HE420A,B and HE460A,B

Steam Power Humidifiers

APPLICATION

The HE420A,B and HE460A,B Steam Power Humidifiers use a thermal fan interlock control to provide humidification for the whole house. The steam power humidifier is designed to work with high efficiency furnaces, heat pumps and set back thermostats. The humidifiers work with virtually any Honeywell humidity control, but use the Honeywell Perfect Climate Comfort Center™ control for optimal performance.

HUMIDIFICATEUR

HE420A,B AND HE460A,B STEAM POWER HUMIDIFIERS

IMPORTANT

Read all the installation instructions before installing the humidifier.

Select Location and Mount

There are three typical ways of mounting the steam humidifier:

• horizontally under at least a 10 in. (254 mm) wide duct using the mounting bracket (preferred mounting);

• horizontally under a reinforced duct;

• horizontally under a duct extension using the mounting bracket.

Decide which mounting is appropriate and follow those mounting instructions. See Fig. 2 through 4.

Select a location where the humidifier can be plugged in without an extension cord. The preferred installation location is on the warm air side of the furnace. If that location is not possible, mount the humidifier a minimum of 6 ft (1.8m) upstream from the furnace filter. Depending on the location selected, additional duct reinforcement may be necessary because the humidifier weighs 18 lb when filled with water.

WARNING

Electrocution, Heavy Equipment and Chemical Hazard. Can cause death, blindness, water damage to home and heater failure.

• Do not cut into any air conditioning or electrical line.

• Mount the humidifier in a level position to avoid water damage and heater failure.

• Wear safety glasses when cutting or drilling.

• Reinforce duct as necessary to ensure stability.

CAUTION

Steam Condensation, Fire and Freezing Water Hazard. Can cause failure of fan or limit control or result in water damage to home.

• Do not install the humidifier where the sidewalls of the return air duct are constructed of wood (i.e., floor joist).

• Do not install the humidifier where the temperature is lower than 32°F (0°C) or higher than 200°F (93°C).

Mount Horizontally Using Mounting Bracket (Preferred Mounting Method)

IMPORTANT

The duct must be at least 10 in. (254 mm) wide to use this mounting method.

The duct is the strongest when using the bracket mounting method because the least amount of duct reinforcement is required because of the bracket location. However, reinforcement may still be necessary to help support the weight of the humidifier and keep it level.

1. Tape the template 1/2 in. (13 mm) from the edge of the duct and trace around the template. See Fig. 5.

2. Drill a 3/8 in. (10 mm) hole within the center portion of the template.

3. Use tin snips to cut around the outline of the template.

IMPORTANT

Follow the dotted line carefully.

4. Remove the template and sheet metal.

5. Cut two 8 in. (203 mm) pieces of the S-cleat

(provided).

6. Place the S-cleat pieces on the narrow sides of the rectangular opening so the opening (slot) protrudes down and out of the duct.

7. Cut a 10-1/2 in. (267 mm) piece of S-cleat.
