4.2.7 Installing the exterior wall hood
For the installation of the exterior wall hood, one needs to make sure that a temporary support is used to prevent
it from dropping down! Supplied installation accessories must, if necessary, be supplemented on-site with
appropriately suitable mounting material depending on the design of the outside wall surface. The responsibility
for professional, safe installation lies with the technical crew!
The exterior wall hood should not be installed until the outside wall surface is completed; however, immediately
following installation of the ventilation unit! Check the flatness between the wall mounting pipe, the EPP pipe
housing, and the outside wall surface!
Proceed as follows for the installation of the exterior wall hood:
1. Remove the front cover from the exterior wall hood.
