NOTICE!
Risk of water damage from incorrect
assembly!
If units with an intermediate frame are installed
outdoors, missing cover strips or incorrect
assembly may lead to the ingress of water.
To prevent the ingress of water into the inter-
mediate frame and hence into the unit, seal the
intermediate frame with cover strips.
Fix the cover strips immediately after the
assembly steps described above. If you do not
fix the cover strips immediately, water may get
into the unit and damage the components.
Each cover strip carries a code indicating its posi-
tion (see table).

Use pan head screws to attach the cover strips to
the intermediate frame.
Important:
Fix the cover strips in such a way that
the drip edge is at the bottom. Ensure that the drip
edge faces outwards.

This will prevent water from getting into out-
door units with an intermediate frame.

1.
Ensure precise fit and avoid distortion when you
connect the ducts.
Note:
Any load on the noise insulating connector
may impair the tight fit. Connect the duct in such a
way that no loads are imposed on the connector; if
necessary, slightly re-tighten the screws on the
connector.
2.
Insulate ducts (including flexible connectors and
connecting frames).
