NOTE:
- As PAG (polyalkylene glycol) oil is highly hygroscopic (attracts water), opened containers are to be immediately re-sealed so as to be airtight.
- PAG oil from containers which have been open for a lengthy period is no longer usable.
NOTE:
- The oils used with refrigerant R12 are not suitable for refrigerant R134a.
- The name of the compressor manufacturer "Nippondenso" has been changed to "Denso".
- The refrigerant oil developed specially and exclusively for R134a refrigerant circuits is not commercially available.
- Refrigerant oils specifically designed for each compressor can therefore be obtained from the replacement parts range → Electronic Parts Catalog ETKA.
- The use of other refrigerant oils could cause system failure, as they do not always mix and thus circulate with refrigerant R134a (for compressor lubrication).
- There are different refrigerant oils for "Zexel" , "Denso" and "Sanden" compressors → Electronic Parts Catalog ETKA.
- The refrigerant oil (G 052 300 A2) for use in refrigerant circuits with "Denso" compressors (old name "Nippondenso" ) is also included in the retrofit kit (part number 4A0 298 107 A) → Electronic Parts Catalog ETKA.
- Use is to be made for refrigerant circuits with "Zexel" or "Sanden" compressor of refrigerant oil with part no. G 052 154 A2 → Electronic Parts Catalog ETKA.
- For refrigerant circuits with "Zexel" compressors, use can be made of both the refrigerant oil (G 052 154 A2) and the refrigerant oil (G 052 200 A2) contained in the retrofit kit (part no. 4A0 298 107) → Electronic Parts Catalog ETKA.
