Operating Instructions for Filling Cylinder with Three-color Tube and Double-meter Valve
Filling cylinder, three-color tube, quick connector, refrigerant
1. Close the ball valve of the filling cylinder, open the lid on the top of the filling cylinder and pour in the refrigerating oil
2. Connect the blue pipe joint of the double-meter valve three-color tube to the top thread of the filling cylinder and tighten it to ensure sealing.
3. Connect the yellow tube connector with the bottle opener to a bottle of refrigerant (Note: Do not pierce the bottle opener thimble through the refrigerant)
The red tube of the three-color tube is not used during this operation, so it is necessary to close the red valve of the double meter valve and open the blue valve
4. Connect the quick connector to the pipe joint of the filling cylinder
5. Start the car engine and turn on the AC switch of the air conditioner, and turn on the blower to the maximum
6. Connect the quick connector end of the filling cylinder to the low pressure port of the car air conditioner
7. Open the ball valve of the filling cylinder (the refrigerating oil replenishment bottle is kept vertical) to exhaust at the connection between the bottle opener and the yellow pipe,
Remember to loosen the interface slowly, slowly exhaust the air in the pipe, and tighten the bottle opener and the yellow tube when the exhaust is completed.
8. Open the refrigerant bottle to fill the refrigerant normally, and remove the pipe after the filling is completed.
