Note

The laws and regulations listed below are applicable in Germany. Different or additional laws and regulations may apply in other countries.

Addresses in other countries can be obtained from the relevant authorities.

For environmental reasons and on account of the corresponding legislation, refrigerant R12 can no longer be manufactured or supplied. Refrigerant R134a has been developed as a replacement for R12.

A/C systems developed and designed for refrigerant R12 cannot however simply be charged with refrigerant R134a. To ensure trouble-free operation of the air conditioning system even after conversion, various components of the refrigerant circuit must be replaced.

A precise description of the conversion procedure and information on the servicing of converted refrigerant circuits can be found in Repair Manual: Air Conditioner with Refrigerant R12 Parts 2 and 3. This repair manual is only available in hard copy.
