Unless you get other replies........

I am not familiar with the brand. But I have tackled manya faucet and by and large, if once you remove a nut that holds down the cartridge, generally they will just pull right out, with some force. I ususally stick the screw from the handle back in and clamp my vicegrips over the screw head and pull up. (Keep your face clear so you don't hit yourself if it suddenly comes loose!)

Moen brand employs another system where they have this tuning fork looking piece of flat brass (that you must pull out, horizxontally,) that actually is what keeps the cartridge in the faucet.

Just really inspect what you have and see if you can figure out what is the means by which the manufacturer keeps the cartridge from flying out of the hole when water pressure is on behind it. With that in mind, you shoud be able to see what has to come out to get out the cartridge. And like I said...if it appears just some large threaded piece was holding it down...then you would just pull up on the stem of the cartridge the way I described.

On cartridges, the stem is always allowed to move up and down and is never locked down with anything. What IS locked down is the stationary outer cylinder of the cartridge, and that is what you have to look for that has to be removed that holds that down.
