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 Drainage pipe (frostproof)
3 Gravel bed
»
Fill the foundation trench with coarse gravel.
»
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.
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:
»
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
outdoor unit.
1 Flat roof
2 Refrigerant lines in open air (enclosed in thermal in-
sulation with UV protection)
3 2 concrete slabs attached with flexible adhesive (per
leg of the outdoor unit). The outdoor unit is affixed to
the concrete slabs
4 Anti-vibration mounts
When installing the outdoor unit on a freestanding car port,
a garage roof or a storage space roof, please note the
following:
»
Ensure that the outdoor unit is adequately secured,
with regard to the wind load occurring at the installa-
tion location.
»
Take account of the concentrated load arising from
the dead weight of the outdoor unit (including the
roof fixings) and the surface load caused by possible
build-up of ice.
»
Ensure suitable structure-borne vibration separation
between the outdoor unit and the installation points
on the roof.
