your Honeywell humidifier, you notice that your skin is not
as dry, and that your scratchy throat and irritated nasal
passages that aggravate allergies and asthma are
steadily improving.

You have also taken the first step in reducing the
you create when you walk on your carpet and then touch
your TV, computer, metal door knob or your pet. Your
furniture and woodwork are also benefitting from the
difference that humidified air makes.

Congratulations! You have just made a great investment
in improving the comfort of your home.

This installation kit contains all the parts necessary to
install your new Honeywell HE220 or HE260 Humidifier.

INSTALLING HUMIDIFIER

• Select a location for the humidifier on the supply
(warm air stream) or the return plenum. See Fig. 1.

• Select a location for the bypass on the opposite
plenum. The sidewalls of the humidifier are
interchangeable to allow bypass duct mounting on
either side of the humidifier.

• Select a location that cannot damage the air
conditioner A-coil during installation.

• Select a location where the 6 ft (1.86m) of 6 in. (155
mm) duct provided is adequate to connect the
humidifier to the bypass.
— Do not locate the humidifier or bypass on a fur-

nace body.

— Allow adequate clearance in front of and above

the humidifier so you can easily remove the cover
to perform routine maintenance.

— Mount humidifier at least 3 in. (78 mm) above the

furnace body to allow adequate space for the
solenoid valve and drain line.

— Mount humidifier in a conditioned space to pre-

vent freezing.

Fig. 1. Typical humidifier installation locations.

• Select a location for the sail switch in the cold air
return duct where the sail is in the direct path of an
unrestricted air stream.
— Sail switch detects when furnace fan is operating.

• Select a location where the air duct is at least 12 in.
(305 mm) deep and 8 in. (203 mm) wide to allow
operation of the sail without affecting the smooth flow
of air in the duct.
— Airflow at the location can be vertical (up or

down) or horizontal.

IMPORTANT

Mounting the S688 in warm air supply duct can
reduce the sail life.

Mount the switch at least 6 in. (152 mm) upstream from
an elbow or junction, and at least 15 in. (381 mm)
downstream from an elbow or junction. Locate the switch
on the opposite side of the duct from the air entrance.
(See Fig. 1-3 in S688 Installation Instructions.)

• 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.)

• 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 feed water tubing
provided is adequate to connect the water supply
(saddle valve) with the humidifier solenoid valve.

• 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 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.

• Select location with access to an outlet. If not
available, contact an electrician to have one installed.
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, to the plug-in
transformer in the outlet.
