Mounting the ventilation unit to the ceiling
The model MyVallox 119 CFi can be equipped with an optional ceiling mounting plate. To attach the ceiling mounting plate:
- Install the ceiling mounting plate with M8 thread bars so that it is horizontally level. Do not fasten the ceiling mounting plate too tight to the ceiling.Note:The end of the thread bars must be 5 mm or less below the fastening nut.
Alternative 1.
Pull from the operating levers (A) to ensure that the sliding bars move and restore to their original position.
Alternative 2.
Make sure that the sliding bars move and that they return to their original position by pushing the ejector lever (B) e.g. with a small screwdriver.
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 25 mm below the top of the white covering strip.
- Ensure that the insulation washers are in place in the outlet collars below the ceiling mounting plate.
- Remove the door covering strip and the door of the ceiling mounting plate during the installation of the MyVallox 119 CFi unit.
- Lift the ventilation unit close to the ceiling mounting plate and feed the cables through the hole in the ceiling mounting plate on top of the ceiling.Note:Remember to make a maintenance hatch in the finished ceiling, so that the cables can be accessed. The distance between the maintenance hatch and the ceiling mounting plate should be around 500 mm.
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 to the grooves on the side panels of the ventilation unit (C).
Alternative 1.
The front bottom corners of the ceiling mounting plate have operating levers (A) that lock the plate. If the inner edges of the levers have returned to the same level as the front edge of the unit’s ceiling, the unit has been locked onto the ceiling mounting plate.
Alternative 2.
The front edge corners of the ceiling mounting plate have holes through which you can see the ejector levers (B) of the locking mechanism. If the inner edges of the levers have returned to the same level as the interior surface of the covering strip, the unit has been locked onto the ceiling mounting plate.
- Alternative 1.
Where required, the unit can be detached from the ceiling mounting plate. 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.
Alternative 2.
Where required, the unit can be detached from the ceiling mounting plate. Lift the unit slightly upwards and push (e.g. with a small screwdriver) both ejector levers (B) of the ceiling mounting plate simultaneously to detach the unit from the ceiling mounting plate.
Attic floor feedthrough 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 attic floor penetration plate can be fastened on the finished rear door. The minimum distance of the attic floor penetration plate from the finished side walls is 15 mm.
