Question

Technician A says that HEV refrigerant service uses the same RRR machine as any other vehicle. Technician B says that a hybrid-specific RRR machine is used to service HEV systems. Which technician is correct?

Answer 1

Both technicians are correct.

Step-by-step explanation:

Recovery Recycle and Recharge (RRR) machines that meet SAE specification J2788H can be used to services HEV(hybrid electric motor) with electrically driven compressors. These machines have or can be used with filters to prevent mixing of a harmful amount of oil and refrigerant in the compressor, during charging of these hybrid vehicles. It is also designed to remove other particulate contaminant like dye from the refrigerant as well.
