Moving this equipment will require removing the doors in order to get it out of the room it is currently located in. Can the doors be removed easily with a philips and/or flat head screwdriver? Are there 3 bolts on the top and bottom of each side? Must I ensure the nuts stay in place so the springs don't pop off and make it more difficult to remount the doors? Thanks for your help. Must I download the manual for better instructions? M. West
