APPLICATION

This kit contains your new HE105 or HE205 Humidifier, H8908 Humidistat and all the accessories required for installation.

How Your Humidifier Works

Your 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.

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.

• Make sure that the thermostat wire is adequate to reach from the humidifier to the humidistat, and also from the humidifier to the transformer. See “Wiring” on page 5 for more information.

IMPORTANT

The humidistat must be mounted upstream from the humidifier or bypass duct to ensure 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. 3.)

IMPORTANT

Be sure the mounting template is level before marking. Use of a small level is recommended.

3. Locate the template (form number 33-00210,

included in the box). For the HE105 model, cut out the template along the dotted line. For the HE205 model, use the entire sheet as a template.

4. Tape the template in position and trace around the

template.

5. Remove the template and carefully cut the

rectangular opening using tin snips.

6. Disassemble the humidifier; remove the cover and

take out the humidifier pad assembly. See Fig. 4.

Connecting the Plumbing

1. Hot or cold water, either hard or softened, can be

used in the humidifier. Cut the water line so it reaches from the humidifier to the main water supply tap.

2. Turn off water supply and tap into a water line.

• Consult local codes for proper plumbing.

• Use an approved saddle valve or a T-fitting and manual shutoff valve to tap into the water line.

• Refer to the literature included with the valve you chose and the local plumbing codes. Use proper technique for the valve.

• Connect the other end of the humidifier water line to the water valve.

• Use 1/4 in. O.D. copper tubing and connect to inlet side of solenoid valve via a compression fitting or Quick Connect fitting.

• Place brass compression nut over copper tubing.

NOTE: Do not over tighten compression nut.

• Moderate tightness prevents leaking.

• Slide the brass ferrule over the tubing.

• Insert tubing into solenoid valve fitting and support the valve while tightening the compression nut.

3. Connect a water drain line.

•Consult and follow local plumbing codes for drain pipe size and flow requirement.

•The ideal installation is directly to the main floor drain using a rubber drain hose.

a. Slide a drain clamp over the tubing. b. Push the tubing over the drain nipple on the

humidifier.

c. Route the drain hose to the floor drain. The hose

must have a continuous downward slope.

d. Direct the hose outlet into the floor drain. Secure

the hose to reduce the risk of water pooling or splashing as it drains from the humidifier. See Fig. 7.

OPERATION

Controlling Your Humidity Settings

Your H8908 Humidistat (or other humidity control) 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 on page 6

to adjust the humidity control to the recommended

setting.

NOTE: As the outside temperature drops, a lower humid-

ity 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.
