Installation instructions
1.
Create a core hole in the exterior wall (max. wall thickness 480 mm) with a diameter of at least
135 mm. Watch out for any supply lines in this area!
2.
Insert the slide tube into the wall pass-through created such that the outer tube (larger diameter) is on
the inside of the wall. In order to avoid cold bridges insulate the telescopic tube with suitable insulation
material.
3.
Brick the slide tube into the core hole such that it sits flush on both sides of the wall.
4.
Fasten the protection grid on the outside of the wall with 4 screws. Take rain ingress into account when
fitting the grid.
5.
Insert the interior flap valve and fasten this likewise with 4 screws. The "Top" legend on the flap valve
must be visible from the inside.
6.
When decommissioning the unit, e.g. before the start of the winter period, seal the opening in the flap
valve with the sealing cover in order to prevent air circulation.
