Where Is the Fill Line? The chamber included with the purchase of the DreamStation humidifier has an orange fill line printed below the rim on either side of the chamber. The fill line on the replacement water chamber is in the same location, however; the line is printed in clear letters instead of orange letters. Travel Tips Do not move the humidifier when the chamber is filled with water. Always remove the tank from the humidifier and extract all of the water when preparing to travel. After the tank has been emptied, let the chamber air dry completely away from direct sunlight. When all the equipment is dry, place the device in a carry-on bag to help protect the unit. Per the manufacturer, the carrying bag cannot guarantee the safety of the equipment when checked as luggage, so use the bag as a carry-on only. How to Access the Water Chamber?

The panel will open completely, exposing the water chamber. Cautiously remove the water chamber with both hands, place it on a flat surface to fill with water, and return the chamber to the humidifier. Do not fill the water past the maximum fill line. 1122520
