4.2 Preparing refrigerant piping
4.2.1 Refrigerant piping requirements
NOTICE
The piping and other pressure-containing parts shall be
suitable for refrigerant. Use phosphoric acid deoxidised
seamless copper for refrigerant.
▪ Foreign materials inside pipes (including oils for fabrication) must
be ≤30mg/10m.
▪ Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.
Pipe Ø Temper grade of piping material
≤15.9mm O (annealed)
≥19.1mm 1/2H (half hard)
▪ All piping lengths and distances have been taken into
consideration (see About the piping length in the installer
reference guide).
▪ The pipe thickness of the refrigerant piping shall comply with the
applicable legislation. The minimal pipe thickness for R410A
piping must be in accordance with the table below.
Pipe Ø Minimal thickness t
6.4mm/9.5mm/12.7mm 0.80mm
15.9mm 0.99mm
19.1mm/22.2mm 0.80mm
28.6mm 0.99mm
34.9mm 1.21mm
41.3mm 1.43mm

If the hydro module connections do not match the diameter of the
specified piping requirements, the piping diameter requirements
must be met using reducers/expanders (field supply) on the hydro
module connections.
If the indoor unit connections do not match the diameter of the
specified piping requirements, the piping diameter requirements
must be met using reducers/expanders (field supply) on the indoor
unit connections.
Other diameters (mm sizes) can also be used if the required pipe
sizes (inch sizes) are not available, taking the following into account:
▪ select the pipe size nearest to the required size,
▪ use the suitable adapters for the change-over from inch to mm
pipes (field supply).
4.2.3 About the piping length
Maximum piping length and height difference
Maximum allowable piping length 30m
Height difference between indoor and outdoor unit <10m
Height difference between outdoor unit 1 and outdoor
unit 2 (if applicable)
0m
4.3 Preparing water piping
4.3.1 To check the water volume and expansion
vessel pre-pressure
The unit has an expansion vessel of 12 litre with a default pre-
pressure of 1bar.
See the installer and user reference guide for more information.
