CHECKING THE EFFICIENCY OF THE AIR CONDITIONING SYSTEM
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:
- 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.
