R410A Refrigerant System
Y-type Manifold
(6). Fitting pipe between manifolds
Pipe size (between two manifolds at indoor unit side) is based on the total capacity of upstream
indoor unit(s).
Total Rated Capacity X(kW) of
Downstream Indoor Units
(7). Fitting pipe between indoor unit and manifold
Manifold should be matched with fitting pipe of indoor unit.
