1.5 Legal regulations and directives
This heat pump is designed for use in a domestic environment
according to Article 1, Paragraph 2 k) of EU directive 2006/42/
EC (Machinery Directive) and is thus subject to the require-
ments of EU directive 2014/35/EU (low-voltage directive). It is
thus also intended for use by non-professionals for heating
shops, offices and other similar working environments, agricul-
tural establishments and hotels, guest houses and other resi-
dential buildings.
The construction and design comply with all relevant EC direc-
tives and DIN/VDE regulations (see CE declaration of conform-
ity).

5Installation
5.1 Indoor unit
5.1.1 General
The unit should always be installed indoors on a level, smooth
wall. Maintenance work can be carried out easily from the oper-
ator side (a larger minimum distance at the side is required; as-
sembly clearance of 5 cm must be adhered to). This can be en-
sured by maintaining a distance of approx. 1 m at the
front. The indoor unit should be mounted at a height of approx.
1.20 m. Installation must be carried out in a frost-proof room
and using short pipelines.
NOTE
ººººº
Setup and installation must be performed by an authorised
specialist company.
CAUTION!
!!
The unit must not be mounted or operated near a naked
flame, gas-powered devices, electric heaters or any other
comparable source of ignition.
CAUTION!
!
!
The unit must not be installed in a room that is also used as a
workplace or workshop (risk of ignition due to flying sparks).
CAUTION!
!
!
When installing the unit, make sure that no ventilation
openings are blocked.
NOTE
º
ºººº
The heat pump is not intended for use above 2000 metres
(mean sea level).
5.2 Outdoor unit
It is advisable to install the outdoor unit close to a wall, on a
foundation separate from the building with a minimum
clearance of 0.3 m on the intake side (Fig. 5.1 + Fig. 5.2).
If a canopy is mounted to protect from direct sunlight, rain
or snow it must not impede the heat exchange of the unit.
In the case of a free-standing installation, the foundation is
to be connected on the intake side, flush with the unit. This
will prevent snow from building up between the foundation
and the evaporator.
The minimum clearances (Fig. 5.1) indicated must be ad-
hered to.
When selecting an installation location, it should be en-
sured where possible that persons are not going to be in-
convenienced by the circulation of warm/cold air or by
noise emissions.
The condensate tray offers various options for condensate
draining. In warmer regions, the condensate can drain from
the device freely. In regions with longer periods of frost,
controlled condensate draining is required.

Abb. 5.3
If the unit is installed on a wall bracket, special attention must
be paid to separate any sound to the building.
If the wall bracket installation option is selected, the following
points must be observed:
Fit rubber buffers
Take the weight of the outdoor unit into account
Ensure that the wall bracket is no higher than 1 m above
the ground
Ensure that minimum clearances are adhered to
Abb. 5.4
When installing several outdoor units next to each other, the
specified distances must be observed. Furthermore, if several
outdoor units are installed, it must be ensured that the air inlets
and outlets do not affect any of the other units.
NOTE
º
ºººº
Structural influences must be observed for installation close
to walls. No windows or doors should be present in the area
surrounding the air outlet of the fan.
NOTE
º
ºººº
Installation in a hollow or in an inner courtyard is not
permitted because cooled air collects at ground level and is
drawn in again by the heat pump during extended periods of
operation.
CAUTION!
!!
Incorrect installation, maintenance or repair may increase the
risk of cracks in the installed piping, resulting in property
damage.
CAUTION!
!
!
Improper installation of the unit may restrict operation of the
system.
5.2.1 Wall opening, split lines and electric
wires
Please proceed as follows when laying split lines and electric
wires:
Drill a 70 mm opening for the pipework using a core drill.
The opening for the pipework should be slightly inclined
towards the outdoor unit, so that no rainwater can pene-
trate the building.
During installation work, please ensure that connection points
are easily accessible for maintenance and repair purposes.
CAUTION!
!
!
Care must be taken to ensure that the connections and lines
are not subjected to any mechanical loads.
CAUTION!
!
!
Connection lines must not exhibit any mechanical damage.
5.2.2 Wall opening for condensate drain
For the safe drainage of the condensate, the condensate drain
must be positioned in such a way that no frost build-up can oc-
cur. The frost line can vary according to the climatic region. The
regulations of the countries in question must be observed.
When laying the condensate connection, pay attention to the
slope that must be maintained.
