If lubricant is removed by recovery equipment during system refrigerant removal, what must be
done with the lubricant?
Re-install lubricant removed by the recovery equipment
Before reuse, what must be done with HFC-134a that has been recovered from a mobile A/C
system using recovery-only equipment?
Question 2 options:
Recycle the HFC-134a before reuse using certified equipment
When can HFC-134a become combustible in a mobile air conditioning system?
If shop air is used in the system in an attempt to check for leaks and HFC-134a is present
Which type of mobile A/C system will usually require additional time / precautions to extract all
the refrigerant?
Accumulator type
Electronic leak detectors certified to SAE J2791 have the capacity of identifying leakage rates as
low as:
0.15 ounces per year
When recovery/recycling equipment is used to remove refrigerant from a mobile A/C system,
how much lubricant will be removed during the operation?
Generally, very little, if any
