Thermo King – Recovery from a Operating Unit

If a unit is operable and the compressor functions, the refrigerant should be removed as a liquid. This is the fastest and most efficient method. Proceed as follows to remove refrigerant as a liquid:
1. Install a calibrated gauge manifold.
2. Attach a service line between the receiver tank outlet service port and the recovery machine inlet.
3. Pump down the unit’s low side to force the refrigerant into the condenser and receiver tank.
4. Set the recovery machine for liquid recovery and remove the refrigerant through the receiver tank outlet service valve.
