INTRODUCTION
Customer Service
Thank you for purchasing a WhisperKOOL cooling system. We strive to provide the highest quality products and the
best possible customer service. If you have any questions about your system, please call us at 1-800-343-9463 or visit
WhisperKOOL.com.
Using the Manual
This Owner’s Manual is intended to assist in the proper maintenance of the cooling system. In order to ensure the
longevity of your cooling unit, the equipment should be installed as outlined in the this Owner’s Manual. It is also vital
to establish a proper care and maintenance schedule. Please read and review this Owner’s Manual carefully and keep it
for future reference.
What is the WhisperKOOL Cooling System?
The WhisperKOOL cooling system is a specialized refrigeration system designed for one purpose only: to maintain
the optimal temperature and humidity levels conducive to the proper storage and aging of ne wines. This system
produces minimal in-cellar noise and has the most lenient exhaust requirements. An exterior housing is required for
outdoor condensing unit installations.
How Does the Cooling System Work?
Similar to the air conditioning systems used for homes, the evaporator and condensing units are installed in separate
locations and are connected by a refrigerant line set. The evaporator portion is commonly installed in the wine cellar,
with the condensing unit located either outside or in a remote indoor location that is ventilated. An exterior housing is
required for outdoor condensing unit installations.
Temperature Setting
The WhisperKOOL system can be set at any temperature within the acceptable wine-aging range of 50°F to 70°F. It
is designed to cool up to 55°F cooler than the ambient temperature of the space to which the condensing unit is
installed.

BEFORE YOU START
1. Inspect the system before installation. If damage is found, please contact your distributor or WhisperKOOL
Customer Service at 1-800-343-9463.
2. The condensing unit requires a dedicated 115 volt 20 amp circuit. Use a surge protector with the unit. Do not use
a GFI (Ground Fault Interrupter) line.
3. It is REQUIRED to install a drain line to remove condensation from the evaporator unit.
4. The system 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.
5. WhisperKOOL requires that all Split Systems be installed by a certified HVAC-R technician only.
6. Warranty is not active until a Warranty Checklist has been received, reviewed, and approved.
If you encounter a problem with your WhisperKOOL system, please refer to the Troubleshooting Guide on page 48.
If you have any further questions, concerns, or need assistance, please contact WhisperKOOL’s 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.

The performance and life of your system is contingent upon the
steps you take in preparing the wine cellar.
Note: Improperly preparing your enclosure or incorrectly installing your
unit may cause unit failure, leaking of condensation, and other negative side eects.
IT IS HIGHLY RECOMMENDED THAT YOU OBTAIN THE ASSISTANCE
OF A WINE STORAGE PROFESSIONAL.
Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build
well insulated, beautiful, and protective wine cellars. WhisperKOOL has provided useful tips to assist in the installation
process. Our recommendations are meant to act as a guide in the process of building a proper enclosure. Your
intended location may have specic needs that we do not address.
Wall & Ceiling Framing
Build wine cellar walls using standard 2x4 or 2x6 construction methods and ceiling joists following the guidelines of
local and state codes in your area. As a general rule, the thicker the walls and the higher the insulation value in your
cellar, the better it will be at maintaining a consistent temperature.
Insulation
Insulation is REQUIRED with the use of the WhisperKOOL product. Standard berglass or rigid foam insulation is
normally used in cellar construction or, in some cases,“blown-in” insulation is used. It is very important that all walls
and ceilings are insulated to keep the cellar temperature as consistent as possible during the summer and winter
months. The R-value, or quality of insulation, is determined by the rate at which heat passes through the insulation.
The higher the R-value, the more resistant the insulation is to conducting heat. Using higher R-values in insulation will
lower your operating costs and unit run time. (R-13 minimum, R-19 recommended, R-30 for ceiling and exterior walls.)
Vapor Barrier
Water vapor creates its own pressure (separate from the air pressure) and will intrude into colder/drier areas. A vapor
barrier is REQUIRED to prevent the intrusion of water vapor so that the cellar can be kept at the correct temperature
and humidity. 6 mm plastic sheeting (recommended) should be applied to the warm side of the cellar walls. The
vapor barrier must also be applied to the outside walls and ceiling. If it is impossible to reach the outside, then the
plastic must be applied from within the cellar. The most common method is to wrap the entire interior, leaving the
plastic loose in the stud cavity so the insulation can be placed between each stud. All of the walls and ceiling must be
wrapped in plastic for a complete vapor barrier.
In areas of high humidity, such as Southern and Gulf States, the vapor barrier will prevent inltration of warm, moist
air. The moist air can cause mold to form, and standing water in drain pans promote microbial and fungal growth that
cause unpleasant odors and indoor air quality problems. If mold is found, remove it immediately and sanitize that
portion of the unit.
Note: High humidity signicantly increases the heat load on the cooling system.
Any break in the vapor barriers (cut, nail hole, over-lapping, etc.) will allow a moisture leak and must be sealed. The
electric conduit is a “duct” for vapor to travel in. The conduit should be caulked and sealed on the warm air end.
PREPARING THE WINE CELLAR

Page 10 | 1-800-343-9463 WCM 033114
Unobstructed Airow
Unobstructed airflow to and from the system is critical for the system’s overall performance and life span. A
minimum three-foot clearance (five-foot is ideal) area is crucial. The air blown by the fans needs to circulate and either
dissipate or absorb heat from the space. The system will operate more efficiently with a greater amount of air to
exchange.
Door and Door Seal
An exterior grade (1 3/4”) door must be installed as a cellar door. It is very important that weather stripping is attached
to all 4 sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have a very good seal
to keep the cool cellar air from escaping out of the cellar. One of the most common problems with cooling systems
running continually is due to the door not sealing properly. In cases where glass doors are used and the room size
is close to the recommended system size, the next larger size WhisperKOOL system should be used. This will
compensate for the insulation loss due to the lower insulating rating of glass.
Note: Avoid attempting to camouflage the unit. This will restrict
airflow, and thus the system’s ability to work efficiently.

www.whisperkool.com | Page 11
Ambient Temperature Factor
The cooling system has the ability to cool a wine cellar eciently to 55°F as long as the ambient temperature of the
area that it is exhausting to does not exceed 110°F. Therefore, you want to exhaust the condensing unit in a space which
will not exceed 110°F and will allow for proper dissipation of the heat exhausted by the condensing unit. Without proper
heat dissipation the system will not have the capacity to keep the wine at a desirable 55°F.
Ventilation
The necessity of dissipating heat away from the condensing unit is critical to the performance and cannot be
overstated. As the system operates and cools, a greater amount of heat is generated on the condensing side of the
system. Adequate ventilation is required in order to dissipate heat away from the condensing unit. If ventilation is
inadequate, the exhaust will heat the area or room and adversely aect the system’s ability to cool. In some cases, it
may be advisable to install a vent fan to dissipate heat within the exhaust area on the condensing side of the system.
However, you must have a fresh air inlet as well.
Note: If you are unsure about having adequate ventilation in your install location, please
contact us to assess your specic installation at [email protected] or 1-800-343-9463.
WARNING! allowing your system to operate in high ambient temperatures for
extended periods of time will greatly decrease the life of your system and void
your warranty. The cooler the temperature of the air entering the condenser coil,
the more cooling capacity the system has. The less heat gain through the common
wall, the lower the consumption of electricity.
