End of Humidification Season
• Clean the humidifier and shut it off at the end of the heating season.
• Turn the water off at the saddle valve by turning the handle to the right (clockwise)
until the water stops flowing and/or there is resistance.
• Unplug the humidifier at the wall outlet
• Turn the damper blade to the "summer" position.
IMPORTANT
Be sure the humidifier power is off.
Replacement Humidifier Pads
It is recommended to replace the humidifier pad on an annual basis. However, if
your home has hard water, the pad may need to be replaced more frequently
because of the buildup of minerals diminishing its ability to operate normally. If
there is access to a water softener, it is recommended to use softened water.
