INSTALLATION FUNDAMENTALS

RUNNING THE SPEAKER WIRE IN NEW CONSTRUCTION

IMPORTANT: IF YOU HAVE DOUBTS ABOUT WHETHER YOU ARE CAPABLE OF INSTALLING A NILES CEILING MOUNT LOUDSPEAKER, PLEASE CONSULT A NILES DEALER OR PROFESSIONAL INSTALLER. THEY HAVE SPECIAL TOOLS, TECHNIQUES, AND EXPERIENCE TO MAKE THE IMPOSSIBLE JOB POSSIBLE. THE INSTALLER CAN PROVIDE YOU WITH AN ESTIMATE BEFORE ANY WORK IS DONE.

OBSERVE SAFETY FIRST!

•Always wear gloves, safety goggles, and head protection gear when drilling or cutting holes.

•Avoid drilling near nails – they ruin bits and can cause injury.

•Be careful using “hole-hogs” and other powerful electric drills. The torque of this drill when suddenly stopped by a nail can break the wrist of a strong man.
