4.1 Checking upon receipt
• When the goods are delivered, make sure that all parts in perfect
condition and have suffered no damage during shipping.
• Make sure the vacuum pump has its identification plate affixed on
the front cover. 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.
• Pump must be kept in a dry storage area. During storage, inlet and
outlet ports must be kept closed.
4.2 Storing in the warehouse
• If the pump will not be installed inside a short time after delivery:
- 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;
- Store in a closed and dry place. 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.
4.3 Mounting
• The mounted aspirator must be accessible for maintenance and
firmly fixed on a frame or angled base with a 3° max inclination on X
and Y axes (see Fig. 4.1). The structure must be fit to avoid flexions or
vibrations.
• Provide enough space for air ventilation and disposal of heat when
pump is running. See Fig. 4.2 and 4.3 for indication of the distance to
be respected.

• 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.
• The oil tank is mounted on the suction side of the housing. Thus,
the rotary direction determines the pump overall dimensions. See also
paragraph 2.1.
