The mechanical installation involves a sub-base mounting system designed to facilitate easy maintenance. The sub-base should be leveled meticulously—not only for aesthetic appeal but to ensure that gravity-based components or internal level-sensitive sensors operate correctly. Once the sub-base is secured using appropriate wall anchors, the 33TBAC01 controller "snaps" into place, establishing electrical contact with the pins on the sub-base. Installers must verify that the connection is flush to maintain the low air-leak performance required by high-efficiency standards. Following the physical installation, the manual emphasizes a
