How to remove electronic actuator from manifold valve?

[cnknudson]

I am trying to figure out how to remove the electronic actuator (22C 24NC4) from the manifold valve assembly so that I can open the valve to pressure check the zone piping installation; I have been told that the actuator has to be removed so that the valve can be manually manipulated for testing purposes during installation.  Is there an instruction manual showing how to remove and re-install the actuator?

I have not seen any instructions but all you need to do is un-screw the metal ring at the base of the actuator from the manifold. Repeat the process to re-install. I have seen plumbers use channel locks on the ring without breaking it.
