WIRING THE HUMIDIFIER
CAUTION
Hazardous Voltage.
Can cause personal injury or equipment damage.
• Disconnect the power supply before installing or
servicing.
• On multispeed blower applications, do not wire the
high voltage side of the transformer to the same
power source that services the furnace blower.
Premature transformer burnout may occur.
All wiring must comply with applicable local codes, ordinances
and regulations.
1. Mount the transformer in a convenient location.
2. Connect wires to the 120V side of the transformer.
3. Wire the humidifier solenoid valve, current sensing
relay, or sail switch, humidity control and transformer.
Refer to the humidity control installation instructions for
mounting and wiring information.
NOTE: Select models of fan centers include humidifier taps
so the current sensing relay or sail switch is not
needed.

PLUMBING THE SADDLE VALVE
Hot or cold water, either hard or softened, can be used in the
humidifier.
1. Use the self-piercing saddle valve (included) to tap into
the water supply line at an appropriate location.
IMPORTANT
• The saddle valve is not designed to regulate water
flow. The valve is either open or closed.
• To prevent debris from clogging the solenoid inline
filter, be sure to install the saddle valve handle point-
ing toward the ceiling.
NOTE: Lightly clean the copper tubing ends with fine sand-
paper before making any connections.
2. Use 1/4 in. O.D. copper tubing and connect the saddle
valve to the inlet side of the solenoid valve.
CAUTION
Hazardous Voltage.
Can cause personal injury or equipment damage.
Do not use any line connected to an air conditioner.
a. Place the brass compression nut over the copper
tubing.
NOTE: Do not over tighten the compression nut. Moderate
tightness prevents leaking.
b. Slide the brass ferrule over the tubing.
c. Insert the tubing into the solenoid valve fitting and
support the valve while tightening the compression
nut.
3. Connect a 1/2 in. (13 mm) drain tube to the humidifier
drain fitting and run to a suitable drain.
NOTE: Slope the drain tube downward for correct drainage.
CHECKING THE INSTALLATION
Use the following procedure to check out the humidifier
installation:
1. Open the saddle valve.
2. Set the thermostat setpoint to 10°F (6°C) above the
room temperature.
NOTE: The furnace blower must be on for the humidifier to
operate.
3. Set the Convertible Humidity Control to a high setting.
4. Observe the water running out of the drain line to be
sure the humidifier is working.
5. Check for leaks.
6. Reset the thermostat and Convertible Humidity Control
to a comfortable setting.
OPERATING THE HUMIDIFIER
The HE220A and HE260A Humidifiers are controlled by the
H8908B Humidistat that is installed either on an interior wall in
the living area or in the equipment room. Choose the humidity
control setting using the combination relative humidity/outdoor
temperature setting scale on the humidistat dial. Match the
dial setting to the outdoor temperature for optimizing the
humidity level while reducing the moisture condensation on
inside windows. Use Table 5 to adjust the humidistat to the
recommended setting.
NOTE: As the outside temperature drops, the recommended
setting is lowered to accommodate the effects of
dewpoint. These settings should reduce the accumu-
lation of moisture and ice on the windows and in
other areas of the house.
Some indoor activities such as cooking, showering and
clothes drying can cause excessive levels of humidity and
start the accumulation of moisture on the windows.
NOTE: If this condition persists for more than a few hours,
set the humidity control to the lowest setting to turn
off the humidifier. If the condition does not improve,
ventilate your home to remove the moisture.
Table 5. Recommended Humidistat Settings.
OPERATION
The HE220A and HE260A Humidifiers use the principle that
vapor (evaporated water) is created when warm air blows
over a water soaked area. As the vapor circulates, the relative
humidity rises.
The humidity control monitors the relative humidity and
activates the humidifier accordingly. The humidifier has a
water supply that disburses water over a humidifier pad. The

warm dry air from the furnace passes over the humidifier pad
and collects moisture and them circulates it through the
house.
Humidified air feels warmer and more comfortable so the
homeowner may be able to lower the thermostat heating
setpoint and save money on heating fuel bills. The end result
is that the humidifier gives the homeowner a comfortable
environment that is also energy efficient.
MAINTENANCE
A regular maintenance program prolongs the life of the
humidifier and provides a more comfortable environment.
