Formulas and recommendations for installation

2.1. Calculation of opening / closure force

Using the formulas on this page, 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 in accordance with sash height

The actuator stroke should be selected in accordance with the height of the sash and
its application. Make sure that the actuator does not touch the profile of the sash when
moving along its track, and ensure there are no obstacles blocking the opening and that
the rack moves smoothly along the window frame.
A . For safety reasons, always check application before fixing the actuator to

the frame or sash. In the event of difficulty, request assistance from the manufacturer to
check application.
P (Kg) = Weight of the window (mobile sash only)
H (cm) = Height of the mobile sash
For vertical windows
