Placing Dye In A/C System
^ The Universal Connect Set and Tracer Stick Capsule are used to introduce dye into the Air Conditioning systems of vehicles which were produced with systems charged with R134a, without the need to discharge the refrigerant.^ Evacuate or purge the Universal Connect Set hose assembly. Close all valves finger tight, do not apply force or damage may be caused to the valve seat.
^ While holding the tracer stick capsule, (A, Illustration 1), vertically, so that the embossed arrow is pointing upwards, carefully remove the black screw cap and screw the capsule to the control valve, (B, Illustration 1), finger tight.
^ Turn the control valve and capsule assembly so that the embossed arrow is now pointing downwards. Remove the second black screw cap from the capsule and screw the service valve fitting, (C, Illustration 1), to the capsule, finger tight.
^ Connect the quick coupler, (D, Illustration 1), to the high side service port of the air-conditioning system.
^ Ensure that the control valve (B, Illustration 1) is closed.
^ Connect the service valve fitting, (C, Illustration 1), to the high side quick coupler on the manifold or the recovery unit.
Note:
Follow the recommended procedure of the refrigerant charging/recovery apparatus.
^ Open the control valve, (B, Illustration 1), and the line to the charging/recovery apparatus to allow refrigerant to flow through the capsule, carrying the UV fluorescent dye into the system.
^ After the dye has been flushed from the capsule, close the control valve and disconnect the connector set from the system and the charging/recovery apparatus.
^ Remove the service valve fitting, (C, Illustration 1), from the capsule and retain it.
^ Remove the capsule from the control valve, (B, Illustration 1), and discard it.
^ Using suitable disposable, clean material and the water-based Glo-Away Fluorescent Dye Cleaner/Remover, wipe the service valve fitting and the control valve to remove surplus dye and so avoid handling contamination.
^ Check, with a beam of ultraviolet light, that the dye has been removed.
^ When the system has been filled, the label, (Illustration 2), must be fixed to the radiator crossmember, in the position shown.
