The prevention

Air central air is under a high pressure, therefore it is impossible to weaken any connections in a central air, pressure is not removed yet. A source of the raised danger at system improper maintenance by unprepared technicians and at use of the inadequate equipment is the high pressure and chemical influence of a coolant.


For effective work of a central air of air it is necessary to carry out following actions constantly:

 – To check and, if necessary, to regulate a tension приводного a belt of the compressor of the conditioner,
 – Constantly to check a condition of hoses,
 – Using cold water or compressed air, constantly to clear plates of the condenser,
 – To support exact level of a coolant in air central air.

Air central air should work at least 10 minutes at least, once a month.

The central air should be served by exclusively prepared technicians trained in safe working methods with application of the appropriate equipment, with observance of rules of the depressurization, acquainted with receptions of gathering and order of storage of an automobile coolant.

Do not suppose contact of a coolant to a skin.

At work near to a central air put on goggles.

At coolant hit on a skin or eyes do not pound the amazed place. Immediately wash out cold water within not less than 15 minutes. Immediately address to the doctor or a medical institution. Self-treatment is not supposed.

The coolant is in a new cylinder under pressure. Store at temperature not above 50 S.Prinimajte the measures excluding falling of a cylinder from height or other situations which can lead to its damage.

Works should be spent in well ventilated premise. The coolant quickly evaporates, leads to reduction of access of oxygen and to the complicated breath.

The gaseous coolant is heavier than air and rather quickly should gather from below, for example, under the car.

At coolant combustion poisonous gas is formed. Store a coolant far from open sources of fire. Do not smoke. At use ardent течеискателей avoid smoke inhalation.

At carrying out of welding works near to a central air always delete from it a coolant. Electric welding near to pipelines with a coolant can cause decomposition of a coolant under the influence of ultra-violet radiation.

Do not subject a detail of a central air to influence of a heat or an open flame. The overheat can lead to pressure increase in system and to ignition.
