CAREFULLY OBSERVE TH
E 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 pres
sure.
• 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 injure
s.
