level), so the locking tabs are in place on the upper and
lower sheet metal edges of the hole.
8. Push in the 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 at the bottom of the
housing.
10. Reinstall the humidifier pad assembly in the humidifier
housing.
IMPORTANT
For proper operation, be sure the mark on the end of
the humidifier pad is facing up. Check that the water
feed tube is placed in the guide slots of 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.
WIRING HUMIDIFIER
WARNING
Serious Personal Injury or Equipment Hazard.
Moving parts can cause electrical shock and
injury.
•
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.
For H8908B Convertible Humidity Control Wiring
Connections:
IMPORTANT
• 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.
