Performance check

1. The vehicle to be tested must be installed in a place where there is no direct sunlight.

2. Close the high and low pressure gauge manifold valves.

3. Connect the charging hose (of blue color) to the low pressure valve and filling hose (Red) to the high pressure valve of the measuring manifold (pic. 18.7).



4. Install on the hose (of blue color) low-pressure quick-release fitting, and on the filling hose (Red) - quick-release high pressure fitting.

5. Connect the appropriate quick fittings to the low and high pressure service valves.

Warning. To install the quick fitting, firmly push the coupling part A towards the service valve until it clicks. After connecting the quick fitting, run your hand along the hose to ensure there are no kinks.

6. Start the engine.

7. Set the air conditioner mode switches to the following positions:

• air conditioner switch: ON position (included);
• ventilation mode selection knob: FACE position (face);
• temperature control: MAXIMUM COOLING position (maximum cooling);
• air supply mode: RECIRCULATION position (recycling);
• fan: FAST position (high speed).

8. Increase the engine speed to 1000 min^-1 with the electromagnetic clutch of the compressor engaged.


9. Warm up the engine with doors and windows closed.

10. Insert the thermometer into the ventilation grill and within 20 minutes measure the temperature of the air supplied to the passenger compartment (pic. 18.8).



11. Record the temperature of the air entering the passenger compartment.

Note: If the magnetic clutch starts disengaging, record the temperature before disengaging.
