3. Place the first 2 x 6 board on the subfloor so that it is positioned perpendicular to the
underlane track under the rail adapter plate. This is just an approximate location.
4. Place the other 2 x 6 x 18-inch board on the subfloor parallel to the first board with its
front edge 23.5 inches (59.7 cm) from the first board’s front edge (see Figure 3).

5. The Ball Lift assembly is shipped configured for 230-volt operation and, if necessary,
must be reconfigured for 115-volt operation. To configure the Ball Lift motor for 115-volt
operation, remove the motor’s electrical cover plate and reconnect the wiring for low
voltage operation as shown in the wiring diagram on the motor’s frame. Reinstall the
cover plate. Instructions for configuring the controller and the ball rack blower motor for
115 volts are provided later.
6. Lower the Ball Lift mechanism into the opening and onto the two 2 x 6’s.
Position
the Ball Lift in line with the underlane track so that the holes in the adapter plate on
the end of the underlane track align with the four studs on the Ball Lift base plate.
7. Center the 2 x 6 boards under the bolt holes in the Ball Lift base plate and check the
Ball Lift for level side to side and front to back. Use shims from the shim pack (610-
494-444), as necessary.
8. Measure the distance from the underside of the Ball Lift base plate to the top surface
of the approach. This distance should be 14-7/16 inches (36.7 cm). If necessary,
add or remove shims, plane the 2 x 6 boards, etc. Maintain the unit level side to
side and front to back.
