MOUNTING ON THE WALL
NOTE
Avoid mounting the unit on a hollow, echoing partition wall or
on a bedroom wall, or prevent the conduction of sound.
The minimum distance between the top of the unit and the
finished ceiling surface is 30 mm. Note that during mounting
the unit rises 10 mm higher than the final height.
Mount the ventilation unit on the wall with a mounting plate, as
shown in the adjacent figure. Make sure that the unit is horizontally
level after mounting.
MOUNTING ON THE CEILING
Model Vallox 90 MV can be equipped with an optional ceiling
mount plate. To attach the ceiling mounting plate:
• To the ceiling with M8 thread bars so that they stand the weight
of the unit.
• Horizontally, because the levelness of the ceiling mounting
plate determines the levelness of the unit.
• There is a 6 mm space between the rear edge of the ceiling
mounting plate and the wall.
• The minimum distance between the bottom surface of the
ceiling mounting plate and the false ceiling is 14 mm. When this
minimum distance is used, the distance between the top of the
unit mounted on the ceiling mounting plate and the ceiling is
around 2 mm.
Insulate the outdoor air and exhaust air duct against condensation
also between the unit and the ceiling mounting plate.
Mounting the ceiling mounting plate
1. Attach the M8 thread bars to the ceiling and turn the nuts (A) to
the bars.
2. Shorten the lower ends of the thread bars so that they will be
at no more than 25mm from the lower surface of the ceiling
mounting plate. Thread bars can be shortened only before the
ceiling mounting plate is installed.
3. Lift the ceiling mounting plate in place.
4. Push a rubber damper (B) and a washer (C) onto each thread
bar, and ensure that they touch the bottom of the cups of the plate.
5. Turn the nuts to make sure that the unit is horizontally level.
Lastly, fasten the screws.
