Ultimate Series
MULTISPEED FAN CONTROL
Designed for wine cellars up to 1000 and 2000 cubic feet, the Ultimate 3300, 4400, and 8800 feature multi-speed fans. These
fans have a high setting for maximum performance in high-temperature (+110°F) environments and a low setting for super-quiet
operation.
Fan Speed Selector Switch (Low/Med/High)
The cooling unit fans operate on three speed settings: Low, Medium, and High. For optimum sound and energy eciency,
select the lowest fan speed that will maintain the desired cellar temperature. If the relative humidity is low, a higher fan speed
will cause less moisture to be removed during cooling. High speed is recommended for initial cellar cool-down, extreme
temperature conditions, and ducted installations.
Fan speed selection is determined by the amount of heat that needs to be removed from the cellar and the type of installation
(through-the-wall or fully ducted). Fan speed selection is based on cellar size, insulation ratings, door seals, and the desired wine
temperature. When initially installing the unit, set the fan speed to the High setting to quickly cool down the cellar. Once the
wine cellar reaches the desired temperature, a lower fan speed may be selected. In the event that the outdoor temperature rises
above 90°F (when exhausting to the outdoors), a higher fan speed may be required.
* To give you a feeling for decibels, a food blender at 3 ft. is 90 dBA, a garbage disposal at 3 ft. is 85 dBA, a vacuum cleaner at 10 ft. is 75 dBA,
normal speech at 3 ft. is 79 dBA, a dishwasher in the next room is 55 dBA, and a quiet night is 35 dBA.
