10. Manual operation "CHARGING"

This function of the system allows refrigerant liquid and oil to be injected into the system

according to a pre-programmed quantity.



1- Setting oil charging

Connect up the high and low pressure hoses.

We advice you to open only the HP valve.

If the HP service point is not present, the charge must be carried out in LP. At the end

wait for three minutes before starting the A/C system.

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

Once the CHARGING 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 of 700 gr. (indicated as 00.70 kg.) appears on the display (fig. 2) and it can

be changed by using the "+" and "-" keys.

Press the OK key to confirm.

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

During the oil and gas charging the display visualizes the grams with a margin of error of 10 gr.

Oil will be charged only after the vacuum operation has been carried out in the A/C system.

If the quantity of oil and refrigerant are lower than the min. 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 CHARGING phase.

Acoustic sound of end operation and data printing.

Wait for three minutes before starting the A/C system.

Possible error codes:

E6 = Insufficient quantity of refrigerant for programmed charge.

E7 = Refrigerant/oil charge time expired.

E9 = Insufficient quantity of oil injection.

Min. level of refrigerant in the cylinder = 1 Kg.

Min. level of fresh oil in the container = 100 gr.

Sometimes, at the end of charging, you could hear a pressure leak and a countdown will

appear on the display. This is the automatic function of air discharge or incondensable

gases from the cylinder.

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