I. Prior to Installation
Test the unit before installing it.
1. Remove the unit from the box. SAVE THE BOX AND PACKING MATERIALS.
2. Remove any materials that have been packed inside the exhaust cavity
3. Plug in the power cord and let the unit run on a hard, flat surface
4. Check to make sure that both fans (one at the top and one at the bottom of
the cooling unit) are spinning.
5. Check that the cooling unit is discharging cold air from the bottom (it should
be approximately 5.6°C colder than the temperature on the digital display)
Make sure that the exhaust panel is installed in the correct position – it should
cover either the TOP or the REAR exhaust vent:
oTOP VENT CONFIGURATION::
If the hot air will be discharged
through the TOP of the cellar,
install the exhaust panel on the
BACK of the cooling unit (as

Cooling Capacity*
Estimated thermal loads for various size cellars, with various insulations, various
ambient temperatures and various cellar temperatures, are shown in the table below.
To figure out whether a CellarPro unit will work in your space, make sure that the
cooling unit’s BTUH for a given cellar temperature is equal or greater than the
thermal load shown. The bold numbers are within the capacity of both units. The
unbold numbers in black are within the capacity for the 1800XT 60Hz but not for the
1800XT 50Hz. The numbers in red are beyond the capacity of both cooling units.

*Please note: Glass door(s) in the wine cellar have much lower insulation values
than insulated walls, which will increase the heat load and therefore reduce the
cooling unit’s capacity.

Ambient Environment
CellarPro cooling units are designed to operate in ambient temperatures between
10.0°C and 29.4°C. They are designed for internal use only, and are not designed for
exposure to the exterior.
CellarPro cooling units are designed to maintain temperatures inside the cellar up to
16.6°C below the ambient temperature of the condenser air intake. For example, if
the ambient temperature of the condenser air intake is 29.4°C, the cooling unit
should be able to maintain temperatures of 12.8°C inside the cellar. Similarly,
CellarPro cooling units do not have heating elements, so if temperatures inside the
cellar drop below proper wine storage temperatures, the cooling unit cannot create
heat inside the cellar.
Proper temperatures are maintained by transferring heat from inside wine cellars
and exhausting heat through the top (top-vent) or rear (rear-vent) of the cooling units.
Insulation
CellarPro cooling units are designed to be installed inside wine cellars that have
proper insulation, moisture barriers and an airtight seal from the environment
outside the cellar.
Interior walls and floor
should have a minimum of
R-11 insulation, and a vapor
barrier on the warm side of
the insulation. The ceiling
should have a minimum of
R-19 insulation and a vapor
barrier on the warm side of
the insulation. Doors also
should be insulated and
tightly sealed with weather
stripping around the
perimeter of the door.
Surface-mounted fixtures
are recommended over
recessed lighting, which can
allow air to leak into the
cellar.
It is critical that all walls, joints, doors and windows, electrical outlets and/or
switches, pipes, vents and light fixtures be sealed to prevent air and moisture from
entering the cellar. If there is a leak in the cellar, the cooling unit will build up excess
condensation that eventually may damage the internal components and shorten the
life of the cooling unit, and may cause water to leak from the cooling unit.

7
We offer a Wine Cellar Modification for cooling
units that will be installed in wine cellars (as
opposed to wine cabinets.) The Wine Cellar
Modification provides a fitting and condensate
tube at the back of the cooling unit to relieve
excess moisture that may condense inside the
cooling unit. For installations in warm
environments and/or cellars without airtight
seals, we strongly recommend this
modification. However, the modification does
not replace the requirement for a cellar to have proper insulation, moisture barriers
and airtight seals from the environment outside the cellar.
If your cooling unit has the wine cellar modification, please make sure that the tube
has a condensate trap that is slightly filled with water, as follows:
As shown above, the drain line should drop, then rise (but stay below the height of
the fitting), and then drop again into a drain or bucket. Then, fill the trap with water.
The condensate trap will allow any excess moisture inside the cooling unit to
overcome the static pressure and flow out of the drain line.

