Using Your Humidifier
Step 1
Be sure unit is full of water and plugged in.
Step 2
Set the Speed Control to LOW ( 
).
Step 3
Set Humidity Control to a medium posi- tion (see diagram below)
NOTE: Humidifier should operate with humidity control on the recommended medium setting. If it does not, the humidi- ty is at a relatively high level. To test the unit under this condition, turn Humidity Control all the way to clockwise and unit should begin to operate. After the unit has been tested, set Humidity Control to medium or desired level.
Step 4
If humidifier stops running and the amber Refill Light is not illuminated, the humidity level is at the normal requirements for that setting or it is adjusting to the home con- ditions. The table below shows recom- mended indoor humidity levels. The figure below shows approximate relative humidi- ty percentages which correspond to the various settings of the Humidity Control.
When Outdoor Recommended Indoor Temperature is: Relative Humidity is:
20% | ||
2° F | 25% | |
10° F | 30% | |
20° F* | 35% | |
|
|
|
Allow 24 hours for humidifier to adjust.
If humidity level in home is sufficient, the humidifier will only operate with Humidity Control set on maximum.
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.
