Volkswagen Polo Service & Repair Manual: Refrigerant Circuit

A/C System Repair Information

An A/C system made for refrigerant R12 must not be filled 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.
Components of R134a refrigerant circuits can be identified by their markings, green labels or design (such as different threads) to prevent interchanging with components designed for refrigerant R12.
A label indicating the refrigerant used is provided in the engine compartment on the lock carrier or in the plenum chamber.
Different refrigerants are never to be mixed.
  Note
When working on the refrigerant circuit, always heed the information given in the sections on “Safety measures”. Refer to → Chapter „A/C System and Refrigerant R134a Safety Precautions“ and “Basic rules for working on refrigerant circuit” → Chapter „Refrigerant Circuit, General Precautions“.
