Seat Installation

It may be necessary to install the seat either prior to initial oper- ation 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 alumi- num extrusions mounted to the seat base. These extrusions attach to the power seat frame (see figure 11) or to a pair of trapeze bars that are mounted to the power base (see figure 12).

NOTE: If your power chair is equipped with a Synergy Seat or a TRU-Balance Power Positioning System, 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.Raise the power elevating seat actuator up 2 in. (5 cm) to allow for sufficient clearance.

2.Tilt the seat back and slide the rear extrusion onto the power seat frame or rear trapeze bar.

3.Lower the front extrusion onto the power seat frame or front trapeze bar until the seat locks into place.

4.Flip the seat latch safety down. See figure 11.

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. “Com- fort Adjustments”.

6.Loosen the rear shroud fasteners and remove the rear shroud.

7.Route the controller connector to the back of the power base and secure the controller harness to the armrest receiver with wire ties. See figure 13 or 14.

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 the controller harness to prevent the harness from getting caught in the drive tires, pinched in the seat frame, or damaged when passing through doorways.

8.Plug the controller connectors into the power module and connect the battery connector. See figure 7.

9.Reinstall the rear shroud and tighten the fasteners.
