1.1 Introduction to this manual
Please read carefully and follow the instructions detailed in this manual. Keep the manual for use and future
maintenance. Pay attention to the configuration of the DIP-switches, to the data concerning the performance (see
“Technical Data”) and to the installation instructions. Improper use or incorrect operation, fitting or assembly can
damage the system as well as cause injury to people and damage to property.
The assembling instructions are available on the official web site
http://www.comunello.com/mowin
2. SAFETY
This installation manual is written exclusively for competent professional personnel.
The installation, electrical connections and adjustments must be carried out conforming to good practice and
according to the regulations in force. Incorrect installation can cause a potential hazard. The packing materials
(plastic, polystyrene, etc.) must not be allowed to pollute the environment, but must be disposed of correctly, and
must not be left within the reach of children since they can cause possible hazards. Before starting installation,
check the product is complete and undamaged.
If the power cable is damaged, it must be replaced by the manufacturer or his technical support or a similarly
qualified person in order to avoid any risks.
Do not install the product in an explosive environment or atmosphere: the presence of flammable gas or fumes
is a serious health and safety hazard.
Before installing the drive mechanism, put in place all the structural modifications relating to safety measures
and to the protection or segregation of all the zones involving hazards of crushing, shearing, entrapment and of
general hazard. Check that all the existing structure has the necessary requirements of strength and stability. The
manufacturer of the drive mechanism is not responsible for failing to conform to good practice in the construction
of the windows to be opened, as well as any distortion which could occur during use.
Put up the notices laid down by current regulations to identify hazardous areas.
Ensure that the electrical supply is not a temporary one, but has the required electrical boxes, and in case of
doubt or lack of (definite) information, also install:
- suitable isolating transformers;
- thermal magnetic cut-outs suitable to voltage requirements;
- surge arrester.
Before connecting the electrical supply, ensure that the electrical rating correspond to that of electrical
distribution supply. Fit onto the supply network an allpole switch with a contact gap of at least 3 mm.
1. GENERAL INFORMATION

4
Check that on the supply side of the electrical plant there is a suitable differential residual current circuit breaker
and overload protection.
When required to do so, connect to an efficient earthing/ground system fitted according to the safety regulations
in force in the country where the actuator is being installed. Before carrying out any operation (installation,
maintenance or repair), isolate the electrical supply before working on the equipment. To ensure complete
isolation from the supply current, installation is recommended of a double-pole switch of the approved type. The
low-voltage 24 Vdc actuators must be supplied by suitable power supplies (NOT TRANSFORMERS) of an approved
Class II type (double safety insulation) having an output voltage of 24 Vdc -15% to +20% (or from 20.4 Vdc min. to
28.8 Vdc max.) When using the 24 Vdc version, the cable must have a suitable cross-section, calculated based on
the distance between the power supply and the actuator, so as not to have a voltage drop or loss.
The device is not intended to be used by people (including children) whose physical, sensory or mental capabili-
ties are reduced or by people who lack in experience or knowledge, unless a person responsible for their safety
can control them or give them instructions concerning the use of the device. Children must be supervised to
ensure that they do not play with the device.
The Liwin chain actuator is intended only and exclusively for use for which it was designed, and the manufacturer
cannot be held responsible for damage due to its improper use. The actuator is intended exclusively for internal
installation to open top-hung and bottom-hung windows, skylights, dormer windows and roof windows. Any other
use is not recommended unless with the prior approval of the manufacturer. Install the actuator according to the
instructions shown in this manual.
Any apparatus serving and controlling the actuator must be produced according to the regulations in force and
respect the relevant standards issued by the European Community.
If the actuator is installed on a window at a height of less than 2.5 m from the floor and in buildings (public and
otherwise) in which the use of destination is not clear, it must be operated exclusively by a command which is not
accessible by public (key button).
The command button has to:
1) be placed at a height of 1500 mm from the floor
2) be positioned so that, at its activation, a person who carries the opening and closing has within its field of view
all the moving parts.
Do not wash the apparatus with solvents or jets of water. Do not immerse the apparatus in water.
Any repair must be carried out by qualified personnel (the manufacturer or an authorised service centre).
Always insist that only original spare parts are used.
Failure to use the original spare parts could compromise the correct operation of the product and the safety of
people or property, also annulling the effects of the guarantee enclosed with the apparatus.
In case of any problems or doubt, contact the point of sale where the product was purchased or the manufacturer
directly.

ENGLISH
With bottom-hung windows, there is a danger of potential injury resulting from the window
accidentally falling.
It is OBLIGATORY to fit limiting arms (of the Series 1276 type), or an alternative safety system, of a
suitable size to prevent the window from accidentally falling down.
5.1 Installation sequence
- Check that the width of the window, where the actuator is due to be fitted, is more than 420 mm. Otherwise,
it is NOT POSSIBLE to fit the actuator.
- Check that the force required to open/close it (calculated according to the table under Point 4.2) is less
than or equal to that shown in the TECHNICAL DATA table.
- Try manually the window opening, checking for and if necessary eliminating any sticking points that could
cause a malfunction.
- Manually test the maximum opening of the window, checking that it is greater than the travel set by the
actuator.

5.3 Operating test
Press the control button and close the window, checking that:
A. The window is completely closed. If it is not, check that the gap between the window and the frame is bigger
than or equal to 0 mm. If necessary, insert spacers so as to obtain the correct gap.
B. The chain is perfectly vertical to the window frame. If necessary adjust the fixing bracket by using the
screws and slots.
Having reached the correct closing position, press the control button and open the window in order to check
that the actuator runs freely over the full travel set up.
Having achieved the required opening run, press the control button again to close the window. Once the window
has completely closed, check that the screws, supports and fixings are tightened correctly, and that the seals
are sufficiently compressed.
