Installation (continued)
Floor Frame and Door Frame Assembly (continued)
11. With the door frame in it's permanent location, check the door frame
to be sure that the vertical frame edges stand plumb to be able to
mate with the wall panels when they are installed.
12. If the door frame is not vertically plumb, carefully tilt
the assembly to allow access to the levelers.
a. Start with the levelers retracted as far as possible.
b. On the lowest corner, extend the leveler until the
door frame is level when resting on the floor.
If installing a double door, resume the procedure at this point
after the door frame has been assembled according to
the instructions in 270A837.
13. Connect the floor frame pieces together according to the
layout plan drawing using a floor frame connect bracket and
gasket at every location that two floor frame pieces meet end-to-end.
IMPORTANT: To properly seal the frame to the floor, each floor rail gasket must
protrude beyond the bottom of the floor rail channel by a minimum of 1/4" (6 mm).
Positioning each leveling screw in the floor frame to be 3/16" (5 mm) or approximately
3 turns above the threaded insert heads is a good starting point.
The bottom of the floor rail channel must remain at least 1/4" (6 mm) above the host floor.
Allowing the floor rail channel to contact the floor can result in insufficient floor rail gasket
compression and reduced acoustical performance.
a. The floor frame piece is set over the top of the previously installed gasket.
b. Straddle a floor frame connect bracket on the underside of two adjoining
floor frame pieces with the four pre-drilled holes aligned.
c. Thread two ¼-20 x 0.59 machine screws through each side of a
floor frame piece and into the connect bracket as shown.
d. Apply a self adhesive gasket straddled evenly
over the top of each floor frame side
and floor frame connect bracket.
IMPORTANT: The foam padding at the
bottom of the floor frame pieces must
all lay flat on the floor and not bowed up
to ensure proper fit and to prevent sound leaks.
