6. Upon pressing the START key, the 342000 begins to charge the A/C
system.
IMPORTANT: Do not disturb or bump the 342000 during charge
as any jarring movement can affect the charge accuracy.
NOTE: If insufficient pressure differential exists between the tank and
system, charging suspends and the 342000 goes into a power charge mode
to increase tank pressure to complete the charge. This normally occurs
only when the 342000 has been in a very cool environment prior to use.
7. When charging is complete, the red indicator light flashes and the beeper
sounds to indicate the process is complete. The 342000 automatically goes
to the SNAPSHOT mode, allowing you to provide an after-service snap-
shot of key operating information. See page 14 for details on the SNAP-
SHOT mode.
8. Press the DONE key to exit the SNAPSHOT mode and prepare for the
next service job or press CHARGE MORE to add more refrigerant.
IMPORTANT: You are now prompted to close the service cou-
plers and disconnect the service hoses. This step is very im-
portant to ensure the 342000 recovers any residual refrigerant
from the hoses.
Failure to disconnect hoses will result in recovery of the
vehicle’s refrigerant.
Replace caps on the vehicle’s access ports.
9. Press the START key to recover refrigerant from the hoses.
WARNING!
Always close the service couplers prior to disconnecting
from the system to prevent any release of refrigerant.
