GENERAL INFORMATION

Arrangement of the main knots of the air conditioning system
1 – condenser;
2 – compressor;
3 – receiver;
4 – evaporator;
5 – valve

Arrangement of an observation port for determination of level of coolant in the air conditioning system

The air conditioning system consists of the condenser installed before a radiator, the evaporator located near the heater, the compressor installed on the engine and a dehydrator. The fan of a heater banishes warm air in salon of the car via the evaporator, cools it up to the demanded temperature.

Preventions

The air conditioning system is under 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.

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.

Do not allow contact of coolant with skin.

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. To 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 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 system konditsio nirovaniye 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.

Cleaning of the condenser or evaporator by means of water vapor is not allowed. It is necessary to use only cold water or compressed air.

The observation port intended for a rough estimate of level of the filled coolant (see rice is provided in central air. An arrangement of an observation port for determination of level of coolant in the air conditioning system).

For check of level of coolant start the engine and turn on the conditioner. At the working compressor in an observation port it should not be observed bubbles. Presence of bubbles at least and on a short period to the certificate et about insufficient gas station of coolant. Emergence of signs of foaming on inside of viewing glass can specify almost total absence of coolant. For a complete recovery of operability of system of a konditsionirov the niya the highway of system has to be pumped out, checked for tightness and refuel the prepared personnel with use of the appropriate equipment.
