Plastering the installation kit on the inside
NOTICE
► Prepare the substrate suitably
before plastering.
► Make sure that the signal cover (item
1 in Fig. 20) is seated in the plaster
► Cut off any excess expanding foam
on the wall box.
► Apply the plaster scrim M-WRG-II PG
(item 3 in Fig. 20) to the installation
kit and the solid wall.
NOTICE
Applying plaster scrim will minimise
subsequent cracking of the plaster.
► Plaster the internal wall. The plaster forms the airtight layer on the internal wall. The
expanding foam does not act as an airtight layer.
► When plastering, make sure that the plaster ends flush with the plastering trim. The
following situations are not permitted:
— The plastering trim (item 1 in Fig. 21) protrudes above the plaster
(item 2 in Fig. 21).
— The plaster (item 2 in Fig. 22) protrudes above the plastering trim
(item 1 in Fig. 22).
