After charging with refrigerant , the unit checks for any air in the cylinder. If air is detected, the system activates discharge for a
few seconds showing the message “Discharging non-condensable gases”. The discharge pressure may vary between 5 and 16 bar.
There are 3 LEDs (light emitting diodes) that indicate the cycle in progress. At the end of the cycle, the LED will remain lit to indicate
the completion of the cycle.
! Warning: the quantity of UV tracer required for the correct contrast depends on the nature of the product. The value indicated
under UV refers to contrast products sold by CTR

Procedure to empty pipes

5.5 “RECOVERY” operation
This function allows drawing all the refrigerant from the system and making it reusable by means of a complete ltering and
distillation process.
- 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 start the recovery cycle of the refrigerant in the circuit. During this operation, the display shows the general parameters,
and “GasR:” indicates the gas recovered and the time it took. There is a pause in the recovery phase when the pressure reaches
- 0.10 bar. (value controlled by the pressure sensor). The LED R (recovery) stays on for the entire duration of the cycle.
- 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 change into the gaseous state to be recovered. This phase is signalled by an increase
in the pressure indicated on the display under the item “P:” (pressure read by the sensor). After the pause, if the pressure has
increased, repeat the function a maximum of three times, while when there is no pressure end the cycle.
-
Pess the ESC button for 2 seconds during the operation to exit the phase and return to the main menu. In this case, you will not
be prompted to print the report.
- In the event of an emergency, press the red mushroom button on the control panel to completely turn off the unit; in this case,
the function that was in progress will not be stored.
- When the cycle has been completed, press the ESC button for 2 sec. to exit
- When you exit the operation you will be prompted to print the report. Press OK to print or ESC to return to the main menu.
-
All the refrigerant recovered in this operation increments a recovery counter to monitor the life of the filters; when a total of 150 kg
has been reached, a message will appear on the display warning you that the filters need to be replaced. The counter increments
by grams with resolution of 3g.
- In the event of an error, the display shows the relative message and activates an acoustic signal. To exit press the ESC button
- The time available for the operation is 30 min.
The old oil container must always be empty to prevent leaks.
