 Test the unit BEFORE installing it.
1. Let the unit sit upright for 24 hours before turning it on
2. Remove the unit from the box, and remove any materials that have been
packed inside the exhaust cavity. SAVE THE BOX AND PACKING MATERIALS.
3. Turn on the unit. PLEASE NOTE: This cooling unit is programmed with a 3-minute
delay at startup to protect its internal components.
4. Let the unit run on a hard, flat surface for no more than 10 minutes.
o Check for any alarms on the display
o Make sure that all fans are spinning.
o Check the cold air discharge from the bottom of the cooling unit - it
should be 8-10°F colder than the readout 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:
o TOP 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
shown in the Picture A). In this
configuration, the cavity on TOP
of the cooling unit is OPEN.
o REAR VENT CONFIGURATION: If the
hot air will be discharged through the REAR
of the cellar, use the exhaust panel to seal
the TOP of the cooling unit (as shown in the
Picture B). In this configuration, the cavity at
the REAR of the CellarPro is OPEN.

 CellarPro Cooling Capacity*
Each of our cooling units includes sizing guidelines that are based on R19 insulation
throughout the cellar and 85F peak ambient temperatures outside the cellar.*
To find the BTUH output for each of our 1800 cooling units at 55F and 60F, and the
thermal loads for various-size cellars, refer to the table below. In order to maintain your
desired cellar temperature, the cooling unit’s BTUH output (at 55F or 60F inside the cellar)
must be greater than the load of your cellar, as shown in the body of the table.
*If your cellar is constructed with glass, or has uninsulated walls, or does not have a vapor
barrier), the thermal load will be much higher than what’s shown in the table. In this
case, please .visit http://www.cellarprocoolingsystems.com/request-thermal-load to

 Ambient Environment
CellarPro interior cooling units are designed to operate in ambient temperatures
between 45°F and 95°F, and the exterior-rated 1800XTSx is designed to operate in
ambient temperatures between 20°F and 90°F.. Except for the 1800XTSx-EC cooling
unit, all cooling units are designed for internal use only, and are not designed for
exposure to the exterior.
CellarPro cooling units are not designed to generate heat inside the cellar, so if
temperatures inside the cellar drop below proper wine storage temperatures, the
cooling unit cannot increase the temperature 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.

7 v3.21
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. Please note: The R-values above are the MINIMUM recommended amounts of
insulation. It is advisable to use as much insulation as possible inside your walls,
ceiling and floor. All walls, joints, doors and windows, electrical outlets and/or
switches, pipes, vents and light fixtures should be sealed to prevent ambient air and
moisture from infiltrating into the cellar.
If the cellar is not well sealed, 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.
We offer 2 Condensate Drain Line options for
cooling units that will be installed in wine cellars
(as opposed to wine cabinets.) The REAR drain
line configuration includes a fitting and
condensate tube at the rear of the cooling unit
for excess condensate to flow from the rear of
the unit outside the cellar. The BOTTOM drain
line configuration includes a custom hole, a
barbed fitting and a condensate tube at the
bottom of the cooling unit for excess condensate
to flow from the bottom of the unit inside the cellar.
Our REAR drain line comes with the fitting installed in the rear of the cooling unit. Our
BOTTOM drain line requires installation of the fitting. To install, apply pipe joint sealant
(included) to the male threads of the barbed fitting, then hand-tighten the fitting into
the threaded drain line hole. Do not force – if cross threaded, back out and realign.
Finish by tightening the fitting with a wrench.

8 v3.21
Drain lines are recommended for installations in warm and/or humid environments;
however, the drain line does not replace the requirement for a cellar to be properly
constructed with proper insulation, moisture barrier and airtight seals.
When using a drain line, you must create a condensate trap as follows:
As shown above, the drain line should drop, then rise (but stay below the height of the
fitting), and then drop again, and must terminate in air, not liquid After installing the
trap, it must be charged with water as shown.
If your unit generates excess condensate and you don’t have a drain line, or you have
a drain line but no trap, the condensate may leak out of the front or bottom of the
cooling unit, and cause damage inside your walls or your cellar.

