Installation
Critical dimensions for a retrofit
installation
Each building and location may require a
slightly different approach to preparing
the opening for an ALF100SM and
making good the wall afterwards. Use
these general instructions as guidance
for a retro-fit installation of the ALF100SM
into an existing cavity wall.
NOTE: The ALF100SM is not suitable for
retrofit into walls of solid construction.
• Locate the studs either side of the
area where the ALF100SM will be
mounted.
• Remove any skirting that passes
across the mounting area.
• Remove all plasterboard from
between the studs and a further 5mm
(
3
/
16
”) each side to a width of 410mm
(16
1
/
8
”) to provide a seat for the
ALF100SM front panel.
• Check that the cavity dimensions
meet the requirements below. The
width between the studs must be as
shown to provide a mounting surface
for the ALF100SM.
If your inter-stud width is greater than
380mm (15”), pack the studwork with
additional timber lengths to narrow the
opening to 380mm (15”).
