(2) Place the compressor at a position above the ground level and then pour out the oil from the air outlet of
the compressor. Collect the oil in a transparent container. The amount of oil should be over 150ml.
NOTE:
1) The axial direction of the compressor should not slant at an angle larger than 20° to the horizontal
direction.
2) Prevent the compressor from falling.
3) Put a transparent container (over 150ml in volume) under the exhaust pipe to collect the compressor
oil, thus we can see the oil quality.
(3) Put the container of compressor lubricant in a bright location and see if there is impurity and
discoloration. Sniff at the compressor lubricant. Normally, there is no pungent smell.
(b) If the oil is contaminated, replace the compressor and the gas-liquid separator.
NOTE:
Confirm whether the compressor needs to be replaced. The pipe mouths of the faulted compressor must be
sealed by adhesive tape as soon as the compressor is detached. Make sure the compressor is well preserved for the
ease of future analysis.
Step 6: Check the components
If the oil is contaminated, check the components of the unit, including the gas-liquid separator.
Check the gas-liquid separator
