What are the key steps in the vertical installation method for LINEO PRO diffusers?

To install ERGOVENT LINEO PRO diffusers using the vertical installation method, first ensure you have the appropriate duct system, typically flexible plastic ducts of 75 mm, 90 mm or 125 mm. After fastening, seal any gaps with filler and paint the diffuser to match the ceiling, leaving a minimal slot for airflow. Ensure the diffuser is level for optimal performance. Finally, adjust airflow using the built-in balancing valve inside the diffuser. This method allows for seamless integration into your interior design while providing effective ventilation.
