This overview is designed as a quick reference when using your unit. Read and follow all
warnings in the operating manual.
RECOVERY OVERVIEW
1. Connect the high and low side hoses to the A/C-R system.
2. Check the manifold gauges. There must be pressure to recover refrigerant.
3. Be sure both the high and low side valves on the control panel are open. Also be
sure both valves on the tank are open.
4. Plug the unit into the proper voltage outlet, then turn on the
MAIN POWER switch.
5. Press SHIFT/RESET, then press RECOVER:
• If there is pressure in the unit, the self-clearing process starts.
• If there is no internal pressure, refrigerant recovery begins.
• The unit then shows “RECOVER AUTOMATIC” and the weight of refrigerant
being recovered into the tank.
6. Once the recovery and/or self-clearing procedure is complete, the compressor will
shut off automatically. The display will flash “CPL” and the weight of refrigerant
recovered.
7. If the A/C-R system pressure rises above zero, you can press HOLD/CONT to
recover the remaining refrigerant.
8. The display also shows “OIL (OUNCES).” This is a reminder to drain the system
oil separator into a suitable container by opening the ball valve on the side of the
unit.
You must replace any oil lost from the A/C-R system during recovery with new oil.
Dispose of waste oil in an appropriate manner.
