Note:
Equipment used to remove HFC-134a refrigerant (R-134a) from air conditioning systems must be certified and meet the requirements of UL and SAE J2210.
In the event of an accidental release of refrigerant, ventilate the room before resuming work.
Additional health and safety information can be obtained from the refrigerant and oil manufacturers.
