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 PRO-
VIDE A SUFFICIENTLY SECURE SUPPORT.
