EXECUTING THE OPERATOR-CONTROLLED CYCLE
- Connect the high and low pressure pipes to the A/C system
- Open the HP and LP valves, or if there is only one service point, open the corresponding valve.
- Select “AUTOMATIC” with the “+ ↑” and “- ↓ ” buttons. Press OK to start the cycle (Fig.1)

> START CYCLE
- When the “Manual” mode is selected, the system will directly suggest a fixed quantity of gas, which is 500 g (default Customizing
in Service menu), and the grams of oil calculated on the quantity of refrigerant set. You can also change the values suggested for
gas, new oil and vacuum (fig.5), using the “customizing” function in the SERVICE menu.
- Move the cursor “>” to “Start cycle” and press OK to start the operation. Once the cycle has been started, if conditions permit,
the system performs the cycle and displays all the current phases with values and text messages
.
Changing gas quantity, new oil quantity and vacuum time
To change a quantity, move the cursor “>” to the item involved (Fig.5), press OK to select it and use the “+ ↑” and “- ↓
” buttons to change the value. Changes are made in 5 g steps for gas, in 1 gram steps for new oil and in 5 minutes steps for
vacuum. To disable an item, set the value to zero.
5.5 “RECOVERY” operation
“RECOVERY” operation
With this function, the system draws all of the refrigerant from the system and makes it reusable by means of a complete filtering
and distillation process.
The RECOVERY cycle can be performed in two ways:
1 - Total recovery “AUTO” cycle
2 - Partial recovery cycle “g to recover”
Executing total recovery “AUTO” cycle
- Connect the high and low pressure pipes to the A/C system
- Open the HP and LP valves, or if there is only one service point, open the corresponding valve.
- Select RECOVERY with the “+ ↑” and “- ↓ ” buttons.
Press “OK” to enter the “AUTO” cycle and recover refrigerant until there is no pressure. To start the recovery cycle press OK. During
this operation, the display shows the general parameters, and “GasR:” indicates the gas recovered and the time taken. There is a
pause in the recovery phase when atmospheric pressure is reached. (value controlled by the pressure sensor).
- This period lasts about 4 min , including old oil discharge, in order to allow any refrigerant that has remained blocked in the low
pressure and temperature A/C system to expand for recovery. This phase is indicated by an increase in pressure shown on the
