VENT DEVICE INSTALLATION
The vent device mod. 969-9831 allows to avoid
undesired venting of the pump during a temporary
power failure (adjustable time up to 36 min.), and
enables an automatic vent operation.
Unscrew and remove the threaded plug.
Screw the flange mod. 969-9109 on the pump, tak-
ing care of the o-ring right position.
Assemble the seal ring and lock the vent device in
position using the KF klamp.
VIBRATION ISOLATOR INSTALLATION
Two vibration isolators for ISO and CFF inlet flange
version pumps are available as accessories.
The two model part numbers are the following:
− model 969-9342 for ISO 100 flange;
− model 969-9332 for CFF 6" flange.
They typically reduce the vibration transmitted from
the Turbo-V300SF pump to the system by a factor
of 20.
Please refer to the relevant instruction manual.
TYPICAL CONNECTIONS
High Vacuum Flange Connection
To connect the Turbo-V300SF pump to the ISO
inlet flange, remove the outer ring and position the
centering ring as shown in the figure.
Then fix the two flanges with the clamps or claws
as shown in the figure.
For ConFlat flange connections we recommend
using Varian hardware.
To facilitate assembly and dismantling, apply Fel-
pro C-100 high temperature lubricant to the screw
threads protruding from the flange and between
the nuts and flange.
Attach the units and tighten each one in turn. Repeat
the sequential tightening until the flange faces meet.
