INTRODUCTION
Customer Service
Thank you for purchasing a CellarCool cooling system. We strive to provide the highest-quality products and the best possible
customer service. If you have any questions about your system, please call us at 1-800-343-9463 or visit cellarcool.com.
Using the Manual
This owner’s manual is intended to assist in the proper maintenance of the cooling system. In order to ensure the longevity of
your cooling unit, the equipment should be installed as outlined in the technician’s manual. It is also vital to establish a proper
care and maintenance schedule. Please read and review this manual carefully and keep it for future reference.
What is the CellarCool Cooling System?
The CellarCool cooling system is a specialized refrigeration system designed for one purpose only: to maintain the optimal
temperature and humidity levels conducive to the proper storage and aging of ne wines. This system produces minimal in-cellar
noise and has the most lenient exhaust requirements. An exterior housing is required for outdoor condensing unit installations.
How Does the Cooling System Work?
Similar to the air conditioning systems used for homes, the evaporator unit (fan coil unit) and condensing units are installed
in separate locations and are connected by a refrigerant line set. The evaporator portion is commonly installed in the wine
cellar, with the condensing unit is located either outside or in a remote indoor location that is ventilated. An exterior housing is
required for outdoor condensing unit installations.
Temperature Setting
The system is designed to maintain a cellar temperature of 55°F as long as the ambient temperature does not exceed 110°F.
WARRANTY REGISTRATION
In order to activate the warranty of your system, the verication and operational
documentation must be completed by the certied refrigeration technician

QUICK START GUIDE*
Pump Down Cycle
CellarCool’s split systems operate on a pump down cycle dierent from traditional air conditioners. As such, there is no wiring
between the condensing unit and evaporator unit.
CellarCool units utilize a solenoid valve on the liquid line and a low-pressure switch on the suction line. When the thermostat calls
for cooling, the solenoid valve opens, permitting the ow of refrigerant. The low-pressure switch then signals the compressor to
cycle on.
When the cellar reaches the desired temperature and the thermostat is satised, the solenoid will close, stopping the liquid
refrigerant ow to the TXV valve. The compressor will continue to operate until most of the refrigerant on the low side boils o
and is pumped through the compressor into the condenser coil and receiver. As the suction pressure falls below the pressure
control setting, the low-pressure switch will signal the compressor to cycle o. Most of the refrigerant is now stored between the
condensing unit and receiver.
…………………………………………………………………………………………………
WARNING: Do not utilize a ground fault interrupter, as it will prevent
the unit from drawing the necessary amperage to start the unit.
TXV Adjustments
A. A TXV adjustment may be necessary based on ambient temperatures in the cellar and at the condensing unit.
B. Adjust the TXV until the total superheat measured at the suction line service valve is 20-30°F.
C. Under normal operation, with the wine cellar at 55°F and the ambient temperature at 85°F, the low side pressure should be
between 28-32 PSI and the high side should be between 145-155 PSI.
TXV
The TXV is preadjusted at the factory. If the superheat is not within
20-30° at the service valve, the TXV will need to be adjusted.
ADJUSTING THE TXV
Use a ⁄” hex key to remove the cap from the TXV superheat
adjustment port. With the cap removed, insert the hex key into
the superheat adjustment port. Increase superheat by turning the
hex key clockwise. Decrease superheat by turning the hex key
counterclockwise.
Liquid Line King Valve
This location is used to charge the system with liquid refrigerant
and identify the high side pressure of the system.
Calculating Subcooling
To determine the subcooling of the system, calculate the dierence
between the high side pressure of the system (converted to
temperature) and the temperature of the liquid line. The temperature
of the liquid line will be taken at the outlet of the receiver.
*Saturation temp — liquid line temp
4-6°F SUBCOOLING REQUIRED FOR WARRANTY APPROVAL
*Further system operation information is available on page 32.

