INSTALLATION TIPS

READ CAREFULLY BEFORE BEGINNING SYSTEM INSTALLATION !
  • Read instructions carefully before starting and follow the proper sequence.
  • Check condition of engine mounts. Excessive engine movement can damage hoses to a/c, heater, radiator, transmission cooler and power steering systems.
  • Check vehicle interior electrical functions such as interior lights, radio, horn, etc, before starting. When ready to start installation, disconnect battery.
  • Fittings. Use one or two drops of the proper lubricant on O-rings, threads and O-ring BEAD where female nut rides. DO NOT use thread tape or sealants.
  • Always use two wrenches to tighten fittings. Try holding in one hand and squeezing together while other hand holds fitting in position. Do not over torque fittings.
SYSTEM CHARGING TIPS & WARNINGS

READ CAREFULLY BEFORE INSTALLING COMPRESSOR!
Failure to observe the following basic service notes may damage this unit and VOID WARRANTY!
  • Flush any components in the system to be reused to avoid contamination.
  • Replace or rebuild receiver-drier or accumulator when replacing compressor.
  • Manually turn compressor shaft (not pulley) a minimum of 10 times to clear oil from compressor head.
  • Evacuate system for a minimum of 30 minutes before charging. Longer if possible.
  • DO NOT ADD OIL! All compressors come with a full system charge of oil. All new and rebuilt compressors purchased from CAA contain oil that is compatible with R12 and 134a, unless otherwise noted on your invoice.
  • All custom rebuilt compressors contain mineral oil, which is compatible with R12 ONLY, unless otherwise specified on your invoice. Confirm this BEFORE attempting to charge your system with 134a.
  • DO NOT CHARGE SYSTEM WITH LIQUID WHILE THE ENGINE IS RUNNING !
    Do not tilt, shake or turn refrigerant can upside-down OR use a charging station to install refrigerant while the engine is running. Doing so will direct liquid refrigerant into the compressor piston chamber, causing damage to reed valves and/or pistons and/or other components, as well as potentially seizing the compressor. All warranty claims are voided as a result. NOTE: If charging with refrigerant in a liquid form, the engine must be off; you must allow a minimum of 30 minutes for liquid to "boil off" and you must hand turn the compressor hub (not the pulley) a minimum of 15 complete revolutions prior to starting the engine with the clutch engaged.
SPECIAL NOTES:
  • Slight leakage around the shaft seal is normal until the compressor has "run in" for six to eight operating hours.
  • Chrysler RV2 compressors do not include EPR valves. Re-use original valve if functioning properly, or install a new valve.
