The size of BC controller’s branch piping is for 63 to 140 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

Connect indoor units using the reducers supplied with BC controllers.

Note:

*2.  To connect a unit with a capacity of higher than 31.

After combining two branches using an optionally available piping kit 
(CMY-R160-J1), connect indoor units.

Note:
Be sure to use non-oxidative brazing.

5.3.  Refrigerant piping work

After connecting the refrigerant pipes of all indoor and outdoor units with the out-
door units’ stop valves remained fully closed, evacuate vacuum from the outdoor 
units’ stop valve service ports.
After completing the above, open the outdoor units’ stop valves. This connects 
the refrigerant circuit (between outdoor and BC controller) completely.
How to handle stop valves is described on each outdoor unit.

‡

Use two wrenches for pipe connection.

‡

After pipe connection, be sure to check that there is no gas leakage, 
using a leak detector or soap-and-water solution.

‡

Before brazing the refrigerant piping,

 always wrap the piping on the main 

body, and the thermal insulation piping, with damp cloths to prevent 
heat shrinkage and burning the thermal insulation tubing. 

Take care to
