The grille is designed to be mounted flush with the wall or ceiling. The internal mechanism is accessible for cleaning and maintenance.

Installation:

The BAHIA CURVE S should be installed in humid or technical rooms such as bathrooms, WCs, or utility rooms. It should be positioned high on a vertical wall or on the ceiling, at least 1.80 meters above the floor. Ensure at least 20 cm of clearance around the grille for accessibility and removal. The connection to the ductwork should be airtight, ideally using a cuff. Versions with an 80 mm spigot can be directly fitted into cuffs, rigid, or semi-rigid ducts. For ceiling installations or mounting above furniture, a cord return (code 11015001) may be needed. For electric models, a 9V alkaline battery (type 6LR61) and a push button (code 11026011) are required. The grilles operate within a pressure range of 80-160 Pa. Extraction grilles require annual maintenance and verification. Connecting a mechanical hood to the VMC system is prohibited.
