A drying apparatus includes a body, an airflow inlet, a bar supported by the body, the bar including an airflow outlet, and at least one flow generator to receive inlet air from the airflow inlet and to expel forced airflow through the airflow outlet. At least one motor is provided to rotate the bar about an axis oriented substantially parallel to a drying face of the body, the rotation of the bar reorientating the airflow outlet.

A lifting column includes at least five column elements which are at least partly nested, and a first and a second drive arrangement. The first drive arrangement is configured to move the three innermost column elements relative to one another. The second drive arrangement is configured to move the three outermost column elements relative to one another.

An installation tool for mounting a display on a wall having a wall mount includes a first leg and a second leg disposed in parallel relationship with the first leg. A crossbar is slidably connected to the first leg and the second leg. A holder is configured to accept the display, the holder slidably connected to the first leg and the second leg. A threaded rod includes a connector for engaging the cross bar. A lifter is configured to lift the holder, the lifter positionable along the threaded rod. The display if installed in the installation tool and lifted to a vertical position where it can be connected to the wall mount.
