General Information
Ice Deflector
Top Air Discharge Kit
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.
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.
Bin Level Accessory Kit
LuminIce® II
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.
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.
Bin Installation
• The control board can be set to automatically display a
reminder after 12 months.
• All ice machines installed on a bin require an ice
deflector.
• LuminIce® bulbs require replacement on a yearly basis.
• A remote light is available for reminder indication.
• Manitowoc bins have a deflector installed and require
no modifications when used with a forward-facing
evaporator.
NOTE: LuminIce® and LuminIce® II bulbs are not
interchangeable; verify your model before ordering a
replacement bulb.
• Ice machines with multiple evaporators require a
deflector kit.
Cleanup Procedure for Accidental Bulb Breakage
• 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 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.
The latest EPA procedures can be viewed on their website at
www.epa.gov/cfl/cflcleanup.html.
• 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.

Installation
Section 2
Electrical Requirements
Fuse/Circuit Breaker
All electrical work, including wire routing and grounding,
must conform to local, state and national electrical codes.
The following precautions must be observed:
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.
• 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).
nWarning
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).
nWarning
The ice machine must be grounded in accordance with
national and local electrical codes.
12
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.
Importan
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.

Installation
ICVD Interconnecting Wiring
ICVD Transformer Wiring
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.
ICVD condensing units leave the factory with the L2
voltage leads for the transformer disconnected. Failure to
connect the transformer leads will result in a non-operable
condensing unit. Failure to correctly wire the transformer will
result in premature transformer failure.
1. Measure voltage with a voltmeter
2. Wire transformer to match voltage range
3. Cap unused lead to prevent shorting to ground.
Connections on an RDI condensing unit are identical to the
ICVD connections.

Drain Connections
Auxiliary Base Drain Installation
Follow these guidelines when installing drain lines to prevent
drain water from flowing back into the ice machine and
storage bin:
Two types of auxiliary drain are located in the ice machine
base to remove moisture in high humidity areas: With or
without a drain socket.
• Drain lines must have a of run 2.5 cm per meter (1.5 inch
drop per 5 feet) and must not create traps.
ICE MACHINES WITH AN AUXILIARY DRAIN SOCKET
1. Remove membrane in socket with a dowel or
screwdriver and proceed to step 3.
• 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.
ICE MACHINES WITHOUT AN AUXILIARY DRAIN SOCKET
1. View the back of the ice machine base on the
compressor side, and locate the dimple.
2. Drill a 16 mm (5/8") hole using the dimple as a guide.
NOTE: Do not use a drill larger than 16 mm (5/8") or
irreparable damage will occur.
3. Route tubing to an open site drain:
• Use 1/2 inch CPVC tubing.
• Provide support for 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.

CALCULATING REMOTE CONDENSER & REMOTE CONDENSING UNIT INSTALLATION DISTANCES
Line Set Length
1. Insert the measured rise into the formula below.
Multiply by 1.7 to get the calculated rise.
The maximum tubing length is 30 meters (100 feet).
2. Insert the measured drop into the formula below.
Multiply by 6.6 to get the calculated drop.
Line Set Rise/Drop
The maximum rise is 10.7 meters (35 feet).
3. Insert the measured horizontal distance into the
formula below. No calculation is necessary.
The maximum drop is 4.5 meters (15 feet).
,Caution
4. Add together the calculated rise, calculated drop, and
horizontal distance to get the total calculated distance.
If this total exceeds 45 meters (150 feet), move the
condenser/condensing unit to a new location and
perform the calculations again.
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 45 meters (150 feet).
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.

Installation
QuietQube Models Only
Step 3 Connect the Line Set.
Remote Condensers Only
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,

Operation
Ice Making Sequence of Operation
Safety Limits
Ice machines and storage bins produce and store ice for
human consumption and product cooling.
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.
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.
• 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.
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.

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").
