8. Manual operation "RECOVERY"



1) LP and HP valves open

Connect up the high and low pressure hoses with the A/C plant.

Open the two high and low pressure valves HP-LP (ex. 1) or, in case of only one service

point, open the corresponding valve (ex. 2).

Use the SEL key to select RECOVERY, indicated by the side led light.

The display visualizes the word AUTO. By pressing the key OK, the unit will recover the entire

refrigerant in the circuit. It is possible to pre-set the quantity of refrigerant to be recovered by

using the "+" and "-" keys. In that case, the times T200 and T60 will be deactivated.

During this operation, it is possible to monitor the partial weight of gas recovered on the display.

Terminated the pressure in the A/C system, the display visualizes T200 (seconds) for eventual

refrigerant still blocked in the system in the form of micro-frozen granules of oil and humidity.

At the end, the machine discharges the oil recovered for 60 seconds. Once the oil discharge phase

has terminated, the recovery phase begins if pressure is present. At the end of this phase the total

quantity of refrigerant recovered is visualized and is followed by an acoustic signal indicating the end

of the operation. The data of the complete operation will be automatically printed.

Possible error codes:

E0 = Cylinder full. It is not possible to recover gas.

E1 = Excessive quantity of gas programmed for recovery.

E2 = Recovery time expired.

The RECOVERY operation must be carried out with the engine switched off.
