It is essential that the safety instructions
provided in these instructions for the shut-off
device or shutter are observed.
1. Switch off mains fuse, secure against being
accidentally switched back on and position a
visible warning sign.
2. Mark fixing holes on wall: 3x fixing holes for
lower part of housing. For APB, also 1x fixing
hole for tab of metal exhaust socket. It is es-
sential that the permissible installation posi-
tions are observed.
3. Drill fixing holes and insert dowels. Suitable
mounting material is to be provided by the
customer.
4. Check ease of movement of shut-off shutter/
backflow preventer. When installed, the shut-
off shutter/backflow preventer must close
automatically.
5. When the power cable is surface installed at
position “S”, knock out the housing segment at
the nominal opening and cut small recesses
into the cross struts on the rear of the lower
part of the housing to route the ducts.
NOTICE Danger of short-circuits and damage
to the unit. If the power cable is incorrectly
fed or if the cable grommet is not fitted cor-
rectly, water may penetrate into the fan hous-
ing. The degree of protection cannot be guar-
anteed.
Pierce the cable grommet so that it tightly seals
the power cable. Guide the surface-mounted or
flush-mounted cables correctly into the intended
cable grommet.
6. Pierce a round opening in the cable grommet
with a grommet puncher.
