16 Part Number: 000014141 Rev 03 2/18
Installation Section 2
Electrical Requirements
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
(dedicated circuit) must be provided
for each ice machine head section,
condenser or condensing unit.
• A qualified electrician must determine
proper wire size dependent upon
location, materials used and length of
run (minimum circuit ampacity can be
used to help select the wire size).
n
Warning
All wiring must conform to local, state and
national codes.
Voltage
The maximum allowable voltage variation
is +10% / -5% of the rated voltage at ice
machine start-up (when the electrical load
is highest).
n
Warning
The ice machine must be grounded
in accordance with national and local
electrical codes.
Fuse/Circuit Breaker
A separate electrical disconnect, which
disconnects all poles and has 3 mm (1/8")
contact separation, must be provided
for fixed wiring. Circuit breakers must be
H.A.C.R. rated in USA.
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) also depends on
location, materials used, length of run, etc.,
so it must be determined by a qualified
electrician.
Ground Fault Circuit Interrupter
We do not recommend the use of a GFCI/
GFI circuit protection with our equipment.
If a GFCI/GFI is required by code, use a
GFCI/GFI breaker rather than an outlet,
which is more prone to intermittent
nuisance trips than panel circuit breakers.

Section 2 Installation
Air Gap
A greater than 1-inch air gap is built into
the ice machine for back-flow prevention.
This air gap exceeds NSF 12 requirements
for back-flow prevention.
Cooling Tower Applications
(Water-Cooled Models)
A water cooling tower installation does not
require modification of the ice machine.
• Water pressure at the condenser cannot
exceed 150 psig (1034 kPa). A special
order unit is available that allows water
pressure up to 350 psig (2413 kPa).
• Water entering the condenser must not
exceed 90°F (32°C).
• Water flow through the condenser
must not exceed 5 gallons (19 liters) per
minute.
• Allow for a pressure drop of 7 psi
(50 kPa) between the condenser water
inlet and the outlet of the ice machine.
• Water exiting the condenser must not
exceed 110°F (43°C).
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 of run 1.5 inch
drop per 5 feet (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 ice machine drain to the
atmosphere.
• Drain termination must have an air gap
that meets local code.
Auxiliary Base Drain Installation
An auxiliary drain is located in the ice
machine base to remove moisture in high
humidity areas.
1. View the back of the ice machine base
on the compressor side and locate and
remove the cap plug.
2. Route tubing to an open site drain:
• Use 1/2 inch CPVC tubing.
• Apply a bead of silicone around the
exterior of the ice machine tubing
and insert into ice machine base. The
silicone will secure the tubing and
provide a watertight seal.
• Provide support for tubing.

Warning
Potential Personal Injury Situation
The ice machine head section contains
the refrigerant charge. Installation and
brazing of the line sets must be performed
by a properly trained and EPA certified
refrigeration technician aware of the
dangers of dealing with refrigerant charged
equipment.
CALCULATING INSTALLATION DISTANCES
Line Set Length
The maximum tubing length is 100 feet (30
meters).
Line Set Rise/Drop
The maximum rise is 35 feet (10.7 meters).
The maximum drop is 15 feet (4.5 meters).
Notice
If a line set has a rise followed by a drop,
another rise cannot be made. Likewise,
if a line set has a drop followed by a rise,
another drop cannot be made.
Calculated Line Set Distance
The maximum calculated distance is 150
feet (45 meters).
Line set rises, drops, horizontal runs (or
combinations of these) in excess of the
stated maximums will exceed compressor
start-up and design limits. This will cause
poor oil return to the compressor. Make the
following calculations to make sure the line
set layout is within specifications.
1. Insert the measured rise into the
formula below. Multiply by 1.7 to get
the calculated rise.
2. Insert the measured drop into the
formula below. Multiply by 6.6 to get
the calculated drop.
3. Insert the measured horizontal
distance into the formula below. No
calculation is necessary.
24 Part Number: 000014141 Rev 03 2/18
Installation Section 2
4. Add together the calculated rise,
calculated drop, and horizontal
distance to get the total calculated
distance. If this total exceeds 150 feet
(45 meters), move the condenser/
condensing unit to a new location and
perform the calculations again.

