Electrical Service
GENERAL
All wiring must conform to local, state and national codes.
VOLTAGE
The maximum allowable voltage variation is 10% of the rated voltage on the ice machine model/serial number plate at start-up (when the electrical load is highest).
The 115/1/60 ice machines are factory pre-wired with a 8’ power cord, and NEMA 5-15P-plug configuration.
The 208-230/1/60 and 230/50/1 ice machines are factory pre-wired with a 8’ power cord only, no plug is supplied.
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).
The ice machine must be grounded in accordance with national and local electrical codes.
TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the wire size of the electrical supply.
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.
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, Inc. does not recommend the use of a GFCI/GFI circuit protection with our equipment. If code requires the us e of a GF CI /G FI 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 n uisance trips than panel breakers.
PERSONAL INJURY POTENTIAL
If the supply cord is damaged, do not operate the equipment until the cord is replaced by a service agent or similarly qualified person.

Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, remove chlorine, and improve taste and clarity.
PERSONAL INJURY POTENTIAL
For ice making, connect to a potable water supply only .
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 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 (80 psig-551.5 kPA) recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.
Install a water shut-off valve and union 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 water-cooled condenser dra in lines. Insulate them to prevent condensation.
Vent the bin drai n 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 condenser must not exceed 90F (32C).
Water flow through the con denser must not exceed 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 (43C).
Part Number 040001358 05/10 7
The Commonwealth of Massachusetts requires that all water-cooled models must be connected only to a closed loop, cooling tower system.

Operation
Ice Making Sequence of Operation
INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF
1. Pressure Equalization
Before the compressor starts the hot gas valve is energized for 15 seconds to equalize pressures during the initial refrigeration system start-up.
2. Refrigeration System Start-Up
The compressor starts after the 15-second pressure equalization, and remains on throughout the entire Freeze and Harvest Sequences. The hot gas valve remains on for 5 seconds during initial compressor start­up 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 relay . As a result, any time the relay 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 starts after the 30-second Prechill. An even flow of water is directed across the evaporator and into each cube cell, where it freezes.
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 time has been surpassed.
HARVEST SEQUENCE
5. Harvest
The water pump de-energizes stopping flow over the evaporator. The rising level of water in the sump trough diverts water out of the overflow tube, purging excess minerals from the sump trough. The hot gas valv e also opens to divert hot refrigerant gas into the evaporator.
The refrigerant gas warms the evaporator causing the cubes to slide, as a sheet, off the evaporator an d into the storage bin. The sliding sheet of cubes contacts the ice damper, opening the bin switch.
The momentary opening and re-closing of the bin switch terminates the Harvest Sequence and returns the ice machine to the Freeze Sequence (steps 3 - 4).
AUTOMATIC SHUT-OFF
6. Automatic Shut-Off
When the storage bin is full at the end of a Harvest Sequence, the sheet of cubes fails to clear the ice damper and will hold it down. After the ice damper 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 damper. As the ice damper 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
Your Manitowoc ice machine was factory-operated and adjusted before shipment. Normally , a newly inst alled ice machine does not require any adjustment.
To ensure proper operation, always follow these Operational Checks when starting the ice machine:
for the first time
after a prolonged out of service period
after cleaning and sanitizing Routine adjustments and maintenance procedures
outlined in this manual are not covered by the warranty.
SIPHON SYSTEM
To reduce mineral build-up and cleaning frequency, the water in the sump trough must be purged during each harvest cycle.
When the water pump de-energizes the level in the water trough rises above the standpipe st artin g a siphon action. The siphon action stops when the water level in the sump trough drops. When the siphon action stops, the float valve refills the water trough to the correct level.
Siphon System Check
Follow steps 1 through 6 under water level check.
WATER FLOAT VALVE CHECK
Before water will flow into the water trough the float valve shut-off must be in the OPEN position.

1/8" ICE BRIDGE THICKNESS
WATER LEVEL CHECK
Check the water level while the ice machine is in the ice mode and the water pump is running. The correct water level is 1/4" (6.3mm) to 3/8" (9.5mm) below the top of the standpipe a line in the water trough indicates the correct level.
Water Level
The float valve is factory-set for the proper water level. If adjustments are necessary:
1. Verify the ice machine is level (see page 2-4).
2. Remove the siphon cap from the standpipe.
ICE BRIDGE THICKNESS CHECK
The ice thickness probe is factory-set to maintain th e ice bridge thickness at 1/8" (3.2 mm).
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, or counterclockwise to decrease bridge thickness.

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 pr od u ctio n an d 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.
A commercial grade stainless steel cleaner/polish can be used as necessary.
Cleaning the Condenser
GENERAL
Disconnect electric power to the ice m achine 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.
The condenser fins are sharp. Use care when cleaning them.
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
1. Clean and san itiz e th e ice ma ch in e.
2. Move the ICE/OFF/CLEAN switch to OFF.
3. Turn off the water supply, disconnect and drain the incoming ice-making water line at the rear of the ice machine and drain the water trough.
4. Energize th e ice ma ch in e, wa it one min ut e fo r the water inlet valve to open and blow compressed air in both the incoming water and the drain openings in the rear of the ice machine to remove all water.
5. Move ICE/OFF/CLEAN switch to OFF and disconnect the electric power at the circuit breaker or the electric service switch.
6. Fill spray bottle with sanitizer and spray all interior food zone surfaces. Do not rinse and allow to air dry.
