Duct connection
The plenum box has a spigot for duct connection.
Variants with a double lip seal allow for a sufficiently
tight connection; additional sealing is not required.
Initial commissioning, maintenance and
cleaning
Initial commissioning
Before you start commissioning:
Check that the air terminal devices are cor-
rectly seated.
Remove protective film, if any.
Ensure that all air terminal devices are clean
and free from residues and foreign matter.
Check that electrical connections (if any) have
been correctly made.
Ensure that the devices have been correctly
fixed and connected to the ducting.
For commissioning see also VDI 6022, part 1 – 'Hy-
giene requirements for ventilation and air-condi-
tioning systems and units'.
Volume flow rate balancing
When several diffusers are connected to just one
volume flow controller, it may be necessary to bal-
ance the volume flow rates.
AIRNAMIC
The diffuser face can be removed to access the
damper blade; the damper blade can then be set in
15° intervals between 0 and 90°
