Position the water bottle back into the
humidifier base to the right of the grille.
The “Side Fill Cap” must be facing
outward. When positioned properly, the
plunger will open and water will flow into
the base. The base will hold the entire
contents of the water bottle. Allow up to
one minute for the water to flow into the
base. Once the bottle is empty, remove it
and refill it as mentioned earlier. Return it
to the right side of the grille. The humidifi-
er is now filled to capacity.
The water bottle may be filled at anytime
as necessary during operation. To benefit
from less frequent filling let the humidifier
exhaust both the water from the bottle
and base before filling.
The unit is now ready for operation.
The operating controls of your MoistAir
whole house humidifier are located
towards the front of the humidifier.
Familiarize yourself with the controls.
Refer to the diagram of the control area
for the correct nomenclature used in this
manual.
To Operate the Controls
Power Light
When the unit is plugged in and turned
on, the red power light will come on. It
will stay on until the unit is turned off ( )
or unplugged.
Humidity Control:
Adjust the amount of
humidity depending on your needs. The
humidifier will turn on and off as required
to maintain level of humidity selected. A
medium setting (half way between the
controls rotation) is recommended, but
there are times when low or high amount
of humidity may be preferred. For con-
stant operation of humidifier, rotating the
control all the way clockwise allows for
the maximum amount of humidity to be
evaporated into the air continuously.
IMPORTANT: Water damage may result
if condensation starts to form on win-
dows or walls. Humidity Control setting
should be lowered until condensation
no longer forms.
Speed Control
This humidifier has a three speed fan con-
trol switch. ( ) - Low, ( ) - Medium and
( ) - High). The maximum humidity output
is obtained with the fan control on
high ( ).
The higher the air flow speed, the more
water is evaporated and released into the
air. Low speed ( ) is the quietest and is
also provided for conditions that may not
require as high an evaporation rate.
Refill Light
When the unit has a small amount of
water left in it, the amber refill light will
come on and the unit will automatically
shut off.
