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.
NOTE
Mount the ventilation
unit in a place where
the temperature does
not fall below +10°C.
