Air conditioning Safety Precautions

Safety Precautions

The following safety precautions have to be observed for these cooling aids (additional laws may apply for different countries).

The assemblies and lines of the air conditioner are filled with the following refrigerant:

1.1.1.2 Tetrafluoroethane (CF(3)-CH(2)F or CH(2)F-CF(3))

This refrigerant is commonly known as R-134a, H-FKW 134a, SUVA 134a and KLEA 134a (in the USA different names may apply as well).

Refrigerant R-134A replaces the refrigerant R-12 which is reported to have harmful effects on the ozone layer of the earths atmosphere.

R-134a and R-12 systems are similar in design but there are very important differences in the refrigerants, lubricating oils, service equipment and A/C system components.
