Operating Instructions
Follow these steps for refrigerant recovery and purging:
1. Refrigerant Recovery
- Connect the 'IN' port of the recovery machine to the system being recovered using appropriate hoses.
- Connect the 'OUT' port of the recovery machine to a certified recovery tank.
- Ensure all connections are tight and leak-free.
- Turn the control knob to either RECOVER SLOW or RECOVER FAST depending on the desired speed.
- Press the START button. The machine will begin recovering refrigerant.
- Monitor the pressure gauges during operation. The machine will automatically shut off if pressure exceeds 38.6 bar / 558 psi.
- Once recovery is complete, turn the control knob to OFF.
