f) Apply the brackets (A) to the window frame using flat head screws as indicated above. Check
both horizontal and vertical alignment of brackets.
g) Assemble the bracket for bottom hung windows onto the mobile part of the window frame using
the reference points indicated on the template.
h) Complete assembly between chain terminal and quick hook using the Ø4x32 pin provided and
insert into central position (Fig.11).
i) Hook the actuator onto the brackets inserting the two channels at the end of the actuator into the
pins provided.
j) Rotate the actuator 90°, bring the chain terminal up to the hinge and insert the pin into the
channel of the latter. Connect the quick hook onto the rod.
k) Perform the electrical connections according to the diagram below or the label on the feeder
cable.
l) Check that the output of the chain is perfectly aligned with the bracket. In the event that this
should not be the case, loosen the fixing screws and reposition the bracket correctly.
m) Perform a complete test of opening and closing of the window frame. After closure, check that
the window frame is completely closed and check pressure against the seals.
n) The stroke-end of the actuator during return is automatic. The appliance exerts traction to
guarantee perfect pressure against the seals.
9. ELECTRICAL CONNECTIONS
Machines have been equipped with a power connection cable which complies with safety
regulations and protection against radio disturbance. Before performing the electrical connection
consult the table below and check correspondence between the feeder cable and the tension data
on the actuator label.

If feeder cables require extending to the control button for low voltage actuators (24V
), cable
sections should be selected accordingly. Conductor sections are indicated in the table on page 17

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 there 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
correctly 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.

DANGER
– the window could fall as the sash is no
longer held in position by the chain
