To be recessed in a ceiling.
Hang the unit so that its flange overlaps the underside of the false ceiling. After the front plate has been screwed in position the that the false ceiling is completed. Unless requested otherwise, the side slots are locked in the closed position.

 

See selection chart for maximum airflow (l/s) for a ceiling mounted unit at 3°C under temperature and 0.2 m/s velocity at 0.4 m ( Y₀₂) distance from the unit.

The unit can be cleaned by removing the front panel. Altering the airflow must be carried out using the external adjustment damper. To achieve the correct air flow and side induction/impulse pattern, either use an air velocity instrument or smoke gun. The side slots are adjusted to the desired air velocity.

Clean with water and a mild detergant solution.

Open slot (%) / airflow (l/s) at Y₀₂ =0,4m at ΔT 3°C.
