Calculation Of The Force Necessary; Pack And Tools Required For Assembling The Actuator - Comunello LIWIN L30 Serie Manual De Instrucciones

4.2 Calculation of the force necessary

The calculation is made without considering the loads due to atmospheric agents.
Key to symbols F = Force required to open in N (Newton)
P = Weight of the window (only moveable part) in kg (kilogrammes)
C = Opening travel of actuator in cm (centimetres)
H = Height of the openable part of the window in cm (centimetres)

F = [(P / 2 ) x (C/H)] x 9.8
For all the W-net systems the total push force of the syncronized actuator con be calculated by creating a sum of the
force of every single actuator and the subtracting 30% of the force remaining.

4.3 Pack and tools required for assembling the actuator

The actuator is packed individually in a cardboard box. Each pack contains: electric actuator, 110V 60Hz - 230 Vac
50 Hz or 24 Vdc, with electric supply cable, actuator support brackets, chain attachment bracket, fixing bracket for
bottom-hung window, drilling template and instruction manual. Before starting to fit the actuator, we recommend
preparing the following fitting materials, tools and equipment: metre rule or tape measure, pencil, drill/screwdriver,
set of drill bits for metal or wood, set of screw bits, electrical pliers, screwdrivers, screws and/or threaded inserts
suitable for the type of window material. AVOID using self-tapping screws and/or three-lobed screws on any metal
windows.
5. INSTALLATION
With bottom-hung windows, there is a danger of potential injury resulting from the window accidentally
falling.
It is OBLIGATORY to fit limiting arms (such as the 1276 series of Comunello Frame Division range), or an
alternative safety system, of a suitable size to prevent the window from accidentally falling down.
