^
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose, and throat. Use only approved recovery/recycling
equipment to discharge R-134a systems.
^
If accidental system discharge occurs, ventilate the work area before resuming service work.
^
R-134a and R-12 A/C components are not interchangeable. Cleaning of used (in service) components for use with another type of refrigerant and/or
lubricant is not an acceptable practice, and may result in A/C system failure.
^
Always use the proper PAG oil when servicing an R-134a A/C system. The Nissan part number for the appropriate PAG compressor oil can be found
on the A/C specification label in the engine compartment, and also in the Factory Service Manual, and on the label on the compressor. These oils are
only available from your Nissan Parts Department.
^
When leak checking an R-134a system, be certain that you are using a detector which will detect R-134a.
^
As mentioned previously in this bulletin, the R-134a PAG lubricants absorb moisture; PAG oil containers and A/C components containing PAG oil
must remain tightly sealed until ready for use.
^
Unlike R-12 systems, R-134a systems do not exhibit a "clear sight glass", even when properly charged. For this reason, the R-134a A/C systems have
no sight glass.
^
With R-134a systems it is important to properly control the amount of refrigerant charged into the system during system charging. A charging
machine or weight scale must always be used during charging for proper charge determination.
^
Questions regarding R-12 or R-134a should be addressed to your Regional Service Staff or the FIXS Hotline.
