5 Installation
5.1 Indoor unit
The unit should always be installed indoors on a level, smooth
and horizontal surface. The indoor unit must be installed in a way
that allows maintenance work to be carried out from the operator
side without hindrance. This can be ensured by maintaining a
clearance of 1 m at the front. The space required (approx. 30
cm, see dimension drawing) for replacing the protective anode
must be taken into consideration when determining the required
height of the installation room. It must be installed in a room pro-
tected from frost and with short pipe runs.
ATTENTION!
In an unfilled state (buffer tank and domestic hot water cylinder without
water), the device has a tendency to tilt in the direction of the hydraulic
assembly. Do not lean on the rear of the unit!
Setup and installation must be performed by an authorised spe-
cialist company.
Fig. 5.1: Clearances – indoor unit
If the indoor unit is installed on an upper floor, the load-bearing
capacity of the ceiling should be checked. On account of the
acoustics, measures for isolating possible vibrations should also
be very carefully planned in advance. Installation on floors above
wooden ceilings is not recommended.
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 clear-
ance of 0.3 m on the intake side (Fig. 5.2 + Fig. 5.3).
If a canopy is mounted to protect from direct sunlight, rain or
snow it must not impede the heat exchange of the device.
In the case of a free-standing installation, the foundation is
to be connected on the intake side, flush with the device.
This will prevent snow from building up between the founda-
tion and the evaporator.
The minimum clearances (Fig. 5.2) indicated must be ad-
hered to.
When selecting an installation location, it should be ensured
where possible that persons are not going to be inconven-
ienced by the circulation of warm/cold air or by noise emis-
sions.
The condensate tray offers various options for the conden-
sate drain. In warmer regions, the condensate can drain
from the device freely. In regions with longer periods of frost,
a controlled condensate drain is required.
