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
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.
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%.
NOTE: External hygrometer readings and humidistat readings may differ. Humidity
levels can vary significantly even in one room. The amount of time it takes to affect the
room humidity depends on the relative humidity of the air. In especially dry areas it could
take up to 48 hours to see humidity climb to the desired level.
