The diffuser is connected directly to the duct by
screwing or by riveting. The connection is sealed as

the ceiling with M8 drop rods using movable fixing
brackets. Alternatively the diffuser is installed fast to
the wall construction.

the exact location of the filter. Turn the brackets
below the filter and tighten them evenly.
Scan the filter for bypass leakages and correct the
tightness, if necessary
Reattach the front panel by pushing it until the springs
lock.

Adjustment
The airflow adjustment and shut off will be made with
PTS/A damper in the ductwork (tightness class 4 EN
1751). The pressure drop of the clean filter can be
used as a reference for airflow rate with a reasonable
accuracy. If there is no measurement unit available,
KELINNG MDA or MSD may be used as measurement
unit.
Constant or variable air flow & shut off
The airflow is adjusted with the aid of electrical
airflow management damper HFB/G in the ductwork.
Depending on the application the damper is ordered
either with constant or variable air volume settings.
See details of ordering from HFB documentation.
