• The 15% charge is automatically recovered before recharging the programmed amount.

• To avoid false failures, the temperatures of the vehicle system and the recovery machine should be within ± 5 degrees C.

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.
