Replace CO2 gas bottles

After performing the action of fire extinguishing, the gas bottle replacement indicator is solid on, indicating that you need to replace the gas bottles. You need to purchase new gas bottles for replacement.

💡 The CO2 gas bottles are not included.

1. Power off the fire safety set and unplug the USB cable before replacing CO2 gas bottles. Unplug the power cable and USB cable, then hold the middle part of the control box and remove the upper cover.

2. Rotate the CO2 gas bottles anticlockwise to remove them.

• If the closed processing space is no more than 0.065 cubic meters, you can choose to replace 2 or 4 gas bottles.

If you use 2 gas bottles, install them on a diagonal, for example, installing them on holes A, and then install two empty gas bottles on the other diagonal.

• If the closed processing space is more than 0.065 and no more than 0.13 cubic meters, you need to replace 4 gas bottles.

After replacing the gas bottles, you can connect the control box of the fire safety set to the power supply to use it.
