comply with all applicable local and national codes.
• If using the LG Controller / Extension cable and the length needs to be further extended, the LG Extension Kit (sold separately) must be

• Indoor unit controller connections depend on type of indoor unit being installed. Some indoor units use terminal block connections; other
indoor units use Molex connections. See diagrams below for the two options. Refer to the wiring diagram schematic found in the indoor unit
itself, or to the indoor unit wiring diagrams in the Engineering Manuals for more information.
•
NEVER splice, cut, or extend cable length with field provided cable. Always include enough cable to cover distance between the indoor
unit and the remote controller.
• Set the indoor unit operating parameters using DIP switches, or by setting up the remote controller. Refer to the indoor unit installation
manuals for more details.
Cable connected to Zone Controller is the factory default connection.
