Attention: carefully apply these prescriptions.
3.1.
General recommendations
• Installation and maintenance must be carried out with the unit
totally disengaged from its drive system and must be performed by
qualified personnel.
• Use adequate clothing (avoid ties, loose sleeves, necklaces and
so on) and suitable protection equipments (gloves, protection glasses,
boots...).
• When transporting the pump, use proper slinging. Store the pump
in stable places.
• Make sure that all the parts of the unit are idle and cool, before
performing any maintenance operation.
• Before each maintenance operation, stop the pump and restore
the atmospheric pressure.
• 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.
• Do not start the machine if the protection devices provided for
transmissions are removed. Replace damaged parts.
• Pressure relief valve: point the air flux away from the operators.
• Do not use the aspirator over its designed limits: the machine may
be damage and the operator may be injured.
Do not exceed the power supply parameters
indicated in the technical tables (see par. 2.3).
3.2.
Intended use
• The vacuum pump PN130, PN140 and PN155 are designed to
convey filtered air into systems for the vacuum production or for the
suction of powders or liquid wastes. Any other usage shall be
considered improper.
• Do not sack toxic substances and inflammable or explosive
gasses, since the internal components of the pump may reach high
temperatures.
• Liquids or solids infiltrations can seriously damage the pump.
• Do not run the pump over its designed operating limits (see par.
2.3): it may break and transmission can be damaged.
