ICVD Interconnecting 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.
Connections on an RDI condensing unit are identical to the
ICVD connections.

ICVD Transformer Wiring
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.

Remote Condenser Wiring
Interconnecting line voltage wiring is used to energize and
de-energize the condenser fan motor.
The remote condenser voltage matches the ice machine
head section voltage.
