MOUNTING ON THE CEILING
The Vallox 125 MV units (excluding model B) can be equipped
with an optional ceiling mounting plate.
Installing the ventilation unit to the ceiling
mounting plate
CAUTION
The ventilation unit is very heavy. Do not perform this
procedure alone. Use appropriate lifting equipment,
where necessary.
1. Check that the condensate insulation rings are in place in
the outlet collars below the ceiling mounting plate.
2. Pull the operating levers (A) out and lock them by turning
them towards the outer sides of the unit.
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 to the rear wall between
the ceiling mounting plate and the ventilation unit. Lift
the ventilation unit up against the ceiling mounting plate
by releasing the locking of the levers (A) by turning them
towards the center of the unit; the levers will lock the unit
to the ceiling mounting plate. Where needed, guide the
mounting hooks on the ceiling mounting plate (B) to the
grooves on the side panels of the ventilation unit. In the
locked position, the levers are at the same level as the front
edge of the ceiling mounting plate.
5. Where required, the unit can be detached from the ceiling
mounting plate. Remove the door of the unit, lift the unit
slightly upwards, pull out both operating levers (A) and lock
them (see section 2).
Attic floor penetration plate
The attic floor penetration plate (D) is optional. When an
insulated attic floor penetration plate is used, the airtightness of
the vapour barrier must be ensured.
The attic floor penetration plate is installed at the same level as
the rear wall of the ventilation unit. The minimum distance of the
attic floor penetration plate from the rear wall is 10 mm, and the
width varies depending on the model. Follow the model-specific
instructions on the penetration plate.
