Precautions for Working with HFC-134a
(R-134a)
WARNING:I CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant must never be mixed, even in the
smallest amounts, as they are incompatible with each other. If the refrigerants are mixed, com-
pressor failure is likely to occur.
I Use only specified lubrication oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a)
components. If lubrication oil other than that specified is used, compressor failure is likely to
occur.
I The specified HFC-134a (R-134a) lubrication oil absorbs moisture from the atmosphere at a rapid
rate, therefore the following handling precautions must be observed:
a: When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize the entry of moisture from the atmosphere.
b: When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before connecting the components. Also, complete the connection of all refrigerant loop
components as quickly as possible to minimize the entry of moisture into the system.
c: Use the specified lubrication oil from a sealed container only. Containers must be re-sealed immediately after dispensing the lubrication oil. Lubrication oil in containers which are not
properly sealed will become moisture saturated, and such lubrication oil is no longer suitable
for use and should be properly disposed of.
d: 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 HFC-134a (R-134a)
system. If accidental system discharge occurs, ventilate work area before resuming service.
Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
e: Do not allow lubrication oil (Nissan A/C System Oil Type S or Type R) to come in contact with styrofoam parts. Damage may result.
General Refrigerant Precautions
WARNING:
I Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
I Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
I Do not store or heat refrigerant containers above 52ÉC (125ÉF).
I Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
I Do not drop, puncture, or incinerate refrigerant containers.
I Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
I Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
I Do not introduce compressed air to any refrigerant container or refrigerant component.
