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 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 technician’s manual. It is also vital to establish a proper care
and maintenance schedule. Please read and review this 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 unit (fan coil unit) 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 is 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 system is designed to maintain a cellar temperature of 55°F as long as the ambient temperature does not exceed 110°F.
WARRANTY REGISTRATION
In order to activate the warranty of your system, the verication and operational
documentation must be completed by the certied refrigeration technician
installing your system and submitted via mail, fax, or e-mail.

BEFORE YOU START
1-800-343-9463
1. Inspect all components prior to installation. If damage is found, please contact your distributor or WhisperKOOL Customer
Service at 1-800-343-9463.
2. Each evaporator unit requires a dedicated 115V, 15-amp circuit. The condensing unit requires a dedicated 230V single-
phase 15-amp circuit. Use a surge protector with the unit. Do not use a GFI (ground fault interrupter) line.
3. You are REQUIRED to install a drain line to remove condensation from each evaporator unit.
4. The warranty is not active until a warranty checklist has been received, reviewed, and approved.
5. 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.
6. WhisperKOOL requires that all split systems be installed by a certified HVAC-R technician only. NATE or equivalent is
recommended.
7. It is vital that the units be set apart and oriented so that the return air from one unit does not recirculate into the supply air of
the other unit.
If you encounter a problem with your WhisperKOOL system, please refer to the Troubleshooting Guide. If you have any further
questions or concerns, or need assistance, please contact WhisperKOOL’s Customer Service at 1-800-343-9463. Please be sure all

PREPARING THE WINE CELLAR
The performance and life of your system is contingent upon the steps you take in preparing the wine cellar. Improp-
erly 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 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 which we do not address.
Wall & Ceiling Framing
Build wine cellar walls using standard 2x4 or 2x6 boards and ceiling joists without violating local or state codes in
your area. As a general rule, the thicker the walls and the higher the insulation value, the more consistent your cellar
temperature will be.
Insulation
Insulation is REQUIRED in order to properly use WhisperKOOL products. It is vital that all walls and ceilings be
insulated to keep the cellar temperature as consistent as possible during the summer and winter months. Standard
berglass or rigid foam insulation is normally used in cellar construction; in some cases, “blown-in” insulation is used.
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, and the more consistent your wine cellar’s
temperature will be. Using higher R-values in insulation will lower your operating costs and WhisperKOOL unit run
time. (R-13 is the recommended minimum; R-19 is preferred for interior cellar walls, and R-30 for ceilings and exterior
walls.)
Vapor Barrier
Water vapor creates its own pressure, separate from the ambient air pressure, and will intrude into colder/drier
areas. A vapor barrier is REQUIRED in order to prevent the intrusion of water vapor and maintain the correct cellar
temperature and humidity. It is recommended that 6-millimeter plastic sheeting 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 cause 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.

Platinum Twin
Door and Door Seal
An exterior grade (1¾”) 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 system’s overall performance and lifespan. Make sure there
is a minimum of three (3) feet of horizontal clearance in every direction around the units (ve feet is ideal). 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.
NOTE: Avoid attempting to camouflage the units. This will restrict airflow and thus the system’s ability to work efficiently.
NOTE: For ducted systems, every 90° bend in the ducting
causes the system to lose 13 CFM of airflow.
Mounting the Evaporator Units
The evaporator units 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 units high in the room will create a consistently cool
environment by capturing the warm air and replacing it with cool air. Mounting the units low in the room will result in
a temperature variation in the room due to the units’inability to draw warm air from the ceiling of the cellar to the units
themselves, and cold air settling to the oor.
Wine Cellar
Keep Clear

Page 12 | 1-800-343-9463 PT 102417
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 unit’s 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.
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 less the electricity consumption.

Initial Start-Up
Set the thermostat to COOL and fan switch to AUTO.
Lower the set point to the desired cellar temperature. (A
temperature of 55°F is the recommended set point.) See
thermostat instructions for details.
Normal System Cycle
The thermostat should turn the cooling system on when
it senses a temperature one (1) degree higher than the set
point. See thermostat instructions for details.
Anti-Short Cycle
Most thermostats have a safety feature that will prevent
the condensing unit from cycling on and o within a short
period of time. During the anti-short cycle, the condensing
unit will typically remain o for 5-7 minutes. See thermostat
instructions for details.
Fan Operation
If the fan switch on the thermostat is in the AUTO position, it
will run only during the cooling cycle. If the fan switch on the
thermostat is in the ON position, the fan will continuously run
until the switch is set back to the AUTO position.
Anti-Frost
Systems equipped with a 24V thermostat conversion kit do
NOT have an anti-frost feature. To reduce the possibility of the
evaporator coil icing up, avoid setting the thermostat lower
than 55°F.
NOTE: To ensure correct system operation, the 24V thermostat
must be placed inside the wine cellar, preferably in a central
location away from any airow.
SYSTEM OPERATION
The cooling system is equipped with the hardware needed to support a 24-volt air conditioning thermostat (not included).

TROUBLESHOOTING GUIDE
Ice forming on the evaporator units
Possible cause Solution
Evaporator lters or coils are dirty Remove the lters and wash them, then clean the coils with a
vacuum. If coils are very dirty, use a spray bottle with a small amount
of liquid dish detergent or coil cleaner. Spray coils, let set for ve
minutes, then ush with fresh water.
There is something blocking the supply and/or return air Remove blockage
The evaporator fans are not turning on Call customer service for details on how to perform the bypass plug
test. If all components run correctly, and the system cools during the
bypass plug test, there is either an issue with the 24V
thermostat conversion kit or the thermostat. Contact customer
service for further action.
If evaporator units continue to ice Observe ice formation pattern. If only part way up the coil face, the
system could be low on refrigerant. If all the way up, the coils may be
dirty or airow is blocked.
The set point is too low Raise set point to recommended temperature of 55°F.
Unit does not run/power up
Possible cause Solution
Evaporator units are not plugged in Make sure the units are plugged into an outlet
