WARNING Falling objects: Risk of injury
to persons below the installation site if the ex-
ternal cover or objects fall down during instal-
lation work or if the external cover comes loo-
se due to improper fastening.
Ensure that nobody is below the installation site.
Fasten the external cover properly using the en-
closed mounting material (screws), secure it
against falling and seal it to the external plaster
using suitable sealing material. Sealing material
is to be provided by the customer.
NOTICE Building and moisture damage if the
condensate drainage channel of the mounting
sleeve is dirty/blocked or if the drip rail is in-

ting sleeve so that the condensate can drain sa-
fely into the external cover.
