refrigerant circuit and servicing (retrofit)
Note:
- 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.
- Air conditioning 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 .
Keeping refrigerant records
The environmental statistics law requires records to be kept
on the use of refrigerants.
Consequently, motor vehicle workshops may well have to
provide the relevant local authorities with information on
their use of refrigerant. It is therefore advisable to keep
records
