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.
APPLICATION
This kit contains your new Honeywell HE360 Humidifier, H8908 Humidistat and all the
accessories required for installation.
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.

• 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.
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 Sail Switch
• Select a location for the sail switch in the cold air return duct where the sail is in the
direct path of an unrestricted air stream.
— Sail switch detects when furnace fan is operating.
• Select a location where the air duct is at least 12 in. (305 mm) deep and 8 in. (203
mm) wide to allow operation of the sail without affecting the smooth flow of air in the
duct.
— Airflow at the location can be vertical (up or down) or horizontal.
IMPORTANT
Mounting the S688 in warm air supply duct can reduce the sail life.
• Mount the switch at least 6 in. (152 mm) upstream from an elbow or junction, and at
least 15 in.
(381 mm) downstream from an elbow or junction.
• Locate the switch on the opposite side of the duct from the air entrance. (See Fig.
1-3 in S688 Installation Instructions.)
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.)
69-1176_A.fm Page 7 Monday, December 7, 2009 9:11 AM

Fig. 2. Selecting duct location for humidistat.
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 sail switch, to the humidistat.

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.
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.
