SOLUTION
Water dripping when refilling.
Cap not tight.
Water remaining on bottom of tank. Wipe tank or tilt to drain
before transporting.
Twist to firmly secure cap after filling tank with water.
Increased noise level.
Unit must be placed on a flat, level, hard surface. Make sure it is
NOT placed on a soft or absorbent surface.
Humidifier display not reaching
“auto” or desired humidity level.
There are a few things that can affect the reading.
The climate (example - if in a very cold climate, the furnace will
run frequently, letting dry air into the room).
The room may be too large and may be open to other spaces.
Try warm humidification, sometimes this increases the
humidity faster.
Also, unplugging it for a period of 5-8 minutes. Sometimes it is
possible to overload the unit when first getting the product and
trying out all the buttons.

Warm humidity is not produced.
It may take 10-15 minutes before warm humidity is created. The
mist may not feel warm due to the fact it is so fine and is cooled
rather quickly from the air in your home. Test by either feeling the
base of the unit which should be warm to the touch or by allowing
the unit to run for approximately 30 minutes on warm setting in
a closed 200 sq. foot room or smaller. The room should feel
moderately warmer if the unit is working properly.
The humidity has a bad smell.
Poor maintenance or dirty water: Clean the product thoroughly, and
fill it with fresh water. (see pg. E-10)
White dust is forming on
nearby furniture.
Hard water may deposit a certain amount of dust. Dust in the air
also settles because of added humidity in the room. Use distilled
water if this becomes a nuisance.

it will automatically restart when cooled down. If the unit does
not automatically restart, then allow the unit to cool and cycle the
power button to reset and start the humidifier.
Important: If the unit continues to display “OH” or shut down, there
may be an abnormal condition and the unit may need service. Call
