The HE360A,B Powered Flow-Through Humidifier works with the 

warm air furnace blower to provide humidification for the whole 

house.

1. Read these instructions carefully. Failure to follow them could 

damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on the product to 

make sure the product is suitable for your application.

3. Installer must be a trained, experienced service technician.

4. After installation is complete, check out product operation as 

provided in these instructions.

• Do not cut or drill into any air conditioning or electrical 

accessory.

• Locate the humidifier where the ambient temperature is 

between 32°F (0°C) and 160°F (71°C) or property damage 

can occur. 

• 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 125 psi.

• Mount the humidifier at least 3 in. (76 mm) above the 

furnace jacket to allow adequate space for the drain line. 

Check that there is adequate space above the humidifier to 

remove and install the humidifier cover. Do not install on a 

furnace jacket.

1. Determine the best location for the humidifier and draw a level 

line on the plenum. See Fig. 1 and 2.

2. Tape the template in position and trace around the template. 

3. Remove the template and carefully cut the rectangular opening.

4. Loosen the thumbscrew on the bottom of the humidifier and 

remove the cover.

5. Remove the humidifier pad assembly by grasping the top of the 

tray and pulling the assembly out of the housing. See Fig. 3.

6. Position the securing clips as shown in Fig. 4.

7. Position the humidifier housing in the hole (be sure it is level), 

so the locking tabs are in place on the upper and lower sheet 

metal edge of the hole. 

8. Push in securing clips until completely seated.

9. Drill holes and install the three sheet metal screws at the top of 

the humidifier housing. Secure the housing with the three 

remaining screws.

10. Reinstall the humidifier pad assembly in the humidifier housing.

11. Hook the top of the cover to the housing and secure with the 

thumbscrew located at the bottom of the cover.

• Disconnect power supply before installation or servicing.

• This device contains a moving fan blade; do not operate the 

humidifier without the cover securely attached.

All wiring must comply with applicable local codes, ordinances and 

regulations.

• Select models of fan centers include humidifier taps so the 

current sensing relay or sail switch is not needed.

•  If not using a current sensing relay or sail switch, the 120V 

humidifier plug must be energized during blower motor 

cycles for proper operation.

1. Wire the current sensing relay or sail switch.

2. Connect only the two yellow wires to the humidistat (red wire 

connections are not used for mechanical humidistats). See the 

typical wiring diagrams in Fig. 5 through 7.

For additional mounting and wiring information, refer to the humidistat 

installation instructions.
