The oil and water extractor should not be mounted on or near the air
compressor.
The temperature of air is greatly increased during compression. As the air
cools down to room temperature, in the air line, on its way to the Air Power
Tool, the moisture contained in it condenses. Thus, for maximum
effectiveness, the oil and water extractor should be mounted at some point

in the air supply system where the temperature of the compressed air in the
line is likely to be lowest. Air lines must be properly drained daily. Each low
point in an air line acts as a water trap. Such points should be fitted with an
easily accessible drain. See diagram below. Pitch all air lines back towards
the compressor so that condensed moisture will flow back into the air
receiver where it can be drained off. Drain daily.
