3-3. Install the Rear Panel on the Wall
Be sure to confirm that the wall is strong enough to sus- pend the unit.
See either Item a) or b) below depending on the wall type.
a) If Wooden Wall
(1)Attach the rear panel to the wall with the 10 screws provided. (Fig. 11)
If you are not able to line up the holes in the rear panel with the beam locations marked on the wall, use toggle bolts to go through the holes on the panel or drill 3/16 inch dia. holes in the panel over the stud locations and then mount the rear panel.
(2)Double check with a ruler or carpenter’s level that the panel is level. This is important to install the unit properly. (Fig. 12)
(3)Make sure the panel is flush against the wall. Any space between the wall and unit will cause noise and vibration.
b) If Block, Brick, Concrete or Similar Type Wall
Make 3/16 inch dia. holes in the wall. Insert rawl plugs for appropriate mounting screws. (Fig. 13)
