Outside 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 Outside unit multi connection piping
kit. (BHFP22P100U).
(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 supplyed).
How to select the REFNET joint
Piping between outside unit(*2) and refrigerant branch kit (partA)
How to select the REFNET header
When using REFNET joint at the first branch counted from the outside unit side,
choose from the following table in accordance with the outside unit capacity type.
(Example :REFNET jointA)
Choose from the following table in accordance with the outside units system
capacity type.
Piping between outside unit multi connection piping kit and outside unit (part B)
Choose from the following table in accordance with the capacity type
of the outside unit connected.
Choose form the following table in accordance with the total capacity index of all
the indoor units conncted below the REFNET header.
How to select the outside unit multi connection piping kit
(This is required when the system is multi outside unit system.)
Choose from the following table in accordance with the number of outside units.
Choose the REFNET joints other than the first branch from the following table in a accordance
with the total capacity index of all the indoor units connected below the REFNET joint.
