In addition to energy efficiency, and the previously-mentioned environmental-friendliness, thermoelectric cooling is very quiet, making it ideal for homes and offices. While thermoelectric cooling offers many benefits, the cooling performance of thermoelectric units tends to strongly correlate to the environment in which the units are located. In other words- the cooler the environment, the better the cooling perfromance of the wine cooler. In light of the above, it is helpful to note that this wine cooler was designed for use in a "room temperature" environment (i.e., with ambient temperatures in the mid-70's). Please note that this appliance is a wine cooler- not a refrigerator. If you feel that the wine cooler is not cold enough, we suggest making sure the unit is on its lowest setting, giving the unit at least 24 hours to cool, and making sure the unit is not exposed to direct sunlight or excessive heat. Thermoelectric Wine Cooler Model: TWR181ES Thank you for choosing this quality EdgeStar product. This quick-reference guide is designed to supplement your owner's manual and help you get your wine cooler up and running as fast as possible. For more detailed information, please check your owner's manual. If you would like more help or troubleshooting for common issues, feel free to visit us online at Included accessories This wine cooler ships with four wire shelves (installed), four adjustable leveling legs (installed), and a "water box'" For complete unpacking instructions, see the owner's manual. Power and controls Once your wine cooler is completely unpacked and set up, you can plug it in and begin using it. Operation of the control panel is quite simple- use the "A" and "V" buttons to select your desired temperature. "A" means up and "V" means down. The buttons on the right correspond to the "lower zone" and the lower temperature read-out. The buttons on the left correspond to the "upper zone" and the upper temperature read-out. Once the display shows your desired temperature, stop adjusting the temperature. The temperature you selected will blink in the display- then the display will change to reflect the actual temperature inside the unit. If you would like to review your desired temperature again, simply press the "A" or "V" button again. To turn the light on or off, locate the light switch (inside the unit on the upper right side. This switch toggles the LED light on and off. There is one light switch that controls both zones. Temperature range The upper zone has a temperature range of 45°-54° (F) under ideal conditions (see Notes on thermoelectric cooling for more info). This zone is ideal for white wines. The lower zone has a temperature range of 54°-64° (F) under ideal conditions and is ideal for red wine. As detailed above, you can set your desired temperatures using the control panel. For your reference, many wine experts suggest that 55°F is an ideal temperature for storage of most varieties of wine. However, the ideal drinking temperatures for most wines differ. We suggest you do a little research to determine at what temperatures you most enjoy your favorite wines, but we suggest temperatures in the low 50's for white wines and "room" temperatures (or slightly cooler) for red wines.
