1. R1234YF Service Equipment Status of R1234YF Service Equipment 2/06/09

2. R1234YF Service Equipment New SAE Standards: J2843 Recovery Recycling Recharge Equipment for R1234YF J2851 Recovery Only Equipment for R1234YF

3. R1234YF Service Equipment SAE J2843 Same performance requirements as SAE J2788 95% Recovery Efficiency +/- 1 Ounce Recovery Accuracy +/- .5 Ounce Charge Accuracy Same purity requirements as SAE J2788 500 ppm HBR (Oil) 150 ppm Noncondensables 50 ppm moisture

4. R1234YF Service Equipment New Safety Requirements J2843/J2851 ANSI/ISA-S12.12.01-2000 Reference NFPA-70 and NFPA497 Class 1/Division2/Zone2 Class 1 Flammable gas or vapor Division 2 Flammable atmosphere only occurs due to abnormal operation leaks, lost ventilation, etc Zone 2 Flammable atmosphere is not likely to occur in normal operation

5. R1234YF Service Equipment SAE J2843 and J2851 new requirements : Class 1/Division 2/Zone 2 requires nonincendive method: Use of nonarcing make/break components by: Sealing Limiting current and voltage Using arc suppression methods Limiting the surface temperature of exposed components to < 405C

6. R1234YF Service Equipment SAE J2843 and J2851 new requirements: Control discharge of refrigerant normally vented during the service process. Collecting and directing refrigerant into the garage ventilation system. Air Purge Oil Drain Vacuum Pump Exhaust

7. R1234YF Service Equipment Other Changes from R-134a Equipment: New Charge Coupling and Hoses New unique tank fitting and tank color Air Purge Circuit Calibration

8. R1234YF Service Equipment Related standards: J2888 Service Standard for Hose, Fittings and Couplers for Mobile AC systems. J2844 Refrigerant and purity and container standards for refrigerant used in mobile equipment. J639 Revision Service ports for R1234YF

9. R1234YF Service Equipment Test Status: Prototypes deployed supporting mobile AC development . Months of operation with no issues. Recovery efficiency and charge accuracy same as R134a (as expected) Preliminary recycling testing being conducted.

10. R1234YF Service Equipment Open issues in finalizing standards and designs: Test agencies approved by the EPA (UL and ETL) have not committed to a plan for testing and certification. A proposed revision to UL1963 is being submitted to expedite final construction definition and test requirements. Need to take into account and incorporate global requirements.
