Notes:
•
J2843 leak testing is intended to nd a gross leak
before charge, for safety reasons. It is not intended
to take the place of other established leak test
practices.
•
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.
