Collect media safely.
Dispose of the media in an environmentally sound
manner in accordance with to the local regula-
tions.
2.6 Avoid material damage
The ambient air at the heat pump’s installation site, as
well as the air drawn in as a heat source, must not
contain any corrosive components!
Constituents such as
Ammonia
Sulphur
Chlorine

the condenser and any heat exchangers have been
drained completely for the event of freezing temper-
atures. Residual water in heat exchangers and con-
densers can result in damage to the components.
Completely drain the system and the condenser,
and open vent valves.
Blow them clear with compressed air, if required.
Improper action
Requirements for minimum scale and corrosion dam-
age in hot water heating systems:
Professional planning and commissioning
Closed system with regard to corrosion
Integration of an adequately dimensioned pres-
sure maintenance
Use of demineralized water heating water or
VDI 2035 water
Regular servicing and maintenance
If a system is not planned, commissioned and operat-
ed in accordance with the given requirements, there
will be a risk of the following damage and malfunc-
tions:
Malfunctions and failure of components, e.g.
pumps, valves
Internal and external leaks, e.g. at heat exchangers
Reduction in cross-section and blockages in com-
ponents, e.g. heat exchangers, pipes, pumps

hot water or for heating the building. The temperatures
required and the use are controlled by the heat pump
controller. Any required reheating, support in screed
drying or increase in the domestic hot water temper-
ature can be carried out using an electric heating ele-
ment, which is activated by the heat pump controller
as required.
The integrated vibration decoupling for the hydraulic
system prevents structure-borne sound and vibrations

5.4 Installation
CAUTION!
In the air outlet area, the air temperature is
approx. 5 K below the ambient temperature.
Under certain climatic conditions an ice lay-
er can therefore develop in the air outlet area.
Install the heat pump so that the air blower
does not discharge into footpath areas .
NOTE
Always comply with the installation plan for
the respective model. Note the size and mini-
mum clearances.
