2. For the remaining duct closure openings, only the protruding moulded parts (outer dimension
≙
inner dimension of
duct adapter (8)) are to be cut off. Carefully cut off the protruding moulded parts in the profile groove (white dashes)
so that the insulation can be laid flush with the direction-change adapter (3).
3. To fix the direction-change adapter (3) to the outer wall, two fixing clips (1) must be mounted to the EPP housing
using PVC screw dowels (2). The two fixing clips (1) must be attached at the top of the direction-change adapter
(3) on the side facing the outer wall. The fixing clips (1) must be placed with a distance of approx. 10 cm to the side
and approx. 2 cm at the top between the drill hole and the outer edges of the direction-change adapter (3) and
screwed to the EPP housing using PVC screw dowels (2).
Preparatory work for duct adapter installation
To fix the duct adapters (8) to the outer wall, the fixing clips (1) must be mounted to the EPP housings of the duct adapters
(8) using PVC screw dowels (2). Depending on the left or right-hand-side installation variant of the flat duct (6), the fixing
clip (1) must be mounted on the side of the duct adapter (8) facing the outer wall.
When installed, the
OBEN / TOP
embossing on the EPP housing must be positioned at the top.
1. Place the fixing clip (1) with the drill hole on the centring aid (white dashed conical dome) and screw in the PVC
screw dowel (2).
