Figure 7. Universal Mounting System and Contour Seat
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 7.
NOTE: If your power chair is equipped with a Syn-
ergy Seat or a TRU-Balance Power Positioning Sys-
tem, refer to the information provided in separate
manuals.
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 7.
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 9 or 10.
WARNING! 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. Plug the controller connector into the rear of the
power base. See figure 3.
6. Secure the controller harness to the armrest
receiver with wire ties. See figure 10.
