Essick Air 447 301 Humidifier User Manual


 
HUMIDITY SETTING
20) If the room humidity is lower than the Set Humidity, the fan motor will
start and run until the room humidity exceeds the Set Humidity by +6%
R.H. If higher than the Set Humidity, the fan motor will not start. The
desired humidity level can be changed with the “Set Humidity”, (right),
button. Press the button once, and the display will flash. Repeatedly press-
ing the button will increase the Set Humidity in steps of 5% RH. When the
desired humidity level is reached, (between 30 – 90 % RH), release the
button. If the button is released and then held down while flashing, the
display will auto-advance through the range. Release the button to exit
the auto-advance mode.
BOTTLE REFILL SYSTEM
21) When one bottle empties, one red refill indicator light will light, and the
fan will continue to run. When the water bottles are both empty, the two
red refill indicator lights will be lit and the fan motor will stop.
22) After the “Set Humidity” button has been inactive for three seconds, the
control will exit the Set Mode with the last programmed number remaining
on the display.
NOTICE: Under certain conditions, cold objects in the room, such as windows
and outside walls, may cause moisture to condense. Severe condensation on
window sills and walls may result in water damage. When these conditions
exist, a lower humidistat setting is recommended.
