Precautions For Refrigerant System ServiceINFOID:0000000012431987
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, refe r 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 equi pment and Refrigerant Identifier.
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
Compressor malfunction is likely to occur if oil other than that specified is used.
• The specified HFC-134a (R-134a) oi l rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
- Cap (seal) the component immediately to minimize the entry of moisture from the atmosphere when removing refrigerant components from a vehicle.
- Do not remove the caps (unseal) unti l just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refr igerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified oil from a sealed container. Reseal containers of oil immediately. Oil becomes
moisture saturated and should no t be used without proper sealing.
- Do not allow oil to come in contact with styrene foam parts. Damage may result.
GENERAL REFRIGERANT PRECAUTION
WARNING:
• Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) from the A/C system, usin g certified service equipment meeting require-
ments of SAE J-2210 [HFC-134a (R-134a) recycling equipment] or J-2209 [HFC-134a (R-134a) recov-
ery equipment]. Ventilate work area before resumi ng service if accidental system discharge occurs.
Additional health and safety in formation may be obtained from refrigerant and oil manufacturers.
• Do not release refrigerant into the air. Use ap proved recovery/recycling recharging equipment to
capture the refrigerant each time an air conditioning system is discharged.
• Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
• Do not store or heat refrigerant containers above 52 °C (126° F).
• Do not heat a refrigerant containe r with an open flame; Place the bottom of the container in a warm
pail of water if container warming is required.
• Do not intentionally drop, puncture or incinerate refrigerant containers.
• Do not refrigerant away from op en flames; poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen; therefore be certain to work in well ventilated areas to prevent suffo- cation.
• Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing 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 heal th and safety information may be obtained from refrigerant manu-
facturers.

WARNING:
Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loo sen 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 as it is when mounted on the vehicle when the compressor is removed. Fail- ure to do so will cause oil to enter the low-pressure chamber.
• Always use a torque wrench and a back-up wrench when connecting tubes.
• Immediately plug all openings to prevent entry of dust and moisture after disconnecting tubes.
• Connect the pipes at the final stag e of the operation when installing an air conditioner in the vehicle.
Do not remove the seal caps of pipes and other comp onents until just before required for connec-
tion.
• 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 moisture thoroughly from the refriger ation system before charging the refrigerant.
• Do not reuse O-rings.
• Apply oil to circle of the O-rings shown in illust ration when connecting tube. Be careful not to apply
oil to threaded portion.
• O-ring must be closely attached to the groove portion of tube.
• Be careful not 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.
• Perform leak test and make sure that there are no leaks from connections after connecting line. Dis-
connect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten
connections of seal seat to the specified torque.
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 refri gerant could damage service equipment and refrigerant sup-
ply.
• Suggest the customer return the vehicle to the locati on of previous service where the contamination may
have occurred.
• In case of repairing, recover the refrigerant using only dedicated equipment and containers. Do not
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.

< PRECAUTION >
PRECAUTIONS
• The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-tomer Affairs for further assistance.
COMPRESSOR
CAUTION:
• Cap or plug all openings to prevent moisture and fo reign matter from entering.
• Store it in the same way as it is when moun ted on the car when the compressor is removed.
• Follow “Maintenance of Oil Level” exactly when replacing or repairing compressor. Refer to HA-22,
"Description".
• Keep friction surfaces between clut ch and pulley clean. Wipe it off by using a clean waste cloth
moistened with thinner if the su rface is contaminated with oil.
• Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This distributes oil e qually 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 norma l operation after replacing the compressor magnet
clutch.
LEAK DETECTION DYE
CAUTION:
• The A/C system contains a fluorescent leak detect ion dye used for locating refrigerant leaks. An
ultraviolet (UV) lamp is required to il luminate the dye when inspecting for leaks.
• Always wear 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 l eak detector (SST: J-41995).
The fluorescent dye leak detector sh ould be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leaks.
• Read and follow all manufacture’s operating inst ructions and precautions prior to performing the
work for the purpose of safet y and customer’s satisfaction.
• A compressor shaft seal should not necessarily be repaired becau se of dye seepage. The compres-
sor shaft seal should only be repaired after confi rming the leak with an electrical leak detector (SST:
J-41995).
• Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiag-
nosis during a future service.
• Do not allow dye to come into contact with painted body panels or interior components. Clean imme- diately with the approved dye cl eaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
• Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Do not 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. Do not 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 fo r three or more years unless a compressor malfunc-
tion occurs.
NOTE: Identification
• Vehicles with factory installed fluorescent dye have a green label.
• Vehicles without factory installed fluorescent dye have a blue label.

