SYSTEM OPERATION (WHISPERKOOL 2500)
Initial Start-Up
When the unit is rst turned on, the control will briey display all symbols and the green snowake symbol will
appear if the unit is calling for cooling. There may be a brief delay prior to the evaporator fan turning on, as it
will not start until the probe temperature drops to below 70°F. When the fan is activated, the fan symbol will be
displayed. The Advance Product Safety Technology (APST) ensures that in the possible event of a cooling deciency,
the heat from the in-cabinet fan will not raise the temperature of the wine cellar, which could otherwise have an
adverse eect on the wine aging process.
Normal System Cycle
After the bottle probe has reached the set point (all units are shipped with the set point of 55°F and a dierential of
1 degree), the compressor and the condenser fan will turn o, but the in-cabinet evaporator fan will continue to run
for about 1 minute (This is a feature of the WhisperKOOL Humidity Management
(WHM) system). The WHM is an adjustable feature that allows the customer the convenience of managing the
humidity enhancement of their wine cellar. It is one of the many customer preference selection features that allow
the customer the ability to ne-tune the controls.
Anti-Frost Cycle
The Anti-Frost Cycle is a precautionary measure, as icing or frosting of the coil does not occur during normal
operation. During the defrost cycle, the in-cabinet fan will provide airow across the coil, which will evaporate any
frost accumulation.
Bottle Probe Failure Protection
Should a bottle probe fail, the Advance Product Safety Technology (APST) will automatically transition the
refrigeration compressor cycles to a pre-determined time series (based on laboratory testing), which will ensure
that the temperature is kept within the safe range.
Control Panel
The Control Panel is designed to give the user the ability to monitor and change cellar conditions when the
evaporating unit is placed in a remote location.
