Adjustment


ADJUSTMENT

In order to enable adjustment and measurement of the airflow rate, it is recommended that you connect the diffuser to the special BDR plenum equipped with the MEM module.

The airflow rate can be adjusted and measured only when the grille is connected to the special BDR plenum.
Define the exhaust airflow rate by measuring the pressure difference between the measurement tap on the special BDR plenum and the room air. The corresponding airflow rate is calculated using the formula below.


Adjust the airflow rate by turning the control spindle of the MEM.

Airflow adjustment damper OD

The airflow rate is adjusted by turning the damper blades behind the grille with a screwdriver. The measurement is performed when the grille is installed.

Servicing


SERVICING


Remove the grille by gently drawing it out by the frame. Use a screwdriver if necessary.
Clean the parts by wiping with a damp cloth.
The filter can be removed for replacement by sliding sideways.
