Up to three units for 1 branch hole; total capacity: below 54 (but same in cooling/heat-

The size of BC controller’s branch piping is for 24 to 54 type indoor units.
Therefore, if you want to connect indoor units other than the above, connect pip-
ing following the procedures below.
*1. For connecting 06 to 18 type indoor units
Refer to Fig. 5.2.1.
Note:
8VHRQO\WKHÀDUHQXWVVXSSOLHGZLWKWKH%&FRQWUROOHU
*2. To connect a unit with a capacity of higher than 54.
After combining two branches using an optionally available piping kit
(CMY-R160-J1), connect indoor units.
*3. Connection of plural indoor units with one connection (or joint pipe)
‡
Total capacity of connectable indoor units: Less than 54 (Less than 96 with
joint pipe)
‡
Number of connectable indoor units: Maximum 3 Sets
‡
Twinning pipe: Use the twinning pipe for CITY MULTI Y Series (CMY-
Y102S-G2)
‡
Selection of refrigerant piping
Select the size according to the total capacity of indoor units to be installed
downstream.
