WARNING!
Installation and management
of the device is permitted solely
by authorised and appropriately
trained personnel equipped with
sufficient technical experience.
Prior to installation make certain that the
two sections of tube are even to prevent
mechanical stress, clean them with care (es-
pecially in the case of empty tubes) and let
water run for a while, using a stub pipe on
the tube instead of the meter.
If there is no water in the tube, before in-
stalling the meter open the valve upstream
from the meter. This is necessary because
the valve can cause air suction at the end of
installation, which could damage the meter.
Before using the meter, first fully remove air
from the pipe and the meter itself. The in-
terception/adjustment valves must be fully
open when doing this. Open the valve at the
start first and then the valve at the end.
