Fixing the wall box
►
Fix the wall box (item 1 in Fig. 16) in posi-
tion in the wall breakthrough using wedges
or air cushions (item 2 in Fig. 16).
►
Use the spirit level (item 3 in Fig. 16) to
align the wall box so that it is perpendicular
and flush with the wall.
NOTE
►
Make sure that the wall box is perpendicu-
lar as this is the only way to ensure that any
condensation will be carried outside by the
2° pipe fall.
►
Fix the filler piece, if needed, to the external
wall with wedges or air cushions.
NOTE
The plastering trim is 15 mm deep (see Fig. 17).
►
If the depth of plaster should be more than
15 mm, position the wall box so that it
protrudes sufficiently out of the solid wall.
If you do not do this, there is a risk that the
ventilation unit will not work correctly.
►
If the interior wall is not perpendicular or
flat, align the front surface of the plastering
trim (item 1 in Fig. 17) parallel to a plaster
stop bead running vertically.
