•
On a spring-closing valve there is danger of injury when the clamp
connections (43.1/43.2) are opened, as the released spring pretension will
suddenly lift the actuator. Therefore, release the spring tension before
detaching the clamp connections (43.1/43.2) 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.
•
When the valve switches, when the valve seat is being cleaned or if a seal is
defective, cleaning medium exits from the leakage outlet of the rinsing valve.
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.
