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. Each unit has a bypass plug included with the instruction guide. The bypass plug is used to help troubleshoot the cabinet when it is not cooling correctly. It allows you to determine whether the problem lies within the thermostat or the cooling unit itself. The process of using this plug is as follows:
Mount WhisperKOOL high in the room.
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

If the WhisperKOOL unit cools the room without the PDT installed, then the thermostat should be replaced. The
The unit should be ran for 24hr. If you continue to run the WhisperKOOL you will need to turn off the WhisperKOOL unit periodically to keep it from icing up. We recommend cycling the unit on and off every eight hours if possible or as needed. It is recommended to run during the day and turn off at night.
For replacement of the PDT, please contact Customer Service. See Warranty Service on page 30.
