11.After installing the lift, use the test push button to carefully operate the lift all the way up and down to be sure the clear- ances are adequate. Be prepared to stop the lift immediately if the lift begins to sound labored or if one side or the other side begins to travel slower.

12.To maintain plenum rating, seal any openings in the lift hous- ing (except joist tabs) using foil tape.

Installation in a Wood Framework (or Side-Mounted to Joists)

A suitable framework must be constructed to support the lift in the ceiling. Refer to for dimensions of the lift. The lift housing has mounting tabs to assist in side-mounting the lift to the ceiling joists or otherwise securing it to a wood framework.

The ideal lift installation time is after the sheetrock has been installed, but before the sheetrock has been mudded or finished.

1.Remove the closure panel from the bottom of the lift to gain access to the front and back mounting holes.

CAUTION: For smooth and reliable operation, the lift must be installed square and parallel in all dimensions. Avoid stressing the lift at any time during installation.

2. Position the lift in the desired location, making sure the unit is level, square, parallel and there is no stress applied to the box (chassis).

3. Secure the lift to the joists or wood framework. Drive at least six 1/4 x1-1/4-in. lag screws through the mounting tabs around the inside of the lift housing and mounting holes across the back of the lift. There are 8 tab locations, three in each side and two in one end, and 3 mounting hole locations across the back

of the lift (see Figure 6 and Figure 7). The lift requires support on two opposing sides only.

4.After installing the lift, use the test push button to carefully operate the lift all the way up and down to be sure the clear- ances are adequate. Be prepared to stop the lift immediately if the lift begins to sound labored or if one side or the other side begins to travel slower.

5.To maintain plenum rating, seal any openings in the lift hous- ing (except joist tabs) using foil tape.

The bottom of the lift may be painted or textured as necessary to match the ceiling.
