13 Piping installation
13.1 Preparing refrigerant piping
13.1.1 Refrigerant piping requirements
CAUTION
Piping MUST be installed according to instructions given in
"13Piping installation"[419]. 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 ≤30mg/10m.
Refrigerant piping diameter
For piping connections of the indoor unit, use the following piping
diameters:
Class Pipe outer diameter (mm)
Liquid pipe Gas pipe
32 Ø6.4 Ø9.5
50+63 Ø6.4 Ø12.7
100 Ø9.5 Ø15.9
Refrigerant piping material
Piping material: phosphoric acid deoxidised seamless copper
Flare connections: Only use annealed material.

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 0.052W/mK (0.035
and 0.045kcal/mh°C)
with a heat resistance of at least 120°C

If the temperature is higher than 30°C and the humidity is higher
than RH80%, the thickness of the insulation materials should be at
least 20 mm to prevent condensation on the surface of the
insulation.
13.2 Connecting the refrigerant piping
DANGER: RISK OF BURNING/SCALDING
13.2.1 To connect the refrigerant piping to the
indoor unit
CAUTION
Install the refrigerant piping or components in a position
where they are unlikely to be exposed to any substance
which may corrode components containing refrigerant,
unless the components are constructed of materials that
are inherently resistant to corrosion or are suitably
protected against corrosion.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
Refrigerant piping can be connected from following directions:
a
b
c
a Rear right piping
b Right piping
c Upward piping
Rear right piping
1 Remove the rear piping pipe port cover and cut out the holes for
piping. When cutting out the holes, make sure to avoid the knob
part of the cover.
