CAUTION
Property or Equipment Hazard.
Can cause property or equipment damage.
• Locate the humidifier where the ambient
temperature is between 32°F (0°C) and 160°F
(71°C).
• Do not install where freezing temperatures could
occur.
• Be sure supply plenum static pressure is no greater
than 0.4 in. wc and water pressure is no greater
than 125 psi.
Location and Mounting
IMPORTANT
Mount the humidifier at least 3 in. (76 mm) above the
furnace jacket to allow adequate space for the drain
line. Check that there is adequate space above the
humidifier to remove and install the humidifier cover.
Do not install on a furnace jacket.
1. Determine the best location for the humidifier and draw
a level line on the plenum. See Fig. 2 and 3.
IMPORTANT
Be sure the template is level before marking to
assure optimal product performance.
2. Tape the template in position and trace around the tem-
plate.
3. Remove the template and carefully cut the rectangular
opening.
4. Loosen the thumbscrew on the bottom of the humidifier
and remove the cover.
5. Remove the humidifier pad assembly by grasping the
top of the tray and pulling the assembly out of the
housing. See Fig. 4.
6. Position the securing clips as shown in Fig. 5. Do not
completely seat them.

7. Position the humidifier housing in the hole (be sure it is
level), so the locking tabs are in place on the upper and
lower sheet metal edges of the hole.
8. Push in the securing clips until completely seated.
9. Drill holes and install the three sheet metal screws at
the top of the humidifier housing. Secure the housing
with the three remaining screws at the bottom of the
housing.
10. Reinstall the humidifier pad assembly in the humidifier
housing.
IMPORTANT
For proper operation, be sure the mark on the end of
the humidifier pad is facing up. Check that the water
feed tube is placed in the guide slots of the humidifier
housing.
11. Hook the top of the cover to the housing and secure
with the thumbscrew located at the bottom of the cover.
WIRING HUMIDIFIER
WARNING
Serious Personal Injury or Equipment Hazard.
Moving parts can cause electrical shock and
injury.
• Disconnect power supply before installation or
servicing.
• This device contains a moving fan blade; do not
operate the humidifier without the cover securely
attached.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
H8908 Humidistat Wiring Connections
IMPORTANT
• Select models of fan centers include humidifier taps
so the current sensing relay or sail switch is not
needed.
• If not using a current sensing relay or sail switch, the
120V humidifier plug must be energized during
blower motor cycles for proper operation.
1. Wire the current sensing relay or sail switch.
2. Connect only the two yellow wires to the humidity
control (red wire connections are not used for
mechanical humidity control).
NOTE: For additional mounting and wiring information, refer
to the humidity control installation instructions.
Plumbing 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.
CAUTION
Equipment Hazard.
Improper installation can cause equipment
damage.
Do not use any line connected to an air conditioner.
IMPORTANT
• The saddle valve is not designed to regulate water
flow; the valve is either open or closed.
• Be sure to install the saddle valve handle pointing
toward the ceiling to prevent debris from clogging the
solenoid in-line filter.
NOTE: Lightly clean the copper tubing ends with fine
sandpaper 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.
a. Place the brass compression nut over the copper
tubing.
b. Slide the brass ferrule over the tubing.
NOTE: Do not over-tighten the compression nut.
Moderate tightness prevents leaking.
c. Insert tubing into the solenoid valve fitting. Support
the valve while tightening the compression nut.
3. Connect a 1/2 in. hose to the humidifier drain fitting and
run it to a suitable drain.
NOTE: Slope the hose downward for correct drainage.
CHECKING INSTALLATION
1. Open the saddle valve.
NOTE: The furnace blower must be operating for the
humidifier to work.
2. Set the thermostat setpoint 10°F (12°C) above the room
temperature.
3. Set the humidity control to a high humidity setting, or
place the humidity control in the test position.
4. Observe the water running out of the drain line to be
sure the humidifier is working correctly.
5. Check for leaks.
6. Reset the thermostat and humidity control to
comfortable settings.
OPERATING HUMIDIFIER
The Total Comfort System HE360A Humidifier is controlled by
the H8908 Humidistat. The humidistat is installed either on an
interior wall in the living area, or on the return air duct. Choose
the humidity control setting using the combination relative
humidity/outdoor temperature setting scale on the humidity
control dial. Match the dial setting to the outdoor temperature
for optimizing the humidity level to reduce the moisture
condensation on your windows. Table 1 can also be used to
adjust the humidity control to the recommended setting.
NOTE: As outside temperature drops, the recommended
humidity control setting is lowered to accommodate
the effects of dewpoint. These settings should
reduce the accumulation 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. If this
condition persists for more than a few hours, set the
humidistat to the lowest setting to turn off the humidifier. If the
condition does not improve, ventilate the house to remove the
moisture.
OPERATION
The HE360A Humidifiers use the principle that vapor
(evaporated water) is created when warm dry 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,
collects moisture, and circulates it through the house.
Since humidified air feels warmer and more comfortable, the
homeowner may decide to lower the thermostat setpoint, thus
saving money on heating bills. The end result is that the
humidifier provides a more comfortable environment that is
also energy efficient.
Table 1. Recommended Humidity Control Settings.
MAINTENANCE
A regular maintenance program prolongs the life of the
humidifier and provides a more comfortable environment.
Cleaning frequency depends on water conditions.
Either hard or soft water can be used in the humidifier, but
hard water mineral deposits are more difficult to clean then
soft water deposits.
Use the following procedure to clean the humidifier.
CAUTION
Personal Injury or Equipment Hazard.
Power Supply can cause electrical shock or
equipment damage.
Disconnect power supply before performing humidifier
maintenance.
IMPORTANT
Never oil any part of the humidifier.
