Refrigerant lines
6.1.2 Refrigerant pipes passing through open air
1 Appropriately sealed wall conduit (particularly where
there is a risk of flooding)
2 Appropriate sealing of the refrigerant lines as they
pass through the wall conduit
3 Refrigerant lines in open air (enclosed in thermal in-
sulation with UV protection)
4 Reinforced strip foundation
5 Drainage pipe (frostproof)
6 Foundation
Note
All solder joints on the refrigerant copper pipework
must be accessible all year round for mainte-
nance purposes (according to Regulation (EU) No
517/2014).
»
Run the refrigerant pipes between the indoor and out-
door units.
»
Allow some surplus length in the refrigerant pipes
between the connections at the indoor and outdoor
units.
»
Use suitable sound-insulating pipe fixings to secure
the refrigerant pipes.
»
Do not install the pipe fixings in the vicinity of bending
radii.
»
Insulate the refrigerant lines with suitable insulating
material where they pass through open air between
the indoor and outdoor units, to prevent the formation
of condensation and corrosion. When passing above
ground outside, the insulating material must also have
UV protection.
Note
Where the refrigerant pipes run horizontally through
open air, use suitable supports. Take steps to pre-
vent above-ground refrigerant pipes from being
walked or driven on.
6.1.3 Underground refrigerant pipes
1 Appropriately sealed wall conduit
2 Appropriate sealing of the refrigerant lines as they
pass through the pipe liner
3 Insulation
4 Gravel
5 Reinforced foundation
6 Appropriate sealing at the end of the pipe liner (be-
tween refrigerant lines and pipe liner)
7 Drainage pipe (frostproof)
8 Pipe liner (with min. 2% fall to outside)
9 Drainage
10 Foundation
Note
All solder joints on the refrigerant copper pipework
must be accessible all year round for mainte-
nance purposes (according to Regulation (EU) No
517/2014).
Note
If the pipe liner is laid empty, inserting the re-
frigerant lines afterwards will be difficult, if not
impossible, depending on the configuration of the
connection lines.
»
When laying refrigerant lines in the ground,
schedule the work so that the pipe liner can
be laid together with the pre-inserted refrig-
erant lines in the trench between the outdoor
and indoor units.
