NOTE When the gases to be pumped out contain large quantities of vapor, it is
advisable to include a condense separator before the inlet flange.
To make best use of the pump capacity, use only short, straight
piping, with a diameter not smaller than that of the inlet flange.
NOTE
If rigid piping is used, it is good practice to use a flexible joint in order to avoid
undue forcing of the connection on the pump.
The exhaust port must be connected to a pipe that will take away the
pumped out gases.
NOTE
Application of an oil trap filter is necessary to avoid pollution of the surrounding
atmosphere by the oil present in the exhaust port during pump operation.
CAUTION!
Never block the pump exhaust line. This would cause overpressure in the casing
with the risk of breaking the glass window of the level indicator and/or expelling
the oil seal gasket.
