The partition between the outdoor air and exhaust air guide should be in a horizontal position and also match up
with the partition of the EPP pipe housing!
4. Determine a suitable fastening method for the four attachment points, in accordance with the outside wall surface.
5. Stick the self-adhesive, swelling sealing tape supplied with the installation kit onto the contour of the airflow features on the
back, as shown below.
6. Install the back cover of the exterior wall hood onto the outside wall surface.
When attaching the back cover, the cover must not bend! If necessary, loosen the screws so that the back cover is
still installed tightly to the outside wall surface, but does not cause any deformation.
To protect against penetrating water, the gap between the back cover and barrel end should be sealed using a
suitable sealant (weatherproof acrylic)!
7. Assemble the front cover to the back cover using four screws from the supplied installation kit.
