Install the duct or wall-liner taking care to seal at both ends between it and
the wall using proprietary waterproof mastic.
3. Remove the front cover of the fan by pulling the fan back plate straight off
(Fig. 1).
4. Position the fan in the duct and mark the four retaining screw positions
through the backplate. Fit screw anchors suitable for the wall construction.
5. Remove the central terminal cover by first removing the central Posidriv®
retaining screw (Fig. 2).
6. Unclip and remove the fan wall-mounting plate (Fig. 3).
