How does the gas filling machine operate?

Previous preparation: connection.

FM200 tank connects to filling machine

FM200 empty cylinder connects to filling machine

Nitrogen cylinder connects to filling machine

Nitrogen cylinder connects to the adapter on FM200 empty cylinder

First step, vacuum sucking.

Switch on the nitrogen cylinder just a little to open the valve of FM200 empty cylinder(control the switch to release nitrogen, like 10bar pressure enough to open the valve of FM200 empty cylinder)

Open the power of the filling machine

Switch on the controller to cylinder valve, F5

Switch on the controller to vacuum pump, F6

After the right gauge indicate the pressure inside cylinder is close to zero or a little lower than zero, then close F6.

Second step, FM200 filling.

Keep F5 open

Open the valve of FM200 tank by a spanner and switch on the controller to storage valve, F3(if you will continue to fill other cylinders, you can keep the valve of FM200 tank open still. but of course, it would be safer to close it.)

Then you will see the weight of FM200 empty cylinder will increase.(here we see digital scale)

You can close the valve of FM200 tank and shut off F3 till the weight reaches the figure that you want.

Third step, pressuring.

Keep F5 open

Open the cylinder valve of nitrogen and switch on the controller to nitrogen valve, F4

When the pressure reaches the figure that you want, it will send alarm.

You can just switch off the cylinder valve and F4

After that use nitrogen to switch off the valve of FM200 cylinder filled as the first step

Fourth step, pressure release.

After the work of filling, please do not disconnect all devices.

Open the controller F2 to release all gas inside the filling machine.

Then disconnect all devices safely.(actually there is a little gas existing inside the hose between nitrogen cylinder and filling machine. There is no harm to people. But you can also try to release the gas as the below operation

Disconnect the hose connecting to FM200 cylinder filled. Just open F4 but keep the valve of nitrogen cylinder closed. Then all the gas will be released. And it is the safest to disconnect all other devices. )
