Never mount oil and water extractor on or near the air com pres sor.
During compression, air temperature is greatly increased. As the air cools down to room tem p er a t ure, moisture condenses in the air line, on
its way to the spray gun. Therefore, always mount the oil and water extractor at a point in the air supply system where the compressed air
temperature is lowest.
Drain air lines properly.
Pitch all air lines back towards the com p res s or so that con d ensed mois t ure will flow back into the air receiver where it can be drained off.
Each low point in an air line acts as a water trap. Such points should be fitted with an easily accessible drain. See diagram above.
This spray gun is rugged in construction, and is built to yield exceptional value. The life of this product and the efficiency of its
operation depend upon a knowledge of its construction, use and maintenance.
