1. Separate the fan and grille sections.
2. Finish the grille as required.
3. Reassemble in intake or exhaust mode.
4. Install in opening.
5. Install thermal switch and connect to power source.
To install Cool-vent:
1. Separate the fan and grille sections by removing the nuts on the threaded studs. Use a
5/16" open-end wrench.
2. Finish the wooden grille section as desired. Allow to dry completely before reassembling
to the fan section. (Read the following cautionary note.)
**IMPORTANT**
In order to protect the grille and prevent warping or cracking, you must
seal the grille on EACH side and in between all slots prior to installation.
Whether you are painting, staining, or sealing the grille with urethane, they must
have the appropriate finish applied BEFORE they are installed. If the grille is
not protected in this way, Active Thermal Management will not be responsible
for any warping or cracking that might occur.
3. Reassemble the two sections in desired operating mode. Do NOT use excessive force
when tightening the nuts holding the fans.
a. For "intake" mode, reassemble as they were shipped, with the fans' labels facing
away from the grille section.
b. For "exhaust" mode, the fans' labels should face the grille section.
4. Cut an opening of appropriate size (see chart above) at the desired location. Pass the
thermal switch and power supply through the opening from the outside and screw or bolt
the grille to the mounting surface either from the outside or inside as appropriate.
5. Attach the thermal probe to the equipment to be monitored, or mount the probe so that it
can sense the temperature of the hottest air in the enclosure. (This might be at the highest
point in the cabinet or just above the hottest component.)