BEFORE YOU START
1. Inspect all components prior to installation. If damage is found, please contact your distributor or CellarCool Customer
Service at 1-800-343-9463.
2. The evaporator unit requires a dedicated 115V, 15-amp circuit. The 3500 condensing unit requires a dedicated 115V, 15-
amp circuit. The 5000 condensing unit requires a dedicated 115V, 20-amp circuit. Use a surge protector with the unit. Do
not use a GFI (ground fault interrupter) line.
3. No communication cable is required between the evaporator and condensing unit.
4. You are REQUIRED to install a drain line to remove condensation from the evaporator unit.
5. The warranty is not active until a warranty checklist has been received, reviewed, and approved.
6. The system is intended for use in properly designed and constructed wine cellars. Hire a professional wine storage
consultant with a valid contractor’s license to build your wine cellar.
7. CellarCool requires that all split systems be installed by a certified HVAC-R technician only. NATE or equivalent is recommended.

24V THERMOSTAT CONVERSION KIT WIRING INSTRUCTIONS
The 24V Thermostat Conversion Kit requires a standard 18-5 thermostat wire to be run from the evaporator unit to the
thermostat. The white wire will not be used, as there is no heating function. (Some thermostats need a common wire and some
do not; the unit is equipped with a common wire if needed.)
If the system is equipped with the Cold Weather Start Kit a standard 18-2 thermostat wire must be run between the evaporator
unit and the condensing unit.
24V Wiring Connections (Evaporator)
1. Route a standard 18-5 thermostat wire into the evaporator unit.
2. Locate the wire thermostat connection cable inside of the evaporator unit.
3. Connect the wires according to color (yellow to yellow, red to red, green to green, and blue to blue).
4. If the system is equipped with a Cold Weather Start Kit, connect one wire from the 18-2 thermostat wire to the low-voltage
yellow wires (2). Then connect the other 18-2 wire to the blue low-voltage wires (2).

6. If routing through a wall, cut out an access
hole for the line set, drain line, and power wires.
7. Raise the evaporator to the installation location. Align the rear key
holes with the mounting screws and mount the unit.
8. Using a ¼” wrench or socket, tighten the top mounting screws.
9. Using ¼” and ½” copper tubing, route the liquid and suction lines
through the knockouts in the housing. Be sure to extend the
tubing far enough outside of the housing to extend through the
wall if necessary. NOTE: ½” copper tubing will slip over the ⁄”
suction line on the evaporator for an easy connection.
10. Remove the solenoid coil and wrap the solenoid valve in a wet rag
to prevent overheating.
11. To prevent oxidation, purge the system with nitrogen.
12. Braze the copper tubing to the connections on the evaporator
unit.

13. Insulate the suction line using Armaex or similar insulation.
14. Using the cable ties and cable tie mounts provided, secure the drain line to the bottom of the housing to ensure a downward
slope.
15. Route the power wires into the unit through the knockout.
16. Following the supplied wiring diagram on page 12, connect thermostat wires.
17. Connect the green wire to the green wire, the black wire to the black wire, and the white wire to the white wire.
18. Install the supplied black strain relief to secure the power wires in the housing.
19. Secure all wiring neatly and as close to the left wall as possible in order to minimize airow obstruction.

DRAIN LINE
Condensation Drain Line (not provided, but required)
The condensation drain line tube moves excess condensation from the evaporator unit to a proper discharge
location. It is important for the drain line tube to be properly connected in order to prevent leakage and other problems associ-
ated with excess condensation.
Failure to use the condensation drain line tube will void the warranty on the unit.
Drain Line
All systems come with a drain line connection tee and two 90-degree fittings. The unit is equipped with a ½” OD barbed fitting
coming from the drip tray. (NOTE: ½” ID clear PVC tubing will need to be purchased and installed by the installing technician.)
Installation of the drain line is mandatory, whether it leads through the wall and out of the cellar or remains inside the cellar.
During operation, the cooling system will strip excess water from the air in order to maintain the proper level of humidity within
the cellar. However, in extreme humidity, additional condensate will be removed; thus the drain line will prevent overflow and
leakage by discharging the excess condensate.
Routing the tubing out of the unit:
Cut a small piece of ½” tubing and connect one
end to the drip tray port and the other to a
90-degree fitting. (This will direct the tubing
toward the back of the unit where the tube will
exit the unit.) Be sure to extend the tubing far
enough outside the housing to extend through
the wall if necessary.
If routing out of the rear: Cut a piece of tubing
long enough to protrude out of the knockout on
the back side of the unit.
If routing out of the bottom: Cut a piece of
tubing long enough to reach the knockout in
the bottom of the unit and install the supplied
90-degree fitting. (This will direct the tubing out
of the bottom of the unit without the risk of
kinking the tubing.) DO NOT USE TEE WHEN
ROUTING OUT OF THE BOTTOM.
Routing to discharge location if routed out
of the bottom:
Connect the drain line directly to the second
90-degree barb fitting previously installed. Route
the drain line to an appropriate drain location.
No tee is required if draining through the
bottom of the unit.
Routing to discharge location if routed out of the rear:
Insert the middle barb of the barbed tee fitting into the end of the drain
line coming from the evaporator. Rotate fitting so tee is in the orientation
shown in the diagram below. Connect a 3-inch piece of ½” drain line to
the barb on top. Connect the remaining “long” piece of drain tubing to
the bottom barb of the tee. Route the drain line to an appropriate drain
location.
NOTE: The fitting should be placed
vertically with the 3” cutout facing
up.
Failure to install the drain line
voids the warranty.
To prevent mold from growing,
allow the drain line to hang
above the water line.
WRONG: Drain line is under water.

