IV. ASSEMBLY
SEAT INSTALLATION
It may be necessary to install the seat either prior to initial operation or after transporting your power chair.
Most seats are attached to the power base with the Universal Mounting System (UMS). The UMS consists
of universal parts that may be attached to any medium-back or high-back 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. If your power chair is equipped with a
Synergy or TRU-Balance Seating System, refer to the installation instructions 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, resulting in personal injury or damage to the
chair.
To install the 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 figures 6 and 13.
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 14.
WARNING! Make sure the seat latch safety is flipped down before using your power chair.
5. Install the controller into one of the armrests. See V. Comfort Adjustments.
6. Route the cable to ensure that the cable cannot be pinched in the seat hinge.
7. Plug the controller cable into the connector on the electronics tray. See figure 7.
8. Secure the controller cable to the armrest receiver with one or more wire ties.
