Safety instructions for installation

Read these instructions care-
fully right up to the end before
starting to mount the device! The

qualified professional personnel.
The current laws and regulations
have to be observed, especially EN
1434 part 1+6, (in Germany also
AGFW directive FW202, FW 218 and

cation interfaces or mains supply
the general technical rules and the
correspondent regulations have to
be followed.
While demounting flow sensors
and temperature sensors make
sure no heating water escapes
from the pipe. This can cause
burns! Close valves and release
pressure before installation.
