Seat Installation
It may be necessary to install the seat either prior to initial operation or after transporting your power chair. Contour seats are attached to the power base with the Universal Mounting System (UMS). The UMS con- sists of universal parts that may be attached to the seat, regardless of seat width or seat depth. The two main components are aluminum extrusions mounted to the seat base. These extrusions attach to a pair of trapeze bars that are mounted to the power base. See figure 11.
NOTE: If your power chair is equipped with a Spe- cialty Seat, Synergy Seat, or a
WARNING! Do not pick up the seat frame by the armrests. They are free to pivot, and you may lose control of the seat if they do so.
To install the seat:
1.Tilt the seat back and slide the rear extrusion onto the rear trapeze bar. See figure 11.
2.Lower the front extrusion onto the front trapeze bar until the seat locks into place.
3.Flip the seat latch safety down.
WARNING! Make sure the seat latch safety is flipped down before using your power chair.

4.Install the controller and route the harness to the back of the power base. See figures 12 and 13.
MANDATORY! Prevent controller harness damage! Avoid routing the controller harness on the outside of the armrest pad. Route the harness under the armrest or toward the inside of the armrest pad. Use correct tie- down points for controller harness to prevent the harness from getting caught in the drive tires, pinched in the seat frame, or damaged when passing through doorways.
5.Loosen the rear shroud fasteners and remove the rear shroud. See figure 6.
6.Plug the controller connector into the power base. See figure 7.
7.Replace the rear shroud and tighten the rear shroud fasteners. See figure 6.
8.Secure the controller harness to the armrest receiver with wire ties. See figure 13.
