Then make two Ø4.5 holes on the sash for the attachment bracket. The
measurements are specified in the diagram below.

Surface mounting on top-hung windows opening outwards or
bottom-hung windows
The actuator can also be surface mounted on top-hung windows opening
outwards or dormer windows and on bottom-hung windows, however for these
specific applications special support brackets are required for the actuator which
must be supplied separately.
The two half-brackets attaching the actuator to the sash, however, are the same
standard brackets supplied with the actuator and included in the package.
To prepare the holes on the window frame and sash, use the drilling template
included in the package of the special brackets; this template also specifies the
diameter of the holes and their position in reference to the inner edge of the
window frame.
Warning. In order to prevent unpleasant mishaps with the machine and
possible safety hazards, carefully choose the length of the clamping screws
in order to avoid damaging the power supply cables during the mounting
procedure.
In order to carry out a cost-effective and precise up-to-standard work, it is best if you
prepare the following complementary material: small parts, equipment and tools.
Fastening on metal window frames: M4 threaded inserts
(2 pieces for recessed
mounting and 4 pieces for surface mounting)
, M4x12 flat head metric screws
(2
pieces (4 pieces for surface mounting))
.
Fastening on wooden window frames: Ø4 self-threading wood screws
(2 pieces
for recessed mounting and 4 pieces for surface mounting)
, with an appropriate
length for the type of window frame.
