need help with new co2 canister

Hi Everyone.
Im ready to switch over from my old co2 canister to the new one. I received the new one a few weeks back and didnt pay much attention to it until today when the old one ran out.. The problem Im having is I know how to disconnect the old one from the regulator but have no idea how Im supposed to connect the new one when it has a turner on the top when the old canister just a place to place the reg. Here are a cpl of pix hopefully that will help you figure what Im trying to say. The new canister is the aluminum one.
thanks
patrick

The regulator attaches to teh valve opening on the right side of your picture.

remove the blue adapter from the regulator to screw it on.

Unlike the paintball tank, the valve on top can open and close the tank.

The regulator will be mounted 90 degrees from the current setup (horizontal vs. vertical). The new cylinder should have come with a nylon or compressed paper washer. If it didn't, you should be able to use the old one - just make sure you torque the heck out of the nut. Make sure the working pressure (if the reg is not preset) is at zero (the knob on the front of the regulator should be turned all the way COUNTER-CLOCKWISE). open the valve on the cylinder *slowly* plug in the solenoid, and begin slowly increasing working pressure (turning the regulator knob CLOCKWISE).

And if all you're asking for is how to physically connect the new cylinder, then mach is correct - just remove the blue adapter, make sure there's a washer in place, and crank down on it.

Doesn't have to be all the way. A single full turn should have the same effect. But it doesn't matter.

working pressure ~40psi seems very high

you would turn the dial on your regulator (most likely counter CW) until the pressure falls

probably to the 15-20psi range...unless you have one of those atomizers on your tank that say they need high working pressure

Thanks Optix
I really have no idea if it has a atomizer or not. How would I know? When my co2 comes on today I will try lowering it to see if that works.

how are you diffusing water into your tank?

typical diffusers look like:


typical atomizers looks like:


...if that helps

atomizers make micro bubbles that make the water look smoky or like club soda

because the pores in the ceramic stones are significantly smaller, they need a hgher working pressure

Does the regulator have a knob on it to adjust working pressure? Some do not and the working pressure would be "fixed" ie...not adjustable.

When you say knob on top, if it's the one on the gas cylinder itself, you don't adjust working pressure with that one.
