Refrigerant: Service and Repair
Heating, Ventilation and Air Conditioning
REFRIGERANT RECOVERY AND RECHARGING
TOOLS REQUIRED
-
J 39500-B A/C Refrigerant Recovery, Recycling and Recharging (ACR4) System
-
J 41870 Pureguard 2
-
J 41810-100A High Intensity Black Light
CAUTION:
-
Refer to Breathing R-134a Caution in Service Precautions.
-
For personal protection, goggles and gloves should be worn and a clean cloth wrapped around fittings, valves, and connections when
doing work that includes opening the refrigerant system. If R-134a comes in contact with any part of the body severe frostbite and
personal injury can result. The exposed area should be flushed immediately with cold water and prompt medical help should be obtained.
NOTE:
-
R-134a is the only approved refrigerant for use in this vehicle. The use of any other refrigerant may result in poor system performance or
component failure.
-
To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
-
Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity
mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
-
R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, as they are incompatible with each other. If the
refrigerants are mixed, compressor failure is likely to occur. Refer to the manufacturer instructions included with the service equipment before
servicing.
The J 39500-B removes the Refrigerant-134a from the vehicle's A/C system. The recovery procedure uses one filtering cycle. The evacuation procedure
uses an automatic multiple pass filtering cycle. These filtering cycles ensure a constant supply of clean, dry refrigerant for A/C system charging.
The Initial Set-Up Instruction Manual, provided with the J 39500-B, contains specific procedures for proper recovery, evacuation and recharging.
