WARNING: To reduce the risk of
injury, fire or damage to humidifier,
use only cleaners specifically rec-
ommended for humidifiers. Never
use flammable, combustible or poi-
sonous materials to clean your
humidifier. To reduce the risk of
scalds and damage to humidifier,
never put hot water in humidifier.
CAUTION: Local water purity varies
from area to area and under certain
conditions water impurities and air-
borne bacteria may promote the
growth of micro-organisms in the
reservoir of the humidifier.
To retard bacteria growth that may
cause odors and be harmful to your
health, use only Emerson HDC-2R
or HDC411 replacement filters. We
also recommend using liquid EPA-
approved bacteriostat, available at
your local retail store.
NOTE:
If it is necessary to use approved
bacteriostat, follow directions correctly.
1. To make cleaning easier, the cabinet
should be emptied. To accomplish this,
allow the humidifier to run until the
automatic shutoff turns the humidifier
“OFF”. Unplug the humidifier.
WARNING: If humidifier is not un-
plugged, fan could start after housing
is removed.
Refer to pages 9 and 10 to remove parts if
necessary.
NOTE:
Before removing the internal parts
of the humidifier cabinet, we recommend
moving the humidifier to an area where
floor coverings are not susceptible to
water damage, i.e., kitchen or bath area.
2. Remove the bottle cover and water bot-
tle. Grasp the fan assembly at the front
center and rear center, and lift it off the
cabinet. Set aside on a clean flat sur-
face.
3. Lift the filter housing assembly out of
the cabinet and set to the side.
4. Remove the filters and water level float
from the humidifier cabinet. To remove
the water level float simply pinch the
float retainer to disengage it from the
rear of the cabinet.
5. Empty any remaining water in the bot-
tom of cabinet.
6. Proceed to “Bi-Weekly Maintenance” or
“End-of-Season Maintenance”.
7. Continue as described below.
8. Install new filters in the humidifier.
Reinstall the float and float retainer into
the cabinet and install the filter housing
on top of the new filters. Position the
fan assembly on top of the cabinet and
return the humidifier to the desired
location for use.
9. Refill water bottle with fresh cool water
and replace bottle cover.
10. Plug the unit into a 120V A.C. power
outlet and set the controls per the
“Operating Humidifier Controls” section
of this manual.
