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-insulat-
ed, beautiful, and protective wine cellars. WhisperKOOL has put together some 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. 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 8 | 1-800-343-9463 PS 071615
Door and Door Seal
An exterior grade (1 3/4”) door must be installed as a cellar
door. It is essential 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 vapor seal to
prevent warmer moist air from leaking into 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.
Unobstructed Airow
Unobstructed airflow to and from the system is critical for the Evaporator Unit (Fan Coil Unit) and Condensing Units overall
performance and lifespan. A minimum 3 ft. clearance (5 ft. is ideal) area is crucial. The air the fans blow needs to circulate
and either dissipate or absorb heat from the space. The more air to exchange, the more efficient the system will operate.
Note: Avoid attempting to camouflage the unit. This will restrict airflow and thus the systems ability to work efficiently.
Mounting the Evaporator Unit (Fan Coil Unit)
The Evaporator Unit (Fan Coil Unit) must be mounted within 18“ of the top of the room in order to achieve sucient cooling.
As the room cools down, the warm air will rise to the ceiling. Mounting the unit high in the room will create a consistently
cool environment by capturing the warm air and replacing it with cool air. Mounting the unit low in the room will result in a
temperature variation in the room due to the unit’s inability to draw warm air from the ceiling of the cellar to the unit itself, and
cold air settling to the oor.

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. Otherwise 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 up the area
or room and adversely aect the systems 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.
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 less the electricity consumption.

If the drain line is routed through the rear
of the unit:
Insert the middle barb of the barbed tee fitting
into to the end of the drain line coming from
the evaporator. Rotate fitting so tee is in the
orientation shown in the diagram on the right.
Connect a 3” piece of 1/2” drain line to the barb

drain tubing to the bottom barb of the tee.
Route the drain line to an appropriate drain
location.
NOTE: The fitting should be placed vertically
with the 3” piece facing up.
If the drain line is routed through the
bottom of the unit:
Connect the drain line directly to the second
barbed 90° installed in step 15 of the
installation instructions. Route the drain line to
an appropriate drain location. No tee is
required if draining through the bottom of the
unit.
NOTE: The fitting should be placed
vertical with the three inch cut out
facing up.
Failure to install the drain line
voids the warranty.
To prevent mold from growing,
allow the drain line to hang
above the water line.
WRONG: Drain line is under water.
DRAIN LINE
Drain Line
All systems come with a drain line for additional removal of excessive condensate. It is mandatory to install the drain line,
whether it leads through the wall and out of the cellar or remains inside the cellar. During operation, the cooling system will
strip excess water from the air in order to maintain the proper level of humidity within the cellar. However, in extreme humidity,
additional condensate will be removed, thus the drain line will prevent overflow and leaking by allowing for discharge of the
additional condensate.
Condensation Drain Line
The condensation drain line tube is used to remove excess condensation from the Evaporator Unit ( Fan Coil Unit) to a proper
discharge location. It is important that the drain line tube is properly connected and used to prevent leakage and other problems
associated with excess condensation.
Failure to use the condensation drain line tube will void the warranty on the unit.

Page 14 | 1-800-343-9463 PS 071615
LIQUID MEASURING THERMOSTAT
The WhisperKOOL Series cooling units come equipped with a liquid temperature measuring thermostat. This incorporates the
following advantages:
Liquid Measuring Thermostat
To assure a consistent temperature, place bottle probe at least 3 ft. away from the air output and not in the flow of the air.
To Use the thermostat:
1. Locate an empty wine bottle.
2. Fill 3/4 full with room temperature tap water.
3. Place bottle probe securely into bottle.
4. Place bottle with probe level and to the side of the unit in your wine
cellar. It is recommended that it is placed in a central location of your
wine cellar. Avoid pulling too much on the probe cord. It may become
disconnected, resulting in non-operation of the unit.
Note: The thermostat can be set between 50°F
and 67°F.
Remember: The WhisperKOOL unit operates based on the temperature
of the water. Do not be misled by thermostats reading air temperature.
The air temperature in the cellar will be cooler than the liquid
temperature of the wine while it is coming to optimum balanced
temperature.
