2. The customer should provide
mounting material of a
sufficient size (screws with
diameter of 10 mm, min.
strength class 8.8).
3. Screw unit tightly to the roof
or roof socket.

2. Mark and drill 4 mounting holes and insert
dowels.
3. Lift unit and fit suitable insulation and
sound-deadening material.
4. With a free inlet, fit a protective grille (type
SG) to the unit from below as protection
against accidental contact and drawing in.
5. Position unit and screw tightly to the
roof/roof socket.
Connection to piping
1. Lay folded spiral-seams ducts flush
