CHECKING THE EFFICIENCY OF THE AIR CONDITIONING SYSTEM
ALL TYPES
CHECKING PRESSURES
TOOLS - 1 Charging station.
- 2 Thermometers.
Once the preliminary conditions, vehicle equipment and checks have
been fulfilled (see table) : After the air conditioning has been on for three
minutes, record the following parameters :
CHECK
- The temperature of the air coming from the central vents (see table)
- The High Pressure.
- The Low Pressure.
Compare the values recorded with the table below, or the graphs.
