This cable must be affixed to the building structure and securely clamped in such a manner to support the weight of the fan in the event the mounting hook or other parts fail. After wrapping cable around or to a structural member that will support 300 pounds, secure cable with supplied cable clamps as illustrated in Figure 8. NOTE: Leave approximately 3" but no more than 5" of slack on this safety cable to allow for possible fan movement. Do not exceed more than 5" total slack. CAUTION: It is important to note the proper installation position of the cable clamps as illustrated in Figure 8. To obtain maximum holding power, install U-bolt section of clip on dead or short end of cable and saddle on long end of cable. Improper installation reduces the efficiency of the connection by as much as 40 percent. TO FAN TO SUPPORT STRUCTURE CABLE CLAMPS 1. Attach the appropriate J-hook to the building structure member.
