Operating Instructions
3. Press the NEXT key.
If the refrigerant has not been recovered, the 342000 will now identify and
recover. It then prompts you to make proper system connections (as
outlined above) prior to evacuation or pulling a vacuum.
4. Press the VACUUM key. Choose the default or program the evacuation
time, then press the START key. The unit begins evacuation to remove air
in the system.
5. Next, the display asks for a flush time. The default time is 10 minutes.
You can change the flush time using the numeric keys. Press the START
key to accept the time and begin the flush procedure.
WARNING!
Do not disconnect service couplers during flushing. Doing
so will cause refrigerant to spray out of the fittings!
6. The 342000 flushes the system for the designated amount of time, then
goes into a CLEAR mode as it recovers refrigerant from the system.
NOTE: If the external flushing filter plugs, you will be prompted to
change the filter.
7. The unit automatically drains any collected oil into the graduated oil drain
bottle on the side of the 342000. Remove this bottle, measure the oil, and
dispose of the oil according to local, state, and federal regulations. Be sure
to replace lost oil with an equal amount of new oil.
8. The display shows FLUSHING COMPLETE when the process is finished.
Close service couplers on hoses and remove them.
9. Reconfigure the vehicle’s A/C system to the way it was prior to flushing.
10. Open the valve on the source tank.
11. Evacuate and recharge the vehicle following instructions on page 19.
