Installation

Ceiling installation

Ensure the ceiling is capable of
supporting the weight of the ALF100SM,
especially if this is a metal frame (MF)
ceiling structure.

As with wall installation, the ALF100SM
can be installed between any set of
rafters. If necessary, pack the bay to
create an opening of 380mm (15”), then
follow the instructions in the previous
section to screw the long sides of the
cabinet in place.
