Ensure that the outdoor unit is adequately secured,
paying regard to the wind load occurring at the instal-
lation location.
CAUTION: Risk of slipping
If drainage for condensation is inadequate, ice can
build up in winter in the area around the outdoor
unit.
»
Ensure drainage for condensation is sufficient
even at low temperatures.

Information
Insulation used beneath the soil must be made of
a closed-cell material. Otherwise, the thermal in-
sulation of the material will be impaired.

»
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.
»
Fill the underground waste pipes with concrete.
