Arrangement of the flexible hoses
>
Plan the exact installation site of the geoTHERM heat
pump and the pipe installation in such a way that the
supplied flexible connecting hoses can be connected to
the vibration isolation.

Requirements for the heating circuit
Only for installed external passive cooling:
b
Caution!
In the heating mode, there is a risk of
damage caused by the temperature fall-
ing below the dew point and by a build-up
of condensation.
All pipes in the heating circuit must be pro-
vided with vapour diffusion-tight insulation.
Radiator heating is not suitable for the
cooling with a Vaillant geoTHERM heat
pump.
>
Insulate all of the pipes in the heating
circuit using vapour diffusion-tight insu-
lation.
b
Caution!
In the cooling mode, there is a risk of
damage caused by the temperature fall-
ing below the dew point and by a build-up
of condensation.
Adequate cooling function is also guaran-
teed in a flow temperature of 20 °C.
>
Do not set the heating flow temperature
too low during cooling.
The heat pump is only suitable for connection to a closed
central heating installation. To ensure that the unit oper-
ates smoothly, the central heating installation must be set
up by authorised specialists in compliance with the applica-
ble regulations.
A heat pump is suited to low temperature heating systems.
For this reason, the heating installation must be designed to
reach low flow temperatures (ideally approx. 30 - 35 °C). In
addition, you must ensure that idle times from the power
company are taken into consideration.
To prevent energy losses and to protect against freezing, all
supply lines must have thermal insulation.
The pipelines must be free from contamination.
>
If required, clean the pipelines thoroughly before filling
them.
