»
In the case of underground connecting lines, allow for
the pipe liner.
»
Fill the foundation trench with coarse gravel. If the
pipe liner (with refrigerant lines) is to be installed at
a later point, in the case of underground connec-
tion lines, this must be allowed for in the foundation
trench.
»
Construct the two reinforced strip foundations.
9.3.3 Installing on flat roofs
WARNING: Risk of falling
Working on a flat roof without fall protection con -
stitutes a risk.
»
When working on a flat roof, observe the laws
relating to occupational safety in your region.

Always be aware of the open edge.
i
Information
Avoid installing the outdoor unit on the roof above
residential buildings or on car ports attached to res-
idential buildings, due to the risk of structure-borne
noise transmission.
Loads and stresses on roof structure
»
Note that when outside temperatures are very low,
ice can form beneath the outdoor unit.
»
In terms of roof structure loads, allow for an ice load
of 400 kg/m² in addition to the dead weight of the
outdoor unit.
