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 sole-
noid valve and drain line.
—
Mount the humidifier in a conditioned space to prevent freezing.
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 the length of the 1/4” of feed water tubing is adequate to connect the water supply shut-off 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 Resideo Whole House Drum or Disk
Humidifier. Make sure that the 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 installation for the control wiring circuit.
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.)
