Branch piping set (option)
(1) A riser pipe must be part of the main.
A branching pipe set should be installed horizontally at point as close to an indoor unit as possible.
(2) Reduce refrigerant amount by 1.0kg from the factory charge when refrigerant piping is shorter than 3m.

becomes
the
longest

Keep the pipe length difference
between L1 and (La + L2)
or (La + L3) within 10m.
