How to replace a Taco Cartridge Circulator

I have a Vaillant Boiler for my Baseboard Heating System. The pictures of the system can be found here:

The Taco cartridge circulator, model 007-F4, is not working, and I have ordered a new one to replace it. As I never did it before I would like to check here if the following steps will lead to a succesful work:

1. turn off power and let water cool down.
2. drain water through the manual valve below the circulation pump.
3. remove the old pump and replace with the new one.
4. fill water in again, to 15-20 psi.
5. turn on the power again and that should complete the task.

I still don't know how to make sure the water will drive out air when water was drained.

Thanks for any input!

Steps 1-thru-5 are correct.

Since you are going to empty your system, if you don't have a vent in at least one of the baseboards on the top floor, now will be a good time to do so.

Circulator

How do you know it's not working? Are you getting 120 volts to it?
If you got your pressure issue resolved, the system could be just air bound. Not trying to sound like a wise guy, just don't want to see you spend money you may not have to.
