MAINTAINING YOUR HUMIDIFIER
A regular maintenance program prolongs the life of your humidifier and makes your
home more comfortable. The frequency of cleaning depends on the condition of
your water.
You can use either hard or soft water in your humidifier, but hard water mineral
deposits are more difficult to clean than soft water deposits.
Use the following procedure to clean your humidifier.
IMPORTANT
Never oil any part of the humidifier.
Once per year, depending on water quality
(either at the beginning or the end of the humidification season)
1.
Disconnect the power by unplugging the transformer from the outlet and turn
off the humidifier’s water supply by turning the handle to the right (clockwise)
until the water stops flowing and/or there is resistance.
2. Remove the humidifier cover. See Fig. 18 on page 17.
3. Remove the humidifier pad assembly from the humidifier by grasping the top of
the tray and pulling it toward you.
4. Pull one side of the humidifier pad assembly frame toward you and remove the
tray from the frame.
5. Gently pinch the water nozzle prongs (a pair of prongs is located on each side of
the PerfectFLO
™
water distribution tray) inward until you can lift the water
nozzle off the tray.
6. Slide the humidifier pad out of the frame and discard the pad. 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.
7. Carefully remove any mineral deposits from the tray and frame. Be sure the
frame drain hole has nothing blocking it.
8. Disconnect the drain hose from the drain fitting on the bottom of the humidifier
housing.
