2. Disconnect the water line at the humidifier.
3. Remove the float from the humidifier (pull out
pivot pin).

replace it if both surfaces are worn, as shown in

5. Reinstall and turn on the water and test the float.
CAUTION: Do not use tablets in an attempt to control
lime deposits in this humidifier! Use of tablets may cause
the humidifier to splash causing damage to the humidifier
or furnace.
IF AIR IS TOO DRY (AND WINDOWS ARE NOT
SWEATING):
1. Wait until the furnace blower comes on. Then
rotate humidistat knob back and forth from TEST
to the OFF humidity setting, if the humidifier
goes on and off, the humidistat is operating
properly. Check for proper operation of the
humidifier.
2. If the humidifier is off when furnace blower is on,
readjust the humidistat by turning the knob so
the indicator points to the setting for the lowest
24-hour temperature predicted.
IF SWEATING OF WINDOWS OR WALLS
OCCURS:
1. Press the switch on the humidifier to the OFF
position. When moisture is no longer present, set
the humidistat indicator to the setting for the
lowest anticipated 24-hour outdoor temperature.
Switch the humidifier to the ON position.
2. If sweating reoccurs, repeat Step 1, allowing for
an additional 10“F lower setting of the outdoor
temperature than anticipated in the next 24
hours. Continue this procedure until the humidity
level is stabilized.
NOTE: Because of differences in home construction,
the number of occupants, and living habits in some
homes, when the anticipated 24-hour lowest outdoor
temperature is, for example, +10°F your ideal humidi­
stat setting may be the low position.

humidifier for the summer:
• Turn the humidistat dial counter-clockwise to the
minimum setting position.
