Hazard Areas
Please observe the following notes:
• In the event of malfunctions, shut down the valve (disconnect from the power and air
supply) and secure it against being used.
• 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.
• During cleaning via lifting function, cleaning agents can spray out of the collecting
pan for the vacuum valve as a result of excess pressure in the container to be
cleaned, sometimes in considerable quantities. Only use the lifting function when the
container is unpressurized and the collecting pan for the vacuum valve is empty.
