Niles Audio CM750DS, CM760DS warranty NEW Construction Installation, Insulating the Wall Cavity

3.Cut a foot-long piece of coat hanger. Bend the wire (creating a right angle) leaving 5-1/2” at one end (this allows for the extra width of the mounting dogs). Poke the “L-shaped” wire into the pilot hole and turn it in a complete circle and move it into the ceiling cavity to make sure you have approximately 4-3/8” of depth. If the wire’s movement is obstructed by anything, fi ll the hole(s) with spackle and try another location.

4.If the coat hanger moves freely in a complete circle and you have suffi cient depth, hold the template up to the ceiling surface. The cardboard square with the circular hole is the template. The inner perforated circle within the larger circle that was removed in step 1 earlier is the paint mask. Keep it for painting the loudspeaker later. Outline the circular cutout on the ceiling surface lightly with a pencil. Drill the starting point of your cut with a 1/4” bit.

5.If you are cutting drywall use a sheetrock or keyhole saw, cut the hole with the saw at a 45° angle. That way the drywall section can be replaced cleanly if there is an unseen obstruction behind the wall.

IMPORTANT: BE VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE.

IF YOU FEEL EXTRA RESISTANCE AS YOU ARE CUTTING, STOP.

NEW CONSTRUCTION INSTALLATION

INSULATING THE WALL CAVITY

If feasible, fi ll the wall cavity with insulation at this point.

MOUNTING THE NEW CONSTRUCTION BRACKET

The optional CM700DS BKT can be used with the CM730DS, CM750DS or CM760DS loudspeakers. The hole saving bracket enables a faster and cleaner fi nal installation of the loudspeaker. It forces the drywall installer to cut out the loudspeaker hole for you and provides wire ties for the loudspeaker wire, reducing the risks of accidental loss or movement of the wire. In addition, it enables you to align your loudspeakers with other ceiling fi xtures with great accuracy since you can really see exactly where the loudspeaker will be. To install the bracket, fi rst pivot the long wing out until it stops, which will be in straight line with the short wing. The wings and brackets have centering lines to simplify placement of the loudspeakers. Screw one side of the assembled bracket with wings to the joist using one of the supplied screws. Level the bracket. Screw the other side of the bracket/wing assembly to the joist. Two screws on each side make for a very secure installation. Secure the wire to the bracket using bracket’s wire tie tab. The drywall installers will cut the drywall to the exact size of the bracket. (See Figure 2)

CONCEALING LOUDSPEAKER WIRE FOR A FUTURE INSTALLATION

Attach the loudspeaker wire in a loop between the ceiling joists and carefully mark the exact location of the wire on a set of plans. Ask the general contractor to inform the drywall installers that the loudspeaker wire loops are concealed for future installations.

UNPACKING AND FINAL INSTALLATION

1.Remove the top piece of styrofoam from the box. You will fi nd two loudspeakers bagged in a lower portion of packing. Remove the loudspeaker from the bag. The metal grille is installed on the loudspeaker and will need to be removed. This is easily done by pulling on the small black fabric strap.

2.Remove the loudspeaker module from the frame by turning the loudspeaker assembly counter-clockwise using the two tabs provided. Place the loudspeaker assembly to the side when removed for installation after the frame has been mounted. Take care to place it so that the woofer, tweeter or crossover on the rear are not damaged. (See Figure 3)

3.Insert the frame into the hole by carefully holding it with both hands and angling it slowly into the hole until the frame is fl ush with the ceiling. Holding it in place carefully with one hand, use a cordless drill to begin mounting the frame.

4.Tighten the four ‘dog’ screws using a #2 Phillips bit. Use low torque and low speed or you may damage the frame. This should pull the frame and mounting dog together (sandwiching the drywall) so that the frame is absolutely fl ush with the wall surface. There should be no gaps between the wall and the frame.

IMPORTANT: DO NOT OVER TIGHTEN THE SCREWS! OVER TIGHTENING THEM MAY MAKE THE GRILLE DIFFICULT TO INSTALL

5.At each loudspeaker location, route the wire through the installed frame, then separate the loudspeaker wire so that at least 2 inches of each conductor are free. Strip away 1/4 inch of insulation from each individual loudspeaker wire.

6.Retrieve the loudspeaker module removed from the frame in step 2.

7.Press down each spring-loaded connector one at a time, insert the appropriate conductor and then release the connector. Check to be sure that the connector is making contact with stripped wire and not the wire jacket. Gently tug on the loudspeaker wire to make sure it is held in place. If not, repeat this procedure until it is.
