Precautions For Refrigerant System Service
INFOID:0000000011006046
GENERAL REFRIGERANT PRECAUTION
WARNING:
• Never breathe A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting
requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a)
recovery equipment]. Ventilate work area before resuming service if accidental system discharge
occurs. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
• Never release refrigerant into the air. Use approved recovery/recycling recharging equipment to cap-
ture the refrigerant each time an air conditioning system is discharged.
• Wear always eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
• Never store or heat refrigerant containers above 52
°
C (126
°
F).
• Never heat a refrigerant container with an open flame; Place the bottom of the container in a warm
pail of water if container warming is required.
• Never intentionally drop, puncture, or incinerate refrigerant containers.
• Keep refrigerant away from open flames: poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-
cation.
• Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
WORKING WITH HFC-134a (R-134a)
CAUTION:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal-
function is likely to occur if the refrigerants are mixed, refer to “CONTAMINATED REFRIGERANT”
below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger-
ant recovery/recycling recharging equipment and Refrigerant Identifier.

• Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. Compressor malfunction is likely to occur if lubricant other than that specified is used.
• The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
- Cap (seal) immediately the component to minimize the entry of moisture from the atmosphere when
removing refrigerant components from a vehicle.
- Never remove the caps (unseal) until just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refrigerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified lubricant from a sealed container. Reseal immediately containers of lubricant.
Lubricant becomes moisture saturated and should not be used without proper sealing.
- Never allow lubricant to come in contact with styrene foam parts. Damage may result.
CONTAMINATED REFRIGERANT
Take appropriate steps shown below if a refrigerant other than pure HFC-134a (R-134a) is identified in
a vehicle:
• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into
the atmosphere.
• Explain that recovery of the contaminated refrigerant could damage service equipment and refrigerant sup-
ply.
• Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
• In case of repairing, recover the refrigerant using only dedicated equipment and containers. Never
recover contaminated refrigerant into the existing service equipment. Contact a local refrigerant prod-
uct retailer for available service if the facility does not have dedicated recovery equipment. This refrigerant
must be disposed of in accordance with all federal and local regulations. In addition, replacement of all
refrigerant system components on the vehicle is recommended.
• The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-
tomer Affairs for further assistance.
REFRIGERANT CONNECTION
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
• Expansion valve to evaporator
• Refrigerant pressure sensor to condenser
WARNING:
Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
Observe the following when replacing or cleaning refrigerant cycle components.
• Store it in the same way at it is when mounted on the car when the compressor is removed. Failure
to do so will cause lubricant to enter the low-pressure chamber.
• Use always a torque wrench and a back-up wrench when connecting tubes.
• Plug immediately all openings to prevent entry of dust and moisture after disconnecting tubes.
• Connect the pipes at the final stage of the operation when installing an air conditioner in the vehicle.
Never remove the seal caps of pipes and other components until just before required for connection.
• Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
• Remove thoroughly moisture from the refrigeration system before charging the refrigerant.
• Replace always used O-rings.
• Apply lubricant to circle of the O-rings shown in illustration when connecting tube. Be careful not to
apply lubricant to threaded portion.
• O-ring must be closely attached to the groove portion of tube.
• Never to damage O-ring and tube when replacing the O-ring.
• Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is
installed to tube correctly.
HA-98
< PRECAUTION >
[QR25DE]
PRECAUTIONS
• Perform leakage test and make sure that there is no leakage from connections after connecting line.
Disconnect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten
connections of seal seat to the specified torque.
COMPRESSOR
CAUTION:
• Plug all openings to prevent moisture and foreign matter from entering.
• Store it in the same way at it is when mounted on the car when the compressor is removed.
• Follow “Maintenance of Lubricant Quantity in Compressor” exactly when replacing or repairing
compressor. Refer to
• Keep friction surfaces between clutch and pulley clean. Wipe it off by using a clean waste cloth
moistened with thinner if the surface is contaminated with lubricant.
• Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This distributes equally lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.
• Apply voltage to the new one and check for normal operation after replacing the compressor magnet
clutch.
LEAK DETECTION DYE
CAUTION:
• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An
ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages.
• Wear always fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995).
The fluorescent dye leak detector should be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leakages.
• Read and follow all manufacture’s operating instructions and precautions prior to performing the
work for the purpose of safety and customer’s satisfaction.
• A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-
sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector
(SST: J-41995).
• Remove always any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during a future service.
• Never allow dye to come into contact with painted body panels or interior components. Clean imme-
diately with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
• Never spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Never use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system.
• Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Never use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system, or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system, or A/C system damage may result.
• The fluorescent properties of the dye remains for three or more years unless a compressor malfunc-
tion occurs.
