1-3 Combination
• This Branch Selector unit is only for systems for models REYQ-T and PC series.
It cannot be connected to systems for models REYQ-M, P, PA and PB series.
•
For series of applicable indoor units, refer to the catalog or other literature.
• Select the Branch Selector unit to fit the total capacity (sum of unit’s capacity) of the indoor units
to be connected downstream, refer to the Table 1. About indoor unit’s capacity, refer to the Table 2.

The total capacity and number of indoor units connectable to each branch connector are up to
54 and 5, respectively. When the total capacity of indoor units to be connected downstream is
larger than 54 (MAX. 96), use a junction pipe kit (KHRP26A250T, sold separately) to join two
connections downstream from the Branch Selector unit.
