9.Connect an R-22 cylinder with clean refrigerant to the suction pressure tap.

10.Connect the R-22 gauge set to the liquid line service valve and connect a recovery machine with an empty recovery tank to the gauge set.

11.Set the recovery machine for liquid recovery and start the recovery machine in accordance with the manufacturer’s instructions provided with the recovery system being used.

12.Open the gauge set valves to allow the recovery machine to run until a vacuum level less than 0" Hg (gauge pressure) is established in the existing system line set and indoor coil.

13.Invert the cylinder of clean R-22 and open its valve to allow liquid refrigerant to flow into the system through the vapor line valve.

14.After all of the liquid refrigerant has been recovered, switch the recovery machine to vapor recovery to allow the recovery machine to run until a vacuum level less than 0" Hg (gauge pressure) is established in the existing system line set and indoor coil in accordance with the manufacturer’s instructions provided with the recovery system being used.

NOTE: A single system flush should remove all of the mineral oil from the existing refrigerant lines and indoor coil. A second flushing may be done (using clean refrigerant) if insufficient amounts of mineral oil were removed during the first flush. A second flushing may be required to ensure that the maximum amount of oil is removed.

15.Close the valves on the inverted R-22 cylinder and gauge set.

16.Remove the recovery machine, gauges, R-22 cylinder and the field provided fitting installed in Step 6.
