Filling gaps around the wall box with foam
NOTICE
► Check that the plaster cover (item 1
in Fig. 15 on page 22) is inserted
before filling with foam.
► Check that the wall box is seated
correctly. Once you have used the
foam, you will not be able to align it
further.
► Fill the gaps between the wall box
and wall breakthrough all around and
continuously with expanding foam
(item 1 in Fig. 18) or using another
suitable filling material.
► Once the foam has hardened,
remove any wedges that extend beyond the solid wall.