PREPARING THE CONDENSING UNIT
Electrical Needs
The 3500 condensing unit requires a dedicated 115V, 15-amp circuit. The 5000 condensing unit requires a 115V, 20-amp
circuit. The unit draws a large inrush current for about 1 second the instant the compressor starts. With a dedicated circuit and
circuit breaker, the condensing unit will have sucient power for eective operation. (The compressor is controlled by a lowpressure transducer mounted on the condensing unit. This feature eliminates the need for wiring between the evaporator unit/
fan coil unit and the condensing unit.)
• Ensure the voltage supplied matches the rating specied on the unit spec label.
• Provide a non-GFI dedicated circuit and an appropriate outlet for the evaporator unit.
• Provide a dedicated circuit and circuit breaker for the condensing unit.
• Provide a weatherproof disconnect for the condensing unit if it is located outside.
Power surges and spikes can damage sensitive electrical equipment. CellarCool recommends plugging the unit into a surge
protector or power conditioner in order to protect your system. As outlined in our terms and conditions, power surges and spikes
are not covered under warranty.

INSTALLING THE CONDENSING UNIT
The condensing unit can be installed inside a well-ventilated area of the home, but is typically installed outside. Exterior
applications will require the use of a protective housing. The amount of sun exposure should be considered when selecting
the placement of the condensing unit .The 3500 condensing unit requires a dedicated 15-amp circuit (non-GFI). The 5000
condensing unit requires a 20-amp circuit (non-GFI). Make sure there is a minimum of three (3) feet of horizontal clearance in
every direction around the unit (ve feet is ideal). The unit may either be hard-wired or plug-in, depending on local electrical
codes.
Indoor condensing unit installations: Inside installations require special consideration, as there must be adequate
ventilation to remove the heat created during normal operations. An exhaust port with fan may need to be installed to
ensure that heat is eectively removed from the utility room. There must be a return grille or provision for 500 - 600 CFM
of cool air to enter the room to replace the exhausted air. Unobstructed airow to and from the unit is a critical factor in
the unit’s overall performance. Make sure there is a minimum of three (3) feet of horizontal clearance in every direction
around the unit (ve feet is ideal). This will assure that the unit can move the air around the room in an ecient manner.
Outdoor condensing unit installations: You must utilize the exterior condensing unit housing for outdoor installations.
Place the condensing unit on a solid foundation in a location with adequate ventilation. Make sure there is a minimum
of three (3) feet of horizontal clearance in every direction around the unit (ve feet is ideal). The unit should be
elevated 18 inches in order to avoid any possible ooding or damage by animals, and should be clear of leaves, dirt, and
other debris.

