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 call us at 1-800-343-9463 or visit cellarcool.com.
Using the Manual
This owner’s 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 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 1-800-343-9463
1. Inspect all components prior to installation. If damage is found, please contact your distributor or CellarCool Customer
Service at 1-800-343-9463.
2. The evaporator unit and condensing unit each require a dedicated 115V, 20-amp circuit. Use a surge protector with the unit.
Do not use a GFI (ground fault interrupter) line.
3. The evaporator unit and condensing unit require no communication lines unless the system is equipped with a Cold Weather
Start Kit. If the system is equipped with a Cold Weather Start Kit, a low-voltage 18-2 thermostat wire will need to be run
between the evaporator unit and the condensing unit.
4. You are REQUIRED to install a drain line to remove condensation from the 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 only. NATE or equivalent is recommended.
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 technical assistance, please contact CellarCool’s Customer Service at 1-800-343-9463. Please be

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-insu-
lated, 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 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 CellarCool 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 CellarCool 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.
PREPARING THE WINE CELLAR

Page 10 | 1-855-235-5271 WM&FD 030118
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 CellarCool 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 unit (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 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 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.

WM & FD SERIES

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 [e-mail] or 1-855-235-5271.
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.

LIQUIDMEASURING THERMOSTAT SYSTEM BOTTLE PROBE
CellarCool cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating bottle 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. By measuring the
liquid temperature rather than air, the unit will operate 75–80% of the time.
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 bottle off to the side of the unit in your wine cellar, with the probe level.
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 50–67°F.
Remember: The CellarCool 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.

SYSTEM OPERATION
Initial Start-Up
When the unit is powered on, the snowake symbol will ash
four times, indicating that the controller is calling for cooling.
The snowake symbol and fan symbol will then remain
steadily illuminated, indicating that the system is operating.
Set Point
The set point is preset at the factory at 55°F. It can be adjusted
by the customer to temperatures between 50 and 67°F (in 1°F
increments).
Indoor Fan Operation
The indoor fan will run when the controller is calling for cool-
ing and turn o once the cooling cycle has ended. If, however,
the customer wishes to raise the relative humidity of the wine
cellar, the“fan on” (Fon) and“fan o” (FOF) functions may be
adjusted.
The FOF cycle should be shortened rst. This will reduce the
amount of time that the fan remains o following a cooling
cycle. The Fon setting may then be lengthened to allow the
fan to run longer and reintroduce a portion of the moisture
removed during the cooling process back into the wine cellar.
For more information about Fon/FOF parameters, refer to the
Controller Functions chart.
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.
This allows the pressure in the refrigeration system to equalize
prior to starting the compressor.
Anti-Frost Cycle
The Anti-Frost Cycle is a precautionary measure, as icing or
frosting of the coil does not occur during normal operation.
The system will go through a Anti-Frost Cycle every 4 hours.
During the Anti-Frost Cycle, the indoor fan will provide air
ow across the indoor coil, which will evaporate any frost
accumulation.
Operation in Low Ambient Temperatures
If the condensing unit is installed outside (where the unit may
be exposed to low ambient temperatures), the fan may cycle
on and o. The purpose of the fan cycling is to maintain the
system’s high side pressure, which will ensure an adequate
refrigeration process.
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 predetermined timed
ON/OFF series (based on detailed laboratory testing), which
will ensure that the product is kept within a safe temperature
range.
Digital Keypad
The keypad on the controller is designed to give the user the
ability to adjust parameters such as set point and Fon/FOF
settings. (See Customer Preference Selection Mode chart for
details.)
The bottle probe temperature is displayed by default.“Def” is
displayed during the Anti-Frost Cycle. The bottle probe and
evaporator probe temperatures can be accessed by pushing
the SET button and scrolling through“PB1” (bottle probe), and
“PB2” (evaporator probe).
Safety Features
Once the compressor relay is de-energized, the controller
must wait 5 minutes before reenergizing 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 bottle probe, the compressor will cycle
o for 10 minutes and on for 40 minutes. “P1” will be displayed
on the screen.
Alarms
See “Alarm Codes” in the Controller Functions chart.

