2. Pivot water curtain and disengage remaining end.
3. To re-install into ice machine, grasp one end of the water curtain, install one end, pivot the opposite end and pull down into position. Make sure tabs are secure in grooves.

TO REMOVE WATER CURTAIN ASSEMBLY:

1. Slide evaporator bucket forward 1/2'' (13 mm).
2. Lift curtain assembly straight up.

Warning

Removing the water curtain while the water pump is running will allow water to spray from ice machine. Disconnect electrical power to the ice machine at the electric service switch box and turn off the water supply.

ICE CHUTE

The ice chute is positioned over the spray nozzles and allows the ice to easily fall into the bin. It must be firmly positioned over the spray bar, with the front edge inside the water trough. Spray nozzles must be align with the spray holes or spray water will fall into the bin.

1. Grasp and lift up and forward to remove.
2. Reverse procedure to re-install ice chute and reposition over the Water Distribution Assembly.

Make sure rear supports are over spray bar, and front edge is inside of water trough.

WATER TROUGH

1. Depress tabs on right and left side of the water trough.
2. Allow front of water trough to drop as you pull forward to disengage the rear pins.

SPRAY BAR, WATER PUMP AND HOSE

1. Remove spray bar clamp and spray bar.
2. Remove the 5 / 16'' water pump mounting screw.
3. Grasp pump and pull straight down until water pump disengages and electrical connector is visible.
4. Disconnect the electrical connector.
5. Remove the water pump from ice machine.
6. Remove clamp from hose to remove from pump.
7. Do not soak the water pump in descaler or sanitizer. Wipe the pump and ice machine base clean.

SPRAY BAR DISASSEMBLY

The spray bar supplies water to the individual ice making cups. Water from the water pump sprays through the nozzles, located on the upper portion of the tubes.

1. Grasp one end of the spray bar, lift up and remove from seat formed in evaporator bucket.
2. Remove clamp on water inlet tubing by grasping both ears on clip and separating.
3. Apply food grade lubricant to ease re-assembly of spray bar components when necessary.
4. To re-install spray bar, position water inlet tubing on inlet ports, and squeeze clips until tight.
5. Reposition assembly on water trough seat.

Nozzles and inserts can be removed for cleaning by unscrewing nozzles. Inserts are located inside the spray bar ports. The spray bar also disassembles for easy cleaning.

BIN LIGHT

If the ice machine is shut down for a long period of time the bin light cover must be cleaned and sanitized. The light is provided for your convenience. If you experience operational problems with the light a replacement appliance bulb can be obtained from your local hardware store.

WATER FILTER

To replace the water filter incoming water does not need to be turned off. This system is equipped with an internal shut-off valve.

1. Turn cartridge slowly to the left, about 1/4 turn, until it stops. At this position, both inlet and outlet ports are closed and water pressure has been relieved.
2. Pull used cartridge forward to remove, then discard. There may be a small amount of residual water drainage after pressure is relieved and during cartridge removal.
3. Remove cap from top of new cartridge and push new cartridge into filter head. Turn cartridge 1/4 turn to the right until it stops. Top surface of cartridge will become flush with bottom of the head when fully engaged.
4. Run a 3-minute fill cycle of the ice machine to flush the filter. Then power off unit and restart to begin a new fill sequence and ice making cycle.
5. Press and hold the "Clean" button for 6 seconds to reset the counter and de-energize the filter light.

ICE MACHINE INSPECTION

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.) in front 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.

Clean up any fallen ice or water spills as they occur.

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.
• Shine a flashlight through the condenser to check for dirt between the fins.
• Compressed air can be blown through the condenser fins. This procedure will raise considerable dust and is best performed outside. Be careful not to bend the fan blades.
• If dirt or grease remains between the fins or the condenser fins are bent or flattened, consult your service representative.

Removal from Service/Long Term Storage/Winterization

1. Perform a cleaning and sanitizing procedure to prevent mildew growth.
2. Disconnect the electric power at the circuit breaker or the electric service switch.
3. Turn off the water supply.
4. Remove the water from the water trough.
5. Disconnect and drain the incoming ice-making water line at the rear of the ice machine.
6. Disconnect vinyl hose from water pump and allow to drain.
7. Make sure water is not trapped in any of the water or drain lines. Compressed air can be used to blow out the lines.
8. Use a spray bottle and a solution of sanitizer/water (0.50 oz/1 gal) and spray all interior surfaces. Do not rinse, allow to air dry.
