Tools Required:

• Tin snip
• Screwdriver
• Pliers
• Adjustable or open-end wrench

• Level
• 3/4 in. (19 mm) sheet metal drill bit 

Installation

1. Turn off power to the air handling system at the circuit breaker.
2. Draw a level line on the plenum in the selected location.
   IMPORTANT
   Be sure the mounting template is level before marking. Use of a small level is recommended.
3. Tape the correct template in position and trace around the template.
4. Remove the template and carefully cut the opening with tin snips.
5. Disassemble the humidifier; remove the cover and take out the humidifier pad assembly.
6. Make sure the humidifier housing is level, then position it in the opening so the plastic tabs are in place on the lower sheet metal edge of the opening. Use pliers, as necessary, to flatten cut edges.
7. Secure the humidifier housing to the opening at the top and bottom using sheet metal screws.
8. Reassemble humidifier side plates to customize the orientation for your specific install. The side plate with the humidifier port needs to be on the side of the humidifier that is closest to the bypass ducting. Be sure to open the bypass flap for use and close it when the humidifier is not used.
9. Slide bypass duct over the humidifier port on the HE105/HE205, making sure that the flex duct advances past the raised plastic tabs on the port. These tabs will help to hold the flex duct in place. Verify that the damper blade has adequate clearance to move back and forth between the closed and open positions. Secure the flex duct in place with the plastic connector strap.
10. Seal the duct connections with foil tape. Seal both 1) the connection between the starter collar end of the flex duct and the home’s duct work and 2) the end of the flex duct to the humidifier over the top of the connector strap.
11. Reinstall the humidifier pad assembly in the humidifier housing.
12. Hinge the cover in place and secure with the thumbscrew located at the bottom of the cover.
13. Turn off water supply and tap into a water line.
14. Use 1/4 in. O.D. copper tubing and connect to inlet side of solenoid valve via a compression fitting or Resideo Quick Connect fitting.
15. Connect a 1/2 in. (13 mm) drain tube to the humidifier drain fitting and run to a suitable drain.

Wiring 

Fig. 1. Wiring H6062 to humidifier with Fan Interlock 

Fig. 2. Wiring HumidiPRO in line with air proving device.  Fig. 3. Wiring HumidiPRO with 2-speed fan motor.*

Fig. 4. Wiring HumidiPRO with current-sensing relay.

* When a thermostat with IAQ control is used instead of a humidistat, it simplifies the wiring circuit. The thermostat U contacts are installed in place of the H6062 from Fig. 3 and the sail switch is removed from the circuit. No special wiring of the transformer primary, sail switch, or relay is needed.

CHECKOUT

• Humidifier is level.
• Control wiring was reviewed using circuit diagram.
• Feed line has no kinks.
• Drain line slopes continuously down and ends at floor drain.
• Water hose inside humidifier is connected to PerfectFLO™ water distribution tray.
