| Sucking out the refrigerant gas |
| –
| Turn off the ignition and all electrical components. |
| –
| Connect the Climate control recovery, recycling and refill set or EQ 7098 -VAS 6008- → Chapter. |
| –
| Activate the Climate control recovery, recycling and refill set or EQ 7098 -VAS 6008- to suck out the refrigerant gas. |
Note | t
| During suction of the refrigerant gas, the oil present in the loop may also be sucked out. To ensure lubrication of the compressor, the refrigerant gas oil must be topped up. Refer to the specific repair manual for each vehicle → Heating, air conditioning; Rep. Gr.87. |
| t
| In vehicles equipped with an air conditioning compressor without Air conditioning magnetic coupling -N25- (with Adjustment valve for the air conditioning compressor -N280-) the engine may only run with the refrigerant gas loop empty for the amount of time that is strictly necessary, as the compressor will operate continuously. The engine speed must not exceed 2500 rpm. However, in vehicles equipped with an air conditioning compressor with Air conditioning magnetic coupling -N25-, this restriction does not apply, as the Air conditioning pressure switch -F129- or the High pressure sensor -G65- will check for the presence of refrigerant gas in the loop and switch off the Air conditioning magnetic coupler -N25- when the loop is empty. |
| t
| To avoid damage when the air conditioning compressor operates without an Air conditioning magnetic coupler -N25- (with Adjustment valve for the air conditioning compressor -N280-) with an empty refrigerant gas loop, the equipment has a device to make sure that oil is supplied. This means that approximately 40 to 50 cm3 of refrigerant gas oil remains in the air conditioning compressor. |
| t
| Do not start the engine with the refrigerant gas loop open. |
