NOTES ON LOCATION:
In order to get the most effective use from your humidifier, it is important to position
the unit where the most humidity is needed or where the moist air will be circulated
throughout the house such as near a cold air return. If the unit is positioned close to
a window, condensation may form on the window pane. If this occurs the unit should
be repositioned in another location.
Place humidifier on a flat level surface. Do NOT position
the unit directly in front of a hot air duct or radiator. Do
NOT place on soft carpet. Due to release of cool, moist
air from the humidifier, it is best to direct air away from
thermostat and hot air registers. Position humidifier next to
an inside wall on a level surface at least 2 inches away
from the wall or curtains.
Be sure that the humidistat, which is located on the
power cord, is free from obstruction and away from any
hot air source.
ABOUT HUMIDITY
Where you set your desired humidity levels depends on your personal comfort
level, the outside temperature and the inside temperature.
NOTE
: Recent CDC tests show that only 14% of flu virus particles could infect
people after 15 minutes at levels of 43% humidity.
You may wish to purchase a hygrometer to measure the humidity level in your
home. The following is a chart of recommended humidity settings.

NOTE:
External hygrometer readings and humidistat readings may differ.
Humidity levels can vary significantly even in one room.
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. We recommend
room humidity levels do not
exceed 50%.
