Should you unplug and turn off pump before you start?

Hi does the security screw for the quarts sleeve have to go in-between the 2 plastic gaps to lock it I have noticed in one of your other videos its shows it does but on this one it's not, I am asking as on my filter it will not turn and go to this position lock it in thanks

Jeff, you really should let Manny do all the talking. He clearly has a better idea of what he's doing than you.
