ICVD TRANSFORMER WIRING

ICVD transformers leave the factory wired for a 240V supply voltage. When connecting to a 208V supply voltage, the transformer must be rewired to maintain a 24V secondary voltage. Failure to correctly wire the transformer can result in premature transformer failure. Refer to wiring diagrams for wiring details.

ICVD INTERCONNECTING WIRING

Important

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 nonoperational machine.

Wire Specifications: 18 AWG 5 Conductor, Single Strand, Plenum Rated, UL rated to 300 volts.