• Maximum line set exposed on rooftop is
25% of total line set length.
• A qualified person must perform all roof
penetrations.
Step 3 Connect the Line Set.
In most cases, by routing the line set
properly, shortening will not be necessary.
When shortening or lengthening is
required, do so before connecting the
line set to the ice machine or the remote
condenser. This prevents the loss of
refrigerant in the ice machine or condenser.
The quick connect fittings on the line sets
are equipped with access valves. Use these
valves to recover any vapor charge from the
line set.
Part Number: 000014141 Rev 03 2/18 25
Section 2 Installation
When lengthening or shortening lines,
follow good refrigeration practices, purge
with nitrogen and insulate all tubing. Do
not change the tube sizes. Evacuate the
lines and place about 5 oz (145 grams) of
vapor refrigerant charge in each line.
1. Remove the dust caps from the line
set, condenser and ice machine.
2. Apply refrigeration oil to the threads
on the quick-disconnect couplers
before connecting them to the
condenser.
3. Carefully thread the female fitting to
the condenser or ice machine by hand,
then tighten the couplings with a
wrench until they bottom out.
4. Turn an additional quarter turn to
ensure proper brass-to-brass seating.

Remote Ice Machine Usage with Non-
Manitowoc Multi-Circuit Condensers
Warranty
The sixty (60) month compressor warranty,
including thirty six (36) month labor
replacement warranty, shall not apply when
the remote ice machine is not installed
within the remote specifications. The
foregoing warranty shall not apply to any
ice machine installed and/or maintained
inconsistent with the technical instructions
provided by Manitowoc Ice. Performance
may vary from Sales specifications. ARI
certified standard ratings only apply when
used with a Manitowoc remote condenser.
If the design of the condenser meets the
specifications, Manitowoc’s only approval
is for full warranty coverage to be extended
to the Manitowoc manufactured part of
the system. Since Manitowoc does not
test the condenser in conjunction with the
ice machine, Manitowoc will not endorse,
recommend, or approve the condenser, and
will not be responsible for its performance
or reliability.
Important
Manitowoc warrants only complete
new and unused remote packages.
Guaranteeing the integrity of a new ice
machine under the terms of our warranty
prohibits the use of pre-existing (used)
tubing or condensers.

Design & Burst Pressure
Design Pressure 600 psig - 4137 kPa
Burst Pressure 2500 psig - 17237 kPa
Head Pressure Control Valve
Do not use a fan cycling control to try to
maintain discharge pressure. Compressor
failure will result. Any remote condenser
connected to a Manitowoc Ice Machine
must have the OEM head pressure control
valve installed. Manitowoc will not accept
substitute “off the shelf” head pressure
control valves.
Fan Motor
The condenser fan must be on during the
complete ice machine freeze cycle (do
not cycle on fan cycle control). The ice
maker has a condenser fan motor circuit
for use with a Manitowoc condenser. It is
recommended that this circuit be used to
control the condenser fan(s) on the multi-
circuit condenser to assure it is on at the
proper time. Do not exceed the rated amps
for the fan motor circuit listed on the ice
machine’s serial tag.
Internal Condenser Volume
The multi-circuit condenser internal
volume must not be less than or exceed
that used by Manitowoc. Do not exceed
internal volume and try to add charge to
compensate, as compressor failure will
result.

