Installation instructions
Safety instructions
The installation has to be done by qualified per-
sonnel. Read the instructions carefully right up to
the end before starting to mount the device.
The current laws and regulations have to be
observed, especially EN 1434 part 1+6, (in Ger-
many also AGFW directive FW202 and DIN 4713
part 4 and the initial verification directive).
At devices with communication 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 instal-
lation.
