If Wooden Wall

Fig. 3-38
  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)  Double check with a carpenter’s level or tape measure 
that the panel is level. This is important to install the unit 
properly. (Fig. 3-39)

(3)  Make sure the panel is flush against the wall. Any space 
between the wall and unit will cause noise and vibration.
