3.3 Locate the iXL120
Use the following procedure to locate the iXL120 system in its operating position. The iXL120 system must be located
on a firm, level surface (with less than 3 degrees slope), to ensure that the system is not damaged and operates
reliably.
1. Use suitable lifting equipment (refer to Section 3.2) to move the iXL120 system close to its final operating
position.
2. Adjust the levelling feet to make sure that the iXL120 system is level and is not supported by the castors.
3. The lifting brackets should be removed and retained.
4. If you want to secure the iXL120 system in place to prevent inadvertent movement (for example, during an
earthquake), take note of the following:
The iXL120 system lifting brackets (retained in Step 3 above) can be used for seismic restraint, shown in
(Figure 2, item 3). They are designed to withstand a level 4 earthquake in a ground floor installation and are
capable of restraining two systems when stacked.
The iXL120 system can be secured to the floor by fitting suitable bolts or studs (not supplied) through the
slotted hole in the brackets.
If vibration transmission to the floor is a concern, suitable vibration isolators (not supplied) should be fitted
between the brackets and the bolt or stud.
3.4 Connect the iXL120 system to your vacuum/exhaust system and
interstage connection (if fitted)
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.
You must use suitable lifting equipment to move the system. It is too heavy to lift by hand.
Do not exceed the topple angle of 10° when moving the pump. Wheel the system on its castors to
move it into its operating position. The system should only be wheeled short distances over flat
surfaces. If the floor surface is uneven or has obstacles the system should be lifted with suitable
lifting equipment.
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
5
Pa).
