5.3. CABLEADO
The length of the cable in the moun-
ting tube is dependent on structural
conditions. Make sure that the fan
unit can be easily connected up and
that the cable does not unnecessa-
rily block the airfl ow.
Use slits in the wall or cable ducts to lead the ca-
bles to the hole in the wall. Make sure that the
length of the cable in the mounting tube corres-
ponds to the thickness of the wall minus 150 mm.
Wire the plug for connecting up the fan unit (see
Electrical installation). Should cables with a dia-
meter › 6.1 mm be used, the top layer of insula-
tion will need to be removed to prevent problems
with the further installation.
5.4. INSTALLATION OF THE OUTSIDE COVER
Once all work on the building's facade has been fi -
nished, the outside cover can be installed. Remove
the plastering cover and insert the outside cover
into the mounting tube. When inserting it, make
sure that the air vent points downwards and sits
tight. Due to the special mounting slats, the outsi-
de cover can be installed without any tools and sits
tight in the mounting tube.
When using an outside grille, make sure that the
grille is properly positioned with the curved slats
pointing downwards. Before doing this, the stop-
per (part of the set) must be glued to the outward-
facing upper edge on the inside of the mounting
tube, where it acts as a stopper for the heat ex-
changer unit. Then screw (screws at the side) the
outside grille to the mounting tube.
Should you be using an outside hood
instead of a grille, please refer to its
separate installation instructions.
5.5. POSITIONING OF THE FAN AND HEAT
EXCHANGER UNIT
Once all work has been fi nished on the inside walls
and the outside grille or hood has been installed,
the fan and heat exchanger units can be installed.
Start by connecting the two units. This is done by
sliding the fan unit over the front end of the heat
exchanger unit. Then insert the two into the moun-
ting tube (2), with the insect fi lter facing outwards.
Push the unit carefully into the mounting tube until
it touches the outside cover.
The strap must point inwards
(towards the room), allowing the
heat exchanger to be removed for
maintenance.
5.6. INSERTING THE INSIDE COVER
Once all work inside the building has been com-
pleted, the inside cover can be installed. Place the
