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 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 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.)
Locating Closest 120 V Electrical Outlet
• Select location with access to an outlet. If not available, contact an electrician to have one installed.
• Make sure that the humidifier cord is adequate to reach from the humidifier to the outlet.
• Make sure that the 20 ft (6.2 m) of thermostat wire is adequate to reach from the humidifier solenoid, to the
pressure switch, to the humidistat.
