Operation; Start Up Procedure; Shutdown Procedure - Agilent Technologies TriScroll 610 Installation And Operation Manual

Gas Ballast
The pump incorporates an automatic gas ballast to
prevent water and other condensates from accumulating
within the pump. The standard configuration is a sintered
filter installed in the 1/4 National Pipe Thread gas ballast
port (item 9 on Figure 1 on page 1). This allows enough
atmospheric air to enter the pump in order to purge
condensates while not effecting pump ultimate pressure
or pumping speed.
For applications where the ingress of atmospheric air is
undesirable, dry nitrogen at a flow rate of -5 lpm can be
bled into the gas ballast port. Blocking of the gas ballast
port is not recommended.
Bearing Purge
A 1/4 National Pipe Thread bearing purge port (item 6 on
Figure 1 on page 1) is provided to protect the main
crankshaft bearings in applications where large amounts
of water are being pumped. In the standard configuration,
the port is sealed. Contact Agilent for further information.
TriScroll 610 Dry Scroll Vacuum Pump

Operation

Unlike conventional oil-sealed pumps, Agilent's dry
scroll pumps contain no fluid to cleanse them of
accumulated dust and debris. Therefore, it is good
practice to run the pump periodically at atmosphere for a
minute or two to flush out the pump. Until experience is
gained on your specific process, flush the pump regularly
and adjust according to your specific conditions.

Start Up Procedure

1. Ensure that the vacuum system isolation valve is
closed.
2. Turn on pump.
3. Open the isolation valve.

Shutdown Procedure

1. Close the vacuum system isolation valve. This
prevents debris in pump from being transported into
the vacuum system.
2. Turn off pump.
