*1. Use separately sold parts if the pipe diameter is not appropriate.
*2. If the length of high-pressure pipe A exceeds 65 m (213 ft), use the
ø28.58 (ø1-1/8) pipes for all pipes after 65 m (213 ft).

H Up to three units for 1 branch hole; total capacity: below 54 (but same in cooling/
heating mode)
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
piping following the procedures below.
*1. For connecting 06 to 18 type indoor units
Refer to Fig. 5.2.1.
Note:
Use only the flare nuts supplied with the BC controller.
*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.

*1. The maximum total capacity of indoor units that can be connected to each Sub
BC controller is 126.
*2. Use separately sold parts if the pipe diameter is not appropriate.
*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.
