Outlet Port Interior
1. Clean the humidifier outlet port by using a lint-free cloth dampened with a solution of mild
dish washing detergent (e.g. Dawn Ultra) and potable water. A ratio of 1 teaspoon of Dawn per
gallon (3.8 liters) of water is required. Insert the cloth approximately 7 cm (2.75 inches) into the
outlet opening while cleaning.
2. Wipe with a new lint-free cloth dampened (not dripping) with potable water for one minute,
turning the cloth frequently, to remove all detergent residue.
3. Allow to air dry completely before reconnecting to the therapy device.
Water Tank and Lid
Clean the water tank and lid before first use. Hand wash the water tank and lid daily.
1. Turn the humidifier setting to off. Turn the therapy device off. Allow the heater plate and water
to cool.
WARNING: Allow the humidifier heater plate and water to cool down for approximately 15
minutes before removing the water tank. A burn may result from touching the heater plate,
coming in contact with the heated water, or touching the tank pan.
WARNING: Before cleaning the humidifier, always remove from the therapy device.
WARNING: Empty and clean the water tank weekly to prevent mold and bacteria growth.
Wipe the middle seal completely.
2. Open the humidifier lid with the release lever, and then slide the water tank out of the humidifier
enclosure.
3. Press the tab in the hole on top of the tank in toward the front of the tank. Gently remove the
tank lid from the tank base. Empty any remaining water from the base of the tank.
4. Immerse in a solution of warm potable water and a mild liquid dishwashing detergent (such as
Dawn Ultra Dishwashing Liquid) and agitate for one minute. A ratio of 1 teaspoon of mild liquid
dishwashing detergent per gallon (3.8 liters) of water is required. Gently wash the middle seal.
Rinse the parts with potable water for one minute following hand washing.
5. Allow the parts to completely air dry.
6. Inspect the parts to ensure they are visibly clean. Wipe the parts completely with a damp,
lint-free cloth if necessary.
7. Inspect the tank and middle seal for damage. If any part is damaged, replace it.
8. Reassemble the tank by placing the hinges on the tank lid over the 2 tabs on the back of the
tank base. Close the lid until the tab on the lid snaps back under the lip in the tank base. Inspect
the tank. When it is closed correctly, the lid should be seated completely on the middle seal and
it should sit snugly on the tank base so the tab can easily snap back in place.
9. Before using the tank, fill it with distilled water (per the directions in the "Daily Use" section) no
higher than the maximum fill line located on the front and sides of the tank.
10. Inspect the water tank for any leaks or damage. If the water tank shows signs of wear or
damage, contact your home care provider for a replacement.
Note: If the lid does not close easily onto the base, separate the two parts, reassemble the
tank, and inspect it again. Never use the water tank if the tank lid does not fit comfortably on
the tank base.
