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 call us at 1-800-343-9463 or visit
CellarCool.com.
Using the Manual
This Owners 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 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 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 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 CellarCool system can be set at any temperature within the acceptable wine-aging range of 45°F to 67°F. It
is designed to cool up to 55°F cooler than the ambient temperature of the space to which the condensing unit is
installed.

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-insulated, beautiful, and protective wine cellars. CellarCool 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 CellarCool 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

Unobstructed Airow
Unobstructed airflow to and from the system is critical for the Evaporator Unit (Fan Coil Unit) and Condensing
Unit overall performance and life-span. A minimum three-foot clearance (five foot 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’s 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 contribute to 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 (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 CellarCool 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 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.
Note: If you are unsure about having adequate ventilation in your install location, please
contact us to assess your specic installation at [e-mail] 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:
When power is applied to the unit, the control will briey
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 fans turning on.
Set Point:
The set point is set from the factory (CellarCool) at 55°. It
can be adjusted by the customer between 50° and 70° in
one degree increments.
Cooling Operation:
Cooling is activated once the Air Sensing Probe senses
a temperature that is 4° greater than the set point. The
controller then energizes the solenoid relay which activates
the solenoid. The evaporator fans operate with the
compressor. The unit provides cooling until the Air Sensing
Probe senses the set point. At this point the solenoid relay
is de-energized which stops the ow of refrigerant through
the evaporator coil. The compressor will continue to run
until the low side pressure reaches 5 psi. The evaporator
fans will continue to run for 1 minute to re-evaporate any
moisture from the evaporator coil.
Humidity Features:
The FDC parameter can be increased to allow the evaporator
fans to run for a longer period of time after the compressor
turns o, allowing more moisture to be re-evaporated into
the cellar.
Defrost/Anti-frost:
When the evaporator probe senses a temperature of
26 degrees for 5 minutes, the unit will go into Anti-frost
mode. This will shut down the compressor and allow the
evaporator fans to run to evaporate any frost accumulation
on the coil. The compressor will remain o until the
evaporator coil reaches 40°, or for a maximum of 10 minutes.
The unit will then return to normal operation.
If the evaporator is not above 26 degrees after the anti-frost
sequence has ended, the red error light will display in the
upper right corner. Alarm “Ad3”will be recorded in the alarm
folder, meaning that the anti-frost sequence ended based
on time. The unit will run for 5 minutes and then enter
another Anti-Frost cycle. This sequence will continue until
the evaporator temperature increases above 26°.
“Def” will be displayed during anti-frost. If the anti-frost
sequence is less than 5 minutes, the control will not allow
the compressor to start until 5 minutes has elapsed. This is
to prevent short cycling of the compressor.
Holding down the up button for approximately ve seconds
manually starts the Anti-frost sequence, but only if the
evaporator is below 40 degrees (defrost end temperature).
If the evaporator is above 40 degrees, the display will blink
three times and continue normal operation.
Display:
The Air Sensing Probe temperature is displayed by default.
“Def” is displayed during anti-frost. The Air Sensing Probe
and evaporator probe temperatures can all be accessed
by pushing the set button and scrolling through PB1 (Air
Sensing Probe) and PB2 (evaporator probe).
Safety Features:
Once the solenoid relay is de-energized the controller must
wait 5 minutes before re-energizing the relay. This prevents
the compressor from repeatedly turning o and on. If the
unit is calling for cooling during this time, the compressor
symbol will blink indicating that cooling is needed but the
control is waiting for the anti-short cycle delay.
In the event of a faulty Air Sensing Probe, the compressor
will cycle o for 10 minutes and on for 40 minutes. E1 will
will be displayed on the screen.
Alarms:
If the air temperature reaches 10 degrees above the set
point, a red light will blink in the upper right corner of the
display. The set button can then be pressed to reach the
alarm menu. The menu will display “AH1” indicating a high
bottle temperature. The same thing will happen if the air
temperature reaches 10 degrees below the set point, except
the alarm will read“AL1”. These alarms will not display for the
rst 10 hours after the unit is turned on to allow the cellar
to reach temperature. They will also wait one hour after an
anti-frost cycle before displaying.
In the event of a faulty evaporator probe E2 will ash on the
screen intermittently. The red alarm light will be displayed
in the upper right corner. The unit will go through one anti-
frost sequence every 24 hours.
Press the set button and enter the Al folder to view any
current alarms that are not ashing on the display.

Condensate Pump Kit
The condensate pump kit is designed as an automatic condensate removal pump for water dripping out of our
evaporator units’ drain line. The pump is controlled by a float/switch mechanism that turns the pump on when
approximately 2-1/4”of water collects in the tank, and automatically switches off when the tank drains to approximately
1-1/4”. The condensate pump kit allows the excess condensate to be pumped up to 20ft away from the unit.
