Installing the ventilation unit to the ceiling
mounting plate
1. Install the ceiling mounting plate with M8 thread bars so that
it is horizontally level.
NOTE
The end of the thread bars must be 5 mm or less below
the fastening nut. Do not fasten the ceiling mounting plate
too tight to the ceiling. Ensure that the sliding bars move
and restore to their original position by pulling from the
operating levers (A). The top edge of the white covering
strip of the ceiling mounting plate can be installed against
the ceiling. Alternatively, a concealed mounting method
can be used, in which case the ceiling can be 20 mm
below the top of the white covering strip.
2. 096 - Install the insulation washers into the outlet collars of
the ventilation unit.
110 - Ensure that the insulation washers are in place in the
outlet collars below the ceiling mounting plate.
3. Remove the door before installing the ventilation unit to the
ceiling mounting plate.
4. Lift the ventilation unit close to the ceiling mounting plate
and feed the cables and the connection box through the
hole in the ceiling mounting plate on top of the ceiling.
NOTE
Remember to make a service door in the ceiling so that
the cables and the connection box can be accessed.
The distance between the service door and the ceiling
mounting plate must be around 500 mm.
Alternatively, the cables can be fed between the ceiling
mounting plate and the ventilation unit to the rear wall.
When the ventilation unit is lifted against the ceiling
mounting plate, the unit locks in place. Where needed, guide
the mounting hooks on the ceiling mounting plate (B) to the
grooves on the side panels of the ventilation unit. There are
operating levers (A) on the front bottom corners of the ceiling
mounting plate. When the levers have been restored to the
same level with the white covering strip of the ceiling mounting
plate, the unit has been locked in place.
5. Where required, the unit can be detached from the ceiling
mounting plate. Remove the door of the unit. Lift the unit
slightly upwards and pull simultaneously from both operating
levers (A) of the ceiling mounting plate to detach the unit
from the ceiling mounting plate.
Attic floor penetration plate
The attic floor penetration plate (F) is optional. When an attic
floor penetration plate is used, the tightness of the vapour
barrier has to be ensured.
The minimum distance of the attic floor penetration plate from
the rear wall is 5mm. The minimum distance of the attic floor
penetration plate from the side walls is 15mm.
TIP
You can detach the unit
from the ceiling mounting
plate by pulling the
spring-loaded moulding
to the direction shown by
the arrow (more detailed
information provided
with the ceiling mounting
plate).
