Cellar Construction
Insulation

CellarPro cooling units are designed to be installed inside wine cellars that have pro per
insulation, moisture barriers and an airtight seal from the environment outside the
cellar. Interior walls and floor
should have a minimum of R­11 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 weather­stripping 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 wall­joints, 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 condensate drain line and optional humidifier drain line must be connected to a
suitable drain.

Fan Speeds

Your evaporator module fan speed setting will depend on the amount of ducting and
thermal load on the wine cellar, and the r esulting airflow and BTUH that is required
to cool and maintain your wine cellar at the desired temperature. Your condensing
module fan speed setting will depend on the condenser air intake temperature and the
amount of ducting, allowing for sufficient airflow to reject the heat absorbed by the cooling
system.

Ventilation

Adequate ventilation is critically important for the proper operation of your
CellarPro cooling unit, particularly on the condenser (hot) side of the cooling unit.

7

Condenser Air Exhaust/Intake.

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, th e cooling unit’s
ability to create cold air inside the cellar will be compromised. In addition, the
cooling unit must be installed so that, after its installation, the condenser coils are
accessible for periodic cleaning.

Evaporator Air Exhaust/Intake.

When the warm air from the cellar passes across
the evaporator coils, heat is removed from the air, and the resulting cold air is
exhausted into the cellar. On non-ducted installations, a minimu m clea rance of 12” is
required from all air intake and discharge locations to maintain proper airflow. Cold
air exhaust must be 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.

Evaporator/Condensor Ducting.

CellarPro Air Handlers exhaust and return (hot
and cold side) can be ducted up to 50 equivalent feet (100' total equivalent feet
exhaust and return) with 10” diameter ducting. With our units we offer duct adaptors
and ducting that attach to either the evaporator or condenser module.

II. Installation Instructions

Configuration Options

The Air Handler comes in three basic configurations:

 Horizontal configuration - which can be installed inside or outside the cellar.

Additionally it can be installed through the wall with a portion of the unit in the cellar
and outside the cellar.

 Vertical configuration – this is the ‘stacked’ option which is a space saving approach.
 Split configuration – with the evaporator in the cellar (ductless) or outside (ducted)

and with the condenser either inside or outside the house or building.

Horizontal Configuration.
Through wall: The unit is installed through the cellar wall with the evaporator module
inside the cellar, and the condenser module outside. The unit requires a mounting shelf,
sized to fit the width and depth of the unit and strong enough to support the weight of the
unit. The unit is secured to the mounting shelf using (4) 1/4-20 bolts secured to captive
nuts located in the bottom corners of the unit (note: the provided leveling feet must be
removed). The condenser can be provided with grills to vent the air, or duct adapters to
duct the intake, discharge, or both. The condenser module can also pass through the
cellar wall to an outdoor exposure by installing optional outdoor louvers to the intake and
discharge air panel openings.

Remote ducted: The unit is mounted remote to the cellar, and the evaporator module
intake and discharge air are ducted to the cellar. The condenser can be provided with
grills to vent the air, or duct adapters to duct the intake, discharge, or both. The
condenser module can also pass through an exterior wall to an outdoor exposure by
installing optional outdoor louvers to the intake and discharge air panel openings. The
unit may be floor mounted on the leveling feet provided, or flush to the floor with the
leveling feel removed. The unit may be ceiling hung using six 1/4-20 threaded rods (field
provided), attaching to captive nuts provided in the top corners and middle edges of the
unit.

Inside cellar: The unit can be mounted inside the cellar, provided that the condenser
intake and discharge are ducted to a suitably ventilated area outside the cellar.

9

10

Vertical Configuration.
Through wall: Vertical units cannot be mounted in a through wall configuration.

Remote ducted: Vertical units can be mounted remotely with the evaporator intake and
discharge air are ducted to the cellar. The condenser can be configured with grills to
vent the air provided that the location is suitably ventilated, or with duct adapters for
ducting the intake, discharge, or both to a suitably ventilated area. The unit may be
floor mounted on the provided leveling feet, or flush to the floor with the leveling feel
removed. The unit cannot be ceiling hung, and cannot be installed outdoors.

Inside cellar: Vertical units can be located inside the cellar, with the condenser intake
and discharge ducted to a suitably ventilated area outside the cellar.

11

Split Configuration.

