• Use a conduit for the communications / connection (power) cable from the outdoor unit to the indoor units and branch distribution unit(s).

Electrical interference my cause product malfunction.

• The communications / connection (power) cable from the outdoor unit to the indoor units / branch distribution unit(s) must be separated and

isolated from power wiring to the outdoor unit, computers, radio and television broadcasting facilities, as well as medical imaging equip-

ment. Electrical interference my cause product malfunction.

• Multi F with LGRED Systems:

• All communication / connection (power) cable from the outdoor unit to the indoor unit

must be a minimum of 18 AWG, four (4) conductor, stranded, shielded or unshielded

(if shielded, it must be grounded to the chassis of the outdoor unit only), and must

comply with applicable local and national codes.

• Multi F MAX with LGRED Systems:

• All communication / connection (power) cable from the outdoor unit to the branch dis-

tribution unit(s) must be a minimum of 16 AWG, four (4) conductor, stranded, shielded

or unshielded (if shielded, it must be grounded to the chassis of the outdoor unit only),

and must comply with applicable local and national codes.

• All communication / connection (power) cable from the branch distribution unit(s) to

the indoor units must be a minimum of 18 AWG, four (4) conductor, stranded, shielded

or unshielded (if shielded, it must be grounded to the chassis of the outdoor unit only),
