Installation
The MI347 may be placed upright on its four feet
or custom installed with the four feet removed. If
removed, retain the four feet and fastening screws for
any future re-installation. The panel cutout, ventilation
cutout and unit dimensions are shown in the drawing
on the right side of this page.
It is necessary to provide adequate ventilation for
cool operation, ensuring long life for the MI347. Do
not install the MI347 above heat generating compo-
nents. When the MI347 is installed in a cabinet with
other components, a ventilation fan may be added to
provide cool operating temperature.
A custom cabinet installation needs to provide the
following minimum spacing for cool operation:
Allow at least 3 inches (7.6cm) above the top,
2 inches (5.08cm) below the bottom, 3 inches
(7.62cm) behind the rear panel and 2 inches
(5.08cm) on each side of the MI347, providing
airflow. Allow 2-1/2 inches (6.4cm) in front of the
mounting
1
panel for clearance. Be sure to cut out a
ventilation hole in the mounting shelf according to
the dimensions in the drawing.

When the MI347 is installed together with other
McIntosh Components, check clearances on all
components before proceeding.
