The total capacity of the oil tank B is 2 ounces and approximately 56 grams. 2. The end of the oil cylinder is a threaded core at the top of the 1/4 SAE thread. 3. The C part of the oil cylinder is a switch ball valve, and the handle can be switched. 4. The D end of the oil cylinder is internally threaded 1/4SAE with a top core and seal Use the filling method 1. Unscrew the A and B threads counterclockwise, add the appropriate cooling oil or fluorescing agent to B, and then tighten the A and B threads. The C ball valve should be closed. 2. Connect the D terminal to the low-voltage end of the air conditioning or cooling system that is not turned on. 3. Keep the cylinder vertical on the ground. The C ball valve opens slowly, allowing the refrigerant pressure in the system to flush to the A end. 4. Quickly close the valve core on the A end and return to the position immediately. At this time, the Oil Dye Injector is in the mixed state of the refrigerant and the oil. 5. Turn on the air conditioning or refrigeration system and the liquid in Oil Dye Injector will be drawn into the system. The refrigeration system can be switched twice to completely inhale the liquid in Oil Dye Injector. 6. If the customer suspects that the switch refrigeration is not fully integrated, a little refrigerant can be added from the A end to bring the liquid in the Oil Dye Injector cartridge into the system. 7. Close the C ball valve and remove the D end threads that are connected to the low pressure port of the refrigerant.Specification: --Thread size:Malel 1/4 SAE,Female 1/4 SAE. --Barrel capacity:2 OZ --Pipe working pressure:600PSI－3000PSI Package List: 1 x A/C Oil Injector If you have any question, please contact us.
