Filter Replacement and Care
WARNING:
To reduce the risk of
shock or injury from moving parts,
always unplug humidifier before
removing or replacing any parts.
CAUTION:
To help retard bacteria
growth and keep maximum
efficiency, the filter should be
replaced at least once per season,
or more often under hard water
conditions. Use MAF2 replacement
filter.
Replace the evaporative wicking filter
at least once per humidification season
or more depending on water conditions
in your area.
Filter Replacement
1. Unplug humidifier. Before removing
the filter, move the humidifier to an
area not susceptible to water damage.
(i.e. kitchen or bath areas).
2. Remove the water bottle and set
aside. Be sure not to bump or damage
the fill valve.
3. The upper housing and the base are
held together by two hooks at the front
of the housing and a flexible snap in
the rear. To remove the housing, press
in on the triangular shaped snap at the
rear of the humidifier, below the cord
exit, while lifting upward, tilting the
upper housing forward to clear the
hooks at the front of the base.
4. Set the upper housing aside.
The filter is now accessible.
5. Take note of the filter position.
Remove the filter. You may want
to clean the base at this time. See
the “Cleaning and Maintenance”
section of this manual.
6. Install a new filter (MAF2) into
the base. Position the filter
between the uprights in the bottom
of the base. The filter should be
resting on the floor of the base.
7. Return the upper housing to the
base by first placing the hooks
located near the front of the base
into the mating holes in the upper
housing. Then tilt the upper
housing down towards the base
until the rear snap engages the
main housing.
8. Reposition the humidifier to its
operating position.
9. The humidifier is now ready to
be filled for operation.

Step 4. Setting the Controls
Where you set your desired
humidity levels depends on
your personal comfort level,
outside temperature and
inside temperature. A
starting Set point of 30%-
40% ROOM humidity is
recommended but there may
be conditions that require a
different setting.
The chart provided offers general guidelines for selecting indoor humidity.
IMPORTANT:
Water damage may result if condensation starts to form
on windows or walls. Humidity SET point should be lowered until
condensation no longer forms. We recommend room humidity levels
do not exceed 50%.
Operating the Controls
Digital Display
Press the power button once to turn
the unit on
*
. Initially there is a slight
delay while the electronics calibrate.
Two bars (--) appear during this time.
Once calibration is complete a ROOM
humidity reading between 20% – 95%
will be displayed. A flashing 20 display
indicates that the room humidity is less
than 20%.
NOTE
: The default settings at initial
startup are
(LOW)
F1 fan speed and
65% SET
humidity. After desired settings
are selected by the user, they remain as
long as the unit remains plugged in and
there is no power interruption. If the unit
is unplugged the
original
default settings
will be restored.

Humidifier fan should operate at
initial startup. If it does not, refer
to “Fan not operating (digital
display is illuminated)” in the
“Troubleshooting” section on
