Installation - McIntosh MC252 Owner's Manual

Installation

Caution: The MC252 Amplifier weight is 94.5 pounds
(42.87 kilograms). It requires two or more persons
to safely handle when moving the amplifier.
The MC252 can be placed upright on a table or shelf,
standing on its four feet. The
four feet may be removed
from the bottom of the
MC252 when it is custom
installed as outlined below.
The four feet together with
the mounting screws should
be retained for possible fu-
ture use if the MC252 is re-
moved from the custom in-
stallation and used free
standing. It also can be cus-
tom installed in a piece of
furniture or cabinet of your
choice. The required panel
cutout, ventilation cutout
and unit dimensions are
shown.
Always provide adequate
ventilation for your MC252.
Cool operation ensures the
longest possible operating
life for any electronic instru-
ment. Do not install the
MC252 directly above a heat
generating component such
as a high powered amplifier.
If all the components are in-
stalled in a single cabinet, a
quiet running ventilation fan
can be a definite asset in
maintaining all the system
components at the coolest
possible operating tempera-
ture.
A custom cabinet instal-
lation should provide the fol-
lowing minimum spacing
dimensions for cool opera-
tion. Allow at least 6 inches
(15.24 cm) above the top, 2
inches (3.81cm) below the
bottom and 1 inch (2.54 cm)
on each side of the amplifier,
so that airflow is not ob-
structed. Allow 16 inches
