The refrigerant (R-134A)
A warning  Nodes systems with R-12 and R-134A are not interchangeable. Do not replace components of the system with R-134A nodes of the system with R-12 and vice versa. Mixing units of these two types of systems can lead to failure and damage to the nodes of the air conditioner.
System 134A refrigerant (R-134A)
In order to eliminate the use of refrigerants, chlorofluorocarbons (CFCs), which can destroy the ozone layer, Kia Motor Corp. introduced on this car a new cooling system that requires the use of the refrigerant CFC. The new refrigerant known as R-134a. For many properties, including the form and function, a new type of refrigerant R-12 is similar.
However R134a - based refrigerant is a hydrofluorocarbon (HFC), whereas R-12 - refrigerant CFC. Due to the lack of chlorine in the molecular structure R-134a applications it will not damage the ozone layer.
In most existing car air conditioners are used, requiring the use of R-12 as refrigerant. In the absence of specific labels denoting R-134A, on the nodes and supply lines of the refrigerant of the air conditioner is required to run the system of R-12 refrigerant.
Kia Motor Corp. began to produce some cars equipped with new air conditioners that require the use of refrigerant R-134A. To service the air conditioners to the R-134 special requirements that will be set out below. Refrigerant R-12 and components for it can only be used in systems for R-12 and R-134A refrigerant and components for it can only be used in systems for R-134a. Determination systems with R-134A and R-12
To determine the type of the air conditioner installed on the specific vehicle, check the main components and piping supplying the refrigerant of the air conditioner. If a system node will have a yellow sticker "R-134a NON-CFC", it is a system with R-134A, requiring the use Refrigerant-134a.
A warning Air conditioners with R-134a can also be identified by the identification plate and on the O-rings of green and brown colors (HNBR), used in the system.
If the air conditioner have any of these signs, indicating the R-134, the air conditioners may only be used refrigerant R-134a. If the air conditioner is not marked as a system with R-134a, as previously described, it is a system with R-12, requiring the use of R-12 refrigerant.
A warning Do not add refrigerant R-12 in the air conditioner, which requires the use of refrigerant R-134a.
He add R-134a refrigerant in the air conditioner, which requires the use of R-12 refrigerant.
Never mix two types of these refrigerants. This can result in damage to the air conditioner.
The nodes of the system with R-134a
The basic units of air conditioners with R-134a are similar sites previously used in a system with an R-12. According to the construction and functions of the system units with R-12 and R-134a are similar. Therefore, all operations for removing and installing described for nodes with R-12 can be applied to nodes with R-134a. Safety measures
| PERFORMANCE ORDER | | 1. Liquid R-134a refrigerant is very volatile. Hit it drop on the skin can cause local freezing. When the refrigerant do not forget to wear gloves. |  | 2. If splashed coolant in your eyes, immediately rinse them with clean water. To protect your eyes, always wear protective glasses or ordinary. | 3. The capacity to R-134a is a vessel under high pressure.
Never expose it to intense heat and make sure to store it at a temperature not exceeding 52 ?� C. |  | 4. Often the system checked for leaks using a halide leak detector. Upon contact with the flame of R-134a forms the toxic gas phosgene. Always provide adequate ventilation. |
