— 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.
Make sure that the 20 ft (6.2m) of feedwater tubing provided is adequate to connect the water supply (saddle valve) with the humidifier solenoid valve.
Locating Closest Floor Drain
Select a 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 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 120V Electrical Outlet
Select a 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 (6.2m) of thermostat wire is adequate to reach from the humidifier solenoid to the sail switch, to the humidistat.
