Refrigerant lines
»
Keep the distance between the indoor and outdoor
units to a minimum to prevent heat loss from the re-
frigerant pipes.
»
Select the installation sites for the indoor and outdoor
units so that the maximum permissible line lengths
and height differentials are observed.
»
Avoid routing the lines in the vicinity of rooms that are
sensitive to sound (e.g. bedrooms). The refrigerant in
the lines can generate noise under certain operation-
al conditions.
»
Use the largest possible bending radii to avoid high
pressure losses.
6.1.1 Line lengths
»
Observe the maximum permissible line lengths for
the refrigerant lines.
»
Observe the maximum permissible height differential
between the indoor and outdoor units.
Information
The machine-specific information on engineering
and preparation can be found in this document’s
machine-specific engineering and preparation sec
-
tion.
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
Information
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 pipes with suitable insulating
material where they pass through open air between
the indoor and outdoor units, to prevent the forma-
tion of condensation. When passing above ground
outside, the insulating material must also have UV
protection.
Information
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.
6.2 Wall conduit
Whether the refrigerant pipes between the indoor and
outdoor units are to be routed above or below ground,
appropriate and system-specific wall conduits need to be
created through the outer wall of the building.
»
Ensure that the wall conduit is installed in an appro-
priate, plant-specific position layout.
»
Take the construction of the wall (tiles, concrete) into
account.
»
Take the prevailing groundwater situation into
account.
