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.

Fig. 1. Typical humidifier installation locations.
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.
• Make sure that the 20 ft (6.2m) of feed water tubing
provided is adequate to connect the water supply
(saddle valve) with the humidifier solenoid valve.
Locating Closest Floor Drain
• Select location with access to a floor drain to provide
drainage for air conditioner condensation and
humidifier drainage.
• If you do not have a drain available, we recommend
that you install the Honeywell Whole House Drum or
Disk Humidifier. Make sure that the 10 ft (3.1m) of
drain tubing is adequate to reach from the humidifier
drain connection to the floor drain.
Selecting Location for Humidistat
• Select a location for the humidistat on the return
plenum or on the wall in the living space.
— Mounting on the return plenum is the easiest
For return duct mounting, the humidistat should be
mounted upstream from the humidifier or bypass so that it
is properly sensing the relative humidity of the living
space. Locate the control at least 8 in. (203 mm)
upstream from the humidifier in the return air duct. (See
Fig. 2.)
