Recovery Station Dye Injector Tool with a Charged System
The R134a dye injector tool is designed to be used
with the OEM1415 recycling station.
1. Disconnect the low pressure hose (blue) from the
1/2 inch Acme flare fitting on the rear of the
station.
2. Connect the dye injector to the fitting.
3. Connect the low pressure hose to the dye
injector.
NOTE: The dye injector can be permanently
mounted on the recycling station with the two
threaded holes on the bottom of the reservoir.
4. Open the valves on either side of the reservoir on
the dye injector.
5. Recover 0.5 lb. (0.23 kg.) of refrigerant from the
system. This amount of refrigerant will act as a
carrier to inject the dye.
6. Close the valve on the tractor side of the dye
injector and continue to recover. This will draw
the refrigerant out of the reservoir on the dye
injector.
7. Close the valve on the station side of the dye
injector and stop recovering.
8. Remove the cap from the reservoir and fill the
reser voir with the contents of one bottle of
fluores cent dye. Reins tall the cap on the
reservoir and tighten securely.
9. Open the valve on tractor side of the reservoir on
the dye injector.
10. Recharge the A/C system with the proper
amount of refrigerant removed earlier - 0.5 lb.
(0.23 kg.). Start the recharging process and
immediately open the valve on the station side of
the dye injector to prevent drawing the dye into
the charging station. The dye will be injected into
the system while recharging.
11. Install the dye identification sticker on a clearly
visible area on the compressor body close to the
service ports. This will alert service personnel in
the future to the presence of the dye in the
system.

12. Operate the A/C system for about 15 minutes to
circulate the dye throughout the system. Turn off
the system and use the UV lamp and goggles to
locate leaks. The exact location of the leak will be
shown by a bright yellow/green glow of the dye.
NOTE: The operating time needed for the dye to
penetrate a leak and show will depend on the size of
the leak. A very small leak could take hours or days
of system operation to appear.
13. After repairing the system, use fluorescent dye
cleaner to remove any traces of dye from around
the leak location to avoid false diagnosis in the
future.
