Introduction of New Refrigerant
Introduction Of New Refrigerant-R134a
Volvo introduced refrigerant R134a from 1993 models on. Only this refrigerant may be used in A/C systems for which it is specified. R134a contains only fluorine, unlike R12, which is a chlorofluorocarbon (CFC).
The car is equipped with a sticker (11) in the engine compartment and a yellow tag around the service valve (9) to indicate that the system contains the new medium.
The components (1-9) listed below have been modified and adapted especially for R134a in the 1993 models.
Two new drainage and recycling units (RHS 850 and RHS 650) have been developed in conjunction with the introduction of the new refrigerant. The RHS 850 and RHS 650 units may be used to drain, purify and recover the refrigerant, in addition to vacuum-pumping, testing and refilling the A/C system in the car.
