9 Install the reactor.
1) Pinch the grip of the slider vertically and slide it toward the right. Insert the reactor into its original position through the clearance created by sliding the slide out of the way.
When you release the grip of the slider, the slider holds the reactor in place with the force of the spring.
2) Check that the 10-mm diameter hole on the left side of the reactor is facing the round hole in the holding plate on the left side of the lamp at the same height.
