13 Piping installation
13.1 Preparing refrigerant piping
13.1.1 Refrigerant piping requirements
CAUTION
Piping MUST be installed according to instructions given in
"13Piping installation"[4 18]. Only mechanical joints (e.g.
braze+flare connections) that are compliant with the latest
version of ISO14903 can be used.
NOTICE
The piping and other pressure-containing parts shall be
suitable for refrigerant. Use phosphoric acid deoxidised
seamless copper for refrigerant piping.
▪ Foreign materials inside pipes (including oils for fabrication) must
be ≤30mg/10m.
Refrigerant piping diameter
For piping connections of the indoor unit use the following piping
diameters:
Class Pipe outer diameter (mm)
Liquid pipe Gas pipe
15~32 Ø6.4 Ø9.5
40+50 Ø6.4 Ø12.7
Refrigerant piping material
▪ Piping material: phosphoric acid deoxidised seamless copper
▪ Flare connections: Only use annealed material.
▪ Piping temper grade and thickness:

Depending on the applicable legislation and the maximum
working pressure of the unit (see "PS High" on the unit name
plate), larger piping thickness might be required.
13.1.2 Refrigerant piping insulation
▪ Use polyethylene foam as insulation material:
▪ with a heat transfer rate between 0.041 and 0.052W/mK (0.035
and 0.045kcal/mh°C)
▪ with a heat resistance of at least 120°C
▪ Insulation thickness:
