Installation Steps:
1.Wood wall and ceiling installation: Drill in the 5 x 40 screws through the appropriate holes in the bracket
(figure 2-3)
2.Drywall and ceiling installation: Install the anchors and drill in the 5 x 40 screws into the appropriate
bracket holes (figure 4-5)
Take out all the parts from the package and following the accessories guideline ensure all the parts are there.
There are three different types of installation available for this product: wall mount, ceiling mount or ceiling hang.
Depending on the installation environment, the floating mounting brackets can be installed at various points for your
convenience. However, the ideal position for the mounting brackets is closer to the endcap as this will reduce
vibration and noise.
1.According to the surface of installation, choose the appropriate screws needed for mounting (regular screws for
wood surfaces, tapping screws for concrete surfaces)
2.Mount the brackets onto the surface, ensuring it is level (tip: draw a erasable level line when mounting the
brackets). See below for picture description (figure 1):
