3.1.7.2 BD1 installation
BD1 installation should always be in a cable
trunk.
The sensor should always be tilted at least 45°
from horizontal to ensure that fluid in the tube can
flow away from the sensor. To keep the sensor in
preferred position it is to be mounted on the
supplied mounting plate (pn60045400). The
sensor cord should go out from beneath the sensor
to prevent water from running down the cord into
the sensor. Cable ties are used to fix the tube to
the plate. Be careful not to mount the cable ties to
tight as this can damage the tube.
If possible BD1 should be in a vertically mounted
cable trunk. Horizontally mounted cable trunks
can be used but then the cable trunk opening must
point outwards and not upwards! This is to ensure
that the tube and the sensor can be mounted in a
way so that the fluid in the tube will flow away
from the sensor
Where and how the sensor should be mounted on
the tube is described in Appendix 1 -2
