LIST OF MAIN PARTS

TECHNICAL SPECIFICATIONS

BEFORE EACH USE:
CHECK HUMIDIFIER PLACEMENT:
Place the Humidifier on an elevated, non-metallic, lint-free, waterproof, level surface at least 2 feet above the floor.
- DO NOT PLACE ON CARPET OR TOWEL. The fan vent is located on the bottom of the humidifier base. The fan vent MUST NOT be obstructed.
- DO NOT PLACE ON WOOD SURFACE or near furniture that can be damaged by too much moisture.

CAUTION
- DO NOT attempt to operate the humidifier without water in the Water Tank.
- DO NOT plug or unplug the Power Cord with wet hands, as electric shock could occur.
ALWAYS use fresh cool water when operating the humidifier.
- Remove the mist cover and fill with cool water only.
Note: DO NOT use distilled water. This item uses an electronic water level sensor to detect the water level in the tank. Distilled water is nonconductive, which could lead to a false water level reading.
ALWAYS HOLD THE UNIT WITH TWO HANDS WHEN FULL.
- DO NOT fill water past the MAX fill line.
- DO NOT use hot water.
- DO NOT pour water into the Mist Lid.
- Place the Mist cover back on the filled Base so the mist chamber lines up with the nebulizer in the base of the item.
- Plug the power cord into a wall socket and turn on the humidifier function by using the Humidity Control Button. Press 1x for Medium, 2x for high, 3x to run in sleep mode (Low mist output and lights off), 4x to power off.
- A Blue Indicator Light will illuminate, indicating what mist output setting the unit is being run in.
- SET THE CORRECT HUMIDITY OUTPUT: Adjust the mist output so the mist rises to be absorbed by the room air. If the mist drops quickly, use the lower output setting so the mist is rising up.
- When the humidifier runs out of water, a red indicator light will flash, and the mist output will stop. This is a safety feature to prevent the humidifier from possibly overheating and damaging the Nebulizer. Turn the humidifier off and unplug the unit before removing and refilling the water tank. When emptying the base, be sure to pour away from the fan outlet.

NOTE: The night light function can be operated independently without turning on the humidifier function.
Fragrance Mode: Press to control the optional Fragrance Mode. Fragrance Mode will run the unit’s fan to output an essential oil’s fragrance without running the humidifier function.
- 1 Touch – Fragrance Mode with indicator light on
- 2 Touch – Fragrance Mode off, indicator light off
Essential Oil Bottle: Remove the essential oil bottle from the underside of the Mist Cover. Unscrew the cap and add up to 2ml of desired essential oils before screwing the cap back on. Return the essential oil bottle to the underside of the Mist cover.
A NOTE ABOUT HUMIDITY
- To reduce excessive humidity or condensation, especially in small rooms, leave the room door open and adjust mist intensity to the low output setting.
- Too much humidity in the room may allow moisture to accumulate on surfaces where bacteria and fungi can grow. Moisture that gathers may also damage furniture and walls, especially wallpaper.
MAINTENANCE
Cleaning and disinfecting on a regular basis is important for maintaining the performance of your humidifier.
IMPORTANT: Water left in the tank or base when not in use may result in the buildup of mineral deposits and bacteria, which may inhibit the output efficiency as well as void the warranty. If water remains in the Water Tank for more than a day or two, bacterial growth is possible.

How long does the Crane EE-5401 run on a full tank?

Does the Crane EE-5401 use warm mist or cool mist technology?

What features make the Crane EE-5401 stand out?
