10.2. Calculation of the number of push / retention points
If the window has a width exceeding 120 cm, it is advisable to use several push / retention
points by assembling several actuators. The simple formula below allows you to calculate
the position of these points.
Formula:
The two side dimensions
-
LA : (PA x 2) = QL
The central dimensions
-
QL x 2
Legend:
LA
= Window Sash Width (hinges side)
PA
= Actuator Attachment Points
QL
= Side Dimensions

10.3. Assembly with outward opening window
A. Mark the centre line of the frame in pencil on both moveable and fixed parts (Fig. 1).
When more than one actuator is installed on the same window, mark as indicated in §
10.2 above.
B.
Place the motor support bracket along the edge of the fixed part of the frame in line
with the centre line marked out previously and mark the positions for the four holes
for the fixing screws
(Fig. 2).
C. Drill holes into the frame and screw in the motor support bracket, making sure that all
screws are fitted tightly (Fig. 3 and Fig. 3bis).
D. Line up the front bracket along the centre line on the moveable part of the frame and
mark out the holes required for the screws (Fig. 4).
E.
Drill the holes and screw in the front bracket, making sure that all screws are fitted
tightly
(Fig.5 and Fig. 5bis).
F. Take the clamp screws and connect them to the motor support bracket. Leave them
slack by at least two turns.
G.
Insert the dove-tailed section of the actuator into the clamp screws. Make sure the
shaped part of the base fits neatly into the slot to ensure the actuator runs smoothly
along its axis
(Fig. 6).
H.
Now position the actuator so the eyebolt head is inserted into the front bracket
support. Insert the M6x25 screw into the bracket and into the eyebolt and tighten the
self-locking bolt with two 10 spanners.

I. Manually move the actuator along its axis to close the frame and make it weather
tight. Tighten the clamp screws previously only placed and set the actuator in line
with the frame. Suggested tightening torque is 4-5 Nm.
J.
Plug the actuator in and carry out a test to check opening and closure of the frame.
Make sure the frame closes fully and is weather tight.
K.
The limit switch for the actuator is automatic on re-entry. The equipment will exert a
pressure to guarantee even the largest of frames is completely weather tight.
10.4. Installation on domed rooflights, dormers or industrial skylights
To install the actuator on these types of windows, follow the instructions for “Installation on
awning windows” given in § 10.3 above.
10.5. Assembly with opening inwards
A.
Mark the centre line of the frame in pencil on both moveable and fixed parts
(Fig.1).
When more than one actuator is installed on the same window, mark as indicated in § 10.2
above.
B.
Place the motor support bracket along the edge of the moveable part of the frame in
line with the centre line marked out previously and mark the positions for the four
holes for the fixing screws
(Fig. 2).
C.
Drill holes into the frame and screw in the motor support bracket, making sure that
all screws are fitted tightly
(Fig. 3 and Fig. 3bis).
D.
Line up the front bracket along the centre line on the fixed part of the frame and
mark out the holes required for the screws
(Fig. 4).
E.
Drill the holes and screw in the front bracket, making sure that all screws are fitted
tightly
(Fig. 5 and Fig. 5bis).
F.
Take the clamp screws and connect them to the motor support bracket. Leave them
slack by at least two turns.
G. Insert the dove-tailed section of the actuator into the clamp screws. Make sure the
shaped part of the base fits neatly into the slot to ensure the actuator runs smoothly
along its axis
(Fig. 6).
H. Now position the actuator so the eyebolt head is inserted into the front bracket
support. Insert the M6x25 screw into the bracket and into the eyebolt and tighten the
self-locking bolt with two 10 spanners.
I. Manually move the actuator along its axis to close the frame and make it weather
tight. Tighten the clamp screws previously only placed and set the actuator in line
with the frame. Suggested tightening torque is 4-5 Nm.
J. Perform a complete opening and closing test on the window. When the closing
operation is completed, ensure that the window is properly closed by checking the
compression of the seals.
K. The stroke-end of the actuator during return is automatic. The device exerts traction to
ensure perfect compression of the seals.
