HE120, HE160 Humidifier
Installation Kit
INSTALLATION INSTRUCTIONS
WELCOME
INSTALLATION
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.
Preparing for the Installation
Be sure to identify all the required (Table 1) accessories
(included) and make sure the appropriate tools are
available before beginning the installation.
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.

7. Position the HE120 Humidifier base in the opening,
mark the five screw holes, and pre-drill the screw
holes.
DISK WHEEL
8. Insert the three 3/4 in. (19 mm) sheet metal screws
into the top holes.
9. Hang the humidifier over the screws and secure
with the two remaining 1/2 in (13 mm) screws.
10. Inside the humidifier housing, where the bypass
tube connects, snap the bearing bracket into place
with the U-shape of the bracket pointing up.
11. Snap the motor plate into place on the opposite
side of the humidifier housing.
NOTE: Be sure the motor coupling is positioned toward
the top,
12. Place the lead wires through the hole in the bottom
of the motor cover and snap the cover into place.
NOTE: For HE120, go to Connecting Plumbing section.
For HE160, go to step 13.
13. Hold the hanger bracket against the duct/plenum
so the bottom of the hanger bracket is about 1/2 in.
(13 mm) from the top edge of the duct/plenum
opening. Ensure that it is level and mark the three
mounting bolt locations (Fig. 3A).
14. Drill three 3/16 in. (5 mm) holes in the duct/plenum

CONNECTING PLUMBING
1. Install the float into the slot in the side of the basin.
Hand-tighten the nut.
NOTE: For HE120, attach the float on the same side as
the motor; install the plug in the opposite slot.
2. Shut off the water. (Either hot or cold water and
either hard or softened water can be used in the
humidifier.)

d. Insert the tubing into the float valve fitting and
support the valve while tightening the compres-
sion nut.
CAUTION
Can cause personal injury or equipment
damage.
Do not use any line connected to an air
conditioner.
Do not use gas line.
Chemical Hazard.
NOTE: Do not over-tighten the compression nut. Mod-
erate tightness prevents leaking.
e. Repeat steps a. through d. for saddle valve fit-
ting.
f. Secure tubing with clamps provided.
3. Use the self-piercing saddle valve (included) to tap
into the water supply line at the location selected.
See Fig. 6. If tapping into galvanized pipe, drain
line and pre-drill 3/16 in. tap for saddle valve.

To prevent debris from clogging the solenoid in-
line filter, be sure to install the saddle valve han-
dle pointing toward the ceiling.

5. Connect a 3/8 in. (10 mm) overflow tube to the
humidifier overflow fitting and run to the floor drain
or bucket if floor drain is not available.
a. Insert overflow fitting. (HE160 fitting is provided
in the kit. HE120 fitting is provided with humidi-
fier; position it in hole opposite of float.)
NOTE: Be sure to install water pan with overflow posi-
tioned over fitting.

b. Slide the overflow clamp over the tubing.
c. Push the tubing over the overflow fitting on the
humidifier.
d. Hand-tighten the clamp around the tubing to
secure the overflow tubing.
Fig. 6. Installing saddle valve.
4. Use 1/4 in. (6 mm) OD tubing and connect saddle
valve to float valve (see Fig. 7).
e. Fasten the overflow tubing (can use duct tape)
along the route to prevent movement and
ensure downward slope for correct drainage.
NOTE: For HE120, use plastic compression nut for float
connection.
a. Place compression nut over tubing.
NOTE: Cut tubing to correct length so the tubing termi-
nates at the drain or bucket.
NOTE: For HE160, use brass expander insert for float
connection.
Adjusting HE160 Water Level (Fig. 8)
b. Install brass insert into end of tubing.
1. Test fit the disk assembly in the humidifier.
2. Turn on the water supply and check for leaks.
3. Adjust the float assembly so the water height just
covers the disks; verify that the water is within the
range of the textured bands inside the basin.
4. Adjust the float, as necessary.
NOTE: A compression ring is required only at the tub
end connected to the saddle valve.
c. Slide the plastic compression ring over the
tubing. (Discard copper compression ring pro-
vided with valve.)
5. Secure the float adjustment nut with a 9/16 in.
(15 mm) wrench.
6. Remove the disk and drain the water before begin-
ning the bypass installation.
NOTE: To prevent leaking, use plastic (Delrin) sleeve
rings with plastic tubing. Use copper sleeve
rings only with copper tubing.

INSTALLING BYPASS
1. Use inside of the 6 in. (155 mm) starter collar as a
template to mark the opening for the bypass.
2. Carefully cut the 6 in. (155 mm) opening for the
starter collar. See Fig. 9. Use a drill, punch or awl
