Compulsory accessories
• Compulsory accessories for a correct running of the pump:
Safety filter mounted between the pump and the secondary
shutoff.
Over-pressure safety relief valve.
4.2.
Checking upon receipt
• When the goods are delivered, make sure that all parts listed on
the delivery note are in perfect condition and have suffered no damage
during shipping.
• Remove the parts of the packaging that can be dangerous if
sucked by the compressor.
• Make sure the vacuum pump has its identification plate. Pumps
without such identification are to be considered anonymous and
potentially dangerous: in such an event, they must not be used,
otherwise the manufacturer will be deemed free from any liability
whatsoever.
4.3.
Storing in the warehouse
• If the pump will not be installed inside a short time after delivery:
Store in a closed and dry place.
Remove the guards from the ports and spray a film of
protective oil over the inner surfaces of the body, rotors and
sides. Then attach again the guards.
Renew the preserving oil periodically.
• To temporarily store a used pump, follow the instructions below:
Thoroughly clean the pump.
Equip the pump with suitable anti-corrosion protection.
4.4.
Handling and installation
• Before each movement, verify that the lifting equipment has a
suitable capacity (check the weight of the pump, possibly showed in
this manual, in the paragraph 2.2).
• Do not lift the packaging or the machine when moving more than
50 cm from the ground. Proceed with the final lifting only near the
installation point.
• Harness the machine with suitable straps / chains near the main
body, paying attention to the position of the mass centre of gravity to
ensure the load stability.
Warning: do not stand under the machine when it
is lifted during the installation.
4.5.
Mounting
• The pump must be assembled for an easy access for maintenance
operations and secured rigidly to a frame or levelled base (max. 3°
slant to the horizontal plane. See Fig. 4.1). The base must be such as
to avoid vibrations, bending or deformation.
• It is recommended to install the pump on vibration adsorbing pads
to reduce the noise and vibrations produced during its operation.
• Leave enough space around the pump to allow the free circulation
of air for cooling; avoid exposure to dirt and debris.
• Provide the necessary space to reach all points of lubrication
control (oil level), and the oil tank filler cap, the lever of the 4-way
switch, vanes inspection ports. See Pic. 4.1.
• The oil tank is mounted on the rear side of the pump. Instead for
PN 106 the oil tank is mounted on the suction side of the housing.
• Provide for suitable manoeuvring spaces of the inverter lever. The
control lever has two possible switching positions well defined by the
latches and numbers reported on the fusion. It is directly connected to
the internal diverter tang of the inverter, making it very intuitive: 90° of
the lever switching corresponds to 90° of the inverter switching.
• Based on the functionality of the system which will house the
decompressor, the designer of the end machine, must:
Properly signal the functionality of the inverter according to the
position of the manual operating lever or of the pneumatic
actuator or of the hydraulic one.
Install suitable pressure and / or vacuum restrainer valves near
the inlet and outlet points of the machine.
• In the event that the pump is electrically isolated, connect it to the
ground or make it equipotential with the housing machine. Check that
the paint does not prevent its passage.
