Select pipe size according to outdoor system.
Between two immediately adjacent refrigerant branch kits
and BS unit
●
Select the proper pipe size based on the total capacity index
(Refer to chapter “Combination”) of indoor units connected
downstream, using the following table.
● Select connection pipe size according to the outdoor unit (table
on the bottom left). Do not select a larger pipe size.
Between BS unit and indoor unit
●
Pipe size for direct connection to indoor unit must be the same
as the connection size of indoor unit.

How to select the refnet header
● Select the proper branch kit model based on the total
capacity index (Refer to chapter “CombinationQ”) of indoor
units installed after the header using the following table.
● Branching is impossible between refnet
header and indoor unit.
●
For systems with a total capacity of 640
and over, connect a refnet joint branch.
●
In case of 2 pipes, please select
KHRP26K-H series.

Pipe size selection
Pipe size = outer diameter x minimum wall thickness
(Unit; mm).
Use the included reducing joint which matches the pipe size.
Additional refrigerant to be charged
Calculation of additional refrigerant to be charged R (kg) is in
function of the total length of liquid Iines L

How to select the refnet joint
● When using refnet joints at the first branch counted from the outdoor unit side.
If the system capacity is < 500, use KHRP KHRP26K40TP(Pipe size reducer).
If the system capacity is 500, use KHRP KHRP25K75TP (Pipe size reducer).
●
For refnet joints other than the first branch,
select the proper branch kit model based
on the total capacity index (Refer to chapter
“Combination”) of the indoor units installed
after the first branch using the following
table:
● In case of 2 pipes, please select
KHRP26K-T series
