Explanatory notes on safety information
In this Manual dangers, risks and items of safety information are highlighted to attract special attention.
Information marked with the symbol above describes practices, which if fail to comply with, can result in serious injury or
danger of death for users or third parties or in material damage to the system or the environment. It is vital to comply with
these practices and to monitor compliance.
The rest of information not specifically emphasized in this Manual, along with Data Sheet and product marking, must also be
observed and complied with for safely using the product.
3. PRESERVATION, STORAGE, HANDLING & TRANSPORT
ATTENTION!
- Protect against external force (impacts, vibrations, etc.).
- Allow only skilled personnel; suitable handling and lifting equipment must be used. See Data
Sheet for weights or consult manufacturer.
- Always use suitable protection equipment, and minimize the use of human body force at any step
to avoid injuries.
- Special arrangements must not be used to take up external forces that they are not designed for:
e.g. do not use them as climbing aids, or as connecting points for lifting gear, etc.
- There is a risk of body member (hand, finger, arm…) crushed against any other solid element
(wall, pipe, floor, etc.) during handling. Take this into account and handle with care.
- Use sling properly sized for the weight and in good condition.
- Additional means should be considered to hold the weight of the valve.
- Do not drill additional holes on the actuator to add eyelets.
- Avoid abrupt movements or pulls while lifting.
- There is a risk of body member injury in case there is any exposed moving part between
actuator and special
arrangements
. Take appropriate measures and set warning notes when required.
- Use proper packing for transportation.
- Keep storage protection before installation.
-Keep the actuators in its steady position, without energy source applied.
- In order to prevent damage, corrosion or rust on the surface, avoid extreme temperatures (keep at 5ºC to 50ºC), avoid high
environmental humidity or corrosive environment. Keep the actuators away from direct sunlight, dust, flames or rain.
- Do not leave actuators directly on the floor.
- Make sure connections are protected by plugs.
- In case of long storage, operate on complete cycle open and close every 6 months with clean air under maximum air supply
pressure.
- Do not pile up excessive weight. In case of severe bumping inspect the material for any damage and replace if necessary.
4. DESCRIPTION
