How to empty the hoses of the unit:

After having carried out the charging procedure, maintain the high and low pressure

hose connections but close the two HP-LP valves, start the vehicle engine and wait a few

minutes until the A/C plant is fully running.

In case of only one service point, close the HP or LP valve used and disconnect the hose

from the vehicle.

In case of two service points, disconnect the high pressure (HP) hose from the vehicle

and open the two valves HP-LP on the control panel to allow the gas contained in the

hoses to be discharged through the low pressure terminal to the vehicle. Wait until HP

and LP fall to about 2 bar, then disconnect the remaining low-pressure hose (LP).

Switch off the engine.

11. "AUTOMATIC" operation

This procedure allows the system to carry out gas recovery, recovered oil discharge, vacuum,

leakage control, oil charge and gas charge in a completely automatic mode and with invariable

times for each operation respect to the manual mode.

1- Setting oil charging

Connect up the high and low pressure hoses.

Open the HP and LP valves; we advice you to close the LP valve at the end of the

vacuum phase. If at the end of this phase it is not possible to close the LP valve, once

the charging operation has come to an end, wait for three minutes before starting the

A/C system, or, in case of only one service point, open the corresponding valve.

Use the SEL key to select AUTOMATIC, indicated by the lateral led light (fig. 1).

Once the AUTOMATIC operation has been selected, the led OIL position on the display

lights on and the programmed quantity 30 gr. (indicated as 0030) of fresh oil appears on

the display (fig. 1). This quantity can be changed by using the "+" and "-" keys.

Press the OK key to confirm.

The led light OIL disappears and the led GAS position lights on. The programmed

quantity 700 gr. (indicated as 00.70 kg) appears on the display and it can be changed

by using the "+" and "-" keys (fig. 2).

Press the OK key to confirm.

The led GAS disappears and the led START lights on to start the Automatic operation (fig. 3).

If the quantity of oil and refrigerant are lower than the minimum quantity, the error

codes E6-E9 will be visualized to indicate that you must restore the levels before

starting the operation, then re-select the AUTOMATIC phase.

During the operation, the display will visualize times, quantities and errors of the different phases.
