Possible solutions
Increase the vacuum phase
time, check the A/C system
tightness.
Increase the vacuum phase
time, check the A/C system
tightness.
Decrease quantity of gas by
filling (charging) an external
tank rated for R134a (with
safety valve)
Check the connections and
make sure that the identifier
led is on, then repeat the
procedure
Check with virgin refrigerant
bottle if the refrigerant gas
identifier is working properly. If
yes and the refrigerant of the
car is not R1234yf, empty in a
safety way and in compliance
