Fan running continuously
• Float is obstructed
• Humidity level is set to highest
position
• Humidity level has reached the
desired level yet
• Free float from obstruction
• Setting the humidity to highest position (65%)
causes the fan to run continuously Adjust to a
level lower
• Continue to run until desired humidity level is
achieved. This may take up to 48 hours initially
Poor evaporation of water
• Check Filter message (CF) mes-
sage flashing
• Mineral buildup on filter (wick)
• Change to a new wick
NOTE:
Local water varies from area to area and
under certain conditions minerals will build up more
rapidly in the wick
• Unplug unit for 1-2 minutes to reset CF function
Neither bottle emptying
