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 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.

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. Each evaporator unit requires a dedicated 120V, 15-amp circuit. The condensing unit requires a dedicated 220V single-
phase 15-amp circuit. Use a surge protector with the system. Do not use a GFI outlet or breaker.
3. The 18000 condensing unit requires a dedicated 230V, 15-amp, single-phase circuit. Use a surge protector with the unit. Do
not use a GFI (ground fault interrupter) line.
4. The 24000 condensing unit requires a dedicated 230V, 25-amp, single-phase circuit. Use a surge protector with the unit. Do
not use a GFI (ground fault interrupter) line.
5. 18-5 communication cable is required between the evaporator and condensing units.
6. You are REQUIRED to install a drain line to remove condensation from the evaporator unit.
7. The warranty is not active until a warranty checklist has been received, reviewed, and approved.
8. 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.
9. WhisperKOOL requires that all split systems be installed by a certified HVAC-R technician only. NATE or equivalent is
recommended.
10. It is vital that the units be set apart and oriented so that the supply air from one unit does not recirculate into the return
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
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. Improperly preparing
your enclosure or incorrectly installing your unit may cause unit failure, leaking of condensation, and other negative side eects.
Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build well-
insulated, beautiful, and protective wine cellars. We have 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 38 x 89 mm or 38 x 140 mm 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 our 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 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.
Unobstructed Airow
Unobstructed airow to and from the system is critical for the evaporator unit and condensing units overall performance and
lifespan. A minimum of 1 metres of clearance (1.5 metres is ideal) on all sides 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 ecient the system will operate.
Note: Avoid attempting to camouage the unit. This will restrict airow and thus the systems ability to work eciently.
It is highly recommended that you obtain the assistance of a
wine storage professional.

PREPARINGTHEWINE CELLAR, CONTINUED
Mounting the Evaporator Unit
The evaporator unit must be mounted within 0.5 meterof 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.
Door and Door Seal
An exterior grade (44 mm) 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 system should be used. This will compensate for the insulation loss due to the lower insulating rating of glass.
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 ventila-
tion 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 system’s ability to cool. Avoid installing the condenser in a closet or other small rooms and
spaces. This will cause the system to overheat and void the warranty.
Note: If you are unsure about having adequate ventilation in your install location, please contact us to assess your specic installa-
tion.
AmbientTemperature Factor
The cooling system has the ability to cool a wine cellar eciently to 13°C as long as the ambient temperature of the
area that it is exhausting to does not exceed 49°C. Therefore, you want to exhaust the condensing unit in a space which will
not exceed 49°C. Otherwise the system will not have the capacity to keep the wine at a desirable 13°C .
WARNING! Allowing your system to operate in temperatures of 49°C or
above 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.

DUCTING OVERVIEW
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork to minimize
cooling losses, prevent sweating, and reduce noise. Use ductwork on the condenser section to redirect or absorb sound, bring in
outside air to the unit inlet, and/or exhaust the hot air.
Note: Do not exceed a total of 25 feet for each length of ductwork run
and a combined total of 50 feet for both the supply and return lengths.
Avoid crimping the flexible ducts. This reduces airflow, causing the unit to operate improperly. Be sure all ductwork and outer
surfaces in contact with the airflow are insulated and have a vapor barrier on the outside. Uninsulated supply and return ducts may
cause bare, exposed metal surfaces to sweat, further degrading the insulation and equipment cooling capacity.
Do not allow sharp turns to squeeze or decrease the inside
diameter of the flexible ducting.
General duct recommendations:
• Provide support for the flexible duct to prevent sags and bends.
• Quantum 18000 and 24000 duct size: 14” supply and return
• Register size: 14” x 14”
• Filter size: 14” x 14” (MERV 4)
• Stretch out the duct to make a smoother interior which reduces air resistance.
• Maximum duct length is 25 feet supply, and 25 feet return.
• For 90° bends, use a 90° adjustable elbow.
• No more than two 90° bends on each duct. Sweep 90° bends are recommended rather than sharp 90° bends.
• Generously apply duct sealant to all metal seams to fill in gaps that can leak air. Allow sealant to dry until
firm to the touch before applying fiberglass insulation.
• Do not squeeze or reduce the inside diameter of the ducts, as this will reduce airflow.
• Use short and straight ductwork where possible.
• Check that all fan blades move freely.
• Keep air paths free of loose foreign objects and debris.
• Locate the supply and return grilles inside the cellar to create an airflow pattern that maximizes air
circulation in the room. Avoid short circulation of the air.
DO NOT:
• Install through-the-wall return air grilles at floor level where they will collect dust from the floor.
• Locate the supply or return air grille where it is blocked by bottles, boxes, or cases.
