REMOVE THE 4x SCREWS ON THE BALLAST



THIS IS THE BALLAST EXPOSED, GLASS BULB WILL COME OFF TOGETHER




THE TUBE WILL NEED TO BE TWISTED IN ORDER TO BE REMOVED TO EXPOSE BULB





IT IS NOT ALIGNED, MEANING IT CAN BE REMOVED UPWARDS




BULB CAN NOW BE REMOVED FOR REPLACEMENT




TO TEST IF IT COMES ON, PLACE AND TWIST TUBE BACK INTO UNIT TO MAKE SURE IT FLIPS ON




IF BULB DOES NOT TURN ON, MAKE SURE THAT THIS METAL SENSOR IN THE MIDDLE IS ACTUALLY BEING PRESSED. YOU CAN HEAR A "CLICK" WHEN THE TUBE IS TIGHTLY SECURED INTO THE UNIT. IF IT DOES NOT CLICK INTO PLACE THE UV LIGHT WILL NOT TURN ON. 






THIS PLASTIC PIECE IN THE MIDDLE IS WHAT CLICKS THE SENSOR TO TURN LIGHT ON. MAKE SURE THAT YOU CAN HEAR A CLICK WHEN THIS IS INSERTED DOWN AND TWISTED TO LOCK INTO PLACE.






YOU CAN SEE THIS PIECE INSERT INTO THE SENSOR AND THIS IS WHERE IT WILL CLICK INTO PLACE.
