| All components of the refrigerant gas loop sent for quality evaluation should be properly closed (use the original plugs of the replacement part). |
| l
| Genuine replacement parts (air conditioning compressor, collection tank, liquid tank, evaporator and condenser) are filled with nitrogen. However, the gas gradually leaks out, causing the pressure to decrease to the point that when initially opening the component, no gas outflow is detected. |
| l
| 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 should 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. |
| l
| To avoid damage when the air conditioning compressor operates without the Air conditioning magnetic coupler -N25- (with Adjustment valve for the air conditioning compressor -N280-) with an empty refrigerant gas loop, the equipment is equipped with a device to ensure the oil supply. This means that 40 to 50 cm3 of refrigerant gas oil remains in the air conditioning compressor. |
| l
| Do not start the engine with the refrigerant gas loop open. |
