Test conditions/preparations (Step 1)

  1. Connect the WAECO filling station to the low pressure side (L.T.) and the high pressure side (H.T.) on the air conditioner’s service connection.
  2. On vehicles with mechanical a thermostat, it must be ensured that the thermostat setting is correct and it should be adjusted if necessary (setting values: final position clockwise, 1/4 turn back, then adjustment).
  3. Start the engine and set the engine speed at 1500 – 2000 rpm.
  4. Start the air conditioning system by pressing air conditioning button.
  5. Select fan level 2 or 3.
  6. Measure the temperature in the vehicle and in the workshop with the thermometer.

Note

For outside temperatures above 28°C, the recirculation function must be selected (refer also to the vehicle manual) in order to prevent hot air from entering from the outside.

If the cabin temperature is lower
than the room temperature:

  • Let the air conditioner work under these conditions for 5 – 10 minutes.
  • Then carry out a performance check on the air conditioner.

If the cabin temperature is higher
than the outside temperature:

  • Open windows and doors. Wait until the indoor and outdoor temperatures have levelled off (or until a fairly even temperature level is achieved).
  • Close windows and doors.
  • Then carry out a performance check on the air conditioner.
