Outdoor unit multi connection piping kit and Refrigerant branch kit selection Pipe size selection
•
Refrigerant branch kits can only be used with R410A.
•
When multi outdoor system are installed, be sure to use the
special separately sold Outdoor unit multi connection piping kit. (BHFP26P90U). (For how to select the proper kit, follow the table at right.)
•
Never use BHFP26M90U, BHFP22M90U for M type of this
series or T joint (field supplied).
How to select the REFNET joint Piping between outdoor unit (*2 and refrigerant branch kit (part A)
