INSTALLATION INSTRUCTIONS/OWNER’S GUIDE
Required Accessories (Included)
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 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.)

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 automatic 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.
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 accumulation 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. See Fig. 16.
3.Remove the humidifier pad assembly from the humidifier by grasping the top of the tray and pulling it toward you.
4.Pull one side of the humidifier pad assembly frame toward you and remove the tray from the frame.
5.Gently pinch the water nozzle catches inward until you can lift the water nozzle off the tray.
6.Slide the humidifier pad out of the frame.
7.Carefully remove any mineral deposits from the tray and frame. Be sure the frame drain hole has nothing blocking it.
8.Disconnect the drain hose from the drain fitting on the bottom of the humidifier housing.
End of Humidification Season
•Clean the humidifier and shut it off at the end of the heating season.
•Use Every 1 to 3 Months section steps to shut down for the season.
IMPORTANT
Be sure the humidifier power is off.
Vacation
•When leaving on vacation, turn off the humidifier water supply and your humidistat.
•When you return, turn on the humidifier water supply and reset your humidistat.
