3-20. Installing the Rear Panel onto the Wall
Confirm that the wall is strong enough to support the unit.
See either Item a) or b) below depending on the wall
type.
a) If the Wall is Wooden
(1) Attach the rear panel to the wall with the 10 screws
provided. (Fig. 3-66)
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 5 mm dia. holes in the panel over the
stud locations and then mount the rear panel.
(2) Check with a tape measure or carpenter’s level.
This is important so that the unit is correctly
installed. (Fig. 3-67)
(3) Make sure the panel is flush against the wall. Any
space between the wall and unit will cause noise
and vibration.
b) If the Wall is Brick, Concrete or Similar
Drill 4.8 mm dia. holes in the wall. Insert Rawl plugs for
appropriate mounting screws. (Fig. 3-68)
