To be mounted below a ceiling. Remove the front panel. Hold the unit in position and fix it with screws through to back plate. Refit the front panel. Unless requested otherwise, the side slots are locked in a closed position.

See selection chart for maximum airflow (l/s) for a ceiling mounted unit at 3 °C under temprature 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 detergent solution.

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