Installing the outdoor unit

Transport
!
Please note
Impacts, compression and tensile loads can
cause damage to the outside panels of the
appliance.
Never apply loads/weight to the top, front or
side panels of the appliance.

Installation information

Types of installation
■ Floorstanding installation with line entry above
ground level
■ Floorstanding installation with line entry below
ground level
Wall mounting
■
Roof installation (flat or pitched roof)
■

Floorstanding installation

Particularly in more temperate and colder climate
zones (minus temperatures, snow and humidity), a dis-
tance to the substrate of at least 300 mm is required.
Secure the outdoor unit with supports for floorstand-
■
ing installation (accessories) onto a concrete founda-
tion.
Use ground anchors with a tensile force of at least
2.5 kN to secure the support to the foundation.
Where such supports cannot be used, install the out-
■
door unit freestanding on a solid base (provided on
site) with a height of at least 150 mm.
■ Take the weight of the outdoor unit into account: See
chapter "Specification".
Wall mounting
Use the wall mounting bracket set (accessories).
■
■ The wall must meet the structural requirements.
Use suitable fixing materials, depending on the wall
structure.
■ If there is no level access to the outdoor unit, ensure
it is easily accessible all year round for service and
maintenance. Provide sufficient maintenance areas.
Install suitable protection equipment, e.g. fall protec-
tion.
Roof installation
Flat roof installation
Note
Due to the higher static loads (roof/wind load) and the
higher acoustic requirements for roof installation, the
structural calculations and sound concept require input
from specialist design engineers.
!
Please note
If the compressor in the outdoor unit is tilted too
far, lubricant will enter the refrigerant circuit and
damage the appliance.
Max. tilting angle: 45° for approx. 4 min, other-
wise 30°
If the outdoor unit is to be installed on a flat roof, in
addition to the requirements for floor and wall installa-
tion, the planning measures to be taken into account
include the following:
■ As the outdoor unit is located higher up when instal-
led on a flat roof, the propagation of operating noise
is more intense than when it is installed on the
ground. Roof surfaces are normally more reverber-
ant than areas on the ground.
To prevent noise nuisance, install the outdoor unit at
a sufficient distance from neighbouring buildings. If
required, provide suitable noise reduction measures.
Take into account sound reflection from the surfaces
of buildings when analysing sound propagation: See
technical guide.
■ Provide on-site wind protection measures where
necessary, e.g. screens, walls, etc.
■ Check to ensure that the installed height of the out-
door unit does not exceed the permissible building
height, e.g. as specified in outline planning restric-
tions.
Provide easy, year-round access to the outdoor unit
■
for service and maintenance. Provide sufficient main-
tenance areas which comply with the safety regula-
tions.
Install suitable protection equipment which complies
with the safety regulations, e.g. anchorage points.
Recommendation: Install the heat pump on a steel-
■
reinforced concrete roof
■ Installation on flat roofs with a low weight per unit
area (e.g. roofs made from timber rafters or trapezoi-
dal sheet metal) is not permissible.
With flat roof installation, considerable wind loads
■
may occur, depending on the relevant wind zone and
the height of the building. Have the substructure
designed according to DIN 1991-1-4 by a specialist
design engineer.
■ The higher roof and wind loads must be taken into
account in the structural calculations and the fixture
system of the outdoor unit.
It is essential to comply with the specifications provi-
ded by the design engineer with regard to structural
calculations, distances from building edges and the
sound concept.
■ Where design casings are concerned, check that
these are able to withstand wind and snow loads.
