*1. For connecting 20 to 50 type indoor units
Connect indoor units using the reducers (specials) supplied with BC controllers.
*2. To connect a unit with a capacity of higher than 141.
After combining two branches using an optionally available piping kit (CMY-R160-
J), connect indoor units.
*3. Connection of plural indoor units with one connection (or joint pipe)
• Total capacity of connectable indoor units: Less than 140 (Less than 250 with
joint pipe)
• Number of connectable indoor units: Maximum 3 Sets
• Branch pipe: Use the branch pipe for CITYMULTI Y Series (CMY-Y102S-G)
• Selection of refrigerant piping
Select the size according to the total capacity of indoor units to be installed
downstream.
