For best results:
1. Allow for optimum airflow by keeping the mist outlet and grill un-
obstructed. Ensure curtains and other items are far enough away
from the unit to not be pulled into the side inlets or interfere with
airflow.
2. Operate your Humidifier continuously. This will help maintain the
desired humidity level in your home, cost only pennies a day, and
will not damage the unit.
It is normal and expected for your Humidifier to run continuously
for a few days in order to raise the moisture content of the air to
the desired level upon initial use or if the air is extremely dry. When
your home and its furnishings have absorbed sufficient moisture
and become stabilized at the desired humidity level, the amount of
water used will decrease.
If you operate your Humidifier continuously, it may need to be
refilled with water every day. Simply look through the Water Tank
to be certain that there is adequate water supply for operation.
When the water level drops below the operating level, the misting
function will stop.
Any additives such as aroma fragrances or water conditioners
must not be used. Any use of such additives will void the
manufacturer’s warranty. These additives can cause cracks in the
plastic of the Humidifier and may affect Transducer performance.
Protect the Water Tank from damage. Any cracks or damage to the
Tank may cause it to leak water onto the floor or other surfaces.
If the Humidifier is turned Off, with water in the unit, and not
turned back on for 12 hours or longer, or if the unit is not cleaned
as recommended, you may experience some growth of algae or
bacteria. These microorganisms may become airborne. Thoroughly
clean the unit to eliminate any microorganisms (See CLEANING

the condensation or frost on windows. Adjust your Humidifier to a
point where this condition is at a minimum.
