CHECKING THE EFFICIENCY OF THE AIR CONDITIONING SYSTEM
Checking pressures
Tools. 1
charging station. 2thermometers.
Once the preliminary conditions, vehicle equipment and checks havebeen 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.
