Just hook the air lines up the same as the old valve and activate the knob, worst that will happen is you will need to swap the lines at the valve that go to the cylinder.

You probably should adjust the muffler flow screws all the way in to start & back them out 1 turn at a time until you get movement.
then finer adjustments as desired.

BTW, one muffler is for extend & the other will be for retract
