An ice deflector is required when the ice machine is
installed on a bin. An ice deflector is not required when the
ice machine is installed on a dispenser.
Bin Level Accessory Kit
The bin level accessory connects to the circuit board and
allows bin level adjustment of Indigo ice machines on B
model bins. Installation instructions are included with the
accessory. A bin level sensor is required to set a lower level
of ice in the bin.
Bin Installation
• All ice machines installed on a bin require an ice
deflector.
• Manitowoc bins have a deflector installed and require
no modifications when used with a forward-facing
evaporator.
• Ice machines with multiple evaporators require a
deflector kit.
• Align sides and back of ice machine with sides and back
of bin when placing ice machine on bin.
Control Panel Bezel
The ice machine ships with two bezels:
• The standard bezel allows the display screen to be
viewed and the menu, arrows and check mark buttons
can be accessed.
• The key guard bezel allows the display screen to be
viewed and covers all buttons to prevent unauthorized
settings from being entered. The ice machine door must
be opened to access the control panel.
To change the bezel, open the ice machine door, remove
the two screws securing the bezel and slide the bezel to the
right while lifting forward.
An optional cover that completely hides the display is a
sales kit, and is available through your local distributor or
service company.
Top Air Discharge Kit
The top air discharge kit can be used on select ice machine
models. This kit directs warm exhaust air upward rather
than out the side panels.
LuminIce® II
The LuminIce® growth inhibitor recirculates the air in the ice
machine foodzone over a UV bulb. This process will inhibit
the growth of common micro-organisms on all exposed
foodzone surfaces.
• LuminIce® bulbs require replacement on a yearly basis.
• The control board can be set to automatically display a
reminder after 12 months.
• A remote light is available for reminder indication.
NOTE: LuminIce® and LuminIce® II bulbs are not
interchangeable; verify your model before ordering a
replacement bulb.
Cleanup Procedure for Accidental Bulb Breakage
The cleanup procedure is identical to the procedure used
to clean up compact fluorescent (CFL) or fluorescent tube
lights. These lights contain a small amount of mercury
sealed within a glass tube. Breaking these types of lights
will release mercury and mercury vapor. The broken bulb
can continue to release mercury vapor until it is cleaned up
and removed.

Part Number: 000013325 Rev 01 4/16 11
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).
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).
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 (3/16") 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.
Important
3-Phase Scroll Compressors Only - Verify the direction
of rotation is correct on the 3-phase scroll compressor.
The ice machine will have high suction pressure, low
discharge pressure and will be noticeably loud. Reverse
any two incoming power leads to reverse rotation.

pressure and will be noticeably loud. Reverse two incoming power leads to reverse rotation.
Indigo QuietQube ice machines require interconnecting
low voltage wiring (included with Manitowoc line sets) to
energize the contactor coil and verify the LPCO & HPCO
are closed. This circuit also initiates a time delay whenever
the LPCO or HPCO open. Failure to properly wire the ICVD
condensing unit or ice machine head section will result in
a non-operational machine. Refer to the Indigo Technicians
Handbook for normal operation and diagnostics for the
HPCO & LPCO controls.
Connections on an RDI condensing unit are identical to the
ICVD connections.

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. 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 145 grams (5 oz) of
vapor refrigerant charge in each line.

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 3 mm (1/8").
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 3 mm (1/8") 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 7 mm (9/32") gap between ice
thickness probe and evaporator as starting point, then
adjust to achieve a 3 mm (1/8") bridge thickness.
NOTE: Turning the adjustment one-third of a turn will
change the ice thickness about 1.5 mm (1/16").

Section 3 Operation
Ice Making Sequence of Operation
Ice machines and storage bins produce and store ice for
human consumption and product cooling.
NOTE: 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.
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 60 minutes, at which time
the control board automatically initiates a harvest
sequence.
• The maximum harvest time is 3.5 minutes. The control
board automatically initiates a freeze sequence when
these times are exceeded.
Safety Limits
Safety limits are stored and indicated by the control board
after three cycles. The number of cycles required to stop the
ice machine varies for each safety limit.
• Safety Limit 1 - If the freeze time reaches 60 minutes,
the control board automatically initiates a harvest cycle.
If 6 consecutive 60-minute freeze cycles occur, the ice
machine stops.
• Safety Limit 2 - If the harvest time reaches 3.5 minutes,
the control board automatically returns the ice machine
to the freeze cycle. If 500 consecutive 3.5 minute harvest
cycles occur, the ice machine stops.
A safety limit is indicated by a flashing control board light
labeled SL1 or SL2. Refer to Section 5 if you receive a safety
limit indication.
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 LCD 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.

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 should be
about 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 at 9/32" (7 mm) 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 1.5 mm (1/16").

Cleaning the Condenser
General
Warning
Disconnect electric power to the ice machine 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.
Warning
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.
Step 4 Close and secure the front door. The ice machine
will automatically start ice-making after the clean cycle is
complete (approximately 24 minutes).