Button/Symbol Normal Functions
ON/OFF The ON/OFF button allows the customer the convenience of turning the refrigeration system ON or
OFF from the keypad. This feature does not disconnect power from the unit. In order for the power
to be shut o from the unit, the power cord must be disconnected from the power source.
To power o the system, press the ON/OFF button. A number will appear, followed by three dashes
( - - - ), which will then disappear and be replaced by the word “OFF”and the orange clock symbol.
After three seconds, the “OFF” disappears, leaving only the clock icon.
To power the system on, press the ON/OFF button. The snowake symbol will ash four times, indi-
cating that the system is calling for cooling. The snowake symbol and fan symbol will then remain
steadily illuminated once the system is operating.
UP/DOWN
ARROWS
Use these buttons to scroll up or down the CPSM (Customer Preference Selection Mode) menu.
They can also display the highest and lowest temperatures sensed by the bottle probe. This feature
allows the customer instant access to recorded bottle probe temperature data. It can be easily reset
to reect current temperatures.
1. Press the UP ARROW or the DOWN ARROW once, and the highest or lowest temperature (Hi/Lo)
sensed by the bottle probe will be displayed.
2. To reset the Hi/Lo sensor, press and hold the SET button when the Hi/Lo value is shown on the
digital keypad. Continue to hold the SET button until“rSt” appears on the display and then
blinks. This will erase the past recorded “Temperature Data History” and start recording from the
current time and temperature. Temperatures displayed reect bottle probe temperatures from
that point in time onward.
3. The Hi/Lo feature should be reset at initial start-up and after the cellar or cabinet has reached its
normal operating temperature, generally 55°F.
4. To lock the controller, press and hold the UP and DOWN ARROW buttons simultaneously until the
code“POF”appears. The controller is now locked. You may still view the Hi/Lo temperature data
by pressing the UP or DOWN ARROW buttons individually. To unlock the controller, press and
hold the UP and DOWN ARROW buttons simultaneously again. The code “PON”should appear.
The controller is now unlocked.
CELLAR PRE-CHILL
(CPC)
The CPC feature is activated by pressing the UP ARROW button for 3-5 seconds. The CPC logo (a
snowake with an arrow around it) will appear on the digital display. The CPC feature can be termi-
nated by pressing the UP ARROW button for 3-5 seconds. The feature will also self-terminate after 6
hours.
1. The CPC feature may be used to pre-chill the cellar prior to loading it with warm product. Once
the feature is activated, the system will run for the next 6 hours regardless of the temperature
inside the wine cellar. After the 6-hour time period expires, the set point will automatically return
to the original set point of 55°F (or whatever the customer has set).
2. The CPC feature can be conveniently adjusted to the customer’s specic needs by accessing “Cus-
tomer Preference Selection Mode”(CPSM). See CPSM instructions.

CUSTOMER
PREFERENCE
SELECTION
MODE
Customer Preference Selection Mode (CPSM) permits customers to ne-tune the control operating
system of their WhisperKOOL unit. The CPSM menu is accessed by pressing the SET and the DOWN
ARROW buttons simultaneously for 3-5 seconds.
The following CPSM options are available in the menu:
HY - bottle probe dierential: This is measured in degrees Fahrenheit. If set to 1, and your unit’s set
point is 55°F, then the system will begin cooling when the bottle probe temperature reaches 56°F.
Pr2 - advanced options: This menu is only accessible using a password and is not available for
adjustment.
Prd - probe display: This allows you to briey view the temperature of the evaporator coil probe.
Adr - instrument address: Deactivated.
Under normal conditions, after the set point has been reached, the fan begins an ON/OFF cycle. This
will continue until the system returns to cooling mode.“Fan o” (FOF) comes rst, followed by “fan
on” (FOn).
FOF - Humidity Management Enhancement (“fan o”): This setting controls how long the fan
stays o after the set point has been reached. It is preset at 15 minutes. This setting should not be
adjusted, as most properly constructed wine cellars retain an ample amount of humidity during
the “fan o” cycle. If, however, you wish to decrease the duration of the “fan o” cycle (in order to
increase the wine cellar’s relative humidity), you can adjust this setting in the CPSM menu.
FOn – Humidity Management Enhancement (“fan on”): The“fan on”time is preset to zero
minutes. This keeps the relative humidity of the wine cellar at a stable level. If, however, you wish
to raise the relative humidity (Humidity Management Enhancement) of your wine cellar, you can
increase the duration of the“fan on”cycle in increments of ve (5, 10, or 15 minutes). After making
any adjustment to the“fan on”cycle, you should wait a minimum of 3 days before making any
additional adjustments. This will allow the cellar sucient time to acclimate to the new Humidity
Management Enhancement setting.
rEd - remote display: This allows you to choose which probe temperature will be permanently
shown on the display. You can select either “PB1” (bottle probe) or“PB2” (evaporator coil probe).
Lod - local display: Nonfunctional.
Con/Cof – “compressor on” and “compressor o” time: In the event that there is a P1 failure/alarm
(see page 36, the compressor/refrigeration system automatically starts a predetermined ON/OFF
cycle, which is controlled by the preset “compressor on”and “compressor o” times. The compressor
is automatically set to be“on” for 40 minutes, and“o” for 10 minutes . The customer can adjust
these ON/OFF times in order to maintain the desired temperature in the wine cellar.
CCt – Cellar Pre-Chill Duration: This option is normally set at 6 hours, but can be set by the
customer for 0 to 23.5 hours.
