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 90F
(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 110F
(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.

Section 3
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.

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.
NOTE: Turning the adjustment 1/3 of a turn will change
the ice thickness about 1/16" (1.5 mm).
3. Place the main ON/OFF/WASH toggle switch to the
ON position, and wait until the float valve stops
adding water.
4. Adjust the water level to (1/4" to 3/8" (6.3 to 9.5 mm)
below the standpipe) the line in the water tr ough:
5. Loosen the two screws on the float valve bracket.
6. Raise or lower the float valve assembly as
necessary, then tighten the screws.
7. Move the main ON/OFF/ WASH toggle switch to the
OFF position. The water level in the trough will rise
above the standpipe and run down the drain.
8. Replace the siphon cap on the standpipe, and verify
water level and siphon action by repeating steps 3
through 5.
Ice Thickness Check
Make sure the ice thickness probe wire and the brac ket
do not restrict movement of the probe.

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
