Room Terminator & Sound Attenuating
Tubing Installation
Room terminators and pre-assembled sound attenuating
tubes are provided in the Installation Kits.
NOTICE: Do not install terminators in a wall in
which a sharp bend in the sound attenuating tube is
required (see Figure 2.17). The result would be
unacceptable noise
..
OPTION: Using a SpacePak Kwik Connect Wall Elbow
(Model Number: AC-KCWE) addresses this condition
(see Figure 2.18).
In marking location for room terminator (see Figure
2.19), the center of the terminator should be
approximately 5" from the wall or, when installed in the
corner of a room 5" from both walls.
After marking location, drill a 1 ⁄
8
" diameter hole for outlet.
Verify there is at least 2" for tubing assembly clearance
all around this hole by visual inspection or inserting a
bent piece of wire to feel for obstructions. Adjust direction
of hole as needed, to gain this 2" clearance. After all
clearances have been checked, take a 4" diameter
rotary-type hole saw and cut a hole, using the
1 ⁄
8
"
diameter hole as a pilot.
Assemble spring clips to terminator plate with screws
provided in installation kit. Tighten clips until they are
close to the thickness of the material they are being
mounted to.
Assemble the room terminator to the sound attenuating
tubing by simply fitting the two pieces together and
twisting until tight (see Figure 2.20). If the terminator is to
be used in a floor location, then field fabricate a small
screen (1
1 ⁄
2
" square; 1 ⁄
4
x 1 ⁄
4
20-gauge galvanized wire
screen) and place screen over opening on the back of the
terminator prior to twisting on the kwik-connect (on the
sound attenuating tube).
NOTICE: Do not shorten sound attenuating tube
length. The result would be unacceptable noise.
Push the free end of the sound attenuating tube through
the 4" hole until the two toggle springs on the room ter-
minator snap into place.
Center the two spring clips on a line parallel to the
direction of the tubing routing from the room terminator
(see Figure 2.20). This is important since the weight of
the tubing will have a tendency to cause a part of the
terminator to pull away from the ceiling if the clips and
tubing do not run parallel.
Then tighten the screws (attached to the terminator) until
the terminator is snug against the ceiling or floor.
Do
not overtighten. For installations with floors or ceilings
which are thicker than normal, longer toggle screws or
special mounting plates may be required.
