Material damage
Unsuitable fill water can damage your system due
to scaling and corrosion.
»
If necessary, ensure that the fill water is pro -
fessionally softened and demineralised.
10.3.2 Safety valve drain
i Information
The indoor unit has an internal safety valve (DHW,
heating).
»
Observe national and regional regulations re-
garding the design of the drain and prescribed
regular operational tests.
i
Information
The maximum operating pressure of the heat
transfer medium is 3 bar. However, due to closing
pressure differences, the safety valve may begin
to open from a pressure of 2.4 bar.
If the valve is triggered, the water exits via a hose on the
rear of the indoor unit.
»
The safety valve drain should be dimensioned such
that the water can drain unobstructed via an open
and readily visible waste water drain.
»
Install the hose with a consistent fall to the drain.
Avoid kinking the hose.

Venting the heating system
On the AIR 7, AIR 11 and AIR 18 (M2 hydraulic variant)
indoor units, the multifunctional assembly (MFA) has a
quick-action air vent valve for venting the heating system.
»
Before venting, open the quick-action air vent valve
on the multifunctional assembly (MFA). Do this by
pulling the red cover on the valve.
Material damage
During venting, water can escape from the air out-
let on the quick-action air vent valve.
»
Ensure that the electronics in the indoor unit
do not become wet.
