WARNING
The evaporator unit (fan coil unit) must be insulated using the insulation blanket provided in
accordance with this manual. Refer to the insulation blanket installation instructions.
Failure to follow the instructions provided will result in a poor vapor barrier, water
damage, rust, and system corrosion which will void the warranty on your unit.
The evaporator unit (fan coil unit) must be insulated using berglass insulation (R13 or higher)
in addition to the provided insulation blanket. This includes the cavity between the ceiling
joists. A warm attic environment will reduce the capacity of the cooling system, as the system
will absorb heat from the attic in addition to the heat load from the wine cellar. This, in eect,
will signicantly reduce the cooling system’s ability to cool the wine cellar.
Failure to properly insulate the evaporator unit may cause condensation to form on the
surface of the housing and water damage to the surrounding structure, the cooling unit, and
possibly the wine cellar.
To avoid these issues, install the insulation kit and insulate the surface of the evaporator unit
that is located outside of the wine cellar using berglass insulation.
*Additional insulation is required!

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 1-855-235-5271 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 verication and operational
documentation must be completed by the certied refrigeration technician
installing your system and submitted via mail, fax, or e-mail.

Pump Down Cycle
CellarCool’s twin split systems operate on a pump down cycle which diers from traditional air conditioners. As such, there is no
wiring between the condensing unit and evaporator units. CellarCool twin systems utilize a solenoid valve on the liquid line in
each evaporator unit and a low-pressure switch on the suction line at the condensing unit. When the thermostat calls for cooling,
the solenoid valve opens, permitting the ow of refrigerant to each of the evaporator coils. Once the pressure of the low side of
the system rises above 20 psig, the low-pressure switch then signals the compressor to cycle on.
When the cellar reaches the desired temperature and the thermostat is satised, 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.
QUICK START GUIDE*
*Further system operation information is available on page 37.
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 dierence
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
5-9°F SUBCOOLING REQUIRED FOR WARRANTY APPROVAL
TXV
The TXV is preadjusted at the factory. If the superheat is not
within 8-12°F, 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.
TXV Adjustments
A. A TXV adjustment may be necessary based on ambient temperatures in the cellar and at the condensing unit.
B. Superheat must be measured at EACH evaporator.
C. Adjust the TXVs for EACH unit until the superheat is 8-12°F. (Total superheat should be 20-30°F.)
D. Under normal operation, with the wine cellar at 55°F and the ambient temperature at 85°F, the low side pressure should be
between 78-82 psig and the high side should be between 300-330 psig.
