In 1996 Systems Were Switched Over To R134A From R12 Refrigerant.
Repeat steps 3.ii.a through j two more times. Australian experience with retrofitting hydrocarbons to cfc 12 and hfc 134a macs. Cfc 12 from systems they have already retrofitted whilst spreading the workload and cost to the operator, over a period of time.
This Is Because Each Refrigerant Has Its Color Code.
Five case studies where r134a has been retrofitted in five different application sections are given at the end of the paper. Technician a says that the process doesn't take long but that mineral oil must be added before the retrofit is complete. General safety and service precautions;
Neither Technician A Nor B B.
