*1. For connecting 15 to 50 type indoor units
Have pipe expansion of indoor unit connecting port by cutting the piping at the
cutting point which depends on the indoor unit capacity.
Note:
Remove burr after cutting the piping to prevent entering the piping.
Check that there is no crack at the pipe expansion part.
*2. To connect a unit with a capacity of higher than 81.
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 80 (Less than 250 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.
