Mastercool 69788 RECOVERY_RECYCLE_RECHARGE - Manual (Page 18)

Press START: the machine will begin to discharge the air and the pressure value on the screen will gradually decrees.
Press STOP when the pressure is approximately 5 to 10 PSI higher than what the P/T chart say’s it should be for the temperature showing on the
screen. For example, if Tp is 140 PSI and the T is 80 degree F. The P/T chart say’s that the pressure at 80˚F should be 86.8 PSI. That means that
there is approximately 53 PSI of NCG. In this case, stopping the purge at 90-95 PSI will be sufficient enough for 69788 to operate properly while not
releasing too much refrigerant. It’s normal and unavoidable that a small amount of refrigerant is lost while purging.
NOTE: Purging to a pressure lower than what is determined from the P/T chart will result in a large loss of refrigerant.
