2401049 - 5040A CHECK ON OPERATION OF AIR CONDITIONING SYSTEM (TEMPERATURE)
 | The test must be carried out at
an external temperature ET between 18° Χ ανδ 30° Χ, on the
car when it has stabilised at this temperature. If the car comes
from an external environment with a temperature <18° C or >30°
Χ, it must be stabilised for 1h with the windows lowered. |
Connect the recharing device high and low
pressure pipes to the climate control system gas circuit filling
fittings.Open the ventilation outlet flaps (on the
facia) and introduce a thermometer (or suitable tool) into the central
outlet through the fins by about 30 mm.Close all the doors and windows.Start up the engine and let it idleTurn off the compressor (led on key off)Deactivate recirculation (orange led on
key off)Run fan at maximum speed by pressing button
10 until 12 bars appear on the central display. One minute after completing the above operations,
read temperature T0 reading on the thermometer and note it down.Check that external temperature ET has not
been exceeded by more than 5° CCheck that the pressure readings
on the pressure gauges in the high and low pressure fttings are
the same as one another and equal to:
- same as/about 5 bar for outdoor temperatures of about
20° Χ;
- same as/about 6 bar for outdoor temperatures of about
30° Χ
Activate recirculation by pressing key (led
on key on)Activate the compressor (led on key on)2 minutes after the compressor has been
switched on, check that the temperature of the air, shown on the
thermometer, has decreased by at least 8° C compared with the initial
value T0.5 minutes after the compressor has been
switched on, check that the temperature of the air, shown on the
thermometer, has decreased by at least 12° C compared with the
initial value T0. The radiator fan comes on at a pressure
value from 15 to 16 bars measured on the high pressure gauge.The fan goes off when the high pressure
drops from 11 to 12 bars.
