INTRODUCTION
Customer Service
Thank you for purchasing a WhisperKOOL 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
WhisperKOOL.com.
Using the Manual
This 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 WhisperKOOL Cooling System?
The WhisperKOOL 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 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.

Platinum Split
Pump Down Cycle
WhisperKOOL’s split systems operate on a pump down cycle dierent from traditional air conditioners. As such, there is no wiring
between the condensing unit and evaporator unit.
WhisperKOOL 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 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*
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.
*Further system operation information is available on page 39.
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
4-6°F SUBCOOLING REQUIRED FOR WARRANTY APPROVAL
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.

BEFORE YOU START 1-800-343-9463
1. Inspect all components prior to installation. If damage is found, please contact your distributor or WhisperKOOL Customer
Service at 1-800-343-9463.
2. The evaporator unit requires a dedicated 115V, 15-amp circuit. The 4000 condenser requires a dedicated 115V, 15-amp
circuit. The 8000 condenser 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. WhisperKOOL requires that all split systems be installed by a certified HVAC-R technician only. NATE or equivalent is
recommended.
If you encounter a problem with your WhisperKOOL system, please refer to the Troubleshooting Guide. If you have any further
questions or concerns, or need assistance, please contact WhisperKOOL’s Customer Service at 1-800-343-9463. Please be sure all
testing has been completed prior to contacting Customer Service. Please have your results ready for your representative.
