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.

Required Tools
Tools required for installation include:
• Tin snip.
• Screwdriver.
• Adjustable or open-end wrench.
• Drill, punch or awl.
•Level.
• 3/4-in. Sheet Metal Drill Bit
Determining Best Location for
Humidifier
• Select a location for the humidifier on the supply (warm
air stream) plenum. See Fig. 1.
• Select a location that cannot damage the air
conditioner A-coil during installation.
• Do not locate the humidifier on the furnace body.
• 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 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.

1. Turn off power to the air handing system at the cir-
cuit breaker.
2. Draw a level line on the plenum in the location
chosen for the humidifier. (Leveling assures optimal
humidifier performance.)
3. Locate the template in the Humidifier Installation
Instructions.
4. Tape the template in position and trace around the
template.
5. Remove the template and carefully cut the rectan-
gular opening.
6. Disassemble the humidifier; remove the cover and
take out the humidifier pad assembly. See Fig. 3.
Fig. 3. Disassembling humidifier.
7. Make sure the humidifier housing is level, then posi-
tion it in the opening so the plastic tabs are in place
on the lower sheet metal edge of the opening. Use
pliers, as necessary, to flatten cut edges. See Fig.
4.
8. Secure the humidifier housing to the opening at the
top and bottom using sheet metal screws.
Fig. 4. Installing humidifier on duct.
9. Reinstall the humidifier pad assembly in the humidi-
fier housing.
IMPORTANT
Be sure to reconnect the water feed tube and
ensure that the tube is not pinched or kinked.
10. Hinge the cover in place and secure with the thumb-
screw located at the bottom of the cover.
Connecting the Plumbing
1. Shut off the water.
CAUTION
Chemical Hazard.
Can cause personal injury or equipment
damage.
Do not use any line connected to an air
conditioner.
Do not use gas line.
2. First, connect 1/4-in. line to the humidifier’s sole-
noid valve, located at the bottom of the humidifier.
a. Remove the compression nut.
b. Discard the brass ring, replacing it with the plas-
tic ring.
c. Install the brass insert into the end of the tubing.
d. Insert the tubing into the solenoid valve fitting
and support the valve while tightening the com-
pression nut.
NOTE: Do not over-tighten the compression nut. Moder-
ate tightness prevents leaking.
3. Use the saddle valve (included) to tap into the water
supply line at the location selected. See Fig. 8. If
tapping into galvanized pipe, drain line and pre-drill
3/17-in. tap for saddle valve.
NOTE: The saddle valve is not designed to regulate
water flow. The valve is either open or closed.
IMPORTANT
To prevent debris from clogging the solenoid in-
line filter, be sure to install the saddle valve han-
dle pointing toward the ceiling.
Fig. 5. Installing feed tubing.
4. Use 1/4-in. (6mm) OD tubing and connect the sad-
dle valve to the inlet side of the solenoid valve on
the humidifier (See Fig. 9).
5. Repeat step 2, a - d for saddle valve fitting.

Air Pressure Switch Installation
IMPORTANT
Do not install the switch in an area where tem-
perature exceeds rating of -40F to 190F (-40C to
88C)
1. Disconnect power from the humidifier before install-
ing.
2. Mount the switch vertically with pressure connec-
tors facing down, using provided self-tapping
screws to secure the switch to the duct.
IMPORTANT
Calibration accuracy requires that the switch be
mounted vertically (as pictured in Fig. 7).
Fig. 7. Pressure switch—oriented vertically.
3. The return duct is recommended, however the
switch can also be mounted to the supply duct.
Fig. 8. Mounting the pressure switch.
4. Cut a 3/4-in. diameter hole in the duct within 10 feet
of the switch to ensure the provided tubing reaches
the pressure tap elbow.
5. Insert the black rubber gasket into the duct hole.
6. Connect the tubing to the tubing fitting elbow and
insert the tubing fitting elbow into the black rubber
gasket.
7. Connect the other end of the tubing to the applica-
ble pressure connection on the switch.
e. Black connection if installed on the supply
f. Grey connection if installed on the return
g. Both grey and black if installed on both
IMPORTANT
With low-speed airflow or variable speed sys-
tems it is recommended to run tubing to both the
supply and return ducts.

You may cut the tubing to fit the connection length
between the tubing fitting elbow and switch. It is also

Installing Humidistat
Mounting Duct
1. Apply the template to the duct location chosen for
the humidistat. Make sure the template is level
before drilling the holes.
2. Refer to the template (provided with the H8908
Humidistat Installation Instructions) to drill the con-
trol assembly opening and mounting holes for the
H8908.
3. Remove the H8908 case from the base.
4. Position the foam gasket on the H8908 base.
5. Position the base on the duct with the arrow up.
6. Secure the base to the duct using the four
1 in. (25 mm) mounting screws provided with humi-
distat.
7. Connect the low-voltage wires to the leads and
replace the H8908 case. See Fig. 11.
NOTE: For wall mounting instructions, see the H8908
Installation Instructions.

WIRING
CAUTION
Hazardous Voltage.
Can cause personal injury or equipment
damage.
Disconnect power supply before installing or
servicing equipment.
IMPORTANT
All wiring must comply with applicable local
code, ordinances and regulations.
Wire the humidifier solenoid valve, pressure switch,
humidistat and transformer.See Fig. 12.
Fig. 11. Wiring the controls.
Fig. 12. Close-up of pressure switch wiring.
1. Run the two-strand thermostat wire from the humid-
ifier to the humidistat, and from the humidistat to the
pressure switch and back to complete the wiring
loop to the humidifier.
2. Cut lengths of thermostat wire to reach between
components, leaving adequate wire at both ends for
connections.
NOTE: Humidistat and pressure switch can be wired in
any order.
3. At the humidifier, connect the black and white con-
ductors to the two yellow humidifer wires. (The red
wires from the humidifier are not used.)
4. At the humidistat, connect both black conductors to
the two humidistat terminals. Use a wire nut to con-
nect together the two white conductors.