Section 3 Operation
Ice Making Sequence of Operation
The power button must be depressed and
the water curtain/ice dampers must be
in place on the evaporator before the ice
machine will start.
Water Purge Cycle
The ice machine purges any remaining
water from the water trough down the
drain.
Prechill Cycle
The refrigeration system cools the
evaporator before the water pump is
energized.
Freeze Cycle
Water flows across the evaporator and the
refrigeration system chills the evaporator.
Ice builds on the evaporator and the freeze
cycle continues until the ice thickness
probe senses a sheet of ice has formed.
The ice thickness probe signals the control
board to start a harvest.
Harvest Cycle
Any remaining water is purged down
the drain as refrigerant gas warms the
evaporator. When the evaporator warms,
the sheet of cubes slides off the evaporator
and into the storage bin. If all cubes fall
clear of the water curtain (or ice damper)
the ice machine starts another freeze cycle.
Off Cycle
If the water curtain or ice damper are held
open by ice cubes the ice machine shuts
off. When the water curtain or ice damper
closes, the ice machine starts a new cycle at
the water purge.
Control Board Timers
The control board has the following non-
adjustable timers:
• The ice machine control board will set
its own install date after 100 freeze and
harvest cycles.
• The ice machine is locked into the freeze
cycle for 6 minutes before a harvest cycle
can be initiated.
• The maximum freeze time is 35
minutes at which time the control
board automatically initiates a harvest
sequence.
• The maximum harvest time is 7 minutes,
the control board will perform a water
thaw cycle and then return the ice
machine to the freeze cycle.
Service Faults
Service Faults are stored and indicated by
the control board after three cycles. The
number of cycles required to stop the ice
machine varies for each Service Fault.
• Long Freeze Cycle - If the freeze time
reaches 35 minutes, the control board
automatically initiates a harvest cycle.
If 6 consecutive 35 minute freeze cycles
occur, the ice machine stops.
• Long Harvest Cycle - If the harvest time
reaches 7 minutes, the control board
automatically returns the ice machine to
the freeze cycle. After 3 consecutive long
harvest cycles the ice machine stops.
Refer to Section 5 if you receive an alert for
Service Fault E01 or E02.
36 Part Number: 000014141 Rev 03 2/18
Operation Section 3
Safe Operation Mode
Allows the ice machine to operate up to
72 hours if the ice thickness probe and/or
water level probe sensors fail.
• When the control board starts the safe
mode, an alert is flashed on the display
to notify the end-user they have a
production problem.
• The control board automatically initiates
and monitors the safe mode. The control
will automatically exit the safe mode if a
normal signal is received from the input.
• After 72 hours, the control board will
enter a standby mode and turn off.
NOTE: The control board needs a five cycle
history to operate safe mode. If five cycles
have never been successfully completed
the ice machine will shut-off.
Water Assist Harvest
When the damper/curtain does not open
within 3.5 minutes in the harvest cycle the
following occurs:
• 3.5 minutes - The water inlet valve
energizes until water touches the high
water level probe.
• 4 minutes - The water pump energizes.
• 6.5 to 7 minutes - The water dump valve
energizes.
Water Thaw Cycle
When the damper/curtain does not open
during the 7 minute harvest cycle the
following water thaw cycle occurs:
• 7 minutes - The compressor, harvest
solenoid valve and dump valve de-
energize.
1. The water pump remains energized
and the water inlet valve energizes
until water touches the high water
level probe.
2. Water is circulated over the
evaporator.
3. Water is circulated, dumped and
refilled to the high water level probe
for approximately 1 hour.
• At the end of the thaw cycle the ice
machine will start another freeze cycle
(approximately 1 - 1.75 hour).

Ice Thickness Check
After a harvest cycle, inspect the ice cubes
in the ice storage bin. The ice thickness
probe is factory-set to maintain the ice
bridge thickness at 1/8" (3 mm).
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 must be approximately
1/8" (3 mm) thick.
2. If adjustment is necessary, turn the
ice thickness probe adjustment screw
clockwise to increase bridge thickness,
counterclockwise to decrease bridge
thickness. Set a 7 mm (9/32") gap
between ice thickness probe and
evaporator as starting point, then
adjust to achieve a 1/8" (3 mm) bridge
thickness.
NOTE: Turning the adjustment one-third of
a turn will change the ice thickness about
1/16" (1.5 mm).

Section 4 Maintenance
Cleaning the Air Filter and Condenser
The washable filter on self-contained ice
machines is designed to catch dust, dirt, lint
and grease. Clean the filter once a month
with mild soap and water.
A dirty condenser restricts airflow, resulting
in excessively high operating temperatures.
This reduces ice production and shortens
component life.

machine at the electric service switch
before cleaning the air filter or the
condenser. The condenser fins are sharp;
Use care when removing or installing the
air filter.
• Clean the condenser at least every six
months.
• 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.

Service Faults
In addition to the standard safety controls,
such as the high pressure cutout, your
Manitowoc ice machine features built-
in service faults which will stop the ice
machine if conditions arise which could
cause a major component failure.
Before calling for service, re-start the ice
machine using the following procedure:
1. Press the power button. The display
reads “Off”. Press the power button
again, and the display reads “Making
Ice”.
A. If a service fault has stopped the
ice machine, it will restart after a
short delay. Proceed to step 2.
B. If the ice machine does not
restart, see “Ice machine does not
operate” on page 47.
2. Allow the ice machine to run to
determine if the condition repeats.
A. If the ice machine stops again, the
condition has repeated. Call for
service.
B. If the ice machine continues to
run, the condition has corrected
itself. Allow the ice machine to
continue running.
