6 Always use approved refrigerant recovery / recyclingequipment to capture refrigerant which is removed from the A/Csystem. Do not mix refrigerants in the same piece of equipment; one should be designated for R-12 andanother for Handling of RefrigerantAlways wear eye and hand protection when working on an A/C system or Compressor . Liquid refrigerantcan cause frostbite and / or VentilationKeep refrigerants and oils away from open flames. Refrigerants can produce poisonous gasses in thepresence of a flame. Work in a well-ventilated Avoid Use of Compressed AirDo not introduce compressed air into an A/C system due to the danger of Warranty for Recycled RefrigerantThe warranty offered by Sanden International ( ), Inc.

7 , on air conditioning compressors when usedwith recycled refrigerant will be the same as for new refrigerant provided that the following SAE standardsare met:R-12R134aRefrigerant PurityJ1990J2099 Recycling MachineJ1989J2210 Recycling machines must be validated to the appropriate SAE standard by Underwriters refrigerant from other sources must meet the appropriate ARI standards. Failure to comply withthese provisions may void any warranty on the R134a / PAG Oil Handling PrecautionsAs a conscientious member of the global community, Sanden Corporation with its subsidiaries iscommitted to the elimination of CFC-based refrigerants.

8 This manualfocuses on Service information forSanden compressors intended for use with R134a and PAG (Cont.)1. Always follow safety precautions described in Section Do not discharge R134a into the atmosphere. Even though its ozone depletion potential is zero, itdoes have global warming potential. Recovery and recycling are mandated by the Clean Air Act. Userecovery equipment designated only for R134a. Never introduce another refrigerant into the Never mix R134a with other refrigerants or A/C systems failure is likely to Use only Sanden specified PAG lubricants for R134a systems using Sanden compressors.

9 If otherlubricants are used, A/C system failure is likely to Never introduce R134a or PAG oil into a system not designed for them except when following theappropriate retrofit procedure described in Section The Sanden specified PAG oils used in R134a systems absorb atmospheric moisture very in the A/C system can cause major damage or failure. Never leave PAG oil exposed to air for a prolonged time. Tightly reseal the oil containerimmediately after each use. During A/C system repair, cap all fittings as soon as opened and leave capped until just beforethey are reconnected.

10 If a repair is performed on an R134a Compressor or system, evacuate the system for at least 45minutes before recharging to ensure the removal of moisture which may have been absorbed bythe PAG oil in the Compressor and Table of Saturation Temperatures and PressuresTemp.( F)Pressure (psig)Temp.( F)Pressure (psig)Temp.( F)Pressure (psig) in. in. in.
