Tower Installation
The following procedure is described using a 16' (4877 mm) tall Diva Tower.
Taller towers are assembled using the same steps but may need to be spliced together.
Refer to the installation drawings.
Assemble the Tower Frame
1. Assemble the tower frame as shown.
a. Layout both the left and right hand vertical tower frames with the at side of each frame facing
toward the outside.
b. Position the lower cross brace with the weldment bar facing toward the top and align with the third set
of holes in the frames.
c. Position the upper cross braces to align with the next set of holes in the frames and then approximately
every 8' (2438 mm) thereafter.
d. Attach all of the cross braces to both tower frames using two 3/8-16 x 0.750 hex head capscrews
in each side.
The capscrews attach directly to a welded nut on the inside of the cross braces.
2. Set the tower frame assembly aside to attach later.

holding any protective paper to the face of the panels.
3. Cut foam strips to span the entire width of each upper center panel and install it to be fully recessed into
the bottom edge of the panel.
Then trim each foam strip end to a 45° angle.

of the frame as shown.
3. Align the frame assembly and the center panels: Proper alignment is critical!
a. Set the distance between the bottom of the lower center panel and the bottom of the frame assembly
to be 28-5/8" (727 mm) on both sides.
This is a critical measurement!
b. The seam between the center panels should be at the center of the middle xed hinge.
4. Attach the xed hinges to the center panels.
a. With the center panels in position and square to the tower frame using a 9/32" drill bit, drill a hole
through the inside panel surface only into each panel at each marked location.
Do not drill through the panel surface on the other side.
b. Clean away any wood shavings from drilling.
c. Attach the xed hinges to the center panels using 5/16-18 x 1" hex head tapping screws in the
sequence shown below.

any protective paper to the face of the panels.
Orient the panels so the part number label is at the bottom.
Steps 3 and 4 are for non-access door wing panels only!
Wing panels that are access doors already have foam strips installed in the panels.
Wing panels that are not access doors will require foam strips to be cut and installed between the panels.
3. Cut a foam strip to span the entire width of the upper center panel and install it to be fully recessed into
the bottom edge of the panel.
4. Connect the upper and lower wing panels together.
