Thank you for purchasing a WhisperKOOL cooling system. We strive to provide the highest-quality products and the best possible customer service. WhisperKOOL Customer Service is available Monday through Friday from 6:00 a.m. to 4:30 p.m. PST. If you have any questions about your system, please email us at Support@WhisperKOOL.com.
Page 6: Quick Start Guide
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 flow of refrigerant. The low-pressure switch then signals the compressor to cycle on.

Insulation Insulation is REQUIRED in order to properly use WhisperKOOL products. It is vital that all walls and ceilings be insulated to keep the cellar temperature as consistent as possible during the summer and winter months. Standard fiberglass or rigid foam insula- tion is normally used in cellar construction;...
Page 12 In cases where glass doors are used and the room size is close to the recommended system size, the next larger size WhisperKOOL system should be used. This will compensate for the insulation loss due to the lower insulation rating of glass.

Page 15 There are several factors such as glass, stone, and concrete which will change the required amount of BTUs needed to properly cool your wine room. We strongly recommend utilizing the cellar wizard on the WhisperKOOL website in order to ensure you are selecting the proper cooling system for your application.
Page 16: Fan Speed Switch
LIQUID-MEASURING THERMOSTAT SYSTEM (BOTTLE PROBE) WhisperKOOL cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating probe contains a sensor chip, which communicates back and forth with the thermostat. This results in a consistent temperature setting and accuracy. Wine should be kept at a very precise, controlled temperature and humidity.

Page 18 24V WIRING CONNECTIONS (EVAPORATOR UNIT) 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.)18-5 thermostat wire (communication cable) must be run between the evapora- tor unit and the condensing unit.
