Connect The Ixl120 System To Your Vacuum/Exhaust System And Interstage Connection (If Fitted) - Edwards iXL120N Instruction Manual

11. Store pump brackets for
later use.
12. The stacked iXL120 system
is ready for moving to its
final location; please refer
to Section 3.3 of the
manual.
3.5 Connect the iXL120 system to your vacuum/exhaust system and
interstage connection (if fitted)
Pipe the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases or
vapours to the surrounding atmosphere.
Do not operate the system with the exhaust pipeline blocked. If the exhaust pipeline is blocked,
the system can generate exhaust pipeline pressures of up to 3.5 bar (3.5 x 10
Do not reuse any O-ring or O-ring assembly and do not allow debris to get into the iXL120 system during installation.
When you connect your iXL120 system to your vacuum system, take note of the following:
To get the best pumping speed, ensure that the pipeline which connects the vacuum system to the iXL120

system is the minimum length possible and has an internal diameter not less than the iXL120 system
inlet-port.
Ensure that all components in the vacuum pipeline have a maximum pressure rating which is greater than the

highest pressure that can be generated in your system.
Incorporate flexible pipelines in the vacuum pipeline to reduce the transmission of vibration and to prevent

loading of coupling-joints. We recommend that you use Edwards braided flexible pipelines for exhaust
connection.
Adequately support vacuum/exhaust pipelines to prevent the transmission of stress to pipeline

coupling-joints.
Incorporate a pressure gauge in the inlet pipeline, as an aid to determining that the iXL120 system operates

correctly.
You must be able to isolate the iXL120 system inlet from the atmosphere and from your vacuum system if you

have pumped or produced corrosive chemicals.
Refer to Figure 2, items 17 and 5. Use the following procedure to connect the inlet and exhaust of the iXL120 system
to your vacuum inlet and exhaust pipeline:
1. Remove the blanking plate from the inlet of the iXL120 system.
2. If you are using the NW50 inlet port, then use the O-ring and NW50 Clamping ring supplied to connect the inlet-
flange (Figure 2, item 17a) of the iXL120 system to your vacuum system.
