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 important 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.
The drain line (shipped loose with the cooling unit) must be connected to the drain
pan (as shown in the installation section).
Fan Speeds
Your fan speed setting will depend on the thermal load on the wine cellar, and the
resulting BTU that is required to cool and maintain your wine cellar at the desired
temperature.
Ventilation
Adequate ventilation is critically important for the proper operation of your CellarPro
cooling unit.
8 V10.14
Page 9
Outside the Cellar
Condensing unit Air Exhaust. Condensing units create significant 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.
In this event, the cooling unit will be forced to re-circulate its hot air exhaust and/or
the static pressure will back up the cooling unit. If this happens, the cooling unit’s
ability to create cold air inside the cellar will be compromised.
Condenser Air Intake. The condenser coils require access to cool air in order for
the cooling unit to produce cold air. In addition, the cooling unit must be installed
so that, after its installation, the condenser coils are accessible for periodic cleaning.
The Condensing unit cannot be ducted.
Inside the Cellar
Evaporator Air Intake. When the warm air passes across the evaporator coils, heat
is removed from the air, and the resulting cold air is exhausted into the cellar. To
ensure proper airflow, minimum clearance of 12” is required in front of the cooling
unit.
Evaporator Air Exhaust. Cold air is exhausted at the top front of the cooling unit.
Because CellarPro cooling units are located at the highest point inside wine cellars,
the cold air exhaust eventually will drop to the bottom of the cellar. To ensure proper
airflow and reduce temperature stratification inside the cellar, the space in front of
the cold air discharge should be clear of any obstructions, including wine bottles, wine
racks, etc.
Ducting For the Evaporator (3000S/4000S Models). Cold air exhaust and return
(from the evaporator) can be ducted with our front duct hood up to 100 equivalent
feet of total ductwork, or 50 equivalent feet for both the discharge and return
ducting, using 8” diameter insulated ducting. Our front duct kit is compatible
exclusively with our 3000S and 4000S cooling units. If you’d like to duct one of our
larger cooling units, please consider our AH6500 and AH8500 cooling units.
Before attaching the front duct hoods, remove the front grill (if present) from the
front of cooling unit.
We also offer a remote control panel kit that can be installed remotely (up to 10 feet)
from the cooling unit, either inside or outside the cellar, and a bottle probe (10 foot
cord) that can be plugged into the cooling unit.

III. Installation Instructions
Installation Instructions
Split System piping and wiring must be installed by a qualified Refrigeration
Technician in accordance with local and national code requirements.
Condensing Unit Installation
Indoor and Outdoor Units
The unit is designed to operate in temperatures ranging from 0°F to 110°F. A
compressor heater (sold separately) is required for temperatures below 40°F.
Indoor Units
Condensing units can be installed remotely from the cellar in an area protected
from direct exposure to moisture and sunlight.
The area must have suitable ventilation to maintain an ambient temperature of
110°F or less.
If the area does not have adequate ventilation, a vent fan should be added to
supply fresh air to the space (suggested 600CFM).
A minimum of 12" of open air space is required in front of the condenser coils.
Indoor units can be installed with the optional outdoor hood if additional
mechanical protection is desired.
A minimum of 12" of open air space around the perimeter of the outdoor hood
is required.
Outdoor Units
Condensing units must be installed with the outdoor hood if the unit will be
located outdoors.
A minimum of 12" of open air space around the perimeter of the outdoor hood
is required.
Evaporator Unit Installation
As warm air rises to the top of the cellar, the cooling unit pulls the warm air through
the evaporator coil and removes the heat from the warm air. Once cooled, the cold
air is discharged from the front of the cooling unit and circulates through the cellar.
Therefore, we recommend mounting the evaporator as close to the ceiling as
possible inside the cellar.
10 V10.14
Page 11
3000S / 4000S
Side mounting brackets are provided for mounting the evaporator flush to a wall
inside the cellar. Optional top and bottom brackets (non-load bearing) are available
upon request.
11 V10.14
Page 12
3000Sh / 4000Sh / 6000S / 8000S
Wall hangers are used to mount these split systems. First, wall brackets are
attached to the wall, and then the evaporator slides onto the brackets. After the
evaporator is installed, two bottom nuts must be installed on the recessed anchor
studs.
12 V10.14
Page 13
Condensate Drain Line
The condensate drain line should drop, then rise (but stay below the height of the
fitting), and then drop again into an open drain. Then, fill the trap with water. The
condensate trap will allow any excess moisture inside the Evaporator to
overcome the static pressure and flow out of the drain line. Before putting the unit
into service, test for positive drainage by pouring water into the drain pan and
observing flow through to the final drain.

