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 1I. if a build-up of deposits or
severe discoloration is evident replace the
filter to restore maximum efficiency.

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.
\
NOTE: Be sure humidistat, which is
located on the power cord, is free from
obstructions and is away from any hot air
source.
