Important Notes
•Before plugging in and operating your CellarPro cooling unit, remove any
materials that have been packed inside the exhaust cavity.
•Wait 24 hours before plugging in and operating your CellarPro cooling unit.
•Before installing the cooling unit, make sure it works by plugging it in and letting it
run on a hard, flat surface. Check that cold air is being produced by the unit.
•NEVER turn the cooling unit on its side or upside down
•The cooling unit should be plugged into an outlet connected to a 15-amp circuit
•Before installing the cooling unit, make sure that the exhaust panel is installed in
the correct position – it MUST cover
either the TOP or the REAR exhaust
vent:
oTOP VENT CONFIGURATION::

Overview
CellarPro cooling units are engineered to maintain optimal wine storage conditions
inside wine cellars.
•Temperature
Proper temperatures are maintained by transferring heat from inside wine cellars
and exhausting the heat through the top (top-vent) or rear (rear-vent) of the cooling
units.
CellarPro cooling units are designed to turn on when the temperature 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. For
example, if the Minimum Set Point is 55°F and the Temperature Differential is 4°F,
the cooling unit will turn on when the temperature inside the cellar rises above 59°F,
and turn off when the temperature falls below 55°F.
A number of variables, including the temperatures of the ambient environment, the
insulation of the cellar and the thermal mass inside the cellar, will affect the speed
with which the temperature inside the cellar rises during the cooling unit’s “off” cycle.
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.
CellarPro cooling units are designed to cool up to 30°F below the ambient
temperature in the space outside the condenser coils.
•Humidity
Relative humidity is maintained by gently
cooling the cellar without removing
moisture from the environment.
Although the relative humidity in the
ambient environment will affect the level
of humidity inside the cellar, CellarPro
cooling units can be adjusted to increase
the level of relative humidity inside a
cellar,. The Fon setting (shown at right)
controls the amount of moisture
circulated inside the cellar. To increase
humidity inside the cellar, change the Fon setting per the instructions in Chapter III.

5
•Installation
CellarPro cooling units are designed to be installed inside the wine cellar, ideally
mounted to the ceiling of the cellar.
As warm air rises to the top of the cellar, it is pulled through the cooling unit where
the evaporator coils remove the heat from the warm air. Once cooled, the cold air is
discharged from the bottom of the cooling unit.
CellarPro cooling units should be mounted to the ceiling inside the cellar, or as close
to the top of the cellar as possible. Optional mounting clips for attaching the front of
the cooling unit to the ceiling are available for purchase from CellarPro. At a
minimum, the front 7” of the cooling unit must be inside the cellar, because the cold
air discharge is located underneath the cooling unit.
Once the cooling unit is installed, seal all the cracks and gaps between the cooling
unit and the cellar using the butyl tape provided in the cavity of the exhaust vent.
The butyl tape is 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).
CellarPro cooling systems should be plugged into an outlet connected to a 15-amp
circuit. The cooling unit uses approximately 3 amps during its “on” cycle. The cooling
unit also offers a grounded 115V AC outlet, which is rated for 3 amps.
We recommend plugging your CellarPro cooling unit into a surge protector (minimum
of 15-amps) to protect the electrical components from power surges or spikes. If
using an extension cord, use a grounded 14-gauge or heavier cord, and keep the
length to a minimum to avoid voltage drop.
•Ventilation
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.
CellarPro cooling 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.
•Top-vent configuration: 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.

6
-If the cellar’s air intake comes from BEHIND the cellar, the cooling unit
will require 3-4” of unobstructed clearance behind the cellar; and 8-9”
of clearance above the cellar;
-If the cellar’s air intake comes from the TOP of the cellar, the cooling
unit will require 18” of unobstructed clearance above and to both sides
of the cellar, unless:
1. The hot air exhaust is ducted away from the cellar; or
2. The hot air exhaust is evacuated via an exhaust fan.
•Rear vent configuration: 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. This configuration requires 3-4” of unobstructed
clearance behind the cellar.
Under both configurations, access to the intake coils (either at the top or the back of
the cellar) is required for periodic maintenance.
It is critical to follow guidelines for recommended clearance so that the hot air
exhaust is properly dissipated, otherwise the hot air will become trapped and the
cooling unit will circulate its hot air exhaust, thereby compromising the cooling unit’s
cooling capacity.
•Ambient Environment.
CellarPro cooling units are designed to operate in ambient temperatures between
50°F and 85°F.
CellarPro cooling units cannot maintain temperatures inside the cellar that are more
than 30°F below the ambient temperature in the space outside the condenser coils.
For example, if the ambient temperature in the space outside the condenser coils is
85°F, the cooling unit should be able to maintain temperatures of 55°F inside the
cellar.
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.
•Cellar Capacity
The cooling capacity for each of our products is shown in the table below. These
capacities are estimates and are based on certain assumptions, including sufficient

insulation, adequate clearance and airflow, and proper ambient temperatures in and
around the cellar.

Advanced Settings
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, press the “Set” button and “Down” button together
for three seconds.
This setting determines the Temperature Differential when
the cooling unit cycles on. The factory preset for this setting
is “4”.
The recommended range for this setting is 4-5, which will
allow the cooling unit to cycle “on” and “off”, will maintain
consistent air temperatures throughout the cellar, and
results in liquid temperature swings of approximately 0.5°F
This setting increases or decreases the humidity inside the
cellar. The factory preset for this setting is “0”.
The recommended range for this setting is 0-6. If the
humidity inside the cellar is too low at a setting of “0”, this
setting should be increased in increments of 1-2 units until
the desired humidity inside the cellar is achieved.
This setting designates the High temperature inside the
cellar at which the alarm is triggered. The factory preset for
this setting is “70”.
We recommend leaving this setting at the factory preset.
This setting designates the Low temperature inside the
cellar at which the alarm is triggered. The factory preset for
this setting is “45”.
We recommend leaving this setting at the factory preset.
This setting increases or decreases the Temperature
Differential for the Energy Savings Mode. The factory preset
for this setting is “4”.
The recommended range for this setting is 2-4.
