INSTALLATION DIAGRAM
Notes
−
If total wall thickness is greater than 22cm, it can be considered to install the duct without
cowling.
−
For retrofit projects we recommend to use always the cowling to allow a correct installation
of the trade seal.

The ‘Wall Mounting Bracket’ and the REC
-
Duo ‘Power Supply Plate’ should be at l
east fixed
with 2 screws to the timber/ steel frame.
