Location of Ice Machine
The location selected for the ice machine must meet the
following criteria. If any of these criteria are not met,
select another location.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 35°F (1.6°C),
but must not exceed 110°F (43.4°C).
• The location must not be near heat-generating
equipment or in direct sunlight and must be protected
from weather.
• The location must not obstruct air flow through or
around the ice machine. Refer to the chart below for
clearance requirements.
Ice Machine Heat of Rejection
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.

Top/Sides 8" (20.3 cm)
Back 5" (12.7 cm)
*There is no minimum clearance required for water-cooled or
remote ice machines. This value is recommended for efficient
operation and servicing only.
!
Caution
The ice machine must be protected if it will be
subjected to temperatures below 32°F (0°C).
Failure caused by exposure to freezing
temperatures is not covered by the warranty. See
“Removal from Service/Winterization”.

Electrical Service
GENERAL
VOLTAGE
The maximum allowable voltage variation is ±10% of the
rated voltage at ice machine start-up (when the electrical
load is highest).
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).
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.)
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.
ELECTRICAL REQUIREMENTS
Refer to Ice Machine Model/Serial Plate for voltage/
amperage specifications.
S Series Ice Machines (* indicates preliminary data)
!
Warning
All wiring must conform to local, state and national
codes.

Water Supply and Drain Requirements
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
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
recommended pressure, obtain a water pressure
regulator from your Manitowoc distributor.
• Install a water shut-off valve 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 ice machine drain lines.
Insulate them to prevent condensation.
• Vent the bin and ice machine drain to the
atmosphere. Do not vent the condenser drain on
water-cooled models.
Cooling Tower Applications
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
(32.2°C).
• Water flow through the condenser 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
(43.3°C).
Important
If you are installing a Manitowoc Arctic Pure™water
filter system, refer to the Installation Instructions
supplied with the filter system for ice making water
inlet connections.
!
Caution
Do not apply heat to water valve inlet fitting. This will
damage plastic valve body.

Ice Machine Operation Section 3
3-2 Part Number 80-1629-3
Sequence Of Operation
NOTE: The toggle switch must be in the ice position and
the water curtain must be in place on the evaporator
before the ice machine will start.
INITIAL START-UP OR START-UP AFTER
AUTOMATIC SHUT-OFF
1. Water Purge
Before the compressor starts, the water pump and water
dump solenoid are energized for 45 seconds, to
completely purge the ice machine of old water. This
feature ensures that the ice making cycle starts with
fresh water.
The harvest valve(s) is also energized during water
purge, although it stays on for an additional 5 seconds
(50 seconds total on time) during the initial refrigeration
system start-up.
When Used - The air compressor energizes for the last
10 seconds of the cycle.
2. Refrigeration System Start-Up
The compressor starts after the 45 second water purge,
and it remains on throughout the entire Freeze and
Harvest Sequences. The water fill valve is energized at
the same time as the compressor. The harvest valve(s)
remains on for 5 seconds during initial compressor start-
up 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 contactor. As a result, anytime the contactor coil is
energized, the compressor and fan motor are supplied
with power.)
FREEZE SEQUENCE
3. Prechill
The compressor is on for 30 seconds (60 seconds initial
cycle) prior to water flow, to prechill the evaporator. The
water fill valve remains on until the water level probe is
satisfied.
4. Freeze
The water pump restarts after the prechill. An even flow
of water is directed across the evaporator and into each
cube cell, where it freezes. The water fill valve will cycle
on and then off one more time to refill the water trough.
When sufficient ice has formed, the water flow (not the
ice) contacts the ice thickness probe. After
approximately 10 seconds of continual water contact,
the harvest sequence is initiated. The ice machine
cannot initiate a harvest sequence until a 6 minute
freeze lock has been surpassed.
NOTE: Freeze lock is bypassed after moving the toggle
switch from OFF to ICE position for the first cycle only.

Section 3 Ice Machine Operation
Part Number 80-1629-3 3-3
HARVEST SEQUENCE
5. Water Purge
The harvest valve(s) opens at the beginning of the water
purge to divert hot refrigerant gas into the evaporator.
The water pump continues to run, and the water dump
valve energizes for 45 seconds to purge the water in the
sump trough. The water fill valve energizes (turns on)
and de-energizes (turns off) strictly by time. The water fill
valve energizes for the last 15 seconds of the 45-second
water purge.
After the 45 second water purge, the water fill valve,
water pump and dump valve de-energize. (Refer to
“Water Purge Adjustment” for details.)
6. Harvest
The harvest valve(s) remains open and 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 swings the water curtain out,
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 (Step 3 - 4.)
When Used - The air compressor energizes after 35
seconds and remains energized throughout the entire
harvest cycle. The air compressor will automatically
energize for 60 seconds when the harvest cycle time
exceeded 75 seconds in the previous cycle.
AUTOMATIC SHUT-OFF
7. Automatic Shut-Off
When the storage bin is full at the end of a harvest
sequence, the sheet of cubes fails to clear the water
curtain and will hold it open. After the water curtain is
held open for 30 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 water curtain. As the water curtain 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.
SAFETY TIMERS
The control board has the following non-adjustable
safety timers:
• The ice machine is locked into the freeze cycle for 6
minutes before a harvest cycle can be initiated.
Freeze lock is bypassed after moving the toggle
switch from OFF to ICE position for the first cycle
only.
• The maximum freeze time is 60 minutes at which
time the control board automatically initiates a
harvest sequence (steps 5 & 6).
• The maximum harvest time is 3.5 minutes at which
time the control board automatically initiates a freeze
sequence (steps 3 & 4).
WARM WATER RINSE CYCLE
Closing the back of the evaporator allows ice to build up
on the rear of the evaporator and the plastic evaporator
frame parts. After 200 freeze/harvest cycles have been
complete the control board will initiate a warm water
rinse.
After the 200th harvest cycle ends:
• The Clean and Harvest LED’s energize to indicate
the ice machine is in a warm water rinse.
• The compressor and harvest valve remain
energized.
• The water pump energizes.
• The water inlet valve energizes until water contacts
the water level probe.
• The compressor and harvest valve warm the water
for 5 minutes, then de-energize.
• The water pump remains energized for an additional
5 minutes (10 minute total on time) then de-
energizes.
NOTE: The warm water rinse cycle can be terminated by
moving the toggle switch to the OFF position, then back to ICE.

Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally, new installations do
not require any adjustment.
To ensure proper operation, always follow the
Operational Checks:
• when starting the ice machine for the first time
• after a prolonged out of service period
• after cleaning and sanitizing
NOTE: Routine adjustments and maintenance
procedures are not covered by the warranty.
WATER LEVEL
The water level sensor is set to maintain the proper
water level above the water pump housing. The water
level is not adjustable. If the water level is incorrect,
check the water level probe for damage (probe bent,
etc.). Clean the water level probe with ice machine
cleaner, rinse thoroughly and re-check operation. Repair
or replace the probe as necessary.
ICE THICKNESS CHECK
The ice thickness probe is factory-set to maintain the ice
bridge thickness at 1/8" (.32 cm).
NOTE: Make sure the water curtain is in place when
performing this check. It prevents water from splashing
out of the water trough.
1. Inspect the bridge connecting the cubes. It should
be about 1/8" (.32 cm) thick.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness, counterclockwise to decrease
bridge thickness. Set at 1/4” gap between ice
machine and evaporator as starting point, then
adjust to achieve a 1/8” bridge thickness.
Ice Thickness Check
3. Make sure the ice thickness probe wire and the
bracket do not restrict movement of the probe.
