Attention! The air conditioning system is under high pressure. Until the complete removal of the refrigerant, it is forbidden to disconnect any hoses and remove the units of the air conditioning system.
Attention! The removal of the refrigerant must be carried out in a car service.
Air conditioning care:
- checking the condition and tension of the compressor belt;
- checking the condition of hoses and tubes (highway to disconnect!);
- cleaning the intercostal spaces of the condenser;
- checking the system refrigerant charge.
The air conditioner should be turned on every month for about 10 minutes.
The most common cause of unsatisfactory air conditioner performance is insufficient refrigerant charge. If there is a noticeable increase in air temperature from the air conditioner, then check the completeness of the refrigerant charge.
