Instructions for use：

Before the inflation process, please put your small soda cylinders in the freezer to cool, Ensure that the small cylinder can flush more carbon dioxide.

1. Confirm the On/Off valve (A)and the release valve(C) are closed(90° position), rotating the pin switch(B) of small cylinder to the top(anticlockwise).

2. Connect the fill station connector(A) to the big CO2 bottle. (Place the gasket in the connector of the filling adapter.Use the wrench to tighten it, if your big Co2 tank don’t have siphon inside, you need to place the big Co2 tank upside down or

    on its side. )

3. Connect the small cylinder to the soda Co2 adapter(B).

4. Rotate the pin switch(B) of the adapter to the bottom(clockwise).

5. Open the big Co2 air tank’s valve.

6. Open the On/Off valve(A) slowly, and close it after 2-3 seconds, and then open the release valve(C) to exaust the excess air inside the small cylinder, and then remember to close the release valve(C) after this step.

7. Open the On/Off valve(A) slowly again to do the inflation process, and last for 25-30 seconds, then close the On/Off valve(A) and the big Co2 tank’s valve.

Precautions：

If the inflation cannot be completed, Please check if there are several situations as below.

1. Whether the product is not suitable: You need to check that the inlet thread and outlet thread of the inflatable adapter meet your needs. The inlet thread needs to be CGA-320 (G1/2) for US and Canada only. The inlet thread should be TR21-4, and the compatible models include but not limited to FIZZI/ONE TOUCH/JET blue cyclinders, but paintball tanks and TERRA/ART/DUO/GAIA pink cyclinders are not compatible.

2. Whether the temperature of the cyclinders is high or not: We generally recommend customers to freeze the cyclinders before filling, so as to have a better filling effect. During the inflation process, the air pressure inside the bottle will increase and the gas will be more and more difficult to rush in, cooling the bottle is an effective way to help reduce the air pressure.

3. Whether it is because of air leakage: You can check two main places, which are the parts linked with the big and small cylinders. Check to see if the gasket is fitted and the pin switch are tightened. If the product is broken, please contact usto deal with it for you.
