Safety valve discharge:
In case of overpressure, water escapes through
the discharge of the safety valve. Ensure that
the escaping water is discharged safely.
Attention:
Do not connect the discharge of the
safety valve rigidly to a discharge
line at a wall as this leads to noise
transmission.

Positions 2 to 12 can be pre-