8
Installation
CellarPro cooling units are designed to be installed THROUGH THE WALL. A hole
should be cut 0.25”(6.4mm) larger than the dimensions (W x H) of the cooling unit.
Horizontal braces should be installed between the studs below and above the cooling
unit. If the studs in the wall must be cut to accommodate the width of the cooling
unit, vertical braces also should be installed on either side of the cooling unit.
CellarPro cooling units must always be mounted in the upright position and located
as close to the ceiling as possible inside the cellar. As warm air rises to the top of the
cellar, the cooling unit pulls the warm air through the evaporator coils and removes
the heat from the warm air. Once cooled, the cold air is discharged from the bottom
of the cooling unit and circulates downward through the cellar.
The rear of the cooling unit should be slightly lower than the front of the cooling unit
(ie the cooling unit should be tilted backwards slightly), so that excess condensation
won’t drip through the evaporator fan cavity. The rear of the cooling unit should be
supported by the wall through which it is installed, and should be flush with the wall.
Assuming 4.5”(114mm) interior wall thickness, the front 12”(305mm) will be inside
the cellar. The front of the cooling unit can be mounted using optional mounting clips
(available for purchase from CellarPro), as follows:

9
Alternatively, the front of the cooling unit can be supported by a shelf and a diagonal
brace. The shelf can be up to 13.25”(337mm) inches wide, and should be
positioned on the right side of the cooling unit so that it doesn’t restrict the exhaust
vent below the cooling unit, as follows:
Once the cooling unit is installed, all cracks and gaps between the cooling unit and
the cellar should be sealed. We provide butyl tape (shipped in the cavity of the
exhaust vent) for sealing these gaps. The butyl tape becomes pliable by rolling it in
your hands. Pay particular attention to the seams on the back of the cellar (top and
rear vent configurations) and the seams at the top of the cellar (top-vent
configuration).

10
Ventilation
OUTSIDE THE CELLAR
Proper ventilation is critically important for the proper operation of your CellarPro
cooling unit. The CellarPro cooling unit creates a significant amount of hot air, which
must be exhausted into an appropriately-sized space in order for the heat to
dissipate. If the space is constrained and/or too small, the heat will not dissipate
and the cooling unit will end up recirculating hot air. If this happens, the cooling
unit’s ability to create cold air inside the cellar will be compromised.
1. Condenser Air Intake. The condenser coils are located at the rear of the cooling
unit. These coils require access to cool air in order for the cooling unit to produce
cool air. In general, the cooling unit will be able to produce cold air that is 16.6°C
below the temperature of the condenser air intake. The cooling unit must be
installed so that, after its installation, there is access to the condenser coils at the
rear of the cooling unit for periodic cleaning of the coils.
2. Condenser Air Exhaust. Condenser air can be exhausted either through the top or
the rear of the cooling unit. CellarPro units have interchangeable vent panels that
can be swapped between the top and the rear of the cooling unit to match the
configuration of your cellar and exhaust space. The hot air exhaust cannot be ducted
without an inline fan to augment the airflow inside the duct.
Rear vent configuration (most common): in this configuration, the panel is
attached to the top of the cooling unit and hot air is freely exhausted from the
rear of the cooling unit into the exhaust space, which should have the same
space capacity as the wine cellar. (eg, if the cellar is 8.50 m3, the exhaust
space also should be 8.50 m3.)In addition, this configuration should have
102-152mm of unobstructed clearance directly behind the cellar.
Top-vent configuration (less common): in this configuration, the panel is
attached to the rear of the cooling unit and hot air is freely exhausted from the
top of the cooling unit into the exhaust space. If the exhaust space is shared
with the rear of the cooling unit, it should have the same space capacity as
the wine cellar (eg, if the cellar is 8.50 m3, the exhaust space also should be
8.50 m3.).
INSIDE THE CELLAR
CellarPro cooling units are designed to turn on when the temperature near the ceiling
inside the cellar exceeds the Minimum Set Point plus the Temperature Differential,
and turn off when the temperature inside the cellar drops below the Minimum Set
Point. The Minimum Set Point and Temperature Differential can be set according to
instructions in the following Chapter. For example, if the Minimum Set Point is
14.4°C and the Temperature Differential is 2.2°C, the cooling unit will turn on when