System Wiring – Option A: Dual Power / Valve Control
Under this configuration the Evaporator and Condensing units are separately
powered, and the Condensing unit turns on and off based on suction pressure, as
follows:
The Evaporator includes a factory installed liquid line solenoid valve (LLSV),
which is controlled by the Evaporator temperature controller. The Condensing
unit is controlled by a low pressure switch which reacts to the suction pressure
and senses whether the LLSV is open or closed.
When the Evaporator temperature set-point is reached and the Evaporator
turns off, the LLSV closes, causing the system to pump down until the low
pressure switch shuts off the Condensing unit.
When the Evaporator turns on, the LLSV opens, causing the suction
pressure to rise and activate the Condensing unit.
Field power wiring is connected to both the Evaporator and Condensing units, no
interconnecting wiring is needed between the Evaporator and Condensing unit.
Evaporator Field Power Wiring:
Connect line lead to Evaporator terminal "L"
Connect neutral lead to Evaporator terminal "N"
Connect power ground to grounding lug on Evaporator
Condensing Unit Field Power Wiring:
Connect line lead to Condensing unit terminal "L1"
Connect neutral lead to Condensing unit terminal "L2"
Connect power ground to grounding lug on Condensing unit.

2) Chart includes allowances for Fittings, Filter Drier, and Sight Glass.
Line Sizing Chart
Refer to the Line Sizing Chart below for selecting the appropriate tubing size for
the length of the piping run. Note that the recommended line size may not match
the connection ports on the Condensing unit and the Evaporator. Refrigeration
grade fittings must be supplied by the installing technician to make the necessary
transitions. Transitions should be made as close to the unit as possible.
Suction line routing must be designed to ensure oil return to the Condensing unit.
Vertical Piping Guidelines
Piping runs should be kept as short and compact as possible. Low-lying areas (oil
“traps”) where oil can accumulate should be avoided. Refer to the following
guidelines with regards to the vertical placement of the evaporator and condensing
units:
25 V10.14
Page 26
1. When the evaporator and condensing unit are located on the same level,
pipe suction line with inverted trap as shown to prevent liquid migration to the
compressor during the off cycle. Pitch the suction line slightly downward to
the condensing unit:
2. When the evaporator is located below the condensing unit, a suction trap
must be installed at the evaporator, and an inverted trap must be installed at
the condensing unit, for proper oil return, as follows:
3. When the evaporator is located above the condensing unit, pipe suction line
with inverted trap as shown to prevent liquid migration to the compressor during
the off cycle. The vertical lift of the liquid line is limited to 30 feet. The lift may be
increased to 60 feet if an optional liquid/suction Heat Exchanger is added to the
field piping.
26 V10.14
Page 27
Evacuation, Leak Detection, and Charging
Important note: The condensing unit and evaporator are shipped with a nitrogen
holding charge. Please verify positive pressure through the access valve prior to
installation. If you cannot verify the holding charge, please contact Cellarpro at
707.794.8000.
Once the piping is installed, the following steps should be performed to ensure a
dry and leak-free system:
1. The Condensing unit is pre-charged with compressor oil. To avoid moisture
contamination of the oil, do not leave the system open to atmosphere for more
than 15 minutes.
2. Dual Power Source / Valve Control Systems Only: Supply power to the
Evaporator only - DO NOT connect power to the Condensing unit. Turn on the
temperature controller, which will energize and open the liquid line solenoid
valve. Verify the solenoid is powered as indicated by the compressor icon
("snowflake") on the temperature controller display.
3. Pressurize the system to a maximum of 150PSIG of dry nitrogen. It is important
to add nitrogen though both the high and low side access valves on the
condensing unit to make sure the system is fully pressurized. Mark the
pressure and hold for a minimum of 1 hour. If the pressure holds, proceed to
the next step, otherwise locate and repair the leak and repeat this step.
4. Evacuate the system to a minimum of 500 microns. It is important to pull a
vacuum though both the high and low side access valves on the condensing
unit to make sure the system is fully evacuated. If the vacuum is achieved,
proceed to the next step, otherwise locate and repair the leak and repeat from
step 4.
27 V10.14
Page 28
