Certification Training ManualThis program is not intended to gauge the technical skills of technicians regarding the diagnosis and repair of motor vehicle air conditioners. The basic goal of the technician Training and Certification program is to teach technicians how to properly recover and recycle refrigerant, and why it must be done to protect the environment. SEE INSTRUCTIONS FOR TAKING TEST AND OTHER INFORMATION ON INSIDE FRONT : CFC-12, HFC- 134a and HFO-1234yf* Refrigerant Recycling and Service Procedures for Mobile Air Conditioning Technicians * This MACS Technician Training Program conforms to and complies with the SAE International Standard J2845 HFO-1234yf Technician Training for Service and Containment of Refrigerants Used in Mobile A/C Systems.
When retrofitting an R-12 system to use R-134a or when removing R-12 (vehicle disposal), use service equipment designed for R-12 and certified to meet the requirements of SAE J1990 (R-12 recovery and recycle equipment). HFC-152a is an A2 flammable refrigerant as classified by ASHRAE 34 and should be used only with a second-ary loop application.
