INTRODUCTION
Customer Service
Thank you for purchasing a CellarCool 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 visit
CellarCool.com.
Using the Manual
This manual is intended to assist in the proper maintenance and installation of the cooling system. In order to ensure the
longevity of your cooling unit, the equipment should be installed as outlined. 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 CellarCool Cooling System?
The CellarCool 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 fine wines. This system produces minimal in-
cellar noise and has the most lenient exhaust requirements.
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. The units are connected by a refrigerant line set and communication cable. 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
properly ventilated.
Temperature Setting
The system is designed to maintain a cellar temperature of 55°F as long as the ambient temperature does not exceed 120°F.

BEFORE YOU START
1. Inspect all components prior to installation. If damage or missing components are found, please notify CellarCool
Customer Service at [e-mail] within 30 days.
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. Communication cable (18-5 thermostat wire) must be ran between the condensing unit and the evaporator unit. Only 2 of
the communication wires will be used. For 24V thermostat equipped systems an 18-5 cable must be used to connect the
thermostat to the evaporator unit.
4. You are REQUIRED to install a drain line to remove condensation from each evaporator unit.
5. The warranty is not active until a warranty checklist has been received, reviewed, and approved.
6. 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.
7. CellarCool requires that all split systems be installed by a certified HVAC-R technician. NATE or equivalent is recommended.
8. 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 CellarCool system, please refer to the Troubleshooting Guide. If you have any further
questions or concerns, or need assistance, please contact CellarCool's Customer Service at [e-mail]. Please be
sure all testing has been completed prior to contacting Customer Service. Please have your results ready for your
representative.

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 effects.
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. 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 specific 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 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 fiberglass 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 infiltration 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 significantly 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 Airflow
Unobstructed airflow to and from the system is critical for the evaporator unit and condensing units overall performance
and lifespan. A minimum of 3 feet of clearance (5 feet 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 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
The evaporator unit must be mounted within 18' of the top of the room in order to achieve sufficient 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 floor.
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 system
should be used. This will compensate for the insulation loss
due to the lower insulating rating of glass.

Ambient Temperature Factor
The cooling system has the ability to cool a wine cellar efficiently to 55°F as long as the ambient temperature of the
area that it is exhausting to does not exceed 120°F. Therefore, you want to exhaust the condensing unit in a space which will
not exceed 120°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 affect 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 specific installation
WARNING! Allowing your system to operate in temperatures of 120° 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.

LIQUID-MEASURING THERMOSTAT SYSTEM (BOTTLE PROBE) - KDT
Our cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating probe con-tains a sensor
chip, which communicates back and forth with the thermostat. This results in a consistent temperature setting and
accuracy. Wine should be kept at a very precise, controlled temperature and humidity.
Setting up the Bottle Probe:
1. Locate an empty wine bottle.
2. Fill it 75% full with room-temperature tap water.
3. Place bottle probe securely into bottle as seen in Figure 1.
4. Place the wine bottle in your wine cellar. Ensure sensor tip is fully
submerged.
5. To ensure a consistent temperature, place bottle probe approximately three
(3) feet away from the air output and not in the flow of the air.
It is recommended that the bottle be placed in a central location of
your wine cellar. Avoid pulling too much on the probe cord. It may become
disconnected resulting in limited functionality of the unit.
Note: The thermostat can be set between 50–70°F.
Remember: The 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
reaching the optimum balanced temperature.
