INTRODUCTION
Customer Service
Thank you for purchasing a WhisperKOOL Extreme Series cooling unit. We strive to provide the highest-quality products and the
best possible customer service. If you have any questions about your WhisperKOOL unit, please call us at 1-800-343-9463 or visit
www.whisperkool.com.
Using the Manual
This manual is intended to assist in the proper installation and maintenance of the WhisperKOOL cooling unit. In order to
ensure the longevity of your cooling unit, the equipment should be installed correctly and have a proper care and maintenance
schedule. Please read and review this manual carefully and keep it for future reference.
What is the WhisperKOOL Cooling Unit?
The WhisperKOOL cooling unit is a specialized refrigeration unit designed for one purpose only: to maintain the optimal
temperature and humidity levels conducive to the proper storage and aging of ne wines. It is a self-contained cooling unit
designed to be used as a forced-air, through-the-wall unit.
How Does the WhisperKOOL Extreme Series Work?
The WhisperKOOL unit is especially designed to maintain optimal conditions for wine storage and aging. The unit is fully self-
contained and can be installed through most walls. The unit is also capable of a more exible ducted application, which allows
the unit to be placed in an indoor remote site, resulting in a quiet airow. The standard through-the-wall and ducted units are
temperature-controlled via a bottle probe.
NOTE: The remote unit comes standard with a 50-foot bottle probe. Additional lengths are available from WhisperKOOL.
Temperature Setting
The WhisperKOOL cooling unit can be set at any temperature within the acceptable wine-aging range of 50–67°F. It is designed
to create a dierential of up to 55°F between the cellar and the ambient temperature (as long as the space to which the unit is
exhausting does not exceed 110˚F).

BEFORE YOU START
1. Inspect the unit before installation. If damage is found, please contact your distributor or WhisperKOOL Customer Service
at [email protected].
2. The unit should remain in an upright position for 24 hours prior to operation.
3. The WhisperKOOL unit requires a dedicated 115V, 20-amp circuit. Use a surge protector with the WhisperKOOL unit. Do not
use a GFI (ground fault interrupter) line.
4. The unit is designed to gently cool down the temperature of the cellar over time by cycling cooler and cooler air throughout.
Test the unit prior to installation.
5. You are REQUIRED to install a drain line to remove condensation from the unit.
6. The WhisperKOOL unit is intended for use in properly designed and constructed wine cellars. Hire a professional wine
storage consultant with a valid contractor’s license to build your wine cellar.
Never try to open the WhisperKOOL unit, repair it yourself, or use a service company
without WhisperKOOL’s authorization. This will void your warranty.
If you encounter a problem with your WhisperKOOL unit, please refer to the Troubleshooting Guide. If you have any further
questions, concerns, or need assistance, please contact WhisperKOOL Customer Service at 1-800-343-9463. Please be sure all
testing has been completed prior to contacting Customer Service. Please have your results ready for your representative.

UNIT SPECIFICATIONS
FAN SPEED
Fan speed selection is determined by the amount of heat that needs to be removed from the cellar and the type of installation
(through-the-wall or fully ducted). Fan speed selection is based on the cellar size, insulation factor, door seal, and desired wine
temperature. When initially installing the unit, set the fan speed to the High setting to quickly chill the wine cellar. Once the
wine cellar reaches the desired temperature, a lower fan speed may be selected. In the event that the outdoor temperature rises
above 90°F, (when exhausting to the outdoors) a higher fan speed may be required.

Warranty Two-year limited warranty (parts and labor)
* Sizing the Unit to the Room
The specication chart will provide information on the unit's cooling capacity. There are circumstances in which a cellar design may
require a larger unit due to preexisting design restrictions. Certain building materials such as glass, stone, or concrete may seem
adequate but do not oer the insulation capacity required to maintain the optimum temperature for storing wine. We recommend
purchasing a unit with a larger capacity to compensate for these design limitations. Undersized cooling units can lead to premature
failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.
