Arrangement of an observation port for definition of level of a coolant in air central air
Central air of air consists of the condenser established before a radiator, the evaporator located about a heater, the compressor established on the engine, and a degidrator. The fan of a heater banishes warm air in car salon via the evaporator, cools it to the demanded temperature.
Preventions
Central air of air 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 by unprepared technicians and when using the inadequate equipment is the high pressure and chemical influence of a coolant.
Central air should be served by exclusively prepared technicians trained in safe working methods with use of the appropriate equipment, with observance of rules of the depressurization, acquainted with receptions of collecting and order of storage of an automobile coolant.
Do not allow contact of a coolant to skin.
At work near central air put on goggles.
At coolant hit 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.
The coolant is in a new cylinder under pressure. To store at temperature not above 50 ° S.Prinimayte the measures excluding falling of a cylinder from height or other situations which can lead to its damage.
Works should be carried out in well ventilated room. The coolant quickly evaporates, leads to reduction of access of oxygen and to the complicated breath.
The gaseous coolant is heavier some air and rather quickly should gather below, for example, under the car.
At combustion of a coolant poisonous gas is formed. Store a coolant far from open sources of fire. Do not smoke. When using ardent techeiskatel avoid smoke inhalation.
At carrying out welding works near system кондицио nirovaniye always delete from it a coolant. Electric welding near pipelines with a coolant can cause coolant decomposition 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 pressure increase in system and to ignition.
Condenser or evaporator cleaning by means of water vapor is not allowed. It is necessary to use only cold water or the compressed air.
In central air the observation port intended for a rough estimate of level of the filled coolant (see fig. is provided. An arrangement of an observation port for definition of level of a coolant in air central air).
For check of level of a coolant start the engine and turn on the conditioner. At the working compressor in an observation port it should not be observed vials. Presence of vials at least and on a short period to the certificate ет about insufficient filling of a coolant. Emergence of signs of foaming on inside of viewing glass can indicate almost total absence of a coolant. For a complete recovery of operability of system кондиционирова a niya the highway of system should be pumped out, checked on tightness and refuel the prepared personnel with use of the appropriate equipment.
