Miele DA239-3 - Manual (Page 24)

The majority of the weight of the
installed Ventilation System will be
supported by the motor assembly.
Its mounting bracket must be firmly
attached to the stud framing behind
the drywall. If studs are not located
in the required locations, a plywood
backing (min.
1
/
2
" (13mm) thick)
spanning at least two studs must be
installed. Failure to adequately
support the weight as stated may
result in the Ventilation System falling
off the wall causing injury and
property damage.
(If plywood backing is not needed,
proceed to "Attaching the hood and
motor assembly to the wall.")
To install a plywood backing board
^ Determine and mark the location of
the motor assembly as outlined in
"Attaching the hood and motor
assembly to the wall."
^ Mark a horizontal line 3" (76 mm)
above and 9" (229 mm) below the
mounting screw locations.
^ Find the studs to the left and right of
the mounting location by tapping the
wall or using a stud finder.
^ Mark the center of each of the studs
with a vertical line.
Be careful not to damage any wiring
or plumbing that may be located
behind the wall. Make sure that the
power supply to the area being
worked in has been turned off at the
breaker panel before cutting into the
wall.
^ Cut out the drywall along the marked
lines and replace it with plywood of a
matching thickness (min.
1
/
2
" (13 mm)
thick). Tape the joints and refinish the
wall.
^ To complete the installation proceed
to "Attaching the hood and motor
assembly to the wall."
