Optimum (upright) installation of the overflow valve
Installation may only be performed
by authorised specialists.
NOTE
Setting and adjusting the overflow valve
The overflow valve is calibrated in the
factory and preset to a cracking pressure
of 200 mbar (2 m WS).
If it should be necessary to change the
default setting, proceed as follows:
1. Loosen the lock screw.
Using the hand wheel cap, the
cracking pressure can then be
adjusted continuously in a range
between 50 mbar and 500 mbar. The
desired value can be read directly
from the scale on the hand wheel
cap.
A setting and adjustment chart is not
needed.
The overflow valve must be set
so that the minimum flow value
is maintained in a closed heating
circuit.
NOTE
2. Using the lock screw, then secure
the selected position to prevent
accidental adjustment.
