Q: How much water should I add to my evaporative cooler?

A: The amount of water required varies depending on the type of your device. To help determine the correct level, each evaporative cooler has a water level indicator. This indicator is located at the bottom of the drain. Add water until the scale indicates that the water reserve is full. If overfilled, water will flow out of the device
