Pipe size for direct connection to indoor unit must be the same as
the connection size of the indoor unit (in case indoor unit is VRVDX
indoor).

If a size-up of the piping is required, refer to the table below:
Size up – outer diameter [mm]
HP class Gas piping Liquid piping
5 — 9.5 → 12.7
8~10 19.1 → 22.2
12~14 22.2 → 28.6 12.7 → 15.9

▪ In case the required pipe sizes (inch sizes) are not available, it is
also allowed to use other diameters (mm sizes), taken the
following into account:
▪ Select the pipe size nearest to the required size.
▪ Use the suitable adapters for the changeover from inch tomm
pipes (field supply).
▪ The additional refrigerant calculation has to be adjusted as
mentioned in "16.3 To determine the additional refrigerant
amount"[436].
▪ Applicable pipe size up is decided upon field piping rules
determined by the installation needs. See technical data and
installer user reference guide for more details about the required
pipe size up for your installation.
15.1.4 To select refrigerant branch kits
Refrigerant refnets
For piping example, refer to "15.1.3To select the piping size"[428].
▪ When using refnet joints at the first branch counted from the
outdoor unit side, choose from the following table in accordance
with the capacity of the outdoor unit.
HP class Refrigerant branch kit
8~13 KHRQ22M29T9 (inch)
KHRQM22M29T (mm)
14~20 KHRA22M65T (inch)
KHRAM22M65T (mm)
▪ For refnet joints other than the first branch, select the proper
branch kit model based on the total capacity index of all indoor
units connected after the refrigerant branch.

▪ Concerning refnet headers, choose from the following table in
accordance with the total capacity of all the indoor units connected
below the refnet header.

INFORMATION
Maximum 8 branches can be connected to a header.
▪ How to choose an outdoor multi connection piping kit. Choose
from the following table, in accordance with the number of outdoor
units.

For multi combination of models RXYA8~12 + RYMA5 there is an
additional equalising pipe (in addition to the conventional gas and
liquid piping).
The equalising pipe connections for the different modules are
mentioned in below table.
