HE220, HE260 HUMIDIFIER AND INSTALLATION KIT
Determining Best Location for Humidifier
CAUTION
Temperature and Static Pressure Hazard.
Can cause property or equipment damage.
Locate humidifier where ambient temperature is between 32°F (0°C) and
160°F (71°C).
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 124 psi.
• Select a location for the humidifier on the supply (warm air stream) plenum. See
Fig. 1.
• Select a location that cannot damage the air conditioner A-coil during installation.
• Do not locate the humidifier on the furnace body.
• Allow adequate clearance in front of and above the humidifier so you can easily
remove the cover to perform routine maintenance.
— Mount the humidifier at least 3 in. (78 mm) above the furnace body to allow
adequate space for the solenoid valve and drain line.
— Mount the humidifier in a conditioned space to prevent freezing.

Selecting Water Supply Location
• Use either hard or soft water in the humidifier and either hot or cold water. The
water flow rate, with the humidifier running, is 3.5 gal/hr (13 liters/hr) to flush the pad
and provide moisture for evaporation.