9 v3.21
I I I . I n s t a l l a t i o n I n s t r u c t i o n s – W i n e C e l l a r s
CellarPro cooling units are designed to be installed THROUGH THE WALL, with ample
open space on the sides and rear of the cooling unit. A hole should be cut 1/4 inch
larger than the dimensions (W x H) of the cooling unit. Horizontal 2 x 4 inch 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 tilted
slightly to the rear so that excess condensate flows to the rear of the cooling unit.
Inside the cellar, the front of the cooling unit catches warm air as it rises, pulls the air
across 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. A minimum of 8” of the front of the cooling unit must be protruding
inside the cellar, so that airflow (intake and exhaust) can occur as designed, unless
the unit is installed directly above the cellar and is installed together with our front
intake hood.
The front of the cooling unit requires a minimum of 3 inches of clearance inside the
cellar, and the bottom of the cooling unit requires clearance of 8 inches below the cold
air discharge.
Outside the cellar, the rear of the cooling unit should be flush with the outside wall –
ie the cooling unit should not be recessed in the wall unless the unit is installed with
our duct kit. The rear of the cooling unit must be installed in an open space that is at
least as large as the wine cellar (unless the rear intake and exhaust are ducted). Do
not install the unit in a corner, because ample space is required to the sides and rear
of the cooling unit in order for the unit’s hot air exhaust to dissipate without being
recycled into its fresh-air intake.

10 v3.21
The front of the cooling unit can be mounted using optional mounting clips (available
for purchase from CellarPro), as follows:
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” 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:

11 v3.21
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 is pliable, and is designed to be rolled and
stretched in your hands to fit around the entire cooling unit. (If you adhere the tape
before rolling and stretching it, you will not have enough tape to complete the job). 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).
 Ventilation
WITHOUT DUCTING
Proper ventilation is critically important for the proper operation of your CellarPro
cooling unit. The CellarPro cooling unit blows a significant amount of hot air through
the top or the rear of the cooling unit, and the hot air must be exhausted into a space
that is at least as large as the wine cellar in order for the heat to properly dissipate. If
the space is too small or constrained, eg because there’s a wall or obstruction to one
of the sides of the cooling unit, or there’s an obstruction directly behind the cooling
unit, the hot exhaust will not properly dissipate and the cooling unit will be forced to
recirculate its own hot air, which will impair its ability operate.

12 v3.21
1. Condenser Air Intake (Rear). 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. 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. Minimum clearance of 8 inches is required behind the cooling unit.
2. Condenser Air Exhaust (Rear or Top). 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.
 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 300 cubic feet, the exhaust
space also should be 300 cubic feet.) In addition, this configuration requires
sufficient clearance behind and to the sides of the rear of the cooling unit.
 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 300 cubic feet, the exhaust space also should be
300 cubic feet.).
WITH DUCTING
We offer a duct options that are designed to duct the HOT air exhaust and fresh air
return on indoor CellarPro 1800 cooling units, including:
 A duct hood that fits over the rear of the cooling unit and is designed to connect
to two 6” ducts (one for intake and one for exhaust), with a removable slot for
changing air filters;
 A 6” inline fan, plus wiring from the cooling unit that provides switched power
to the fan (the cooling unit cannot be ducted without an inline fan). When
connecting the fan to our switched power line, please follow local building
codes, which may require the use of conduit for the wiring and junction boxes
for any wire connections. The fan always should be installed on the exhaust
side of the ducting, in the same direction as the airflow (ie away from the cooling
unit).
 50’ (2 x 25’) of insulated 6” ducting (included with duct kits, but not duct
hoods).