Models in the Split Configuration can be mounted as follows, with interconnecting wiring
and refrigerant piping field provided by an experienced Refrigeration contractor:

Remote ducted: The unit is mounted remote to the cellar, and the evaporator module
intake and discharge air are ducted to the cellar. The condenser can be provided with
grills to vent the air, or duct adapters to duct the intake, discharge, or both. The
condenser module can also be located outdoors by installing optional outdoor louvers to
the intake and discharge air panel openings. The separate modules may be floor
mounted on leveling feet, or flush to the floor with the leveling feel removed. Each
module may be ceiling hung using four 1/4-20 threaded rods per module (field
provided), attaching to captive nuts provided in the top corners of the module.

Inside cellar: The evaporator module can be mounted inside the cellar as follows:

 The module may be floor or shelf-mounted, or flush to the floor or shelf with the

leveling-feet removed. If shelf mounted, the evaporator module requires a
mounting shelf designed to support the weight of the module, and secured by
four 1/4-20 bolts secured to weld nuts located in the bottom corners.

 The module may be ceiling hung using f our 1/4-20 threaded rods (field provided),

attaching to captive nuts provided in the top corners of the module.

Condensing Units - Indoor

 Condensing units can be installed remotely from the cellar in an area protected

from direct exposure to moisture and sunlight.

 The area must have adequate ventilation to maintain a 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.

 On units that are not ducted, a minimum of 12" of open air space is required in

front of the intake and discharge air panels.

Condensing Units - Outdoor

 Both the Horizontal and Split configurations can be installed with the Condenser

module located outdoors, with optional outdoor louvers installed in the air intake
and discharge positions.

 The unit is designed to operate in temperatures ranging from 0°F to 110°F.

Please note: Our compressor heater (ordered separately) is required for
temperatures below 40° F.

 A minimum of 12" of open air space is required in front of the intake and

discharge air panels.

 Knockouts are provided in the unit housing for field connection of conduit. The

conduit must be liquid tight and approved for outdoor use. Conduit fittings shall
be in accordance with UL 514B.

Condensate Drain Line – description and layout

The Air Handler has been designed to minimize the amount of condensation created when
cooling. The condensate that does form on the evaporator will gather in a tray and be
channeled to the drain, through a small trap, and then out through the side of the unit where
it exits via a barbed fitting.

14

Power Supply Requirements

The Air Handler is a high performance cooling system and with significant power
requirements. Each of the two sections of the unit, evaporator and condenser, requires
its own power source or cord. The amps and watts for the configurations are listed

System Wiring - Self Contained Configuration / Cord Connected

Models in the Horizontal or Vertical configurations are provided with two power cords
for connection to two dedicated 115V/60HZ power receptacles. Each power
receptacle must be on a separate circuit breaker, sized by model and module
according to the electrical data table. Both power cords must be connected for the unit
to operate.

System Wiring - Split Configuration / Cord Connected (Electronic Control)

Models in the Split Cord Connected configuration are provided with two power cords
for connection to two dedicated 115V / 60HZ power receptacles. Each power
receptacle must be on a separate circuit breaker, sized by model and module
according to the electrical data table. Both power cords must be connected for the unit
to operate. Field power wiring is required to connect the evaporator module to the
condenser module as shown on diagram below this section. Marked field connection
terminal blocks are provided in each module for the interconnecting wiring. Wiring
should be 18AWG minimum, copper conductors only, enclosed in conduit in
accordance with code requirements for the installation.

System Wiring - Split Configuration / Permanently Connected (Valve Only)

Models in the Split Permanently Connected configuration must be field wired to two
dedicated 115V / 60HZ circuit breakers, sized by model and module according to the
electrical data table. Field power wiring for both the evaporator module and condenser
module is shown on the diagram below. Wiring must be sized to the load, copper
conductors only, and done in accordance with code requirements for the installation.

Under this configuration the Evaporator and Condenser modules are separately
powered, and the Condenser module turns on and off based on suction pressure, as
follows:

 The Evaporator module includes a factory installed liquid line solenoid valve

(LLSV), which is controlled by the Evaporator temperature controller. The
Condenser module 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 temperat ure set-point is reached and the Evaporator tu rns off,

the LLSV closes, causing the system to pump down until the low pressure switch
shuts off the Condenser module.

 When the Evaporator turns on, the LLSV opens, causing the suction pressure to

rise and activate the Condenser module.

Field power wiring is connected to both the Evaporator and Condenser module, no
interconnecting wiring is needed between the Evaporator and Condensing modules.

1. The 3/8"ODS liquid service valve located on Condenser Module.

2. Hermetic liquid line filter drier (shipped loose). Install with the directional flow arro w 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) (Valve Control
configurations only).

6. Factory installed thermostatic expansion valve.

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 Condenser Module.

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.

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.

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

4) Install refrigeration piping in accordance w i th local codes and ASHRAE guidelines.

Evacuation, Leak Detection, and Chargi ng

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 serv ice valves on the condensing unit.

