with refrigerant R134a without making modifications to the
refrigerant circuit. Refer to
→ Chapter „Refrigerant Circuit, Converting R12 to R134a and
Servicing“. |
| The refrigerant oils specifically developed for R134a and
R12 refrigerant circuits are never to be mixed. |
| Service stations which come in contact with the refrigerant
are only to be used for the intended refrigerant. |

by their markings, green labels or design (such as different
threads) to prevent interchanging with components designed for
refrigerant R12. |

engine compartment on the lock carrier or in the plenum chamber. |
| Different refrigerants are never to be mixed. |
