! The expansion tank provided is pre-pressurised to approx. 1 bar, and therefore
needs to be adjusted to a suitable pre-pressure for the building. This must be
done before the system is filled with water.
If an open expansion tank is used, the distance between the expansion tank and
the highest placed radiator must not be below 2.5 m, in order to avoid introducing
oxygen into the system.
If a heat pump is connected with another heat source, e.g. an existing boiler, the
installations must have separate expansion vessels.

The pre-pressure in the expansion tank is calculated according to the height
(H) between the highest-positioned radiator and the expansion tank. The
pre-pressure must be checked/set before the system is filled with water.
The system pressure must be set 0.3 bar higher than the pre-pressure in
the expansion tank. For example, a pre-pressure of 1.0 bar (5 mvp) means a
maximum permitted height difference of 10 m.
5.6.3 Adjust the pre-assembled expansion tank to the right pre-pressure by
using the valve to raise or lower the pressure.
