2. Set the maximum fan speed ("HI")
3. Set the air mixing damper to position "RECIRC" (recycling).
4. Turn on the air conditioner.
5. Open all doors.
6. Maintain idle speed at 1500 rpm.
7. Check the amount of refrigerant by the presence of bubbles in the service window of the receiver.
- A) If bubbles are visible in the service window (lack of refrigerant), then check for leaks in the system and top up the system to the correct level.
- b) If bubbles are not visible (either the amount of refrigerant is normal, or the system is recharged, or there is no refrigerant), then the method of elimination - see paragraphs. "V" And "G".
- V) If there is no temperature difference between the compressor inlet and outlet (either there is no refrigerant or the amount of refrigerant is minimal), check for refrigerant leaks, then charge the system to normal
- G) If there is a large temperature difference between the inlet and outlet of the compressor (either the amount of refrigerant is normal, or the system is recharged), then the method of elimination - see p.p. "d" And "e"
- d) If the refrigerant in the service window becomes transparent immediately after turning off the air conditioner (system recharge), then remove all refrigerant, evacuate and charge the system to normal.
- e) If the refrigerant foams and then becomes clear after the air conditioner is turned off, the refrigerant amount is normal. Coolant quantity 750±50 g.