13 v3.21
With our duct option, the hot side of our units can be ducted up to 50 equivalent feet
per duct. When calculating equivalent feet, each 90 degree turn in the ducting
approximately equals 8’ of ducting. Be sure to use gradual turns to avoid restricting
airflow inside the ducting. Consult your HVAC professional for further information.
IF THE COOLING UNIT WILL BE LOCATED ENTIRELY INSIDE THE CELLAR:
 The HOT side airflows (both exhaust AND intake) MUST be vented to space
outside the cellar with insulated ducting (R-6 minimum)
 The rear duct hood must be wrapped with insulation to minimize heat gain
inside the cellar
 The openings at the bottom of the rear duct hood must be sealed to prevent air
exchange inside the cellar
The COLD sides (ie Front) of 1800 cooling units cannot be ducted unless they are
located directly above the cellar. In this scenario, our front intake hood is required, and
2 openings will be required in the ceiling – one for the cold-air discharge, and one for
the return air from the cellar.
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 58°F
and the Temperature Differential is 4°F, the cooling unit will turn on when the
temperature inside the cellar rises above 62°F, and turn off when the temperature
falls below 58°F. In this example, the cellar temperature will average 60°F.
At least 8” of the front of the cooling unit must protrude inside the cellar – in other
words, the front of the cooling unit cannot be buried inside the wall.
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” of 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.

14 v3.21
 Power Requirement
CellarPro 1800 cooling systems require a dedicated 15-amp circuit. We recommend
using a surge protector to protect the internal components in case of a power surge.
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.
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
Keep in mind the following guidelines before purchasing a wine cooling unit from
CellarPro:
 If the cellar it too large for the cooling unit, and/or if the cellar does not have
adequate insulation, the cooling unit will be unable to maintain proper
temperatures throughout the cellar.
 Without a moisture barrier and an airtight environment inside the cellar, the cooling
unit effectively will become a de-humidifier and may produce buckets of water.
 The rear (hot side) of the cooling unit must be installed in a space OUTSIDE the
cellar that is at least as large as the wine cellar unless the rear intake and exhaust
are ducted.
 Unless ducted, both the front and the rear of the cooling unit require a minimum
clearance of 8 inches for the exhaust.
 The rear (hot side) of the cooling unit needs to have access to fresh, cool air to
operate properly. Without access to fresh, cool air, either because of improper
ventilation, installation in a small or restricted space, or environments that are too
hot, the cooling unit will be unable to maintain proper temperatures inside the
cellar and the HA2 alarm will be triggered.
 If the rear (hot side) of the cooling unit will be pulling air below 40F, the unit MUST
be equipped with a compressor heater.
 CellarPro 1800 cooling units require a dedicated 15-amp circuit

5. Open cabinet door and remove all bottles from the top of the rack.
6. Place a heavy towel or blanket on top of the wine rack for protection.
7. IF YOU HAVE A LE CACHE MODEL 2400 WITH A CENTER POST: Remove the
center post by unscrewing the screws (two at the top and two at the bottom)
that attach the post to the wine cabinet.
8. Unplug the light from the cooling unit inside the cellar, and also unplug the cord
from the light fixture.
9. Remove the light fixture as follows:
- Slide the light left or right, and then unscrew and remove one of the two
mounting brackets that attach the light fixture to the ceiling of the cellar.
- Slide the light fixture off the second mounting bracket.