5. Disconnect the vacuum pump, but leave the system under vacuum. Use a
charging scale to accurately weigh in the refrigerant. Charge liquid R-134a
refrigerant through the liquid service valve according to the charge pounds
indicated in the "System R-134a Charge Guidelines" chart below. Additional
refrigerant may need to be added, using the steps outlined below. DO NOT
USE REFRIGERANT WITH ADDITIVES.
6. Important: The most common causes of compressor failure are
refrigerant overcharge, adding liquid refrigerant through the suction
access valve, and cold compressor starts. If your system is equipped with
a compressor heater, make sure this is wired to be energized even when the
system is idle. If starting up the system in a cold ambient, or if the system has
been sitting idle without the compressor heater energized for more than 24
hours, it is critical to warm the bottom shell of the compressor above the
ambient temperature for 30 minutes to drive excess refrigerant out of the
compressor oil.
7. Connect power to the Evaporator and Condensing unit, and activate the
system. IMPORTANT: If the system does not power up after the 3 minute
start up delay, verify field wiring according to the appropriate wiring
diagram. If correct, disconnect power from the system and contact
Cellarpro at 707.794.8000.
Measure pressures and temperatures to verify the system is within normal
operating limits as indicated on the Split System Data Sheet. A loose copy of
the Data Sheet is provided with the unit, and an additional copy is included at
the end of this manual. The condensing pressure must be above 105 PSIG
when taking these measurements. In a low ambient environment, it may be
necessary to temporarily block off the condenser air intake to force the
condensing pressure higher. Do not run the system if the suction superheat at
the condensing unit is below 20°F.
8. It may be necessary to slightly adjust the charge amount after weighing in the
recommended initial charge. 1) Not enough refrigerant: If the Evaporator is not
providing enough cooling, the system may be undercharged. If liquid
subcooling is below 10°F and the suction superheat is well above the minimum
of 20°F, slowly add vapor refrigerant though the suction service valve until the
subcooling is within specifications. 2) Too much refrigerant: If the suction
superheat is below 20°F, remove refrigerant until the superheat is above this
minimum limit.
9. (Optional) It should not be necessary to manually adjust the thermostatic
expansion valve superheat from the factory default setting. However if desired,
the superheat may be adjusted as follows: 1) Remove the cork tape insulation
from the expansion valve body to locate the cap on the superheat stem, and
unscrew the cap using a 5/32 in. Allen wrench. 2) Using a 5/32 in. Allen wrench,
locate the setting spindle inside the superheat stem and make superheat
adjustments ¼ turn at a time (¼ turn≈1°F). Turning clockwise increases
superheat. Turning counter-clockwise decreases superheat. The target
superheat at the evaporator is 10°F +/- 2°F. 3) Reinstall the cap and cork tape
insulation.
28 V10.14
Page 29
10. Confirm that the compressor, condenser fan, and evaporator fan(s) are
energized. Allow the system to balance for 30 minutes, then record all readings
on the Data Sheet and submit to CellarPro for warranty activation review.
11. Observe that the condensing unit turns on when the “snowflake” icon on the
temperature display is lit solid (not blinking), and turns off when the “snowflake”
icon turns off. It may be necessary to temporarily raise the set point to force
the unit to cycle off. If the condensing unit does not cycle on/off in conjunction
with the “snowflake” icon, please contact the factory for assistance.
Installation Tips and Guidelines
Make sure all electrical connections are secure.
Inspect Evaporator and Condensing unit fans to confirm airflow. There shouldn’t
be any excessive vibration, noise or obstructions to airflow.
Observe system pressures and temperatures during charging and initial
operation and keep note of them as they will be required for the Service and
Support Data Sheet which initiates the warranty.
Do not overcharge or use refrigerant with additives.
Remember that bubbles in a sight glass may be caused by a restriction as well
as a shortage of refrigerant. A properly charged system may still have small
bubbles visible in the sight glass, so use actual superheat and subcooling
readings to charge the system.
Do not leave unit unattended until the system has reached normal operating
conditions, and the system has been observed properly cycling on/off to the
desired set point and differential.
Make sure all access valve caps are in place and tight.

