INSTALLATION INSTRUCTIONS CEILING BRACKET AN-PHCM20 1.1 a. Select straddle beam or single beam installation. b. Use the ceiling bracket as a template to mark the location where the pilot holes should be drilled. c. Drill the pilot holes for the support screws using a 1/8" drill bit into the center of the beam. (See Figs. 2 and 3). 1.2 Screw the ceiling plate to the beams. Use at least 6 screws and metal washers supplied with the unit. These screws should be tightened firmly to insure a vibration-free support. (See Figs. 2 and 3). Two sizes of hex head lag bolts are provided. Use shorter screws for sheet rock surfaces and use the longer screws if the ceiling surface is constructed of a wood lath and plaster. CAUTION: THE BRACKET MOUNTING SCREWS MUST GO DIRECTLY INTO THE BEAMS. SHEETROCK OR LATH AND PLASTER WILL NOT PROVIDE A SUFFICIENTLY SECURE SUPPORT. FIGURE 2.
