Instructions for installation of the 18” Cool-stick enclosure
ventilator

An important disclaimer

of fresh room air to flat-panel displays which have been mounted in enclosures that restrict
natural ventilation. There is a very wide range of possible installations; on-the-wall, in-the­wall, cabinet mounted, and so on. While we have made every effort to provide a reasonably
high rate of air flow at a very low noise level, the details of a given installation are beyond
our control, and there will be situations in which the Cool-stick may not be able to provide
sufficient cooling to ensure that a particular display device won’t overheat. It is the
responsibility of the installer to verify that the panel, or other equipment being cooled, is
not overheating after installation is complete.

Should the Cool-stick NOT be able to provide the required ventilation, (a test method is
suggested later), please contact Active Thermal Management as soon as possible. We will
gladly arrange for either a refund (less shipping charges) or credit towards alternate Active
Thermal Management equipment which may be more appropriate for the situation. We are
available for technical consultation at no charge week days from 8:30 to 4:30 PST at 661­294-7999.

Cool-stick installation guidelines:

To work effectively, Cool-stick must have one opening through which room air can enter
the panel’s enclosure, and another through which heated air can leave. The most
satisfactory arrangement is a slot of no less than 1” height running the entire width of the
panel just above and just below the panel.

Openings along the vertical edges of the panel are not needed, and
will upset the desired bottom-to-top airflow pattern.

It is suggested that part 1 of the test for sufficient ventilation be
performed now, before the panel is installed in its enclosure; see
below.

Using the included brackets, (note that there is a left and a right
bracket) mount the Cool-stick so that the fans’ labels are facing
upwards and the fans are either pointed straight up or are tilted toward
the panel slightly so that the air stream will hit the display’s rear panel
near the bottom, letting the air flow along the rear panel towards its top.

(See sketch above; the black rectangles are the Cool-sticks viewed on edge.)

Where possible, mounting the Cool-stick horizontal and slightly above the bottom of the
display panel is often the preferred arrangement.

One of the Cool-stick’s mounting channels slips into the round hole in each bracket, and
the other channel is placed in the slot that positions the channels at the desired angle
(protruding not more than 1/8” on the other side); see accompanying photograph. Wood
screws or other fasteners appropriate for the particular installation should be used to
fasten the brackets to the enclosure framework.

Attach the thermal probes to the part of the panel’s
structure which becomes hottest in use. (See note
below; this “hot spot” can be found during the first
part of the test when the normal operating
temperature of the display is being measured.) It is
important that the probes be in close contact with
the display; adhesive tape that isn’t affected by
moderate heat can be used to fasten the probe,
while tie-wraps and anchors can secure the probe
cable.

After installing the control unit, locating the thermal probe, and connecting the fan leads
to the control unit (connect to any FAN connector, 1 - 4), connect the power supply to the
connector (J1), and connect the thermal probe to connector THRM.

A test for sufficient ventilation –

Part 1 - Using a digital thermometer with an external probe, (readily available at

electronics suppliers), measure the temperature of the display’s back panel at the point
where the temperature is highest or the temperature of the air coming out of the exhaust
opening, if the panel has an internal fan, when the panel is operating in an open
environment. Tape or otherwise fasten the probe so that it can't move. Let the panel run
long enough to ensure that it's reached operating temperature, i.e., the thermometer
reading is steady. Note the temperature and turn the panel off.

Note: inexpensive digital thermometers may not be highly accurate, but they are
generally stable and repeatable, which is more important for this test.

Part 2 - Carefully mount the panel in the enclosure, not allowing the probe to
shift position, and apply any trim that will be used in the final installation. It should be
possible to feed the probe wire out of the enclosure so that you can measure the panel's
exhaust temperature while it's mounted in what will be its normal operating position.
Turn the panel on and allow it to heat up. The Cool-stick fans will turn on when the
temperature sensors reach about 90 degrees (F). Let the panel run until the temperature of
the exhaust stream again reaches its highest temperature.

If the exhaust temperature hasn't increased by more than a few degrees over the original
reading, the panel is being properly ventilated. It's possible that the temperature may even
decrease slightly, indicating that the extra ventilation is causing somewhat higher airflow
through the panel than normal. If the temperature is more than a few degrees higher than
the “free air” reading, check that the fans are running. If they’re not, check that the
thermal probes are in good contact with the panel.
