- 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.
8. Manual operation “RECOVERY”
1- Quantity of gas
during the recovery
2- Wait
3- Oil discharge
4- End of operation
(Ex. 1,5 Kg. gas recovered)
The RECOVERY operation must be carried out with the engine switched off.
