lIf the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN
Customer Affairs for further assistance.
General Refrigerant PrecautionsEJS00628
WARNING:
lDo not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
lAlways wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
lDo not store or heat refrigerant containers above 52°C.
lDo 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.
lDo not intentionally drop, puncture, or incinerate refrigerant containers.
lKeep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
lRefrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
lDo not pressure test or leak 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.
Precautions for Refrigerant ConnectionEJS005FL
A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
lExpansion valve to cooling unit
lEvaporator pipes to evaporator (inside cooling unit)
lRefrigerant pressure sensor
ABOUT ONE-TOUCH JOINT
Description
lOne-touch joints are pipe joints which do not require tools during piping connection.
lUnlike conventional connection methods using union nuts and flanges, controlling tightening torque at
connection point is not necessary.
lWhen removing a pipe joint, use a disconnector.
