HE360 Powered Flow-Through Humidifier
READ AND SAVE THESE INSTRUCTIONS
APPLICATION

for the whole house. The HE360 works with virtually any Honeywell humidity control, but use with the
Honeywell Perfect Climate Comfort Center™ control for optimal performance.
INSTALLATION
WARNING
Personal Injury or Equipment Damage Can Occur.
Do not cut or drill into any air conditioning or electrical accessory.
CAUTION
• 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 where freezing temperatures could occur.
• Be sure supply plenum static pressure is no greater than 0.4 in. W.C. and water pressure is no
greater than 125 psi or equipment damage can occur.
IMPORTANT
Be sure the template is level before marking to assure optimal product performance.
1. Determine the best location for the humidifier and draw a level line on the plenum. See Fig. 1 and 2.
IMPORTANT
Be sure the humidifier will be at least 3 in. (76 mm) above the furnace jacket or there will not be
enough room for the drain line. Check that there is enough room above the humidifier to remove
and install the humidifier cover. Do not install on a furnace jacket.

IMPORTANT
Be sure the black mark on the end of the humidifier pad is facing up for proper operation. Check
that the water feed tube is placed in the guide slots of the humidifier housing.
8. Reinstall the humidifier pad and PerfectFlo™ water tray in the humidifier housing.
9. Hook the top of the cover to the housing and secure with the thumbscrew located at the bottom of
the cover.
WIRING
WARNING
Serious Personal Injury Hazard.
Can cause electrical shock and injury from moving parts.
Disconnect power supply before installation or servicing to prevent electrical shock or equipment
damage.
This device contains a moving fan blade. Disconnect power prior to installation or servicing. Do not
operate the humidifier without the cover securely attached.
All wiring must comply with applicable local codes, ordinances and regulations.
1. Wire the humidifier solenoid valve, current sensing relay or sail switch, and humidistat. See Fig. 4, 5
and 6. Refer to humidistat installation instructions for mounting and wiring information.
IMPORTANT
If not using a current sensing relay or sail switch, the 120V humidifier plug must be energized
during blower motor cycles for proper operation.
NOTE: Select models of fan centers include humidifier taps so the current sensing relay or sail switch are
not needed.
