Using Your Humidifier (continued)
Check Filter
Indicator
The ability of any humidifier to efficiently supply
humidity output relies heavily on the condition of the
filter. As the filter loads with impurities it gradually
loses its wicking capability. When this happens,
moisture output is reduced and the humidifier has to
work longer to satisfy the selected setting. This
humidifier has a check filter reminder timed to
appear after 720 hours of motor operation. When the
display shows an alternating “CF” and “room
humidity” setting at 5 second intervals it is a
reminder to check the filter condition.
NOTE: Some areas have high water mineral content
causing the need for more frequent filter changes.
Refer to “Replacement and Care of Filter” on page
11. If a build-up of deposits or severe discoloration is
evident replace the filter to restore maximum
efficiency.
NOTE: Be sure humidistat, which is located on
the power cord, is free from obstructions and is
away from any hot air source.
Humidistat
The humidistat located on the power cord senses
the percentage of humidity in the air. It causes the
humidifier to cycle on and off to maintain the
selected humidity SET point. The fan will turn on if
the “ROOM” reading falls 3% below the SET point
and will continue to run the humidifier until a
reading of 1% above the SET point is achieved.
The fan will turn off until the ROOM reading falls
3% below the SET point again.
