Select a location for the Humidistat.
•

Humidistat can be mounted on the return duct or on 
the wall in the main living space. (Return duct 
mounting is easiest for installing wiring.)

•

For return duct mounting, the Humidistat must be 
mounted upstream from the Humidifier and Bypass 
Collar so it is properly sensing the relative humidity 
of the house. See Fig. 3.

•

Locate the control at least 8 in. upstream from the 
Humidifier or Bypass Collar in the return air duct.

Select a water supply location
•

Use either hard or soft water in the Humidifier.

•

Use either hot or cold water in the Humidifier.

•

Make sure 20 ft. of Plastic Water Tubing is long 
enough to connect the water supply (saddle valve) to 
the Humidifier.

•

Make sure saddle valve is accessible after 
installation.

Locate 120V Electrical Outlet.
•

Select a location with access to an outlet. If an outlet 
is not available, contact an electrician to have one 
installed.

•

Make sure the 20 ft. of Thermostat Wire is adequate 
to reach from the Humidifier motor to the Humidistat, 
and the Humidistat to the Plug-in Transformer.

Locate Closest Floor Drain.
•

Select location with access to floor drain, if available.

•

Overflow drain is required in applications where 
water overflow could cause flooding or property 
damage. 

•

If an overflow drain is needed, make sure Overflow 
Tubing is long enough to reach from the Humidifier to 
the floor drain.

NOTE:

Every installation is unique. Please ensure that 
water, power, and drain are available before install-
ing the device. In some cases, additional wire, tub-
ing, or duct may need to be purchased in order to 
correctly install the Humidifier.

Turn off power to heating and cooling system.

Draw a level line on the duct in the location chosen for 
the Humidifier. (Leveling assures optimal performance.) 
See Fig. 4.

NOTE:

There must be at least 1-1/2 in. of duct above the line 
and 8-1/2 in. of duct below the line for proper installa-
tion. The duct must also be at least 11 in. wide for 
proper installation.
