Main knots of the air conditioning system
The air conditioning system is under a high pressure therefore it is impossible to weaken any connections in central air, pressure is not removed yet. A source of the increased danger at improper maintenance of system unprepared technicians and when using the inadequate equipment is the high pressure and chemical influence of coolant.
For effective operation of the air conditioning system it is necessary to carry out the following actions constantly:
Central air has to be served by exclusively prepared technicians trained in safe working methods with use of the appropriate equipment, with observance of rules of depressurization, acquainted with methods of collecting and order of storage of automobile coolant.
During the work near central air put on goggles.
At hit of coolant on skin or eyes do not pound the struck place. Immediately wash out cold water within not less than 15 minutes. Immediately address to the doctor or medical institution. Self-treatment is not allowed.
Coolant is in a new cylinder under pressure. Store at a temperature not above 50 °C. Take the measures excluding falling of a cylinder about heights or other situations which can lead to its damage.
Works should be carried out in well ventilated room. Coolant quickly evaporates, leads to reduction of access of oxygen and to the complicated breath.
Gaseous coolant is heavier than air and rather quickly has to gather from below, for example, under the car.
At combustion of coolant poisonous gas is formed. Store coolant far from open sources of fire. Do not smoke. When using ardent techeiskatel avoid inhalation of a smoke.
When carrying out welding works near central air always delete from it coolant. Electric welding near pipelines with coolant can cause decomposition of coolant under the influence of ultra-violet radiation.
Do not subject central air detail to influence of high temperature or an open flame. The overheat can lead to increase of pressure in system and to ignition.
