•
Never reach into the lantern (9) when the valve is switching. Fingers can be
crushed or cut off.
•
On a spring-closing valve, there is a risk of injury upon releasing the clamp
connections (43) as the released spring pretension will suddenly lift the
actuator (A). Before releasing the clamp connection (43) therefore relieve the
spring tension by pressurizing the actuator with compressed air.
•
Before starting any maintenance, servicing or repair work, disconnect the
valve from the power supply and secure it against inadvertently being
switched back on again.
•
Only allow a qualified electrician to carry out any work on the electrical power
supply.
•
Check the electrical equipment of the valve at regular intervals. Immediately
remedy loose connections and molten cables.
•
If work on live parts cannot be avoided, call in a second person, who can
operate the main switch in case of an emergency.
•
The housing sockets (406) have very sharp edges. When transporting and
installing the valve be sure to wear suitable protective gloves.
•
When the valve switches, when the valve seat is being cleaned or if a seal is
defective, medium (product cleaning medium) exits from the leakage outlet
(15). Collect this liquid in a suitable container such as a funnel or a drip pan
and discharge it in a safe manner. Observe the instructions in the safety data
sheets issued by the cleaning agent manufacturers.
