Yes, I would just drain about a gallon out of it so that the level is below the head and the pressure is removed if there is any remaining. Then you will need to top it off when you replace it.

Here is a guide that will help with this:

Below is the info from the manual on this that will help getting it replaced. Let us know if there are questions. Thanks