< PRECAUTION >
PRECAUTIONS
Do not attempt to connect HFC-134a (R-134a) service couplers to
the CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers
do not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. The hose fitting must be 1/
2 ″-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

• Illuminate pipe joints from different angles using UV lamp to check for leaks.
• Use a mirror in areas that are di fficult to see to check for leaks.
• Refrigerant leaks from the evaporator can be detected by soaking a cotton swab or similar material with
drain hose water and illuminating it using the UV lamp.
• Dust, dirt, and packing material adhesives used for condenser, evaporator, and other components may fluoresce. Be careful not to misidentify leaks.
5. Repair or replace parts where refrigerant lea ks occur and wipe off fluorescent leak detection dye.
NOTE:
Completely wipe off fluorescent leak detection dye from gaps between parts, screw threads, and other
components using a cotton swab or similar material.
6. Use a UV lamp to check that no fluorescent leak detection dye remains after finishing work. WARNING:
Do not look directly into UV lamp light source.
NOTE:
• For continuous operating time of UV lamp, fo llow the manufacturer’s operating instructions.
• Dust, dirt, and packing material adhesives used for condenser, evaporator, and other components may
fluoresce. Be careful not to misidentify leaks.
CHECK REFRIGERANT LEAKS USING ELECTRONIC LEAK DETECTOR
WARNING:
Do not check for refrigerant leaks while the engine is running.
CAUTION:
Be careful of the following items so that in accurate checks or misidentifications are avoided.
• Do not allow refrigerant vapor, shop chemical vapors, cigarette smoke or other contaminates around the vehicle.
• Always check refrigerant leaks in a low air flow en vironment so that refrigerant may not disperse.
1. Stop the engine.
2. Connect recovery/recycling/recharging equipment or manifold gauge set to the A/C service valves.
3. Check that A/C refrigerant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or more when temperature is 16 °C
(61 °F) or more. When pressure is lower than the specified value, recycle refrigerant completely and
recharge refrigerant to the specified level.
NOTE:
Leaks may not be detected if A/C refriger ant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or less when tem-
perature is less than 16° C (61°F).
4. Clean the area where the refrigerant leak check is performed and check for refrigerant leaks along all sur- faces of pipe connections and A/C system co mponents using electronic leak detector probe.
CAUTION:
• Continue checking once leaks are found. Always co ntinue and complete checking along all pipe
connections and A/C system comp onents for additional leaks.
• When leaks are detected, clean leak ar ea using compressed air and re-check.
• When checking the evaporator for leaks, always clean inside of drain hose so that the probe sur-
face may not be exposed to water or dirt.
NOTE:
• Always check for leaks starting from the high-pressure side and continue to the low-pressure side.
• When checking the evaporator for leaks, operate blower motor for 15 minut\
es or more at the maximum speed while the engine is stopped. Insert electronic leak detector probe into drain hose and hold for 10
minutes or more.
• When disconnecting shut-off valve that is connected to A/C service valve, always evacuate remaining
refrigerant so that misidentification can be avoided.
5. Repair or replace parts where refrigerant leaks occur.
6. Start the engine and set A/C control in the following conditions. • A/C switch: ON
