Sound insulation and vibration isolation
Information on installing the cables and lines
Wall outlet:
■
No wall outlet where load bearing sections, lintels,
damp proofing elements (e.g. vapour barriers), etc.
are located.
■
No structure-borne noise transmission, i.e. avoid
contact between metal (refrigerant line) and the
building structure.
Routing the cables and lines:
■
Route cables free of strain and separated from the
refrigerant lines.
■
Route the hot gas line with pipe bends. This reduces
the transmission of vibrations to the pipe wall.
■
Use a tighter pipe bend for vibration compensation
on a shorter hot gas line than on a longer hot gas
line.
■
Insulate all refrigerant lines.
Securing the refrigerant lines:
■
Secure refrigerant lines using only pipe clips with soft
elastic insulating lining (EPDM).
■
Secure the pipe bend for vibration compensation at
the end of the bend with a pipe clip (towards the
external wall).
■
Secure refrigerant lines with pipe clips at intervals of
max. 2.0 m. We recommend securing the refrigerant
lines with pipe clips at intervals of 1.5 m.
■
Recommendation: Mount pipe clips only on compo-
nents with a mass per unit area ≥ 250 kg/m
2
.
■
Do not install refrigerant lines on partition walls or
ceilings to rooms that require a low noise level (e.g.
bedrooms).
