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.

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. CellarPro Evaporators cold air exhaust and return can be ducted with a
hood up to 50 equivalent feet with 8” diameter ducting, or 100 equivalent feet with our auxiliary fan and 8” diameter ducting. We offer a duct kit (sold separately) with two fitting that attach to the front of the cooling unit and can be ducted.
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 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.
The unit is designed to operate in temperatures ranging from 0°F to 110°F.
Please note: An optional compressor heater is required for temperatures
below 40°F.
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
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.

Installing Refrigeration Lines
The Evaporator and Condensing units should be piped according to the following piping schematic:
Piping Legend
1. The 3/8"ODS liquid service valve is located on the Condensing unit.
2. Hermetic liquid line filter drier (shipped loose). Install with the directional flow arrow as shown.
3. Liquid line sight glass with moisture indicator (shipped loose).
4. Liquid line refrigeration piping in accordance with Line Sizing Chart.
5. Factory installed liquid line solenoid valve (normally closed) (Dual Power/Valve Control configurations only).
6. Factory installed thermostatic expansion valve. Bulb must be attached to a horizontal run of the suction line after brazing the field suction connection, and insulated with the supplied cork tape.
7. Factory installed suction service valve to use for setting expansion valve superheat.
8. Insulated suction line refrigeration piping in accordance with Line Sizing Chart.
9. 5/8"ODS suction service valve located on Condensing unit.
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.

4) Install refrigeration piping in accordance with local codes and ASHRAE guidelines.
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
19
Page 20
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.
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).

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 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.
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.

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. When the cooling unit is exposed to temperatures below 0°F, the cooling unit will be unable to maintain proper, even temperatures inside the cellar.
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 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
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 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.
24
Page 25
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.
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 2 degrees as shown in the “Advanced Operation” instructions below.

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.

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 Code What it means What to do
:
P1
