Unit Mounting
Mounting the unit in the cellar has a significant impact on the unit’s ability to cool the air in the room. A law of nature states that warm air rises while cool air falls. The unit must be mounted high in the room in order to capture the warm air and replace with cool air. If the unit is mounted low in the cellar, it has a tendency to circulate the cool air at the

bottom of the cellar but has no ability to draw the warm air from the higher space in the cellar. This will result in an inconsistent temperature range.
Thermostat
If the WhisperKOOL unit is not cooling the room, it might be due to a faulty thermostat. Use the following procedure to test the thermostat (see pg. 25).
1.) Unplug the WhisperKOOL unit.
2.) The PDT thermostat is attached to the front of the WhisperKOOL unit with two screws, one at each end of the thermostat. Remove the screws and detach the PDT.
3.) Unplug the PDT from the main unit, and plug in the
thermostat installed.
4.) Plug the WhisperKOOL unit back in. The unit will begin running and cooling immediately. Let the unit run for 24 hours.
5.) After 24 hours, use an accurate thermometer (preferably a high- quality digital thermometer) to measure the temperature of air coming out of the WhisperKOOL unit’s front fans. If it is cooling the room, then the problem may lie with the thermostat.
If the WhisperKOOL unit cools the room without the PDT installed, then the thermostat should be replaced. The by- pass plug will allow the WhisperKOOL unit to continue to function, but it will not be able to monitor or maintain the correct temperature automatically without the thermostat.
If you continue to run the WhisperKOOL on the
