PREPARING THE WINE CELLAR
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.

Page 8 | 1-855-235-5271 WM&FD 021014
Unobstructed Airow
Unobstructed airflow to and from the system is critical for the system’s 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 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.
Door and Door Seal
An exterior grade (1 3/4”) door must be installed as a
cellar door. It is very important 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 seal to keep the cool cellar air from escaping out
of 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.

www.cellarcool.com | Page 9
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 [email protected] 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 Snow Flake symbol will
be displayed (if unit is calling for cooling). There may
be a brief delay prior to the evaporator fan turning on,
as the fan will not turn on until the evaporator probe
temperature drops below 70°F. When the evaporator
fan is activated the Fan symbol will be displayed. The
temperature control feature for the evaporator fan is
a feature applicable to CellarCool. This is the Advance
Product Safety Technology (APST), which ensures that in
the possible event of a cooling deciency, the heat from
the indoor fan will not raise the temperature of the wine
cellar, which could otherwise have an adverse eect on
the wine aging process.
Normal System Cycle
After the Air Sensing probe has reached the set point
(all units are shipped with the set point of 55°F and a
dierential of 1°F), the compressor and the condenser
fan will turn o, but the indoor fan will continue to run
for about 5 minutes, which is a feature of the CellarCool
Humidity Management (WHM) system. The WHM is
an adjustable feature which allows the customer the
convenience of managing the humidity enhancement of
their wine cellar. The WHM is one of the many Customer
Preference Selection features which allow the customer
the ability to ne tune the controls.
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 to prevent short cycling of 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 defrost cycle
every 4 hours. During the defrost cycle, the indoor fan
will provide air ow across the indoor coil, which will
evaporate any frost accumulation.
Low Ambient Conditions
If the condensing unit is installed outside (which will
allows the condenser to be exposed to low ambient
temperatures), the condenser fan may cycle on and
o. The purpose of the fan cycling is to maintain the
system high side pressure, which will ensure an adequate
refrigeration process.
Air Sensing Probe Failure Protection
In the event that a Air Sensing probe should fail, the APST
(Advance Product Safety Technology) will automatically
transition the Refrigeration Compressor cycles to a pre-
determined time series (based on detailed laboratory
testing), which will ensure that the product is kept within
the safe range.
Remote Control Panel (standard on ducted units)
The remote keypad is designed to give the user the
ability to monitor and change cellar conditions when the
evaporating unit is placed in a remote location outside of
the cellar.

CPSM Mode Press the“Set”and the “Down Arrow” buttons simultaneously, for 3-5 seconds, and you will
access the“Customer Preference Selection Mode” (CPSM). The CPSM allows the customer to
“Fine Tune”the Control Operating System to their applicable choice.
The following CPSM options are available for adjustment:
Fon – Humidity Management Enhancement: This parameter is normally set at 0, which
should provide adequate relative humidity for the cellar.
• An increase in this parameter will increase the Humidity Enhancement (%RH), and a
decrease in the parameter will decrease Humidity Enhancement (%RH).
• Adjustments should be made in increments of 5, with a maximum of 15, and a minimum
of 0.
• After any adjustment to Humidity Enhancement, you should wait a minimum of three
days before making any additional adjustments. This will allow the cellar sucient time
to acclimate to the new setting.
Fof - Humidity Management Enhancement: This parameter is normally set at 15. This
parameter should not be adjusted, as it simply provides an OFF cycle time for the fan,
during the compressor OFF cycle. However, the parameter is located within the CPSM as a
convenience to the customer, should it need to be adjusted. CCT - Cellar Pre-Chill Duration:
This parameter is set to 6 hours, but can be changed between 0-23.5 hours.
Con/Cof – Compressor On time (Con) and O time (Cof) with a Probe 1 failure/Alarm. These
parameters are set at Con 40 min/Cof 10 min. In the event that there is a Probe 1 failure/
Alarm, the compressor/refrigeration system automatically starts a predetermined ON/OFF
cycle, which is controlled by the Con and the Cof parameters. The customer can adjust these
parameters to maintain the desired Air temperature.

Exterior Grille
Protects the evaporator unit from the weather elements when placed on the exhaust side.
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.
Ducting Kit
This kit allows the exhaust side of the unit to be ducted to an area (most cases outside) that the additional heat will not
matter.