16 v3.21
10. With 7/16 socket wrench, remove the two hex head bolts that attach the
cooling unit to the ceiling of the cellar. Save these bolts! Leave mounting
brackets attached to the cooling unit so that the proper location can be
duplicated with the replacement cooling unit.
PLEASE NOTE: If the nut in the ceiling becomes loose, you will need to use pliers
from the top of the cabinet to hold the nut and keep it from spinning with the
bolt.
11. The cooling unit is now free to remove. Drop front end down, and move side to
side to free from cabinet opening.
CAUTION: Two people may be required to remove the cooling unit, which weighs 58
pounds. Do not let the cooling unit drop on unprotected bottle racks.
TO INSTALL THE REPLACEMENT COOLING UNIT
1. Carefully remove the replacement cooling unit from the packaging. NEVER store the
cooling unit upside down or on its side, and NEVER turn the unit upside down. You
may reuse this packaging for shipping or storing the old cooling unit
2. Remove any materials that have been packed inside the exhaust cavity.
3. Before installing the cooling unit, make sure it works by plugging it in and letting
it run on a hard, flat surface for no more than 5 minutes. Check that cold air is
being produced by the unit. PLEASE NOTE: CellarPro cooling systems are
programmed with a 3-minute delay at start-up to protect its internal
components.
4. For top-vent configurations, make sure that the exhaust panel is installed at the
REAR of the cooling unit, so that the top of the unit has an opening for the hot
air exhaust. For rear-vent configurations, make sure that the exhaust panel is
installed in the TOP of the cooling unit, so that the rear of the unit has an
opening for the hot air exhaust. In both configurations, return air from outside
the cellar will come into the coils at the rear of the cooling unit.
5. If using mounting clips, attach the clips to the FRONT of the cooling unit so that the
short side slides under the metal fold near the top of the cooling unit, and space
the clips so that they’ll line up with the holes in the ceiling of the cellar. You may
need to remove the front grill (attached with two screws on each side of the cooling
unit) in order to slide the mounting clips under the sheet metal, then replace the
front grill after the clips are in place.
6. If your wine cabinet has three pieces of foam located on the bottom and on each
side of the black metal bracket that supports the rear of the cooling unit (attached
to the rear wall in most top-vented units), place these foam pieces along the bottom
and sides of the metal bracket.

17 v3.21
7. Install the cooling unit by following the removal instructions described above in
reverse.
8. A complete and proper seal must be made between the cellar and the cooling unit
to ensure that outside air does not enter the cellar. Use butyl adhesive tape to seal
the perimeter where the cooling unit touches the cellar by rolling the tape with your
fingers into a thin (pencil diameter) "rope", then press the tape into the cracks where
the cooling unit touches the cellar.
9. Check the seal by having a helper stand in front of the cabinet while you shine a
flashlight around the cooling unit edges to discover any gaps in sealant.
10. Wait 24-hours before running the cooling unit. We recommend plugging the cooling
unit into an outlet with a dedicated 15-amp circuit and a surge protector.
RETURNING THE ORIGINAL COOLING UNIT:
If the original cooling unit is under warranty and you are returning it, please follow the
instructions below:
1. Use the original packaging to repack the cooling unit.
2. Make sure that the cooling unit is upright in the box
3. The exterior of the box should be prominently marked with “This Side Up” and
“Fragile” for the freight carrier

V . O p e r a t i n g I n s t r u c t i o n s
Overview
Please follow the instructions in Section 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.
Remote Thermostat
Our remote thermostat will override the cooling unit’s internal thermostat, and can be
used to measure air or liquid temperatures inside the wine cellar. If measuring air,
place the thermostat in the cellar in a location with good airflow. If measuring liquid, fill
a bottle with mixture of water (80-90%) and rubbing alcohol (10-20%), insert the probe
into the bottle and use the rubber stopper on the thermostat to seal the bottle, and place
the bottle inside the cellar in a location with good airflow. If the bottle probe is used to
measure air temperatures, the differential (HY) on the cooling unit should be set to “4”.
If the bottle probe is used to measure liquid temperature, the differential should be set
to “1”. Refer to our “Advanced Operation” instructions for further instructions how to
change the HY differential.

19 v3.21
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 55 - 60°F.
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.
Digital Display
The temperature displayed on the control indicates the
real-time air temperature as measured by Probe 1 (P1)
located behind the front grill of the cooling unit, or the
temperature (air or liquid) being measured by the remote
thermostat (which overrides the internal probe).
