The actuator is destined exclusively for installation indoors. For any
special application we recommend you consult the manufacturer
beforehand.
After removing packaging, check for any damage on the appliance.
Always request exclusive use of original spare parts. Failure to respect
this condition could compromise safety and invalidate the benefits
contained in the warranty for the appliance.
In the event of any problems or queries, consult your agent or contact the
manufacturer directly.

2. Formulas and recommendations for installation

2.1. Calculation of opening / closure force

Using the formulas below, approximate calculations can be made for the force
required to open or close the window considering all the factors that determine
the calculation.
Symbols used for the calculation
F (Kg) = Force for opening or closing
C (cm) = Opening stroke (actuator stroke)
For horizontal light domes or
skylights
F = 0.54 x P
(Eventual weight of snow or wind on the
cupola should be calculated separately).
2.2. Maximum opening according to height of sash
The actuator stroke is in accordance with the height of the sash and its
application. Check that the actuator stroke does not touch the profile of the sash
and that the chain does not exert force on the window frame (measurements in
mm).
P (Kg) = Weight of the window (mobile sash only)
H (cm) = Height of the mobile sash
For vertical windows
▪
TOP HUNG WINDOWS
▪
BOTTOM HUNG WINDOWS
F = 0.54 x P x C : H
(Eventual load of favourable or unfavourable
wind on the sash
separately.)
