WARNING
The evaporator unit (fan coil unit) must be insulated using the insulation blanket provided in
accordance with this manual. Refer to the insulation blanket installation instructions.
Failure to follow the instructions provided will result in a poor vapor barrier, water
damage, rust, and system corrosion which will void the warranty on your unit.
The evaporator unit (fan coil unit) must be insulated using berglass insulation (R13 or higher)
in addition to the provided insulation blanket. This includes the cavity between the ceiling
joists. A warm attic environment will reduce the capacity of the cooling system, as the system
will absorb heat from the attic in addition to the heat load from the wine cellar. This, in eect,
will signicantly reduce the cooling system’s ability to cool the wine cellar.
Failure to properly insulate the evaporator unit may cause condensation to form on the
surface of the housing and water damage to the surrounding structure, the cooling unit, and
possibly the wine cellar.
To avoid these issues, install the insulation kit and insulate the surface of the evaporator unit
that is located outside of the wine cellar using berglass insulation.
*Additional insulation is required!

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 1-855-235-5271 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 (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.

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 (fan coil unit) and the condensing unit.
4. A standard 18-5 thermostat wire must be run from the evaporator unit (fan coil unit) to the thermostat.
5. You are REQUIRED to install a drain line to remove condensation from the evaporator unit (fan coil unit).
6. The warranty is not active until a warranty checklist has been received, reviewed, and approved.
7. 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.
8. 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 assistance, please contact CellarCool’s Customer Service at 1-800-343-9463. Please be sure

* Sizing the Unit to the Room
There are several factors such as glass, stone, concrete, etc. which will change the required amount of BTUs needed to
properly cool your wine room. We strongly recommend utilizing the cellar wizard on the CellarCool website in order to
ensure you are selecting the proper cooling system for your application. Under-sizing your cooling unit can lead to pre-
mature failure and/or prevent the system from reaching the desired set temperature.

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. 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

CCM 062817
Page 12 | 1-855-235-5271
Unobstructed Airow
Unobstructed airflow to and from the system is critical for the system’s overall performance and lifespan. A
minimum of 3 feet of clearance around the unit is crucial (5 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.
Door and Door Seal
An exterior-grade (1¾”) door must be installed as a cellar door. It is very important that weather stripping is attached
to all four sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have an excellent
seal to keep the cool cellar air from escaping the cellar. If the door is not sealed properly, the cooling system may run
continuously, shortening its operational lifespan.
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 insulation rating
of glass.
Note: Avoid attempting to camouflage the unit. This will restrict
airflow, and thus the system’s ability to work efficiently.

CM 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
to which it is exhausting does not exceed 110°F. Therefore, you the condensing unit to exhaust in a space which will not
exceed 110°F, allowing for proper dissipation of the heat exhausted by the condensing unit. Without proper heat dissipa-
tion 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 system’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 the area or room and adversely aect the system’s 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.
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 lower the consumption of electricity.

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.
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).
