Step 2: Install Humidifier - Honeywell Home HE120 Instructions D'installation

3. 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.

4. Select a water supply location
• Use either hard or soft water in the Humidifier.

installation.
5. 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.

adequate to reach from the Humidifier motor to
the Humidistat, and the Humidistat to the Plug-in
Transformer.
6. 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
