edge to the outside edge and cut PVC pipe at a
slight angle 1/4" (6 mm) shorter than the thickness of
the wall. (Fig. 11)

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 8 screws
provided. (Fig. 13)
If you are not able to line up the holes in the rear
panel with the beam locations marked on the wall,
use rawl plugs or toggle bolts to go through the
holes on the panel or drill 3/16" (5 mm) dia. holes in
the panel over the stud locations and then mount the
rear panel.
(2) Double check with a carpenter’s level or tape mea-
sure that the panel is level. This is important to
install the unit properly. (Fig. 14)
(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" (4.8 mm) dia. holes in the wall. Insert rawl
plugs for appropriate mounting screws. (Fig. 15)
