1
At least one branch distribution Unit is required for system operation; a maximum of two can be installed per outdoor unit with use of Y-branch accessory (PMBL5620) To connect only
one (1) indoor unit to a branch distribution unit, the system must include another branch distribution unit with at least one (1) connected indoor unit.
2
Branch distribution Unit can accommodate from one (1) indoor unit up to four (4) indoor units depending on the ports available on the branch distribution Unit.
3
Communication / power (connection) cable must be a minimum of 14 AWG, 4-conductor from the outdoor unit to the branch distribution unit (Multi F MAX systems only), and 14 AWG,
4-conductor from the branch distribution unit to the indoor unit, 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.
4
Piping lengths are equivalent.
