2. Install the thermometer (A) and psychrometer (B) as shown in the figure.
3. Verification conditions:
- avoid exposing your car to direct sunlight;
- open the hood;
- open the front doors;
- set the temperature control to the "MAX COOL" position;
- set the mode to "VENT";

- set idle speed to 1500 rpm;
- there should be no people in the cabin during the inspection.
4. After 10 minutes of air conditioner operation under the specified conditions, measure the outlet temperature (in the area of the central deflector), inlet temperature (in the area of the heater fan unit), outlet pressure (high pressure line pressure gauge) and inlet pressure (low pressure line pressure gauge).
5. Make sure that the obtained values fall within the shaded area of the graphs.