INSTALLING THE CONDENSING UNIT
DO NOT BLOCK airow through the exterior housing. This will restrict airow andvoidthe warranty.
Refrigerant Piping Overview
• Using the charts and illustrations found above, route the line set between the evaporator unit and condensing unit. Be sure to
reference the chart for correct line set sizing. All horizontal suction piping should be pitched toward the condensing unit half
an inch for every 10 feet of pipe. When installing and routing the line set, cap both ends of each tube to prevent debris from
entering the tubing.
• Prior to connecting the piping to the evaporator and condensing units, loosely connect a refrigerant manifold to the suction
and liquid line service valves.
• Purge the hoses with dry nitrogen and tighten the hose connections.
• Remove the service valve caps and turn the valve stem clockwise half a turn to unseat the valve and open the service
port. Keep the piping ports sealed until ready to braze.
• Purge the ttings with dry nitrogen at a slow rate to prevent formation of highly abrasive copper oxide.
• Perform all brazes.
• Pressure test the system and check for leaks.
• Insulate the suction line using wall cellular insulation or equivalent. Seal all seams with Armaex 520 foam insulation adhesive
or equivalent. Wrap each seam using line set tape.
Liquid Line Piping Procedure
• Refer to the line set piping chart for liquid line size measurements.
• Braze a short piece of copper tubing to the liquid line service valve.
• Connect the supplied refrigerant drier to the tubing.
• Downstream from the drier, connect the moisture-indicating sight glass in an easily visible location.
• Run the tubing to the evaporator unit and attach to the liquid line connection on the evaporator unit.
Suction Piping Procedure
• Connect an appropriately sized suction line to the suction line service valve on the condensing unit.
• Run the pre-insulated suction line to the evaporator unit and attach to the suction line connection on the evaporator unit.
Brazing Procedure
• Energize the evaporator unit and set the thermostat to call for cooling.
• Verify that the setpoint on the control is set low enough to allow the unit to run for the entire length of the brazing,
evacuation, and charging procedure.
• Remove the valve depressors from the gauge hoses on a four-valve manifold.
• Connect the manifold to the low-pressure service valve port on the condensing unit and a nitrogen tank.
• Open the suction line service valve and purge the system with nitrogen.
• Braze all connections and cool o quickly.
• Connect the high-pressure hose from the manifold to the liquid line service valve port.
• Pressure test the system at 150 psi for 20 minutes.
• Check all braze joints with leak detector or soap bubbles.
• Release the nitrogen once it is conrmed that there are no leaks.
Evacuation
• Remove the nitrogen tank from the manifold and attach the manifold to the refrigerant tank.
• Mid-seat both service valves.
• Install service caps on the valves.
• Energize the liquid line solenoid valve.
• After conrming that there is fresh oil in the vacuum pump, connect the ⁄” hose from the manifold to the pump.
• Start the pump and run it until the micron gauge on the evaporator unit reads 500 microns or less.
• Disconnect the vacuum pump from the system.
www.cellarcool.com | Page 29
INSTALLING THE CONDENSING UNIT (continued)
• Break the vacuum by pressurizing the system to approximately 5 PSI with R-134a refrigerant.
• Remove the micron gauge from the access valve.
Charging
• With the power o to the condensing unit, admit liquid refrigerant through the liquid line service valve until the refrigerant
stops owing.
• Turn on the circuit breaker for the condensing unit. The compressor should turn on if the pressure in the suction line is above
20 psi.
• Add refrigerant (in vapor form) to the low side of the system through the suction line service port.
• Observe the sight glass. If bubbles are present, add more refrigerant (in vapor form) to the low side.
• Once the sight glass is clear, check the superheat at the outlet of the evaporator unit. Adjust the TXV until the superheat is
between 20-30°F degrees.
• Under normal operation, with the wine cellar at 55°F and the ambient temperature at 85°F, the low side pressure should be
between 28-32 PSI and the high side should be between 145-155 PSI.
Finalizing the Installation
• Conrm that the entire suction line from the TXV to the suction line service valve is insulated using cellular insulation or
equivalent. Seal all seams with Armaex 520 foam insulation adhesive or equivalent.
• Conrm that the control is displaying the correct temperature.
Charging Information
A. Energize the solenoid valve on the evaporator unit by plugging the unit in and adjusting the thermostat to call for cooling.

