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
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).

TTENTION
.
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.

3. TECHNICAL INFORMATION ABOUT FUNCTION
The chain operated actuator opens and closes windows by means of a steel chain
located inside the cover. Movement is powered by electricity which powers a gear
motor controlled by an electronic function device. Window opening can be programmed
to open at 110, 200, 300 and 400 mm
(see respective chapter)
.
During closure the end course uses a self-regulating electronic process with power
absorption and therefore requires no regulation.
The actuator leaves the factory with factory settings of +1 cm for the return course
which allows the actuator to be assembled without electricity, with the window in closed
position after assembly is complete.
4. MANUFACTURE AND REFERENCE STANDARDS
INTENDED USE.
The KATO ADV RADIO chain actuator is designed and built
to open and close awning and bottom-hung windows, dormer windows, domes
and skylights used for ventilation and climate control in rooms; any other use is
strongly discouraged, with the supplier of the entire system in any case
retaining sole liability. It can also be used in combination with the
NRS1
operated rain sensors.
The actuator is manufactured in accordance with the Directives and following
Regulations listed in the attached Declaration of Incorporation and Conformity
.
Electrical connections must conform to regulations in force for the design and
set up of electrical equipment.
To ensure efficient separation from the grid, an approved type of bipolar “dead-
man” switch should be used. An omnipolar general power switch with minimum
distance of 3 mm between contacts should be installed upstream of the control
line.
The KATO ADV RADIO actuator is packed in one single carton.
Each package contains:
Actuator with 2 metre (±5%) lead.
Standard support brackets with distancer (A).
Bracket for vertical assembly of the actuator (B).
Bracket for transom window (C).
Bracket for outward opening fixture (D).
Template for boring.
Instruction manual.
5. LABEL DATA AND MARKINGS
The KATO ADV RADIO actuators have CE marking and comply with the Standards
listed in the Declaration of Conformity. They also come with a Declaration of
Incorporation, due to their classification by the Machinery Directive as “partly completed
machines”. Both declarations are included in the final pages of this manual.
