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.
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

25
ENGLISH
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 with “biased-off switch” mode. 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 capabilities 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.

4.1 Types of power supply
The Liwin series of actuators is available in various models and colours in two electrical supply versions:
• 230 Vac - can be supplied with mains power 230 Vac (50 Hz) (with a tolerance of ±10%), with a three-core supply
cable: BLUE, neutral common; BLACK, open phase; BROWN, closed phase.
• 24 Vdc - can be supplied with a voltage of 24 Vdc with a two-core supply cable: BLUE, connected to the +
(positive) closed; BROWN, connected to the + (positive) open.
4.2 Calculation of the force necessary
The calculation is made without considering the loads due to atmospheric agents.
Key to symbols F = Force required to open in N (Newton)
P = Weight of the window (only moveable part) in kg (kilogrammes)
C = Opening travel of actuator in cm (centimetres)
H = Height of the openable part of the window in cm (centimetres)

F = [(P / 2 ) x (C/H)] x 9.8 F = [(P / 2 ) x (C/H)] x 9.8 F = (P / 2) x 9.8
For all the W-net systems the total push force of the syncronized actuator con be calculated by creating a sum of the
force of every single actuator and the subtracting 30% of the force remaining.
4.3 Pack and tools required for assembling the actuator
The actuator is packed individually in a cardboard box. Each pack contains: electric actuator, 230 Vac 50 Hz or 24
Vdc, with electric supply cable, support brackets, fixing bracket for top-hung window, fixing bracket for bottom-hung
window, drilling template and instruction manual. Before starting to fit the actuator, we recommend preparing the
following fitting materials, tools and equipment: Metre rule or tape measure, pencil, drill/screwdriver, set of drill
bits for metal or wood, set of screw bits, electrical pliers, screwdrivers, screws and/or threaded inserts suitable for
the type of window material. AVOID using self-tapping screws and/or three-lobed screws on any metal windows.

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.
6.1 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.
