IV. ASSEMBLY
Seat Installation
It may be necessary to install the seat either prior to initial operation
or after transporting your power chair. If your power chair is
equipped with a Synergy, Tru-Balance or Specialty seating sys-
tem, refer to the information provided in separate manuals. The
medium- and high-back seats are attached to the power base with
the Universal Mounting System (UMS). The UMS consists of
universal parts that may be attached to the seat, regardless of seat
width or seat depth. The two main components are aluminum ex-
trusions mounted to the seat base. These extrusions attach to a pair
of trapeze bars that are mounted to the power base. See figure 11.
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 figure 11.
3. Lower the front extrusion onto the front trapeze bar until
the seat locks into place.
4. Flip the seat latch safety down.
WARNING! Make sure the seat latch safety is flipped
down before using your power chair.
Controller Installation
Depending on the various configurations and options you have
chosen for your power chair, it may have been shipped with-
out the controller module installed in the armrest.
WARNING! Do not place the controller cable so
that it can be pinched in the seat frame or power
base frame.
1. Install the controller into the mounting block or under the armrest. See figure 15 or 16.
2. Tighten the setscrew(s).
3. Route the controller cable so that it cannot be pinched in the seat hinge.
4. Loosen the rear shroud fasteners and remove the rear shroud. See figure 6.
5. Plug the controller connector(s) into the power base. See figure 6.
6. Secure the controller cable to the armrest receiver with one or more wire ties.
7. Replace the rear shroud and tighten the rear shroud fasteners.
