Your humidifier is equipped with a convenient
front pour- in door. Use a pitcher to fill the unit
through the pour-in door.
When the door is opened an LED light
illuminates the MAX FILL line inside. Fill the unit
until the small white float reaches the
MAX FILL line. The reservoir holds 3.5 gallons.
Do Not Overfill.
NOTE: Fill unit with cool, fresh (preferably unsoftened) water. If you only have
softened water available in your home, you can use it,
but mineral buildup will occur more quickly.
NOTE: On initial fill up, it may take approximately 20 minutes for the wicks to
become fully saturated.
CAUTION: Use only EPA Registered Bacteriostat.
Under no circumstances should
you use Water Treatment products intended for Rotobelt or Ultrasonic
humidifiers.
NOTE: We recommend using AIRCARE
®
or Essick Air
®
Bacteriostat Treatment P/N
1970 when you refill the water reservoir to eliminate bacterial growth. Add
bacteriostat according to the instructions on the bottle.
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 the chances of flu transmission are greatly
reduced 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.
