What is the CellarCool SL2500 Cooling System?
The CellarCool SL2500 system is a specialized refrigeration unit designed for one purpose: to maintain the optimal
temperature and humidity levels conducive to the proper storage and aging of ne wines. It is a self-contained cooling
unit designed to be used as a forced-air, through-the-wall unit.
How Does the CellarCool SL2500 Work?
The CellarCool SL2500 cooling system is especially designed to maintain optimal conditions for wine storage and aging.
The system is specially designed for slow cooling, as this greatly reduces the amount of humidity removed from the
cellar.
Temperature Setting
The CellarCool SL2500 unit can be set at any temperature within the acceptable wine-aging range of 45°F to 67°F. It is
designed to create up to a 30°F temperature dierential between the wine cellar and the space to which it is exhausting.

* Sizing the Unit to the Room
The specication chart will provide information on the unit’s cooling capacity. There are circumstances in which a cellar design may
require a larger unit due to preexisting design restrictions. Certain building materials such as glass, stone, or concrete may seem
adequate but do not oer the insulation capacity required to maintain the optimum temperature for storing wine. We recommend
purchasing a unit with a larger capacity to compensate for these design limitations. Undersized cooling units can lead to premature failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.

PREPARING THE WINE CELLAR
The performance and life of your system is contingent upon the steps you take in preparing the wine cellar.
Improperly preparing your enclosure or incorrectly installing your unit may cause unit failure,
leaking of condensation, and other negative side eects.
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 specic needs which we do not address.
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 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.)
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 inltration 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 signicantly 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

Mounting the Unit
The unit must be mounted within 18 inches of the ceiling 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 (a) the unit’s inability to draw warm air down from the ceiling and (b) cold air settling to the floor.

Keep Clear
Exhaust Area
Unobstructed Airow
Unobstructed airflow to and from the unit is critical to the unit’s overall performance and lifespan. Make sure there is a
minimum of three (3) feet of horizontal clearance in every direction around the unit (five 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 unit’s ability to work efficiently.
Door and Door Seal
An exterior-grade (1¾”) door must be installed as a cellar door. It is very important that weather stripping be attached to all four
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. If the door does not seal properly, the unit will run continuously.

SL2500
Ventilation
The necessity of dissipating heat away from the unit is critical to the unit’s performance and cannot be overstated. As the unit
operates and cools, a greater amount of heat is generated on the exhaust side of the unit. Adequate ventilation is required in
order to dissipate heat away from the unit. If ventilation is inadequate, the exhaust will heat up the area or room and adversely
aect the unit’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 rear of the unit. If you install a vent fan, however, you must have a fresh air inlet as well.
Note: If you are unsure whether you have adequate ventilation in your installation location, please
contact us to assess your specic installation at [email protected] or 1-855-235-5271.

Ambient Temperature Factor
The cooling system has the ability to cool a wine cellar eciently to 55°F as long as the ambient temperature of the area that it
is exhausting to does not exceed 85°F. Therefore, you want to exhaust the unit in a room which will not exceed 85°F, preferably
75°F. Otherwise, the unit will not have the capacity to keep the wine at a desirable 55°F.
WARNING! Allowing the unit to operate in high ambient temperatures for extended
periods of time will greatly decrease the life of the unit and void your warranty.
Drain Line
All units come with a drain line for additional removal of excessive condensate. This is a backup system for the evaporator. You
are REQUIRED to install the drain line attachment. During operation, the cooling unit will strip excess water from the air in order
to maintain the proper level of humidity within the cellar. The condensate evaporator will heat and dissipate the excess moisture
through the rear of the unit. However, in extreme humidity, additional condensate will be created. High-humidity air has less
capacity to absorb additional moisture through the exhaust of the unit. The drain line will prevent overflow and leaking by
allowing for the discharge of the additional condensate. CellarCool carries a condensate pump kit, which allows the excess
condensate to be pumped up to 20 feet away from the unit.

Electrical Needs
The SL2500 system requires a dedicated 115V, 20-amp circuit. The unit draws a large amount of amps during its
initial startup. By designating a dedicated circuit breaker, you will guarantee that the unit has enough power to run
eectively. Contact an electrician for assistance with the installation of this dedicated electrical circuit:
• Match the electrical outlet to the plug provided on the CellarCool unit.
• Provide a dedicated circuit and wiring for the unit.
Electrical Outlet
The unit is equipped with a 12-foot power cord located on the evaporator side of the unit. Plug your CellarCool unit
into a surge protector or power conditioner. Power surges and spikes can damage sensitive electrical equipment.
CellarCool recommends plugging the unit into a surge protector or power conditioner in order to protect your system.
As outlined in our terms and conditions, power surges and spikes are not covered under warranty.
WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.

LIQUIDMEASURING THERMOSTAT SYSTEM BOTTLE PROBE
CellarCool cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating bottle probe
contains a sensor 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 controller can be set between 45-67°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 Startup
When power is applied to the unit, the snowflake symbol will
be displayed (if unit is calling for cooling). There may be a
delay of up to 60 seconds before to the evaporator fan turns
on. When the evaporator fan is activated, the fan symbol will
be displayed.
SL2500
Display
The bottle probe temperature is displayed by default. “Def” is
displayed during an Anti-Frost Cycle. The air-sensing probe
and evaporator probe temperatures can be accessed by
pushing the SET button and scrolling through “PB1” (bottle
probe), and “PB2” (evaporator probe).
APST (Advance Product Safety Technology) is a temperature
control feature for the evaporator fan that comes standard
with all CellarCool units. APST ensures that, in the event of a
cooling deciency, the heat from the indoor fan will not raise
the temperature of the wine cellar, which could otherwise
have an adverse eect on the wine-aging process.
Set Point
The set point is preset at the factory at 55°F. It can be adjusted
by the customer between 45–67°F in one-degree increments.
Anti-Short Cycle
The Anti-Short Cycle ensures that the compressor will remain
o for a period of three minutes after the unit has reached
the set point to allow the pressure in the refrigeration unit to
equalize prior to starting the compressor.
Anti-Frost Cycle (defrost)
When the evaporator probe senses a temperature of 25°F for
ve minutes, the unit will start an Anti-Frost Cycle. This will
shut down the compressor and allow the evaporator and
condenser fans to run to evaporate any frost accumulation on
the coil. The compressor will remain o until the evaporator
coil reaches 40°F, or for a maximum of ten minutes. The unit
will then return to normal operation.
Safety Features
Once the compressor relay is de-energized the controller must
wait ve 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.
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 pre-determined time
series (based on detailed laboratory testing), which will ensure
that the product is kept within a safe temperature range.

PREFERENCE
SELECTION
MODE
Customer Preference Selection Mode (CPSM) permits customers to ne-tune their unit’s operating system. The
CPSM menu is accessed by pressing the SET and DOWN ARROW buttons simultaneously for 10-15 seconds.
The following CPSM options are available in the 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
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 sucient time to
acclimate to the new Humidity Management Enhancement setting.
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, you can adjust this setting in the CPSM menu.
CCs – Cellar Pre-Chill Set Point: This parameter is preset at 52°F, but can be adjusted to a set point between
45°F- 67°F.
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.
Con/Cof – “compressor on” and “compressor o” time: In the event that there is a P1 failure/alarm (see
previous page), 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.
