•
On a spring-closing valve there is danger of injury when the clamp connection
(43, 46) is opened, as the released spring pretension will suddenly lift the
actuator. Therefore, release the spring tension before detaching the clamp
connection (43, 46) by supplying the actuator (A) with compressed air.
•
Before starting any service, maintenance 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 have very sharp edges. When transporting and
assembling the valve be sure to wear suitable protective gloves.
