When laying strip foundations we recommend the following
approach:
»
Dig out the foundation trench.
»
Place a drainage pipe along the base of the trench.
1 Reinforced strip foundation
2 Pipe liner for underground connecting lines
3 Drainage pipe (frostproof)
4 Gravel bed
»
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 stage, in the case of underground connec-
tion lines, this must be allowed for in the foundation
trench.
»
Construct the two reinforced strip foundations.
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.
Note
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:
»
Do not install the outdoor unit on a roof structure of
lightweight construction.
»
Note that when outdoor 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 out-
door unit.
