Mounting preparation
Cut a hole of the appropriate diameter (100 mm or 125 mm) in the ceiling. Make sure there is enough flat area around the hole for the mounting ring and the outer diffuser plate to fit snugly.
Duct connection
Connect the ventilation system duct to the mounting ring spigot. To prevent vibrations, the use of flexible connectors is recommended. Ensure system tightness.
Diffuser installation
Once the mounting ring is attached to the ceiling, simply insert the diffuser itself into the ring. The design allows the device to lock firmly in place.
Airflow adjustment
Airflow is very easily adjusted by rotating the central disc, widening or closing the air passage gap. This allows for achieving the perfect balance in the system.
Cleaning and maintenance
The glossy epoxy paint coating effectively repels dirt. If necessary, simply wipe the visible plate with a soft, damp cloth, avoiding harsh chemical cleaners.
