Replacing The Roughing Pump Oil - Waters Xevo TQ-S micro Overview And Maintenance Manual

Replacing the roughing pump oil

Change the roughing pump oil annually.
Note:
This procedure is not required for an Edwards oil-free roughing pump.
Required materials
• Chemical-resistant, powder-free gloves
• 8-mm Allen wrench
• Flat-blade screwdriver
• Container to catch used oil
• Funnel
• 1-L container of Anderol vacuum oil, type GS 495
To replace the roughing pump oil:
1. Gas ballast the roughing pump for 1 hour, to reduce the oil's viscosity (see
page 110).
Rationale:
before draining.
2. Vent and shut down the instrument (see the mass spectrometer's online Help for
details).
3. Allow the roughing pump to cool.
4. Place the container for used oil under the pump's drain plug.
Gas ballasting helps to circulate and mix the oil through the pump
Warning:
To avoid personal contamination with biohazards or toxic
materials, and to avoid spreading contamination to uncontaminated
surfaces, wear clean, chemical-resistant, powder-free gloves when
adding or replacing oil. The roughing pump oil can be irritant, or
contaminated with biohazardous or toxic analyte accumulated during
normal operation.
Warning: To avoid burn injuries, take great care while working with
the roughing pump; it can be hot.