3. Valve Control 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
po wer ed as ind ica ted by th e compressor icon ("snowflake") on the temperature
controller display.

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 t he vacu um is achieved,

proceed to the next step, otherwise locate and repair the leak and repeat from step 4.

20

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 R­134a Charge Guidelines" chart below. Additional refrigerant may need to be added,
as detailed in the next step. DO NOT USE REFRIGERANT WITH ADDITIVES.

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. The fan cycling control (optional) is located in the Condenser Module and is non­adjustable. The condenser fan cuts-out at approximately 75 PSIG, and cuts-in at
120PSIG. Verify condenser fan operation at startup.

21

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 se cure.
 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 init iates
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 proper ly back-seated and tighten

valve packing if necessary.

 Make sure the condenser fan cuts-in at 120 PSIG and cuts-out at 75 PSIG.

Summary

Keep in mind the following guidelines when selecting your 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 bucket s 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.

III. Operating Instructions

Overview

CellarPro cooling units are designed to maintain optimal conditions for wine storage an d
aging. These conditions include steady, cool temperatures, high humidity, minimal
vibration and light, and clean air. he 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 th e
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 s ize o f 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

aging

fine wine. CellarPro cooling units are not designed to maintain temperatures for

serving

temperatures for white and sparkling wines.

CellarPro cooling units must be used, stored, moved and/or shipped in the
upright position.

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

Temperature Differential,
Minimum Set Point

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
un it runs to o 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. CellarPr o cooling units
are designed to maintain appropriat e le vel s of hu mid ity , ranging from 50 to 70 percent,
inside wine cellars. In order to increase or decrease humidity inside the cellar, the
setting can be changed as described in t he “Advanced Operation” section later in this
chapter.

Humidifier (optional):

Recommended for installations where the ambient humidity is insufficient to maintain 50
to 70%RH inside the cellar. The humidity control is remote mounted with 10ft of
interconnecting wire inside the cellar. Refer to separate manual for detailed installation
and operating instructions for the humidifier and humidity controller.

Heating (optional):

The air handler can be configured with an electric air heater for installations where the
cellar may drop below the desired set point. The controller is factory programmed to
automatically activate the heater and the evaporator fan when the cellar temperature is
below the desired set point (parameter SET) minus the temperature differential
(parameter HY). For example, if the set point (Set) is 55 , and the differential (HY) is 4,
the heater will energize when the cellar temperature reaches 55 minus 4 = 51°F, and
turn off when the cellar reaches 55°F. Refrigeration will be activated when the cellar
temperature reaches 55 plus 4 = 59°F. If a tighter range is required, the HY should be
set to "2" for the heating season. If an optional bottle probe is used to maintain the
cellar temperature, the factory setting for HY is "1", and adjustment is not required.
There are two heating element options: 900W and 1800W. An application chart is
shown below to assist in selecting the correct wattage. For the majority of applications,
the 900W heater is recommended.

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.

IV. Troubleshooting

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)

The cooling unit enters a timed
auto- cycle 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.

General Conditions



Cooling Unit Runs Constantly

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.

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 Minim um Set Point on the cooling unit



Cooling Unit Is Producing Large Amounts of Condensate or 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 channeled outside the cooling unit.
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 excess condensation, 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.

4. Check to make sure the cellar has airtight seals, including the door(s), light
fixtures, and all walls, ceiling and floor.

34



The HA2 Alarm has been triggered

The cooling unit is designed to measure the temperature of the condenser coils and, if

°

the temperature exceeds 140

F for more than 2 hours, the HA2 alarm will display on

the control panel.
If this alarm happens when you first receive and start operating your CellarPro

cooling unit, check for appropriate installation and ventilation (Chapter II). Also,
make sure that there aren’t any obstructions to the intake and/or exhaust vents. If your
wine cabinet has a grill, remove the grill and/or any other obstructions above (top
vent) or behind (back vent) the cellar.

If the alarm happens in conjunction with hot ambient conditions, we recommend
doing the following:

1.

Raise the Minimum Set Point to 60°F until temperatures cool down

2.

Increase the FON setting

If the cooling unit has been operating for several months without any problems and the
alarm occurs, check the condenser filter and clean or replace if necessary.



The LA2 Alarm has been triggered

As noted above, the cooling unit is designed to measure the temperature of the
condenser coils and, if the temperature drops below a certain point, the LA2 alarm will
display on the control panel. Please contact CellarPro when the LA2 alarm has been
triggered.

 The Cooling Unit Won’t Turn On
The cooling system is programmed with a 3-Minute Delay at Startup to protect its

internal components.
