Ballasting procedure

Dumb question - to gas ballast an Edwards rough pump can I simply open the ballast valve while the MS is pumped down? Or does the pump need to be isolated from the system?

Found this in the manual, looks like you can switch them with the pump running.
The past is there to guide us into the future, not to dwell in.
