Check of the air conditioning system

The air conditioning system is under high pressure. Do not try to weaken some associations or to accept system details without preliminary discharge of system. Coolant has to be removed from system in the allocated workshop (the type of the used coolant is given in specifications). Even you use after a system discharge at execution of some operations with system goggles.

That the air conditioning system functioned regularly, it is regularly necessary to perform the following operations:

   a) Check a condition of priwodnogo of a belt. At detection of the increased sale or damages a belt (watch office it is necessary to replace check of a condition of ridge serpantinnogo belts of an incentive of auxiliary devices);
   b) Check a condition of pipelines of system. You look at them in search of cracks, swellings and a condensation. You look also association schtuzernyje in search of vytecheniye traces. At detection of traces of sale, damages or a vytecheniye you replace the damaged pipeline.
   c) You look at a surface of Wärmeübertragers which is located in front of the cooling system heater. At detection of pollution of regions, insects you clean Wärmeübertragers surface from a special hand or compressed air, etc.

At the appendix of compressed air you use goggles!


   d) are convinced of what the listener of a drainage of Verdampfers did not pollute. The made conditioner from this listener has to have sotschitsja clear water. For check of purity of the listener the sheet of paper which lost you under Verdampfer will also accept the conditioner. After some period of time traces of water have to appear on a leaf.

Accept the conditioner even if once a month (even in the winter). If not to use the conditioner long time, it can lead to a condensation exit except the enterprise.

Owing to complexity of system diagnostics and repair in service station have to be filled.

The most probable cause of immersion of overall performance of system is a lack of coolant. If you noticed strong immersion of overall performance of system, check amount of coolant in system the next way.

 EXECUTION ORDER

1. Heat the motor up to working temperature.
2. With the switch you choose the lowest temperature of the served air. Will accept the highest speed of the fan. Open doors (at the same time system it was not excluded after achievement of the necessary temperature in salon).
3. At application of its mufta compressor has to transfer the belonging click on a nose and remove, the central part of mufty, itself. Concern a pipe of access and sewer of the compressor. One of them has to be cold hot, others. If you do not feel distinction, the system is wrong. It can be caused as a lack of coolant, and something from another. For elimination of defect address on 100.
