Central air of air is under a high pressure. DO NOT WEAKEN any connections and do not remove any components of system to its full discharge. The coolant of central air should be let out correctly in special capacity by the qualified expert. The coolant used in system, should not get on your skin and to eyes since there is a danger of frostbite. At contact of a coolant to an open flame there is an allocation of poisonous gas. Therefore smoking in operating time with a coolant is the extremely dangerous, in particular its inhalation паров through the lit cigaret. The coolant has bigger specific weight, than air, and can cause asthma at work with it indoors, such, as house garage. And at last, uncontrolled release of a coolant in the nature can cause a serious damage to environment, creating "greenhouse effect". |
Service
For ensuring operation of the conditioner with maximum efficiency it is necessary to carry out the following checks regularly:
|
|
- Check a driving belt. If it is worn-out or damaged, replace it (see. Head Routine maintenance of the car).
- Check system hoses. Look for cracks, swellings, hardenings and wear signs. Examine hoses and shtutserny connections on existence of vials of oil and leaks. At detection of any signs of wear, damages or leaks replace hoses.
- Examine condenser edges on existence in them the got stuck leaves, insects and other garbage. Use special «a crest for edges» or the compressed air for condenser cleaning.
- Make sure that the system is correctly charged by a coolant as it is described below.
- It is very useful to banish system within about 10 minutes not more rare than once a month, especially during winter time. System non-use can lead for a long time to hardening and the subsequent failure of epiploons of system.
- In connection with complexity of central air of air, and also that its service needs the special equipment, serious diagnostics of malfunctions and procedure of repair are not included in this Management. However, simple checks and procedures of replacement of components are given in this Chapter.
- The most widespread reason of bad cooling is low level of a charging of system a coolant. If you found appreciable reduction of an exit of cool air, the following fast check will help you to define, whether coolant level in system is lowered.
- Warm up the engine to normal working temperature.
- Establish the switch of temperature of the conditioner in the coldest situation, and the supercharger of air on a maximum. Open doors (to make sure that central air will not be switched off as soon as will cool salon).
- At the switched-on compressor - the coupling of the compressor will publish appreciable click, and its center will start to rotate - touch a pipe located closely to the right forward longeron of a frame, near a radiator.
- If you notice essential fall of temperature, it is probable, level of a coolant is in norm.
- If the inlet line became covered by hoarfrost or is to the touch colder, than an accumulator surface / дегидратора, means, level of a coolant is lower than norm. The charging of system should be made only by the qualified expert.
