Oil Sampling
WARNING
When working with LFG, NG or other dangerous
or fl ammable gases, ensure there are adequate
ventilation and vapor detectors. Refer to national fi re
and building codes. Failure to comply may result in
serious injury or death.

rubber gloves and a face shield when working with
condensate or oil. Failure to comply may result in

Use Vilter Oil Analysis Kit (VPN 3097A) to collect an oil
sample for analysis. For an example, see Figure 5-2. Fill
out label for bottle. Place in mailing tube and seal with
the preaddressed mailing label. Below are a few points
to remember when taking a sample:
• Sample running compressor units, not cold units.
• Sample upstream of the oil fi lter.
• Create specifi c written procedures for sampling.
• Ensure sampling valves and devices are thoroughly
fl ushed prior to taking a sample.
• Ensure samples are taken as scheduled in the
Maintenance and Service Schedule.
• Send samples immediately to the oil analysis lab after
sampling, do not wait 24 hours.
Section 5 • Maintenance/Service
NOTE
A copy of the oil analysis report is also sent to Vilter. See
Appendices for a sample of the oil analysis report.
An oil analysis report will show the physical properties of
the oil, such as:
• Water content
• Viscosity
• Acid number
• Particle count
• Antioxidant level
• Wear metals
• Contaminate/additive metals
