The location must be indoors.
The location must be free of airborne and other
contaminants.
•
•
•
•
The air temperature must be at least 40°F (4.4°C),
but must not exceed 110°F (43.4°C).
* B.T.U./Hour
** Because the heat of rejection varies during the ice making cycle, the
figure shown is an average.
The location must not be near heat-generating
equipment or in direct sunlight.
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.
The location must be capable of supporting the
weight of the ice machine and a full bin of ice.
The location must allow enough clearance for water,
drain and electrical connections in the rear of the ice
machine.
•
The location must not obstruct airflow through or
around the ice machine (condenser airflow is in and
out the front). Refer to the chart below for clearance
requirements.

Installation Instructions
Section 2
TOTAL CIRCUIT AMPACITY
Electrical Service
The total circuit ampacity is used to help select the wire
size of the electrical supply.
GENERAL
!
Warning
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.
All wiring must conform to local, state and national
codes.
GROUND FAULT CIRCUIT INTERUPTER
VOLTAGE
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,
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).
presumably to ground. Manitowoc Ice, Inc. does not
recommend the use of a GFCI/GFI circuit protection with
our equipment. If code requires the use of a GFCI/GFI
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 nuisance
trips than panel breakers.
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).

Warning
PERSONAL INJURY POTENTIAL
If the supply cord is damaged, do not operate the

Installation Instructions
DRAIN CONNECTIONS
Water Service/Drains
Follow these guidelines when installing drain lines to
prevent drain water from flowing back into the ice
machine and storage bin:
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, remove
chlorine, and improve taste and clarity.
•
•
•
•
Drain lines must have a 1.5 inch drop per 5 feet of
run (2.5 cm per meter), and must not create traps.
!
Warning
The floor drain must be large enough to
accommodate drainage from all drains.
PERSONAL INJURY POTENTIAL
For ice making, connect to a potable water supply
only.
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.
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.
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.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
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.
•
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 entering the condenser must not exceed 90°F
(32.2°C).
•
If water pressure exceeds the maximum
(80 psig-551.5 kPA) recommended pressure, obtain
a water pressure regulator from your Manitowoc
distributor.
Water flow through the condenser must not exceed 5
gallons (19 liters) per minute.
•
•
Install a water shut-off valve and union for both the
ice making and condenser water lines.
Allow for a pressure drop of 7 psi (48 kPA) between
the condenser water inlet and the outlet of the ice
machine.
Insulate water inlet lines to prevent condensation.
•
Water exiting the condenser must not exceed 110°F
(43.3°C).
Important
The Commonwealth of Massachusetts requires
that all water-cooled models must be connected
only to a closed loop, cooling tower system.

Operation
Section 3
Ice Making Sequence of Operation
INITIAL START-UP OR START-UP AFTER
AUTOMATIC SHUT-OFF
HARVEST SEQUENCE
5. Harvest
1. Pressure Equalization
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 valve also
opens to divert hot refrigerant gas into the evaporator.
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 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 contacts the ice
damper, opening the bin switch.
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 start-
up and then shuts off.
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).
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
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.
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.
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.
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.

WATER LEVEL CHECK
ICE BRIDGE THICKNESS 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.
The ice thickness probe is factory-set to maintain the 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.

Maintenance
CLEANING THE CONDENSER
Water-Cooled Condenser and
Water Regulating Valve
The water-cooled condenser and water regulating valve
may require cleaning due to scale build-up.
!
Warning
Disconnect electric power to the ice machine at
the electric service switch before cleaning the
condenser.
Low ice production, high water consumption and high
operating temperatures and pressures all may be
symptoms of restrictions in the condenser water circuit.
Air-Cooled Condenser
Because the cleaning procedures require special pumps
and cleaning solutions, they must be performed by
qualified maintenance or service personnel.
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. 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: Blow
compressed air through the condenser fins from the
inside. Be careful not to bend the fan blades.
4. Use a commercial condenser coil cleaner. Follow
the directions and cautions supplied with the
cleaner.
5. Straighten any bent condenser fins with a fin comb.
6. 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.
Caution
!
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water
damage.

SAFETY LIMITS
General
Determining Which Safety Limit
Stopped The Ice Machine
When a safety limit condition causes the ice machine to
stop, the harvest light on the control board continually
flashes on and off. Use the following procedures to
determine which safety limit has stopped the ice
machine.
In addition to standard safety controls, the control board
has two built in safety limit controls which protect the ice
machine from major component failures.
Safety Limit #1: If the freeze time reaches 60 minutes,
the control board automatically initiates a harvest cycle.
If three consecutive 60-minute freeze cycles occur, the
ice machine stops.
1. Move the toggle switch to OFF.
2. Move the toggle switch back to ON.
3. Watch the harvest light. It will flash one or two times,
corresponding to safety limits 1 and 2, to indicate
which safety limit stopped the ice machine.
Safety Limit #2: If the harvest time reaches 3.5
minutes, the control board automatically returns the ice
machine to the freeze cycle. If three consecutive 3.5
minute harvest cycles occur, the ice machine stops.
After safety limit indication, the ice machine will restart
and run until a safety limit is exceeded again.
Safety Limit Stand-By Mode:
Safety Limit Notes
The first time a safety limit shut down occurs, the ice
machine turns off for 60 minutes (Stand-by Mode). The
ice machine will then automatically restart to see if the
problem reoccurs. During the Stand-By Mode the
harvest light will be flashing continuously and a safety
limit indication can be viewed. If the same safety limit is
reached a second time (the problem has reoccurred) the
ice machine will initiate a safety limit shut down and
remain off until it is manually restarted. During a safety
limit shut down the harvest light will be flashing
continuously.
•
A safety limit indication is completed before the water
pump starts. Water contacting the ice thickness
probe in the freeze cycle will cause the harvest light
to flash. Do not mistake a harvest light flashing in the
freeze cycle with a safety limit indication.
•
•
•
A continuous run of 100 harvests automatically
erases the safety limit code.
The control board will store and indicate only one
safety limit – the last one exceeded.
If the toggle switch is moved to the OFF position and
then back to the ON position prior to reaching the
100-harvest point, the last safety limit exceeded will
be indicated.
•
If the harvest light did not flash prior to the ice
machine restarting, then the ice machine did not stop
because it exceeded a safety limit.
