Instructions for installing and using the Cool-it
II
NOTE: The Cool-ii
II
was
designed
io
cool
componenis
in an open,
or
panialiy
open
environment,
such
as
on a
shelf,
in
a
bookcase,
or
in
a cabinet
with
no
doors
and/or
an
open
back.
It
cannot
cool
components
in
sealed
enclosures;
it
would
just
circulate
the
same
hot
air
within
the
enclosure,
providing
little
cooling.
Active
Thermal Management
offers
a
complete
line
of
cooling
equipment
designed
to
cool
entire
enclosures,
from
the
smallest
to
the
largest,

The Cool-it I
ITM
is designed to be
placed over the hottest part
of
an
amplifier
or
receiver.
If
there is any
doubt about where that is, run the
amplifier
or
receiver for an hour or
more, and feel the cover; center the
Cool-it
II
on the hottest area.
Depending on the model
of
receiver
or
amplifier, the Cool-it
II
may want to run
from front to back
or
side to side along the top cover.
Next, select the location for the thermal probe, the small silver-
colored cylinder attached to the control board located between
the fans. Position the probe where it can sense the heat from
the amplifier, probably under the Cool-it II. Plug the power
supply into an
AC
outlet that is always live, and plug the power
supply's output lead into the connector attached to the control
unit. Note that the small temperature display on the control
board reads in degrees Celsius, not Fahrenheit.
When the temperature
at
the thermistor reaches 32C degrees,
(about 90F - see below) the fans will begin to tum.
The
fans will
stop when the temperature falls below 29C (about 85F). A hair
dryer can be used to check for proper operation.
The fans may run continuously. Cable boxes, satellite receivers, some whole-
house amplifiers and digital recorders run continuously and their heat may be
