Installation
Installation
The MI254 needs to be placed upright on its four feet.
It also can be custom installed. Remove the four feet
when it is custom installed and retain them with the
fastening screws for possible future use. The required
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 MI254. Do
not install the MI254 above heat generating compo-
nents. When the MI254 is installed in a cabinet with
other components, use a ventilation fan 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 MI254, providing
airflow. Allow 2-1/2 inches (6.35 cm) in front of the
mounting

panel for clearance. Be sure to cut out a
ventilation hole in the mounting shelf according to
the dimensions in the drawing.

When the MI254 is installed together with other
McIntosh Components, check clearances on all
components before proceeding.