11
the temperature inside the cellar rises above 16.6°C, and turn off when the
temperature falls below 14.4°C. In this example, the average temperature inside the
cellar will be 15.6°C.
1. Evaporator Air Intake. The evaporator coils are located on the face of the cooling
unit behind the grill. CellarPro cooling units are designed to be mounted at the
highest point inside wine cellars, so that warm air – which rises – will be the first to
pass over the evaporator coils, which will remove the heat from the air. To ensure
proper airflow, a minimum of 3”(76mm) clearance is required in front of the cooling
unit.
2. Evaporator Air Exhaust. Cold air is exhausted through the bottom of the cooling
unit. Because CellarPro cooling units are located at the highest point inside wine
cellars, the cold air will fall to the bottom of the cellar. To ensure proper airflow and
reduce temperature stratification inside the cellar, the space below the cold air
discharge should be clear of any obstructions, including wine bottles, wine racks, etc.
Power Requirements
CellarPro 1800XT 220V cooling systems should be plugged into an outlet connected
to a 15-amp circuit. These cooling units can be used in 187-254V single-phase
environments at 50Hz, and 198-254V single-phase environments at 60Hz. The
cooling unit uses approximately 2.0 amps during its “on” cycle. The power plug
provided is Nema 6-15P 15A 250V Plug (Male), with a screw cover plug housing and
internal lug connections that can be swapped to conform to local plug configurations.
A number of variables, including the minimum set point, the temperature in the
ambient environment, the insulation of the cellar, and the thermal mass inside the
cellar, will affect the cooling unit’s runtime. It is normal for the cooling unit to run up
to 75 percent of the time in order to maintain proper conditions inside the cellar.
Summary
Consider the following guidelines before purchasing a CellarPro wine cooling unit:
If the cellar is too large for the cooling unit, the cooling unit will be unable to
maintain proper, even temperatures throughout the cellar.
Without proper insulation and an airtight environment, the cooling unit effectively
will become a de-humidifier and potentially will produce buckets of water.
Without access to cool air, either because of improper ventilation or
environments that are too hot, the cooling unit will be unable to maintain proper
temperatures inside the cellar.
Under these conditions, the unit’s internal components may become damaged, the
expected useful life of the wine cooling unit may be adversely affected, and the
product’s warranty may become null and void.

III. Operating Instructions
Overview
Please follow the instructions in Chapter I prior to turning on your CellarPro cooling
unit.
CellarPro cooling units are designed to maintain optimal conditions for wine storage
and aging. These conditions include steady, cool temperatures, high humidity,
minimal vibration and light, and clean air.
The settings on your CellarPro cooling unit have been preset and optimized by the
factory. Before changing any settings below, we recommend waiting 14 days to allow
the cooling unit to “break in.”
The cooling unit is designed to cool the cellar gently without stripping moisture out of
the cellar environment. Therefore, it is not uncommon for the cooling unit to run
nonstop for up to a week initially, depending on the temperature inside the cellar, the
size of the cellar, and the temperature of the ambient environment. Once the cellar
has reached equilibrium, it is normal for the cooling unit to run as much as 75
percent of the time.
CellarPro cooling units are designed to maintain optimal temperatures for storing and
aging fine wine. CellarPro cooling units are not designed to maintain temperatures
for serving wine, which tend to be much colder than storage temperatures, especially
serving temperatures for white and sparkling wines.
CellarPro cooling units must be used, stored, moved and/or shipped in the upright
position. Be careful when turning the unit on its side. The unit NEVER should be
turned upside down.

13
Basic Operation
The temperature inside the cellar can be increased or decreased by changing the
Minimum Set Point as described later in this chapter. If the cooling unit runs too
much, you can raise the Minimum Set Point to reduce the cycle “on” time. Most wine
collectors store their wine in the range of 12.8 - 15.6°C.
CellarPro cooling units are designed to maintain appropriate levels of humidity,
ranging from 50 to 70 percent, inside wine cellars. In order to increase or decrease
humidity inside the cellar, the Fon setting can be changed as described in the
“Advanced Operation” section later in this chapter.

“warm” bottles in a cellar

16
Advanced Operation
CellarPro cooling systems can be programmed with advanced settings to achieve
more control over conditions inside the cellar. Conditions like humidity, the
Temperature Differential, and alarm settings all can be modified for custom
applications. To access the advanced settings, do the following:
Press the “Set” button and the “Down” button together at the same time, and
hold for three seconds. Then, use the “Up” or “Down” button to scroll to the
following screen:
HUMIDITY: The factory preset for this setting is “3”.
If the humidity inside the cellar is too low, press the “Set”
button, then use the “Up” button until the desired setting is
reached. The recommended range for this setting is 0-6.
TEMPERATURE DIFFERENTIAL: The factory preset for this
setting is “2.2”.
This setting determines the Temperature Differential and
therefore the temperature at which the cooling unit will cycle
on. The recommended range for this setting is 2.2 or 2.8.
HIGH TEMPERATURE ALARM: The factory preset for this
setting is “21.1”.
This setting designates the High temperature inside the
cellar at which the alarm is triggered. We recommend
leaving this setting at the factory preset.
LOW TEMPERATURE ALARM: The factory preset for this
setting is “7.2”.
This setting designates the Low temperature inside the cellar
at which the alarm is triggered. We recommend leaving this
setting at the factory preset.
ENERGY SAVINGS MODE DIFFERENTIAL: The factory
preset for this setting is “2.2”.
This setting increases or decreases the Temperature
Differential for the Energy Savings Mode. The
recommended range for this setting is 1.1-2.2.

