1. Place the humidifier where you intend
to run it and be sure it is plugged in
and full of water.
2. Press the POWER button once to turn
the humidifier on. The red power light
will illuminate.
The fan will immediately operate on
LOW
speed and the
SET
humidity percentage
will read 65 on the digital display.
NOTE:
Humidifier fan should operate at
initial start up. If it does not, refer to the
“Trouble Shooting” section on page 16 of
this manual.
3. Wait a few seconds while the humidifier
takes a
ROOM
humidity reading.
During this time two bars (- -) will flash
on the display.
4. Once a ROOM reading has registered
proceed to adjust the desired humidity
percentage by pressing the + or -
button. It will change the desired SET
humidity level in increments of 5%.
If the room reading is a flashing 25, the
humidity level is low. A
SET
point of 30% -
40% is recommended but there may be
conditions that require a different setting.
Depending on your particular environment
it could take 24 hours and in some cases
longer for the humidifier to reach your
desired humidity. It may take several
fillings to bring the
ROOM
humidity level
up to the
SET
point. A faster fan speed
will accomplish this quicker. Once estab-
lished adjust the fan speed to suit your
needs.
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.
5 If the humidifier stops running and the
red
REFILL
light is not illuminated, the
humidity level is at the normal require-
ments for that
SET
point. The table
below shows recommended indoor
humidity levels as it relates to outdoor
temperatures.
