Contour Seat Installation
The Universal Mounting System (UMS) consists of universal parts that may be used on any medium-back or high-
back seat, regardless of seat width or seat depth. The two main components are aluminum extrusions that are
mounted to the seat base. These extrusions attach to a pair of trapeze bars that are mounted to four steel towers.
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 a contour seat:
1. Set the trapeze bars to the desired height. To change the trapeze bar height, see V. "Comfort Adjustments."
2. Tilt the seat back and slide the rear extrusion onto the rear trapeze bar. See figure 12 and 12a.
3. Lower the front extrusion onto the front trapeze bar until the seat locks into place.
4. Flip the seat latch safety down. See figure 12.
WARNING! Make sure the seat latch safety is flipped down before using your power chair.
5. Install the controller into one of the armrests.
6. Plug the controller harness into the power base.
7. Route the harness to ensure that it cannot be pinched in the seat hinge. See firgure 13.
8. Secure the controller harness to the armrest receiver with one or more wire ties.
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.
