2.
Having selected the appropriate mounting location, proceed with the following
steps:
2.1
Drill a tight-sealing Ø 13 mm hole into the duct.
2.2
Fix the flange onto the duct outer surface using the self-drilling screws
delivered with the unit. If you do not intend to use the flange, insert the
tube and fix the enclosure onto the duct. Mind the airflow direction (see
Fig. 2
and
Fig. 3
).

ATTENTION
Installation requirements: The DSMFX-2R must not be installed in turbulent air zones.
Ensure sufficiently long settling zones upstream and downstream of the tapping point.
A settling zone consists of a straight section of pipe or duct with no obstructions. Avoid
installation near filters, cooling coils, fans, etc. The sensor will achieve the optimal
result when the measurement is taken at least 7,5 duct diameters downstream and
at least 3 duct diameters upstream from any turns or flow obstructions.
ATTENTION
Installation of the unit near high EMI-emitting devices may lead to faulty
measurements. Use shielded wiring in areas with high EMI.
ATTENTION
Keep at least 15 cm distance between the sensor lines and the 230 VAC power lines.
2.3
Install the tube at the desired depth and; in case you use the flange, fix it via
the plastic white screw in the flexible flange.
2.4
Unscrew the cover of the unit to remove it and insert the connecting cables
through the cable gland of the unit.
2.5
Do the wiring according to the wiring diagram (see
Fig. 4
) adhering to the
information from section
Wiring and connections
