1. SAFETY RULES

C
AREFULLY OBSERVE ALL THE FOLLOWING INSTALLATION INSTRUCTIONS TO ENSURE PERSONAL SAFETY
SERIOUSLY ENDANGER SAFETY
MANDATORY RISK ANALYSIS AND PROTECTION MEASURES
The VARIA SLIM electrical actuators comply with the Machinery Directive (2006/42/EC), Standard IEC 60335-2-103 (Particular requirements for drives for
gates, doors and windows) and other directives and regulations indicated in the attached Declarations of Incorporation and CE Conformity (at the end of
the manual). According to the Machinery Directive, actuators are "partly completed machinery" intended for incorporation into doors and windows. The
manufacturer/supplier of the window is required, with exclusive responsibility, to ensure the compliance of the entire system with the applicable standards
and to issue CE certification. We strongly discourage any use of the actuators other than that specified and therefore, in any case, the supplier of the
complete system retains full liability.
For systems installed at a height of less than 2.5 m above floor level or other levels accessible to users, the manufacturer/supplier of the window must
conduct risk analysis regarding potential harm (violent blows, crushing, wounds) caused to people by normal use or possible malfunction or accidental
breakage of the automated windows, and to implement suitable protective measures in view of these. Such measures include those recommended by
the specified standard:
controlling the actuators via a "deadman's button" placed near the system and within the operator's field of view, to ensure that people are out of the
-
way during operation. The button must be placed at a height of 1.5 m and operated by key if accessible to the public; or:
- use of contact safety systems (also included in the actuators) that ensure a maximum closing force of 400/150/25 N, measured in accordance with
paragraph BB.20.107.2 of IEC 60335-2-103; or:
- use of non-contact safety systems (lasers, light grids); or:
- use of fixed safety barriers that prevent access to moving parts.
Automated windows are deemed adequately protected if they:
- are installed at a height of >2.5 m; or:
- have a leading-edge opening of <200 mm and a closing speed of <15 mm/s; or:
- are part of a smoke and heat evacuation system for emergency use only.
In any case, moving parts of windows that could fall below 2.5 m following breakage of a system component need to be fixed or secured in order to
prevent them from suddenly falling or collapsing: e.g. the use of safety arms on bottom-hung windows.
The device is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lacking
experience and knowledge. Do not allow children to play with the fixed controls and keep any remote-control units out of their reach.
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. TECHNICAL INFORMATION ABOUT FUNCTION

The chain actuator opens and closes the window using a double row steel chain inside a sheath. Movement is generated using electrical energy that
powers a reduction motor controlled by a functional electrical device.
Windows can be programmed to open and the device allows chain opening at 110, 200, 300 and 400 mm for VARIA SLIM, 100, 200 and 400 mm for
VARIA SLIM SYNCRO.
When the window returns to start position, that is during closure, the stroke-end uses an electronic self-regulating process with absorption of energy
and no regulation is therefore required.
The actuator is produced by the factory with the stroke-end for return set at around +1 cm (out by 1 cm). This allows the actuator to be assembled
without electrical energy powering movement and means that the window remains closed after assembly. The joint between actuator and support
brackets is quick, requires no fixing screws (patented) and allows the actuator to rotate to follow the track of the chain even on shorter windows.

3. FORMULAS AND RECOMMENDATIONS FOR INSTALLATION

3.1. 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
(Eventual weight of snow or wind on the cupola should be
calculated separately).
.
F = 0.54 x P
.
P (Kg) = Weight of the window (mobile sash only)
H (cm) = Height of the mobile sash

▪
BOTTOM HUNG WINDOWS

should be calculated separately.)
