Initial Start-Up

When power is applied to the unit, the control will briey

display all symbols, and the Snow Flake symbol will

be displayed (if unit is calling for cooling). There may

be a brief delay prior to the evaporator fan turning on,

as the fan will not turn on until the evaporator probe

temperature drops below 70°F. When the evaporator

fan is activated the Fan symbol will be displayed. The

temperature control feature for the evaporator fan is a

feature applicable to WhisperKOOL. This is the Advance

Product Safety Technology (APST), which ensures that in

the possible event of a cooling deciency, the heat from

the indoor fan will not raise the temperature of the wine

cellar, which could otherwise have an adverse eect 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 dierential

of 1°F), the compressor and the condenser fan will turn

o, but the indoor fan will continue to run for about 5

minutes, which is a feature of the WhisperKOOL Humidity

Management (WHM) system. The WHM is an adjustable

feature which allows the customer the convenience

of managing the humidity enhancement of their wine

cellar. The WHM is one of the many Customer Preference

Selection features which allow the customer the ability to

ne tune the controls.

Anti Short Cycle

The Anti Short Cycle ensures that the unit will remain o

for a period of 5 minutes after the unit has reached the

set point to prevent short cycling of the compressor.

Anti Frost Cycle

The Anti Frost Cycle is a precautionary measure, as icing

or frosting of the coil does not occur during normal

operation. The system will go through a defrost cycle

every 4 hours. During the defrost cycle, the indoor fan

will provide air ow across the indoor coil, which will

evaporate any frost accumulation.

Low Ambient Conditions

If the condensing unit is installed outside (which will

allows the condenser to be exposed to low ambient

temperatures), the condenser fan may cycle on and

o. The purpose of the fan cycling is to maintain the

system high side pressure, which will ensure an adequate

refrigeration process.

Bottle Probe Failure Protection

In the event that a Bottle probe should fail, the APST

(Advance Product Safety Technology) will automatically

transition the Refrigeration Compressor cycles to a pre-

determined time series (based on detailed laboratory

testing), which will ensure that the product is kept within

the safe range.

Remote Control Panel (standard on ducted units)

The remote keypad is designed to give the user the

ability to monitor and change cellar conditions when the

evaporating unit is placed in a remote location outside of

the cellar.
