5.2 Location
The pump must be installed in a protected area (see paragraph 3, safety rules).
It must be fastened with support feet on horizontal surface.
Ensure there is ventilation in the room or inside the machine where the pump
has been installed. To assure a sufficient cooling, avoid to overpass 40°C of
ambient temperature.
The pump must be protected against jets or sprays of water that may penetrate
tank through the exhaust port.
Whenever the pump is installed outside, it must be protected against atmos-
pheric agents and used with an oil suitable for the ambient temperature.
Avoid warm air coming from the exhaust or the cooling fans causing discomfort
to the personnel.
It must be accessible for correct and easy maintenance, by respecting the mini-
mum distances from possible obstructions:
EM4 - EM4/B
EM8 - EM8/B
WARNING:
Do not install the pump in a dusty area or where other materials may
block or cover the cooling surfaces quickly.
5.3 Connection to the machine
The connection to the chamber to be pumped down must be carried out by means
of pipes of the same diameter as the inlet port.
Pipe weights and expansions, if any, must not rest on the pump.
It is advisable to make the final connection to the pump with flexible pipes or fittings.
It is important that all the pipes and the different fittings are tight.
Very long or small diameter pipes decrease the pump performances.
5.4 Discharge air pipe line installation
When required, it is possible to pipe the pump discharge air to other rooms, or
outside.
Use pipes with the same diameter as the tank discharge port with a maximum
length of 15 m.
For longer pipes increase pipe diameter. Pipe weights must not rest on the
pump.
In the final length use flexible pipes or pipe fittings.
WARNING:
This pipe must be descending, to avoid the condensate going back to
the tank.