foot cord) that can be plugged into the cooling unit.
Summary
Keep in mind the following guidelines before purchasing a wine cooling unit from
CellarPro:
If the cellar is too large for the cooling unit, the cooling unit will be unable to
maintain proper, even temperatures inside 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 because the environments is too hot, the cooling unit will be unable to
maintain proper temperatures inside the cellar.
When the cooling unit will be exposed to temperatures below 40°F, a
compressor heater must be added to protect the compressor.
Under any of the above 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.

IV. Operating Instructions
Overview
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.
Temperature Control
CellarPro cooling units are designed to turn “on” when the air temperature passing over
the evaporator coils inside the cellar exceeds the Minimum Set Point plus the
Temperature Differential, and turn “off” when the temperature drops below the
Minimum Set Point. 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 rises above 62°F inside the cellar, and it will turn off when the
temperature falls below 58°F. In this example, the average temperature inside the
cellar will be 60°F.
Basic Operation
The cooling system is programmed with a 3-Minute Delay at Startup to protect its
internal components. 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
32 V10.14

humidity inside the cellar, the
Fon
setting can be changed as described in the
“Advanced Operation” section later in this chapter.
Switch Instructions
(1) Control Panel: Maintains desired cellar environment. Factory settings are
optimized for peak performance. Controller is described in detail in the following
section.
(2) Fan Speed Selector Switch (Low/Med/High): The cooling unit fans operate on 3
speed settings: Low, Medium, and High. For optimum sound and energy efficiency,
select the lowest fan speed that will maintain the desired cellar temperature. High
speed is recommended for initial cellar pull down, extreme temperature conditions
and ducted installations.
(3) Bottle Probe Jack (Bottle Probe): Plug in the remote bottle probe (sold
separately) to control the cellar by liquid temperature rather than air temperature
inside the cellar. Disconnecting the probe will automatically return the control to air
temperature. When using a bottle probe, the Temperature Differential will need to
be adjusted to 1 as shown in the “Advanced Operation” instructions below.

V. Troubleshooting
Improper installation, inadequate insulation, or a cellar that is too large will
cause the cooling unit to run continuously and be difficult to troubleshoot.
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 58°F and the Temperature Differential is 4°F, the cooling unit will turn above 62°F
and turn off below 58° F. In this example, the average temperature inside the cellar will
be 60°F.
Cooling Unit Runs Constantly
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.
Hot weather conditions, insufficient ventilation and/or dirty condenser filters may cause
the cooling unit to run continuously. To reduce cycle times,
1. Remove any obstructions to air flow to or from the unit
2. Check to make sure the condenser filter is clean
3. 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.
4. Raise the Minimum Set Point on the cooling unit
Cooling Unit Is Dripping
The cooling unit is designed to remove excess moisture from inside the cellar, which
collects in the drip pan of the cooling unit and is evaporated by the condensate heater.
Excess moisture can occur when the cooling unit runs constantly, when the Minimum
Set Point is too low and/or when the cellar doesn’t have a good seal from the outside
environment. To eliminate overflow, do the following:
1. Ensure the condensate overflow drain line is not blocked, that the drain line is trapped
and the trap is filled with water.
2. Ensure there is a downward pitch in the drain line from the outlet at the unit drain pan
to the final drain. It may be necessary to install a trap vent as detailed in the
Condensate Drain Line installation section.
3. Check that the cellar has airtight seals, including the door(s), light fixtures, and all
walls, ceiling and floor.
4. Raise the Minimum Set Point of the cooling unit.
The Cooling Unit Won’t Turn On
The cooling system is programmed with a 3-Minute Delay at Startup to protect its
internal components.
