Checking the roughing pump oil level
To ensure correct operation of the roughing pump, do not operate it with the
oil level at less than 30% of the maximum level, as indicated in the pump’s
sight glass.
Note:
This procedure is not required for an Edwards oil-free roughing pump.
The roughing pump oil level appears in the roughing pump’s oil level sight
glass. Check the oil level weekly; you must maintain the oil level at or near
the indicated maximum level when the pump is not operating.
Requirement:
You must check the oil level while the roughing pump is
running. Note that the oil level in the sight glass is lower when the pump is
running than when it is stopped. When the pump is running, the oil level is
typically at 30% to 60% of the maximum level.
Adding oil to the roughing pump
If the roughing pump’s oil level is low, you must add oil to the pump.
Required materials
•
Chemical-resistant, powder-free gloves
•
8-mm Allen wrench
•
Container to catch used oil
•
Funnel
•
Anderol vacuum oil, type GS 495
Warning:
To avoid personal contamination with biologically
hazardous, or toxic materials, and to avoid spreading
contamination to uncontaminated surfaces, wear clean,
chemical-resistant, powder-free gloves when adding or
replacing oil. The pump oil can be contaminated with analyte
accumulated during normal operation.
Warning:
To avoid burn injuries, take great care while
working with the roughing pump; it can be hot.
