Installation (cont.)
SUSPENDED CEILINGS:
1. Remove the ceiling tile from the ceiling grid. Cut a 14-1/4" circular hole in the ceil-
ing tile. Use the included template as a guide.
2. Put the CSUB face down on a workbench or on the floor without grille
installed.
3. Place the ceiling tile over the CSUB, making
sure the ceiling tile is facing out. It is
important to note the direction of the
clamps: they must be installed so that they
span the distance from one side of the
ceiling tile to the other (approx. 24", see
illustration at right). The front of the
CSUB is engraved with guide arrows
for “24-Inch Ceiling Tile” (see
Product Diagrams section). Use these
guides for this installation.
4. Using an electric powered screwdriver with
the clutch at a low setting, tighten each
screw until the clamps are just snug
against the tile surface. The CSUB’s clamps
can be tightened from either the front or
rear of the speaker. Use a No. 3 Phillips screwdriver when working from the
front. Use a 1/4" flat-blade screwdriver when working from the rear. If working
from the rear of the speaker, the screws tighten COUNTERCLOCKWISE.
Do not over-tighten clamps. Once all four clamps are properly positioned and
snug on the ceiling tile, the assembly (CSUB and ceiling tile) is ready to be
mounted in the ceiling grid.
5. Before installing the grille, make sure you have selected the proper power setting
on the front panel rotary switch. Refer to the Selecting Power Levels section for
instructions on selecting the power level. Install the grille as indicated in the
Speaker Grille Installation & Removal section.
6. Before mounting the CSUB/tile assembly, make sure the snap-lock input connector
has been connected to the input wires (see Speaker Wiring section). The
CSUB/tile assembly may now be placed in the ceiling grid. By accessing the
ceiling space through an adjacent ceiling tile, plug in the snap-lock connector.
Attach the Terminal Cover using the screws provided. If using conduit, refer to
the Terminal Cover section of this manual.
7. Attach the CK10 Safety Cable, if it is being used, by screwing the eyebolt into the
safety tether point in the rear of the CSUB’s metal enclosure (see Product
Diagrams). This may be a local code requirement. It is certainly a very good
safety measure, particularly in suspended ceiling installations. For more infor-
mation see the instruction sheet included with the CK10.
Mounting clamps extend
to, but do not overhang,
edge of ceiling tile.
