8) We recommend using Bemis by Essick Air
Bacteria treatment whenever you refill the
water bottles to eliminate bacterial growth.
Add bacteriostat according to the instructions on the bot-
tle and then tighten the valve caps on your water bottles.
9) Place water bottles into the humidifier with the valve cap
end down and to the back of the humidifier so that the
valve cap enters the water channel, aligning with the
“post” in the cabinet.
10) Place the end covers over the water bottles.
11) Plug cordset into interlock receptacle on back of unit.
12) Plug cordset into wall receptacle. Humidifier is now ready
for use.
CONTROLS (Models 497 800, 497 300, 496 800,
447 401, 447 301, 427 300)
FAN SPEED
13) Open control panel door by lifting with your finger under
the finger tab. Depending on which model you have, you
will have a choice of two, three, four or variable fan
speeds allowing you to use a low setting for the most
quiet operation or a high setting for maximum output.
HUMIDITY SETTING
14) All models have an automatic humidistat. The humidistat
will turn the humidifier on when the relative humidity in
your home is below the humidistat setting and will turn
the humidifier off when the relative humidity reaches the
humidistat setting. For initial operation set the humidistat
in the "comfort zone" and adjust up or down from there
to achieve the desired humidity level. Turning the varia-
blespeed humidistat all the way counterclockwise will
turn the unit off regardless of the relative humidity. This
must be turned on again before the unit will work.
REFILL LIGHTS
15) The “Refill Bottles” indicator will light, and the motor
will turn off when the bottles are empty. The right bottle
will empty first, then the left bottle. If the “Refill Light”
comes on, and the right bottle has not emptied, raise
the right side of the unit until it is level.
