WELCOME
To the comfortable world of humidified air. When you use your Honeywell humidifier,
notice that your skin is not as dry, and that your scratchy throat and irritated nasal
passages that aggravate allergies and asthma are steadily improving.
You have also taken the first step in reducing the zapping you create when you walk on
your carpet and then touch your TV, computer, metal door knob or your pet. Your
furniture and woodwork are also benefitting from the difference that humidified air
makes.
Congratulations! You have just made a great investment in improving the comfort of
your home.

Determining Best Location for Humidifier
CAUTION
Temperature and Static Pressure Hazard.
Can cause property or equipment damage.
Locate humidifier where ambient temperature is between 32°F (0°C) and
160°F (71°C).
Do not install humidifier 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 124 psi.
• Select a location for the humidifier on the supply (warm air stream) plenum. See
Fig. 1.
• Select a location that cannot damage the air conditioner A-coil during installation.
• Do not locate the humidifier on the furnace body.
• Allow adequate clearance in front of and above the humidifier so you can easily
remove the cover to perform routine maintenance.
— Mount the humidifier at least 3 in. (78 mm) above the furnace body to allow
adequate space for the solenoid valve and drain line.
— Mount the humidifier in a conditioned space to prevent freezing.

Fig. 1. Typical humidifier installation locations.
Selecting Water Supply Location
• Use either hard or soft water in the humidifier and either hot or cold water. The
water flow rate, with the humidifier running, is 3.5 gal/hr (13 liters/hr) to flush the
pad and provide moisture for evaporation.
• Make sure that the 20 ft (6.2m) of feed water tubing provided is adequate to
connect the water supply (saddle valve) with the humidifier solenoid valve.
Locating Closest Floor Drain
• Select location with access to a floor drain to provide drainage for air conditioner
condensation and humidifier drainage.
• If you do not have a drain available, we recommend that you install the Honeywell
Whole House Drum or Disk Humidifier. Make sure that the 10 ft (3.1m) of drain
tubing is adequate to reach from the humidifier drain connection to the floor drain.
Selecting Location for Humidistat
• Select a location for the humidistat on the return plenum or on the wall in the living
space.
— Mounting on the return plenum is the easiest installation for the control wiring
circuit.
For return duct mounting, the humidistat should be mounted upstream from the
humidifier or bypass so that it is properly sensing the relative humidity of the living
space. Locate the control at least 8 in. (203 mm) upstream from the humidifier in the
return air duct. (See Fig 2.)

Locating Closest 120V Electrical Outlet
• Select location with access to an outlet. If not available, contact an electrician to
have one installed.
• Make sure that the humidifier cord is adequate to reach from the humidifier to the
outlet.
• Make sure that the 20 ft (6.2m) of thermostat wire is adequate to reach from the
humidifier solenoid, to the pressure switch, to the humidistat.

Chemical Hazard.
Can cause personal injury or equipment damage.
Do not use any line connected to an air conditioner.
Do not use gas line.
2. Use the self-piercing saddle valve (included) to tap into the water supply line at
the location selected. See Fig. 6. If tapping into galvanized pipe, drain line and
pre-drill 3/17 in. tap for saddle valve.
NOTE: The saddle valve is not designed to regulate water flow. The valve is either
open or closed.
IMPORTANT
To prevent debris from clogging the solenoid in-line filter, be sure to install the
saddle valve handle pointing toward the ceiling.

4. Cut a 3/4-in. diameter hole in the
duct within 10 feet of the switch to
ensure the provided tubing reaches
the pressure tap elbow.
5. Insert the black rubber gasket into
the duct hole.
6. Connect the tubing to the tubing fit-
ting elbow and insert the tubing fit-
ting elbow into the black rubber
gasket.

TESTING HUMIDIFIER OPERATION
Checklist
Humidifier is level.
Control wiring was reviewed using circuit diagram.
Humidifier is plugged in.
Feed line has no kinks.
Drain line slopes continuously down and ends at floor drain.
Water hose inside humidifier is connected to PerfectFlow™ water distribution tray.
After installation use the following steps to check the humidifier operation:
1. Turn on the power and the water supply
2. Turn the H8908 Humidistat to On and turn on the heat by setting the thermostat
to 10ºF (6ºC) above room temperature.
IMPORTANT
The furnace blower must be on to activate the humidifier.
3. Make sure that water is flowing out of the drain hose. If water does not flow, see
Troubleshooting Your Humidifier section.
4. Check for leaks.
5. Reset the thermostat and H8908 Humidistat to a comfortable setting for auto-
matic operation.
OPERATION
How Your Humidifier Works
Your Honeywell humidifier uses 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.
Your humidity control monitors the relative humidity and activates the humidifier
accordingly. The humidifier has a water supply that dispenses water evenly over a
humidifier pad. The warm dry air, from the furnace, passes over the humidifier pad and
picks up the moist air to circulate it throughout your home.
Humidified air feels warmer and more comfortable so you may be able to lower your
thermostat heating setpoint, which saves money on your heating fuel bills. The end
result is that your humidifier gives you a comfortable environment that is also energy
efficient.

HE360 HUMIDIFIER AND INSTALLATION KIT
15 69-2629EF—01
Controlling Your Humidity Settings
Your H8908 Humidistat controls your humidifier.
• Choose the humidity control setting using the combination of relative humidity/
outdoor temperature setting scale on your humidity control dial.
• Match the dial setting to the outdoor temperature to optimize the humidity level
while reducing the moisture condensation on your windows. See Table 2 to adjust
the humidity control to the recommended setting.
NOTE: As the outside temperature drops, a lower humidity setting is recommended
to accommodate dewpoint effects. These settings should reduce the accumu-
lation of moisture and ice on windows and other areas of the home.
• Adjust the humidity control setting to adjust for indoor activities such as cooking,
showering and clothes drying, which can cause excessive levels of humidity that
can accumulate moisture on your windows.
NOTE: If these activities persist 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.

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 Honeywell humidifier.
WARNING
Serious Personal Injury Hazard.
Can cause electrical shock and injury from moving parts.
Disconnect power and shut off water supply before removing cover.
IMPORTANT
Never oil any part of the humidifier.
Every 1 to 3 Months (Depending on Water Quality)
1. Disconnect the power and turn off the humidifier water supply.
2. Remove the humidifier cover by unplugging the connector and loosening the
thumb screw. Grasp the cover near the bottom and pull toward you. See Fig. 14.
3. Remove the humidifier pad assembly from the humidifier by grasping the top of
the tray and pulling it toward you.
4. Lift the tray off the pad.
5. Gently pinch the water nozzle catches inward until you can lift the water nozzle
off the tray.
6. Carefully remove any mineral deposits from the tray and frame. Be sure the
frame drain hole has nothing blocking it.

Humidifier for Correct Operation section.
CHECKING YOUR HUMIDIFIER FOR
CORRECT OPERATION
After winter startup or servicing, use the following steps to check your humidifier
operation:
1. Turn on the humidifier power and water supply.
2. Turn the humidistat to its highest setting and set the thermostat to 10°F (6°C)
above the room temperature.
3. Observe that water is flowing out of the drain hose.
NOTE: The furnace blower must be running to activate the humidifier.
4. Reset the thermostat and humidistat to a comfortable setting for automatic oper-
ation.