17
Standard Protection Mechanisms
The cooling unit is programmed to shut down certain components to protect those
components, as well as the wine inside the cellar, under the following circumstances:
Scenario What it means What happens
P1 Alarm Probe 1, which senses
the temperature inside
the cellar and controls
the on/off cycles of the
cooling unit, has failed
The cooling unit enters a timed
auto-cycle mode until Probe 1 is
repaired or replaced. In this mode,
the cooling unit will turn for 12
minutes and off for 8 minutes.
Optional Protection Mechanisms
CellarPro cooling systems can be programmed to turn off the compressor and
condenser fan in the event of an HA2 alarm, as described below. If you’d like to turn
on this protection mechanism, please call us toll-free at 877.726.8496
P3 > 60°C for more
than 2 hours
The condenser probe
is measuring
temperatures that are
too hot
The compressor and condenser
fan will turn off until the condenser
temperature falls below 60°C
Maintenance
The condenser coils at the back of the cooling unit will collect dust, dirt and lint over
time. It is critically important to clean the coils periodically. If the condenser coils
become clogged, the cooling unit will not have
proper airflow and its performance and longevity
will be compromised.
To clean the coils, simply vacuum or brush the
coils until all dust and lint have been removed. Do
not use compressed air to clean the coils because
it may force dirt particles into the cooling system
and cause serious damage to its internal
components.

18
Alarms
The cooling unit has both an audible notification and a visual alarm indicator (shown
in “red” on the control panel) that are activated when an alarm is triggered. Please
note: the temperature alarms (HA, HA2, LA and LA2) are disabled during the first 23
hours of operation after the cooling unit is plugged in and/or turned on.
The control panel also will flash a code for each alarm, as follows:
Alarm Code What it means
What to do
P1, P2, P3 Probe Failure Call CellarPro at 877.726.8496

“PR2” flashes on the display
3. Using the “Down” button, scroll
until the display reads “AL2”
4. Depress the “Set” button and
lower the alarm temperature
setting to your desired setting

19
IV. Troubleshooting
The Cooling Unit Runs Constantly
The cooling capacity of the cooling unit depends on the thermal load on the wine
cellar, and the resulting BTU that is required to cool and maintain the cellar at the
desired temperature. The cooling capacities of both units are shown on page 2. If the
thermal load exceeds the capacity of the cooling unit, you will need to add insulation
and/or raise the set point on the cooling unit.
The cooling unit is designed to turn on when the air temperature in the cellar rises
ABOVE the Minimum Set Point + Temperature Differential, and turn off when the air
temperature falls below the Minimum Set Point. For example, if the Minimum Set
Point is 14.4°C and the Temperature Differential is 2.2°C, the cooling unit will turn
on above 16.6°C and turn off below 14.4°C. In this example, the average
temperature inside the cellar will be 15.6°C.
When bottles are first loaded in the cellar, the cooling unit will run continuously (even
up to a week) until the temperature inside the cellar falls below the Set Point. After
the temperatures inside the wine cellar reach equilibrium, the cooling unit will run
anywhere from 30 to 50 minutes in a given hour, depending on the thermal load and
the set point.
Hot weather conditions, insufficient insulation, inadequate ventilation, mis-sized
cellar capacity and/or dirty condenser coils can all cause the cooling unit to run
continuously.
If your CellarPro wine cooling unit runs constantly, try the following:
Make sure that both fans are spinning
Clean the condenser coils
Make sure that the cooling unit is NOT in Energy-Saver Mode
Check that the thermal load in Chapter II isn’t overwhelming the cooling unit
Increase the supply of cool air to the space outside the condenser coils, using
a fan, ducting or an exhaust system to remove heat from the space.
Raise the Minimum Set Point on the cooling unit
