Principles of Operation
Air from the cellar is drawn over an evaporative drip pad that is saturated with water from a distribution tray. As the air passes through the pad, it absorbs moisture through the evaporation of the water. This raises the humidity of the leaving air that returns to the cellar. The humidistat, located in the cellar, will automatically turn on the humidifier whenever the cellar humidity is below the set point and turns it off when the cellar humidity reaches the set point. The recommended set point is 50% to 70% RH for wine cellars. This humidity level is high enough to prevent corks from drying out and low enough to prevent mold from forming.
Maintenance of the humidifier
A regular maintenance program prolongs the life of the humidifier and helps maintain proper humidity levels in the cellar. Frequency of cleaning and replacement of the drip pad depends on the inlet water conditions and the cleanliness of the cellar air. The drain system may also trap dust and dirt. When water no longer stays on the pad or mineral build-up has started to reduce airflow, the pad needs to be replaced. For these reasons we suggest you check the drain on a monthly basis and confirm there is a steady flow of water while the unit is in operation. Clean drain if needed.
Also monthly, check for unusual noise or vibration, which could be a sign that the debris may be trapped and needs to be removed. Check the humidifier’s installation operation and maintenance manual for more information on maintaining your Wine Guardian humidifier.
