Diffuser installation is a quick and straightforward process that does not require highly specialized tools. It is recommended to follow standard ventilation system installation guidelines.
Mounting preparation
Before starting, ensure you have the correct diameter duct and sufficient space in the ceiling or wall to accommodate the mounting ring.
Duct and ring connection
The included mounting ring connects directly to the ductwork. To ensure a completely airtight seal, it is recommended to use appropriate sealing tapes or mastics.
Diffuser installation
Once the mounting ring is securely in place, the diffuser valve is easily inserted into the ring. The mechanism holds the diffuser firmly in position.
Airflow adjustment
The airflow is accurately adjusted by rotating the central cone of the diffuser. Once the required position is set according to the ventilation design, the cone is locked in place.
Cleaning and maintenance
The painted surface repels dirt, but if necessary, the diffuser can be easily wiped clean with a damp cloth. Regular cleaning ensures long-lasting aesthetics and uninterrupted airflow.
