3.3 Connection to system
Inlet connection
The inlet flange can be connected with a vacuum-tight flexible hose and/or pipe.
The pipes should cause no stresses on the pump’s flanges. If necessary, com-
pensators must be installed.
Avoid restriction of the pipes in order not to decrease the pumping speed of the
pump. The nominal diameter of the pipes has to be least the same as the diame-
ter of pump’s inlet flange.
Liquid and solid particles must not enter the pump. Install the adequate filters,
separators and/or condensers. In case of doubt consult Leybold.
The intake line of the pump must never be connected to a device with over at-
mospheric pressure.
Connection to exhaust side
No isolation or restricting devices should be installed in the exhaust line of the
pump.
If an exhaust line is installed, it must at least have the same diameter as the ex-
haust flange. It should be installed in a manner so that no condensate can enter
the pump (siphon, slope).
The maximum exhaust pressure must neither exceed 1.15 bar absolute (0.15
bar relative), nor fall under atmosphere pressure minus 15 mbar corresponding
pressure regulating devices to be installed by the user.
A pump exhaust to be connected if oil mist or process gases are to be avoided
in the pump area.
3.4 Oil filling
The necessary oil is supplied in a can beside the pump. To fill in the oil, unscrew
the oil fill plug and fill in until the oil level reaches the MAX–mark beside the oil
sight glass.
Operating of the pump without oil or operating with incorrect direction of rotation
can destroy the pump.
