Recover/Recycle Refrigerant from
Vehicle

33
Be sure vehicle is at operating temperature before
recovering refrigerant.
1. Open red (vapor) recovery tank valve.
2. Connect service hoses to vehicle. For additional
information refer to Connecting Service Hoses to
Vehicle in this chapter.
3. Open:
— High (red) side service hose valve or coupler,
— Low (blue) side service hose valve or coupler,
— High (red) manifold hand valve, and
— Low (blue) manifold hand valve.
4. Turn compressor ON.
COMPRESSOR ON indicator illuminates and compressor
activates.
5. Turn vacuum/recycle valve to RECYCLE.
Refrigerant flows from vehicle, through
DDuuaall

, and
into recovery tank.
As refrigerant is recovered, the low side manifold gauge
shows increasing vacuum. Continue recovering until low
side manifold gauge indicates 15 inHg.
6. Close:
— High side manifold hand valve, and
— Low side manifold hand valve.
7. Turn vacuum/recycle valve to OFF.
8. Turn compressor switch OFF.
9. Monitor low side manifold pressure gauge for about 2
minutes.
— No change indicates recovery is complete. Continue
with system repair and/or evacuation.
— Pressure increase indicates more recovery time
required or vehicle A/C system has leak. Repeat
steps 3 through 9.
If gauge reading still increases, add partial charge to system
and leak test with electronic leak detector to find leak.
