At inlet:
Screen filter
Check that an inlet screen accessory is installed on the pump ; if not,
install it. (pumps are delivered with inlet screen filter).
It is recommended to install an isolation valve between the chamber to
allow chamber venting without stopping the pump.
When pumping on corrosive gases, or aggressive gases, the gas can
cause injury or death. The exhaust of the turbopump must be connected
to roughing pump line compatible with process gases.
It is highly recommended to install an isolation valve (closed when
power is off) between the turbo pump and the roughing circuit.
At exhaust
The turbomolecular pumps can’t evacuate at atmospheric pressure, they
are connected to a roughing pump. For a transient period, they can start
to run at atmospheric pressure.
The valve is opened using the «START» contact on the controller.
If the valve is missing, the time taken to slow down the pump is
increased, thereby reducing the service lifetime of the back-up ball
bearings.
Connect this valve
V1
nearer to pump exhaust using connecting
accessories available in the manufacturer’s catalog.
Connect the valve to the primary pump.
