CAREFULLY OBSERVE THE FOLLOWING RULES
•
When transporting the pump, use proper slinging. Store the pump in stable places.
•
Installation and maintenance must be operated only by qualified personnel wearing the proper clothes
and the necessary tools as well as protection devices.
•
Before each maintenance operation:
•
Stop the pump and restore the atmospheric pressure.
•
Disengage the drive system.
•
Only operate after the pump has cooled down.
•
When the pump is running, some parts may reach very high temperatures (above 100°C). Use all
necessary precautions to avoid contact.
•
Operators
working
nearby
must avoid prolonged exposure to the noise emitted by the aspirator, if not
equipped with the proper ear-protection devices.
•
Avoid accidental suction of solids: solids may be projected at high speed through the exhaust manifold
and cause injures.
