12. Press START, and the unit will automatically run a
five-minute vacuum to clear all internal air.
13. After the vacuum is complete, press START to begin
filling the internal storage vessel.
14. The unit stops when a sufficient amount of refrigerant
has been transferred to the internal tank, or when the
source tank is empty. Press the STOP key to pause the
process. Press STOP again to exit, or START to
resume. This process takes 15-20 minutes.
NOTE: Add at least 8 lb. (3.6 kg) of refrigerant before
stopping the process to ensure enough refrigerant is available
for charging.
15. When the fill process is complete, you may press STOP
to exit.
16. The unit is now ready to operate.
NOTE: There is no need to calibrate the scale, because it is
calibrated at the factory.
