CAUTION: To reduce the risk of injury,
fire or damage to humidifier, use only
cleaners specifically recommended
for humidifiers. Never use flammable,
combustible or poisonous materials
to clean your humidifier. To reduce the
risk of scalds and damage to humidifi-
er, never put hot water in humidifier.
CAUTION: Local water purity may vary
from area to area and under certain
conditions water impurities and air-
borne bacteria may promote the
growth of microorganisms in the
reservoir of a humidifier.
To retard bacteria growth that may
cause odors and be harmful to your
health, use only Emerson recom-
mended filters. We also recommend
using EPA approved bacteriostat
available at your local store. Under no
circumstances should you use water
treatment products for Roto belt or
Ultrasonic humidifiers. Clean your
humidifier regularly.
Step 1
To make cleaning easier, the water reser-
voirs should be empty and the base should
be completely dried out.
Set Humidity Control all the way clockwise
and Air Flow Control to high. Run until base
is dry.
Step 2
When unit is dry, rotate Humidity Control to
off.
Step 3
Unplug humidifier, and proceed to clean.
WARNING: If humidifier is not un-
plugged, fan could start after housing is
removed.
Step 4

Step 1 of the “Water Fill” section in this own-
ers manual, on page 4. Remove back grille

Step 5
Before removing filter, we recommend mov-
ing the humidifier to an area where floor
coverings are not susceptible to water dam-
age, i.e., kitchen or bath area. Remove the
filter from the unit, as shown on page 8,
Steps 3-4, under Filter Replacement
Instructions. Dispose of filters properly.
Remove mineral deposits from the humidifi-
er base by wiping with a clean damp cloth.
NOTE: Do not use any type of cleaner on
the filter.

the location where the old filter was posi-
tioned as shown on page 8, Steps 5-6.
Reattach grill to back of unit, as shown on
page 8, Steps 7-8. Return the humidifier to
the location wanted for use and install the
filled water reservoirs. Plug the unit into a
120 volt A.C. power outlet and set the con-
trols per the Operating Humidifier Controls
section of this manual.
