Connection to the Electric Supply
CAUTION!
It is recommended to connect the pump to the power supply through a
dedicated switch on the main electrical panel of the installation, or in proximity
of the power supply connection point.
Connections to the Inlet and Exhaust Flanges
Remove the protective caps from both flanges. Connect the system to
be evacuated to the inlet flange, using a centering ring with OR and a
locking collar.
NOTE
For guarantee reliable sealing, use an OR gasket in Perbunan or Viton.
The inlet duct is equipped with a sieve filter preventing solid
particles from entering and damaging the pump.
NOTE
When the gases to be pumped out contain dust, it is advisable to insert a dust
filter before the inlet flange.
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’s capacity, use only short, straight
piping, with a diameter not smaller than that of the inlet flange.
