General Installation Instructions
When choosing the installation site, ensure that the specified limit
values (see "Technical Specifications") are not exceeded.
Select suitable measures to prevent the medium from freezing.
If the flow switch is to be used in ambient temperatures of < 39.2 °F,
do not carry out any operation beforehand with pure water, e.g. a test
run. Residual water in the flow switch can result in frost damage.
Firstly, clean the pipe system in which the flow switch is to be installed
and remove any magnetic particles, e.g. welding residue.
The straight in- and outlet pipe (in front of and behind the flow switch)
has to be at least 5 x ID.
The nominal installation position of the flow switch is an "upright
standing position" in horizontal pipework.
The switches should only be installed in a vertical position, deviation
max. 45 (Fig. 1).
Please contact the manufacturer if other installation positions are
desired.
Please make sure that there are no external magnetic fields in the
immediate vicinity of the flow switch, since these can impair device
functioning (Fig. 2).
There is an arrow on the flow switch. Ensure that this arrow is parallel
with the pipe shaft and is facing in the direction of flow
during installation (Fig. 2).
The brass and Plastic union nuts ¾" BSP have a tightening torque of
18.439 ... 22.127 ft lb.
The plastic union nuts have a tightening torque of 5.163 ... 5.901 ft lb.
