4.3.5.4 For multi-module system, select appropriate branch ("M1, M2") connected to outdoor module as
per the pipe size of basic outdoor module.
Pipe between module and outdoor branch "M1, M2":
Basic module

Selection of branch "Y1" of outdoor modules:
Module's capacity (C) (Btu/h)
4.3.5.5 Branch selection of the indoor unit side ("A1, A2, A3")
Manifold at indoor unit side can be selected as per total capacity of downstream indoor unit(s).
