Operating Instructions

CCWB3-17K & CCWP3-18)
Your new Complete Comfort
™
Humidifier is controlled by a manual
humidifier control installed either in the living area or in the cold air
return. It is important to anticipate a drop in temperature and reduce
the setting accordingly to avoid excessive condensation. For
example, with an outside temperature of 20° the correct setting will
be 35% relative humidity. If the temperature is expected to fall to 0°
that evening, then reduce the setting to 25% several hours prior to
the temperature change.
Observance
of
the
recommended relative
humidity level on your
humidifier control (see
table) is an important
safeguard.
Conden-
sation of water on
inside windows in the
form of fogging or
frost is usually an indi-
cation of excessive relative humidity. The same condensation can
take place in other areas in your home with the possibility of result-
ing damage.
Be sure to keep fireplace dampers closed when not in use. They pro-
vide an excellent escape route for heat, as well as humidity.
The humidifier control can be used to determine the relative humid-
ity in your home during the winter. Turn the dial to the lower setting
then reverse the dial direction slowly until a “click” is heard. At this
point, read the relative humidity on the dial. This will be very close to
the actual relative humidity in your home.
To check the humidifier operation, set the humidifier control above
the click point, make sure that the water saddle valve is open and
that there is electricity to the humidifier. The furnace blower motor
must be operating for the humidifier to function. After the humidifier
has operated for several minutes and water is entering the humidifi-
er and coming out at the drain, reduce the humidifier control setting
below the click point and the humidifier should automatically shut
off. Now, set the humidifier control dial at the recommended inside
relative humidity, depending on the outside temperature. Follow the
suggested settings prior to a drop in the outside temperature.
Automatic Humidifier Controls
(
Humidifier Models CCWB3-12A, CCWB3-12AK, CCWB3-17A,
CCWB3-17AK & CCWP3-18A)
CCWB3-12A, CCWB3-12AK, CCWB3-17A, CCWB3-17AK and
CCWB3-18A humidifiers are controlled by an automatic humidifier
control, which offers two modes of operation: automatic and manual.
When installed in the automatic mode, the system benefits you in the
following ways:
1. The control automatically adjusts your home’s RH based on the
outdoor temperature.
2. The control eliminates the need to manually adjust the control.
3. The automatic humidifier control precisely controls the RH in your
home, ensuring maximum comfort for a greater percentage of
time. The automatic humidifier control also prevents excess con-
densation or low humidity in the home.
4. The automatic humidifier control also eliminates the need to turn
the dial setting to
OFF
during the summer season.
Operating Instructions – Automatic Mode
Immediately after installation, the automatic humidifier control must
be set to match your home’s condition. Follow these steps to adjust
the automatic humidifier control. See
Figure A
.
1. Turn the knob to setting 5, which is within the normal range.
During the next 24 to 48 hours, it may be necessary to adjust the
dial for more or less humidity, depending on your personal comfort
and home’s requirements. See Table 1.
