Check of a central air of air

Air central air is under a high pressure. Do not try to weaken any connections or to remove details of system without a preliminary discharge of system. The coolant should be removed from system in a specialised workshop (the type of a used coolant is resulted in Specifications). Even after a system discharge at performance of any operations with system use goggles.

PERFORMANCE ORDER

That air central air functioned regularly, it is necessary to perform following operations regularly: Check up a condition приводного a belt. At detection of excessive deterioration or damages it is necessary to replace a belt (address to Section Check of a condition of ridge belts of a streaming drive of auxiliary units and the Head the Engine). Check up a condition of pipelines of system. Examine them in search of cracks, swellings and consolidations. Examine also штуцерные connections in search of traces of leaks. At detection of wear tracks, damages or leaks replace the damaged pipeline. Examine a surface of the heat exchanger located before a radiator of system of cooling. At detection of pollution of edges, insects, etc. clear a surface of the heat exchanger a special brush or compressed air. Be convinced of that the drainage tube of the evaporator is not littered. At the included conditioner from this tube should exude pure water. For check of cleanliness of a tube enclose under the evaporator a sheet of paper and include the conditioner. After some period of time on sheet there should be water traces. At use of compressed air use goggles. Include the conditioner at least once a month (even in the winter). If not to use the conditioner long time, it can lead to an exit of consolidations out of operation. Owing to complexity of system diagnostics and repair should be carried out on a car repair shop. Most a plausible reason of decrease in an overall performance of system is the coolant lack. If you have noticed sharp decrease in an overall performance of system, check up quantity of a coolant in system as follows. Warm up the engine to working temperature. The switch choose the lowest temperature of submitted air. Include the greatest speed of the fan. Open doors (that the system was not switched off after achievement of the demanded temperature in salon). At inclusion of its compressor муфта should publish heard click, and the central part муфты — to rotate. Touch inlet and a compressor exhaust pipe. One of them should be cold, another — hot. If you do not feel a difference, the system is faulty. It can be caused as a coolant lack, and something another. For malfunction elimination address on HUNDRED.
