ACR2005 Refrigerant Service Solution
Operating Instructions
3. Press the NEXT key.
If the refrigerant has not been recovered, the ACR2005 will now identify
and recover. It then prompts you to make correct system connections (as
outlined above) before 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
from the system.
5. The display next 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, which could
result in personal injury!
6. The ACR2005 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 ACR2005. Remove this bottle, measure the oil,
and dispose of the oil correctly. 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. Re-configure the vehicle’s A/C system to the way it was before flushing.
10. Open the valve on the source tank.
11. Evacuate and recharge the vehicle following instructions on pages 17–19.
