SHUT DOWN PROCEDURE

1.

Close the system inlet isolation valve.

2.

Switch control power to OFF.

3

Open the gas ballast valves to vent the

pump  to  atmosphere.  If  system  is
equipped  with  an  automatic  vent  valve  or
an  anti-suckback  valve,  no  action  is

needed. Failure to vent the pump to
atmosphere may cause oil to fill into the

pumping chamber and travel back through
the inlet manifold into the vacuum process
chamber.

4

If water cooled, turn off the cooling water
supply.
