INSTALLING THE VENTILATION UNIT
TO THE CEILING MOUNTING PLATE
CAUTION
The ventilation unit is very heavy. Do not perform this
procedure alone.
1. Remove the front panel of the top part of the unit (1) (leave
it hanging from the air flow measuring tubes).
2. Place the connection box cables into the slot in the top part
of the side panel (2) and pull the connection box to the side
of the unit so that the cables remain in the slot.
3. Ensure that the condensing water insulation is in place in
the duct outlets of the extract air duct and of the duct that
comes to the unit from outside.
4. Lift the unit in its place on the ceiling mounting plate until
both locking wings (3) lock on the outer edge of the side
plate of the unit.
5. Visually check the tightness of the duct outlets and the
unobstructed passage of measuring tubes and electric
cables.
6. Put the front panel of the top part back in place.
Attic floor penetration plate
The attic floor penetration plate is optional. When an attic floor
penetration plate is used, the tightness of the vapour barrier
has to be ensured.
