This product must be used in accordance to the following directions by HVACR professionals only.

Change the oil in the vacuum pump after every use of the pump.

During pump operation, moisture as well as other contaminants like acids, vapors, etc. are easily absorbed into the vacuum pump oil. If the vacuum pump oil is not changed after absorbing such contaminants, it will become dirty and keep the pump from performing at design capacity (i.e., it will not reach its ultimate vacuum). Moreover, this will result in longer pump down time as well as excessive wear on integral parts of the pump.

Drain used oil from pump. If it appears exceptionally dirty or sludged, power flush the pump according to the pump manufacturer’s recommendations; power flushing helps to cleanse the pump of the old contaminated oil residuals. After power flushing, refill pump with fresh, new vacuum pump oil. View oil through sightglass and test the unit’s ultimate vacuum. If oil appears dirty or if vacuum is unsatisfactory, change oil again.

See back side of bulletin for oil changing capacities for some of the more frequently used vacuum pumps.
