Charge continued
CAUTION: If the low-side (blue) or high-
side (red) coupler valve is left open
during the hose clearing process, the
system will pull refrigerant back out of
the vehicle.
Note: The charge process includes an
automatic vacuum leak test, after which the
system is pressurized with a small amount
of refrigerant for a manual leak test.
•
If the leak test passes, the refrigerant is
automatically recovered and the selected
charge is added.
•
If the leak test fails, the refrigerant needs
to be recovered and the vehicle needs
to be checked for leaks by using an
electronic leak detector.
