II. 2.3.4 Checking the correct installation of the frame-grille assembly (for all models)
The frame must not show signs of deformity caused by excessive traction. It
must be centered with respect to the false ceiling and, above all, it must

leakage (B) inside the false ceiling. After installing the assembly, check that
the gap between the frame and the false ceiling is under 5 mm.
