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



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



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



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



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.

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

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.

3) Use only dehydrated refrigeration service tubing and refrigeration grade fittings.

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



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).

20



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





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.

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 “0”.

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.

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:
