HE360 Humidifier

Installation Kit

WELCOME

To the comfortable world of humidified air. When you use

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

zapping

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.

APPLICATION

This installation kit contains all the parts necessary to

install your new Honeywell HE360 Humidifier.

• Allow adequate clearance in front of and above the

humidifier so you can easily remove the cover to

perform routine maintenance.

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

the furnace body to allow adequate space for the

solenoid valve and drain line.

— Mount the humidifier in a conditioned space to

prevent freezing.

Fig. 1. Typical humidifier installation locations.

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 feed water tubing

provided is adequate to connect the water supply

(saddle valve) with the humidifier solenoid valve.

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 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 Sail Switch

• 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.)

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.)

Fig. 2. Selecting duct location for humidistat.

Locating Closest 120V 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 (6.2m) of thermostat wire is

adequate to reach from the humidifier solenoid, to the

sail switch, to the humidistat.
