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:
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
by-pass plug. The by-pass plug allows you run the
WhisperKOOL without having 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.
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.
Mount WhisperKOOL high in the room.
