Verify that low and high pressure readings on gauges do not <br />fluctuate or go low. <br />2. Be aware that receiving tank for refrigerant being recovered <br />is pressurized prior to use. <br />3. Use a refrigerant leak detector if pressure drop is recognized <br />and undetectable. <br />4. Inspect tool prior to use, do not use if broken or <br />compromised. <br />M <br />Check Low and High Pressures <br />4. Evacuate and Recover <br />Refrigerant <br />- Overfill of Receiving Cylinder 1. Ensure that receiving tank is the correct type for the <br />refrigerant being recovered. Note: Tank cannot be filled more <br />than (2) lbs. less than 80% full. <br />M <br />Evacuate Refrigerant <br />5.
