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.
We strongly recommend that the overflow drain line (shipped loose with the cooling
unit) be connected to the overflow drain (as shown in the installation section). In
addition, we recommend turning on the electric heating element to burn off excess
condensate that accumulates in the stainless steel pan during the initial cooling of
the cellar and during high run-times, as well as in high-humidity environments.
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
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. Cold air exhaust and return (from the evaporator) can be ducted with
our front duct hood up to 50 equivalent feet using 8” diameter insulated ducting,
or 100 equivalent feet with an auxiliary inline fan. 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
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
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
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 a drain or bucket. 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.

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.

3) Use only dehydrated refrigeration service tubing and refrigeration grade fittings.
4) Install refrigeration piping in accordance with local codes and ASHRAE guidelines.
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:
20
Page 21
1. When the evaporator and condensing unit are located on the same level,
arrange the suction line slightly downward to the condensing unit, as
follows:
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, the suction
line must be laid out with double arcs in the form of oil traps above and below.
This is done using a U-shaped arc at the lower end and a P-shaped arc at the
upper end of the vertical riser, as follows:
21
Page 22
Evacuation, Leak Detection, and Charging
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 service valves open to atmosphere
for more than 15 minutes.
2. Open the liquid and suction service valves on the condensing unit.
3. a. Dual Power Source / Valve Control: 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.
b. Not applicable
4. Pressurize the system to a maximum of 150PSIG of dry nitrogen. 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.
5. Evacuate the system to a minimum of 500 microns. If the vacuum is
achieved, proceed to the next step, otherwise locate and repair the leak and
repeat from step 4.
6. 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, as detailed in the next step. DO NOT USE
REFRIGERANT WITH ADDITIVES.
22
Page 23
7. Warm the bottom shell of the compressor above the ambient temperature for
30 minutes to drive excess refrigerant out of the compressor oil. Connect
power to the Evaporator and Condensing unit, and activate the system.
Check that the sight glass is clear when the compressor is running. The
condensing temperature must be above 105°F (135.0 PSIG) when inspecting
for a clear sight glass. In a low ambient environment, it may be necessary to
block off the condenser air intake to force the condensing temperature higher.
If the sight glass is not clear, slowly add vapor refrigerant though the suction
service valve.
8. With a clear sight glass, adjust the superheat on the thermostatic expansion
valve to 10°F +/- 2°F, as measured at the suction access valve located in the
Evaporator.
9. Once the superheat is adjusted, ensure the condenser face airflow is
unrestricted and allow the system to balance for 30 minutes.
10. Check the suction superheat at the compressor using the access port on the
suction service valve. A minimum superheat of 20°F is required at this
location. If it is below 20°F, recheck the thermostatic expansion valve
superheat and increase as necessary to ensure a 20°F superheat at the
compressor.
11. Adjust the fan cycling control (located on the Condensing unit) so that the
condenser fan cuts-out at approximately 90°F (104.5 PSIG), and cuts-in at
120°F (171.0 PSIG). Verify pressures with valve manifold gauges at startup.
23
Page 24
Installation Tips and Guidelines
When brazing copper tubing to the service valves, use 95/5 solder and
soldering flux. Do not use silver solder because it requires higher heat that
will damage the service valves.
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 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.
Continue charging until system has sufficient refrigerant for proper operation.
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.
Do not leave unit unattended until the system has reached normal operating
conditions.
Make sure all access valve caps are in place and tight.
Make sure liquid and suction service valves are properly back-seated and
tighten valve packing if necessary.
Make sure the condenser fan cuts-in at 171 PSIG and cuts-out at 104.5 PSIG.

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 beca u se t he 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.
26

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 posi tion. 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
Temperature Differential is 4
temperature rises above 62
°
F, the cooling unit will turn on when the
°
F inside the cellar, and it will turn off when the
F and 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
27
Page 28
humidity inside the cellar, the

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, exteme 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.

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 “4”.
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 4 or 5.
HIGH TEMPERATURE ALARM: The factory preset for this
setting is “70”.
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 “45”.
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 “4”.
This setting controls the Temperature Differential for the
Energy Savings Mode. The recommended range for this
setting is 2-4.

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. Check that the cellar has airtight seals, including the door(s), light fixtures, and all
walls, ceiling and floor.
3. 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.

Maintenance
The condenser coils on the Condensing unit will collect dust, dirt and lint over time. If
the condenser coils become clogged, the cooling unit will not have proper airflow
and its performance and longevity will be compromised. The condenser coils
themselves also can be cleaned with a vacuum cleaner – ideally with a brush
attachment to loosen dust caught between the fins.
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 and LA) 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 What it means What to do
P1 Probe 1, which senses the
temperature inside the cellar and
controls the on/off cycles of the
cooling unit, has failed
HA The temperature inside the cellar
is too warm (above 70°F for more
than 1 hour)
LA The temperature of the cellar is
too cold
(below 45°F)
HA2 The temperature of the condenser
is too high (above 140°F)
LA2 The ambient temperature at the
condenser coil is too cold
The cooling unit enters a timed autocycle mode until Probe 1 is repaired or
replaced. In this mode, the cooling unit
will turn on for 12 minutes and off for 8
minutes.
