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
All power wiring / communication cables to be four-conductor, stranded, shielded, and must comply with applicable local and national codes.
4
Piping lengths are equivalent.
Due to our policy of continuous product innovation, some specications may change without notication.
