GENERAL SAFETY ADVICE

The valves described in this manual are especially designed to ensure a correct circulation of the flow in all work phases.
Device should be installed in accordance with the specific instructions for each installation. All existing safety legislation should be
respected at all times in order to avoid accidents.
Any modification to the electric actuator requires prior authorisation from the manufacturer. Spare parts and accessories authorised
by the manufacturer are a guarantee of greater safety. The manufacturer of this actuated valve is exempt from all responsibility for
damage arising from unauthorised spare parts and accessories.
The electrical parts of this device will have an electrical current running through them during operation. All work on the automatic
valve and other related equipment should only be carried out after having first disconnected the start up mechanism.
The user should ensure that all assembly and maintenance work is carried out by suitably authorised, qualified personnel, and that
they have previously read the installation and service instructions set out in this manual.
Safe usage of this actuated valve can only be guaranteed by closely following the installation and service instructions set out here.
Voltage should not be exceeded under any circumstances.
In case of malfunction or breakdown, contact the nearest factory representative or technical assistance service department. Knocks
should be avoided during transport, since they may damage the body and mechanism of the valve.
Store the valve in the original packaging, protected against humidity, environmental damages and direct sunlight.
ELECTRIC BUTTERFLY VALVE WARNINGS
The maximum service life of the valve is specified in EN ISO 16136. This has been verified at the factory using ageing tests specified
in the standard.
Correct installation and handling of the valve, as well as adherence to the maximum pressure and temperature conditions specified
in this manual are essential in order to preserve the service life of the valve.
The liquid to be conducted must be compatible with the valve materials. Consult chemical resistance charts published by Cepex or
ask to the Cepex technical department.
The use of tools to open or close the manual valve control is not recommended.
Before carrying out any maintenance operations on the pipe or valve, ensure that the system has been depressurised by releasing
the pressure and emptying the pipes, following the specific safety regulations for each product.
Before installation, check that the valve is undamaged and that it contains all the parts required for installation.
After long periods of inactivity, check the grease on the o-rings and follow the maintenance instructions set out in this manual. The
grease must be compatible with the valve materials.
Rapid closure of valves should be avoided to eliminate the possibility of water hammer causing damage to the system.
When using the valve as the final element of an installation, the risks of the liquid should be taken into account and the pressure
and temperature should be controlled, according to the safety standards for each product.
Make all connections following the instructions referring to electrical supply set out in this manual. Ensure that all cables are correctly
connected.
If the box at the end of the run needs to be opened, disconnect all electrical supply before opening it; when it is closed again, check
that it is correctly positioned to avoid any contact with water. Also check that connectors are correctly positioned.
At all times, avoid contact, even accidental, with the motorised valve's moving parts during operation and/or before it has come to
a complete standstill.
Ensure that the start-up mechanisms are blocked before beginning any electrical maintenance. The following steps should be
followed before any modification to the motorised valve:
1.- Disconnect from the main supply.
2.- Block the system's start-up mechanisms.
3.- Make sure that no voltage is running through the circuits, including the auxiliary circuits and supplementary services.
All the above should be taken as indicative and not directly linked to the safety procedure as specific safety regulations may be in
place in some cases.
IMPORTANT: As a result of the complexity of the subject, the installation, usage and maintenance instructions found in this manual
are not designed to cover all imaginable service and maintenance scenarios. Should any further instructions be required or specific
problems encountered, please do not hesitate to contact the distributor or valve manufacturer.
In case of non correct working, check the Troubleshooting table (T13).
