PARTS
Warm or Cold Humidication Selection
Select humidifying temperature based on need. Warm humidity will use more 
power but will humidify your room quicker.
NOTE: It may take 10-15 minutes before warm humidity is created. The mist may 
not feel especially warm due to the fact it is so ne and is cooled rather quickly 
from the air in your home. 
TEST: To test if the warm mist is functioning properly, place the unit in a 200 
square foot room or smaller and close the door. Allow the unit to run for 
approximately 30 minutes or more. Reenter the room - if unit is functioning 
properly - the room will feel moderately warmer.
TEST: Another way to check if the unit is functioning properly is by feeling along 
the base of the unit. The base should feel warm to the touch.
Water Shortage Indicator
When the unit is low on water the Rell LED on the front panel will light up, 
and the unit will shut off. Simply add more water to continue use. Unit will 
automatically resume running when water tank has been relled.

knob on the front panel.
