4.13.1 Assembly of the heating system
a
Caution!
Danger of falling below the dew point and
condensate formation!
All the pipes of the heating circuit must
be insulated leak-proof against vapour
diffusion.
Radiator heatings are not suitable for
the operation with a Vaillant heat pump
geoTHERM exclusive.
a
Caution!
Danger of falling below the dew point and
condensate formation!
The heating flow temperature must not
be set too low in the cooling mode. Ade-
quate cooling function is also guaranteed
in a flowtemperature of 20 °C.
a
Caution!
Risk of damage!
In order to be able to clear any possible
overpressure, the heat pump must be
connected to an expansion vessel and an
expansion relief valve, at least DN 20
with a maximum opening pressure of
3 bar (not supplied).
H
Danger!
Risk of scalding!
The blow-off line on the expansion relief
valve must be the size of the valve's
outlet aperture and be installed in a
frost-free environment. It must remain
constantly open. It must be fitted in
such a way that persons are not endan-
gered by hot water or steam when it
blows off.
We recommend the installation of a Vail-
lant safety assembly and tundish.
• Fit the heating flow and return lines with all compo-
nents.
• Insulate all the pipes.
4.13.2 Assembly of the brine circuit
• Install the heat source pipes and all their associated
components.

Note!
The brine expansion tank has a capacity
of approx. 6 litres and is thus adequate
for brine circuits up to a maximum of
1900 litres.
