What Is the WhisperKOOL Slimline Cooling System?
The WhisperKOOL Slimline system 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 Slimline Work?
The WhisperKOOL Slimline cooling system is especially designed for the use and application to maintain optimal conditions for wine storage and aging. The system is fully self-contained and can be installed as a “Thru-
The-Wall’ application. The standard “Through-the-Wall” units are temperature controlled via a bottle probe.
Temperature Setting
The WhisperKOOL unit can be set at any temperature within the acceptable wine-aging range of 50°F to 67°F. It
is designed to cool 30°F cooler than the ambient temperature of the space to which it is exhausting.

PREPARING THE WINE CELLAR
The performance and life of your WhisperKOOL unit are contingent upon the steps you take in preparing the
wine cellar.
Note: Improperly preparing your enclosure or incorrectly installing your WhisperKOOL unit may cause unit
failure, leaking of condensation, and other negative side eects.
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 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 specic 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 factor 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-factor, or quality of insulation, is determined by the rate at which heat
passes through the insulation. The higher the R-factor, 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, R19
recommended, R30 for ceiling and exterior walls)
Vapor Barrier
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 inltration 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.
Page 7
Page 8
Mounting the Unit
The unit should be mounted within 18“ of the top of the room in order to achieve sucient cooling. As the
room cools down, the warm air will rise to the ceiling. Mounting the WhisperKOOL 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.
Ventilation
The necessity of dissipating heat away from the unit is critical to the unit’s performance and cannot be overstated. As the unit operates and cools, a greater amount of heat is generated on the exhaust side of the unit.
Adequate ventilation is required in order to dissipate heat away from the unit. If ventilation is inadequate, the
exhaust will heat up and adversely aect the unit’s ability to cool.
Unobstructed Airow
Unobstructed airow to and from the unit is a critical factor in the unit’s overall performance. Make sure there
is a minimum 3 ft. horizontal clearance from the rear of the unit as well as a minimum 3 ft. clearance in front of
the evaporator fans. This will assure that the unit can move the air around in an ecient manner. Avoid any
attempt to camouage the unit by installing racking in front of the unit. This will restrict the airow and lower
the performance of the unit.
Ambient Temperature Factor
The cooling system has the ability to cool a maximum of 30°F below the ambient temperature of the room it is
exhausting to. Therefore, you want to exhaust the unit in a room which will not exceed 85°F and preferably a
consistent 75°F. Otherwise the unit will not have the capacity to keep the wine at a desirable 55°F.
Page 8 SL 072710
Page 9
Door and Door Seal
At minimum 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 in and the warm air
out. One of the most common problems with cooling units
running continually is the door not sealing properly.

Electrical Needs
The WhisperKOOL System requires a dedicated 115-volt 15-amp circuit. The unit draws a large amount of amps
at initial start up. By designating a dedicated circuit breaker, you will guarantee the unit has enough power to
run eectively. Contact an electrician for assistance with the installation of this dedicated electrical circuit:
1. Match the electrical outlet to the plug provided on the WhisperKOOL unit.
2. Provide a dedicated circuit and wiring for the unit.
Electrical Outlet
The unit is equipped with a twelve foot power cord located on the evaporator side of the unit. Plug your
WhisperKOOL unit into a surge protector or power conditioner. As with any sensitive electrical equipment, the
WhisperKOOL electrical equipment may be damaged by power surges and spikes. Power surges and spikes are
not covered in the WhisperKOOL warranty.
WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.
TEST THE UNIT PRIOR TO INSTALLATION
To prepare it for testing before installation in wall:
• Remove unit from box
• Place unit on tabletop
• Plug in unit to electrical outlet
• Plug in bottle sensor
• Turn on to test (Temperature dierential should be 10°F across coils)
• Turn o after test
• Remove bottle sensor
Testing Unit - Place the WhisperKOOL system on a tabletop to prepare it for installation and testing. Plug sys-
tem into a live electrical outlet and turn unit on. The system may take up to 10 to 15 minutes before running
cool. Once the operation has been tested, turn the unit o, and unplug the unit from the electrical outlet.*
Units weigh 50-70 pounds and are cumbersome for one person to carry. We recommend that you get someone else to help you during the installation process. NEVER LAY UNIT ON ITS SIDE.
* Note: If the system does not seem to be running cool after 15 minutes, please refer to the Troubleshooting
Guide on Page 19.

INSTALLATION cont.
CELLAR SIDE
STEP 4:
Slide the cooling unit in from the cellar side with the thermostat facing the outside of cellar. The outer ange should be
ush to the wall. Secure the ange to the wall through the
pre drilled holes. The screws should penetrate the studs and/
or frame as well as the upper and lower supports to provide
adequate support for the WhisperKOOL system. Seal all cracks
and gaps around the WhisperKool Slimline unit with an airtight sealant or caulking to prevent air leakage.
Note: If you use decorative molding, it should be attached to the walls
and never to the cooling unit.
STEP 5
Attach the condensate drain line
The condensation drain line tube is used to remove excess condensation from the 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.
STEP 6
If removed, install the grille’s on both sides of the unit and plug in the power cord. The use of an extension
cord is not recommended.

LIQUID MEASURING THERMOSTAT SYSTEM
The WhisperKOOL Slimline cooling unit comes equipped with a liquid temperature measuring thermostat
system. This system incorporates the following advantages:
1. Self-Calibrating Probe: The probe contains a sensor chip, which actually communicates back and
forth to the thermostat. This results in a consistent temperature setting and accuracy. Do not remove
the tip from the probe!
2. Heavy-duty Circuitry: The circuitry within this new unit has been upgraded to resist power surges,
which play havoc on electrical components. This improvement will ensure years of trouble-free use.
However, for the highest reliability, we recommend that the customer install a surge protector for the
unit itself.
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. 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 System is based on the temperature of
the water. By measuring the liquid temperature rather than air, the unit
will operate 75- 80% of the time.

SYSTEM OPERATION: STANDARD & REMOTE
Initial Start-Up
When power is applied to the unit, the control will
briey display all symbols, and the Compressor
symbol will be displayed (if unit is calling for cooling).
There may be a brief delay prior to the evaporator
and condenser fans turning on.
Normal System Cycle
After the bottle probe has reached the set point (all
units are shipped with the set point of 55°F and a
dierential of 1°F). The WHM is an adjustable feature which allows the customer the convenience of
managing the humidity enhancement of their wine
cellar. The WHM is one of the many Customer Preference Selection features which allow the customer the
ability to ne tune the controls. This feature is set to 0
when shipped but if needed can be adjusted.
Anti Short Cycle
The Anti Short Cycle ensures that the unit will remain
o for a period of 5 minutes after the unit has reached
the set point to allow the pressure in the refrigeration
system to equalize prior to starting the compressor.
Defrost Cycle
The Defrost Cycle is a precautionary measure, as icing
or frosting of the coil does not occur during normal
operation. The system will go through a defrost cycle
every 4 hours. During the defrost cycle, the in-cellar
fan will provide air ow across the in-cellar coil, which
will evaporate any frost accumulation.
Bottle Probe Failure Protection
In the event that a bottle probe should fail, the APST
(Advance Product Safety Technology) will automatically transition the Refrigeration Compressor cycles
to a pre-determined time series (based on detailed
laboratory testing), which will ensure that the product is kept within the safe range.
