1. SECURITY RULES
PLEASE
NOTE:
IMPORTANT
SAFETY
INSTRUCTIONS.
C
AREFULLY OBSERVE ALL THE
FOLLOWING INSTALLATION INSTRUCTIONS TO ENSURE PERSONAL SAFETY. IMPROPER
INSTALLATION CAN SERIOUSLY ENDANGER SAFETY. KEEP THESE INSTRUCTIONS AFTER
INSTALLATION.
MANDATORY RISK ANALYSIS AND PROTECTION MEASURES.
The Nekos 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
should 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.
MAINTENANCE and REPAIRS
Periodically check the installation by inspecting the cables, springs, rods and mechanical
parts for wear or damage. Do not use if repair or adjustment is required.
Disconnect the power supply during cleaning or maintenance operations.
Do not use solvents or jets of water to wash the appliance. The appliance should not be
submerged in water.
In the event of breakage or malfunction, switch the appliance off at the general switch and
call for the services of a qualified technician. Repairs should only be performed by
qualified personnel at assistance centres authorised by the manufacturer.

15
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 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 P (Kg) = Weight of the window (mobile sash only)
C (cm) = Opening stroke (actuator stroke) H (cm) = Height of the mobile sash
For horizontal light domes or
skylights
F = 0.54 x P
(Eventual weight of snow or wind on the
cupola should be calculated separately).
For vertical windows
 TOP HUNG WINDOWS, OUTWARD OPENING (A)
 BOTTOM HUNG WINDOWS (B)
F = 0.54 x P x C : H
(Eventual load of favourable or unfavourable wind
on the sash 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).
ATTENTION. For safety reasons the actuator should not be assembled if dimensions are
inferior to those indicated in the table below. In the event that the height of the sash should
be lower, call on the manufacturer to check the appliance.

Top hung windows opening outwards with horizontal assembly 400 550
Bottom hung windows (motor on frame) 400 550
Bottom hung windows (motor on sash) Consult manufacturer

3. 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 240 and 360 mm. 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 (NEKOS patent) and allows the actuator to rotate to
follow the track of the chain even on shorter windows.
4. MANUFACTURE AND APPLICABLE STANDARDS OR REGULATIONS
INTENDED USE
The chain operated series
KATO 253
actuator has been designed and
manufactured to open and close top hung windows, bottom hung windows, dormer

8. INSTRUCTIONS FOR ASSEMBLY
These indications are for specialised technical personnel and basic work and safety
techniques are not indicated.
All preparatory, assembly and electrical connection operations must be performed by specialised
technical personnel to guarantee optimal function and service of the actuator.
Check that the following fundamental conditions have been met:
Before installing the actuator, check that the moving parts of the window on which it is to
be installed are in perfect working condition and that they open and close properly and
are well balanced (where applicable).

18
Actuator specifications must be sufficient for movement of the window without
encountering any obstacle. The limits indicated in the technical data table must not be
superseded (page 16) and the most appropriate stroke should be selected. Calculations
should be checked using the formula indicated on page 15.
Attention.
Check that the electrical power supply corresponds to that indicated on the
TECHNICAL DATA label on the machine.
Ensure that the actuator has not been damaged during transport, first visually and then by
powering in both directions.
Check that the width of the inside of the window (where the actuator is to be assembled)
is over 375 mm, otherwise the actuator should not be installed.
Check that once the actuator has been installed the distance
between the fixed part of the window frame (where the actuator
is to be assembled) and the mobile part of the window frame
(where the bracket is to be fixed) is greater than or equal to 0
mm (aside figure). If this is not the case the actuator will not
function correctly as the window will not close correctly. If
required, add additional thickness below the support brackets
to reset the quota.
For bottom hung window frames injury could be caused by accidental falls of the window.
An appropriately sized flexible link arm or fall prevention safety system designed to resist
a force equal to at least three times the total weight of the window MUST be installed.
8.1. Preparation of actuator for assembly

10. PROGRAMMING THE ACTUATOR
10.1. Stroke-end at opening
At one end of the actuator is a pin which can be adjusted using a
screwdriver and an indicator arrow (see photo) to set stroke length
(240 or 360 mm).
The actuator cover has two reference marks:
 1 mark (240 mm stroke);
 2 marks (360 mm stroke).
Attention: never select 360 stroke when actuator is at 240
end stroke; inner selector can irremediably brakes.
10.2. Stroke-end at closure
The stroke-end at closure is automatic and cannot be programmed. The actuator stops when the
power encountered by the actuator when the window reaches complete closure is absorbed and
the seals are pressed right in. After each closure or intervention of electronic protection devices, the
chain will move about 1 mm in the opposite direction to give correct compression to the seals and
release the mechanical parts.
Check that hinges and support brackets are rigidly attached to the window frame and all screws
correctly fixed into position. For aluminium window frames, do not use self threading or self
perforating screws as these will tear the profile after a few manoeuvre; use metric screws with
threaded inserts (see indication on page 18).
11. CHECKING FOR CORRECT ASSEMBLY
Check that the window is perfectly closed at corners and that ther
e are no obstacles
caused by incorrect positioning during assembly.
Check that when the window frame is closed the chain terminal is at least a few millimetres
away from the actuator body. This will ensure the window is properly closed and seals are
cor
rectly compressed. In the event that this should not be the case there is no guarantee
that the window is closed correctly.
Check that hinges and support brackets are aligned to each other and tightly fixed against
the window frame with screws fixed correctly into position.
Check that the window reaches the desired position according to the stroke-end selected.
12. EMERGENCY MANOEUVRES, MAINTENANCE OR CLEANING
In the event that the window frame should require manual opening due to power failure or problem
with the mechanism or for normal maintenance or external cleaning of the window frame, the
NEKOS patent allows rapid unhooking of the chain. To perform this operation, proceed as follows:
1. Unhook the flap of the quick hook locking the chain terminal to the
bracket.
2. Hold the window in one hand and remove the pin of the chain terminal
from the two u channels on the bracket with the other. (This operation
should be performed with the window open at least 10 cm to facilitate
unhooking of the chain).
3. Manually open the window frame.
ATTENTION: DANGER – the window could fall as the sash is no
longer held in position by the chain.
4. After maintenance and/or cleaning repeat points 1 and 2 in reverse order.
