DUCTING
A WhisperKOOL XLT ducting kit is available for purchase. The kit allows the warm air to exhaust to several places such
as an attic, an adjacent room, or outside. The goal is to get the warm exhaust air away from the rear intake of the unit.
The customer will need to purchase 8” ex ducting, along with any hangers needed to run the ducting outside.
See page 29 for more information on purchasing a XLT ducting kit.
Using the Thermostat Controller
The in-line fan will turn on and push warm exhaust air away from the WhisperKOOL® unit, preventing
the unit from overheating. The in-line fan is capable of moving warm air through 25 feet of 8” ex
ducting (not included). The in-line fan can be set to automatically turn on at varying temperatures in
order to conserve the most electricity.
Setting the Thermostat Controller to its lowest setting will turn the fan on at lower temperatures
(Around 70° F). Setting the Thermostat Controller to its highest setting will turn the fan on at higher
temperatures (Around 100° F). If the unit isn’t cooling properly, setting the thermostat controller to a
lower setting may x the problem.