NOTE: A 12”x12” return air lter grille must be installed to prevent contaminants from entering the cooling system. Supply duct
must be insulated so it does not sweat or pick up heat.
www.cellarcool.com | Page 31
SYSTEM OPERATION
The cooling system is equipped with the hardware needed to support a 24-volt air conditioning thermostat (not included).
Initial Start-Up
Set the thermostat to COOL and fan switch to AUTO. Lower
the setpoint to the desired cellar temperature. (A temperature
of 55°F is the recommended setpoint.) See thermostat
instructions for details.
Normal System Cycle
The thermostat should turn the cooling system on when it
senses a temperature one (1) degree higher than the setpoint.
See thermostat instructions for details.
Anti-Short Cycle
Most thermostats have a safety feature that will prevent
the condensing unit from cycling on and o within a short
period of time. During the anti-short cycle, the condensing
unit will typically remain o for 5-7 minutes. See thermostat
instructions for details.
Fan Operation
If the fan switch on the thermostat is in the AUTO position, it
will run only during the cooling cycle. If the fan switch on the
thermostat is in the ON position, the fan will continuously run
until the switch is set back to the AUTO position.
The condensing unit controller is preset at the factory. The
cut-in pressure is preset to 25psi and the cut-out pressure
at 15psi. During low ambient temperatures (40°F or below),
it will be necessary to adjust the cut-in pressure to 1015psi (15psi is preferred) and the cut-out to 5psi to ensure
compressor startup. See page 34 for instructions on adjusting
the cut-in and cut-out pressures of the condensing unit.
NOTE: To ensure correct system operation, the 24V thermostat
must be placed inside the wine cellar, preferably in a central
location away from any airow.
Anti-Frost
Systems equipped with a 24V thermostat conversion kit do
NOT have an anti-frost feature. To reduce the possibility of the
evaporator coil icing up, avoid setting the thermostat lower
than 55°F.
Operation in Low Ambient Temperatures
The condensing unit comes equipped with a LAC (Low
Ambient Control). The LAC is a three-way modulating valve
that responds to discharge pressure. When the discharge
pressure falls below the valve’s dome pressure, the valve
modulates open to the discharge port which allows discharge
gas to bypass the condenser. Mixing the discharge gas with
the liquid creates high pressure at the condenser outlet,
reducing the ow and causing liquid to backup in the
condenser. Flooding the condenser reduces the area available
for condensing. This reduction in condenser surface area
results in a rise in condensing pressure during cold ambient
conditions.

Care and Cleaning of
Air Cooled Condensing Units
Introduction
Proper care is essential to assure good life of condensing
units. Dirty or damaged condensers will reduce the
efciency and capacity of the system.
Care must be taken in choosing solutions to be used for
cleaning condensers and condensate pans. Chlorinated
cleaners and anti-bacterial cleaning agents can be
damaging and should be avoided. Caustic and acidic
cleaners should be avoided as well. Failure to do so
may accelerate component corrosion and ultimately
lead to component failure.
Condenser Coils
There are many commercially available condenser coil
cleaners on the market. Coil cleaners should be designed
to remove build-up on ns and coils. Coils should be
thoroughly rinsed of the cleaners once cleaning has
been completed. Follow the manufactures instruction
for proper usage. Preventive maintenance and routine
cleaning of coils is important to assure good life.
When cleaning the coil, an absorbent type material
should be placed under the area to be cleaned in
order to capture most of the cleaning compound, thus
minimizing any type of chemical attack.
Condensate Pans
Condensing units with condensate pans and condensate
tubes are designed to evaporate condensate water
only. Other ingredients introduced into the condensate
pan can accelerate pan and/or tube corrosion. As
foreign agents are introduced into the condensate pan,
condensate water will be evaporated leaving the foreign
agent behind. This can lead to a high concentration of the
agent and possible corrosion of the tubing and/or base.
October 2006
Coil cleaning agents must not be allowed to drain into
the condensate pan as this may cause damage. Upon
completing the coil cleaning, be certain that all residue
is removed from the condensate pan.
Only non corrosive cleaners should be used to assure
good life of the condensing unit components. No
hydrocarbon based cleaners should be used to clean
the unit. Bleach solutions must be avoided due to its

ACCESSORIES FOR COOLING UNITS
CellarCool offers accessories to enhance and customize your wine cooling unit.
Condensate Pump Kit
The condensate pump kit automatically removes water that drips out of the evaporator unit’s drain line. The pump is controlled
by a float/switch mechanism that turns the pump on when approximately 2¼” of water collects in the tank, and automatically
switches off when the tank drains to approximately 1¼”. The condensate pump kit allows the excess condensate to be pumped up
to 20 feet away from the unit.
Exterior Housing
If the cooling unit is installed outside, it will need protection from sun, wind, and rain. The exterior housing protects the condensing
unit portion of the split system from the elements when installed outdoors.
Accessories can be purchased at www.cellarcool.com
