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.

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.

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.

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.)

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.

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  
to start the cut in the middle of the circle. Cut in an  
outward spiral to assist in controlling the cut.
