Prevention

The highway of air conditioning system is under high pressure. Before full removal of coolant it is forbidden to disconnect any hoses and to remove air conditioning system units.

Removal of coolant has to be carried out in car service.


Care of air conditioning system:

 – check of a state and tension of a compressor belt;
 – check of a condition of hoses and tubes (on to disunite the highway!);
 – cleaning of intercostal spaces of the condenser;
 – check of filling of system with coolant.

The conditioner should be turned on monthly approximately for 10 min.

Insufficient gas station of coolant is the most common cause of unsatisfactory operation of the conditioner. If noticeable temperature increase of air from the conditioner is observed, then check completeness of gas station of coolant.
