WELCOME
To the comfortable world of humidified air. When you use your Honeywell humidifier,
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.

Determining Best Location for Humidifier
CAUTION
Temperature and Static Pressure Hazard.
Can cause property or equipment damage.
Locate humidifier where ambient temperature is between 32°F (0°C) and
160°F (71°C).
Do not install humidifier where freezing temperatures could occur.
Be sure supply plenum static pressure is no greater than 0.4 in. wc and water
pressure is no greater than 124 psi.
• 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.)

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 pressure switch, to the humidistat.
Installing the Humidifier
WARNING
Hazardous Voltage
Can cause personal injury or equipment damage.
Do not cut or drill into any air conditioning or electrical accessory.
CAUTION
Sharp Edges Installation Hazard.
Can cause personal injury.
Wear gloves and safety glasses.
1. Turn off power to the air handing system at the circuit 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 (form number 69-2641 included in the box).
4. Tape the template in position and trace around the template.
5. Remove the template and carefully cut the rectangular opening.
6. Disassemble the humidifier; remove the cover and take out the humidifier pad
assembly. See Fig. 3.

8. Make sure the humidifier housing is level, then position it in the opening so the
plastic tabs are in place on the lower sheet metal edge of the opening. Use pli-
ers, as necessary, to flatten cut edges. See Fig. 5.
9. Push in securing clips until completely seated.
10. Drill holes and install the three sheet metal screws on the top of the humidifier
housing. Secure the housing with the three remaining screws.

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. 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 3/17 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 handle pointing toward the ceiling.
Fig. 6. Installing the saddle valve.
3. Use 1/4 in. (6 mm) OD tubing and connect the saddle valve to the inlet side of
the solenoid valveon the humidifier (see Fig. 7).
a. Place the brass compression nut over the tubing.
b. Install brass insert into end of tubing.
c. Slide the plastic compression ring over the tubing. (Discard copper compres-
sion ring provided with valve.)
NOTE: To prevent leaking, use plastic (Delrin) sleeve rings with plastic tubing. Use
copper sleeve rings only with copper tubing.
d. Insert the tubing into the solenoid valve fitting and support the valve while
tightening the compression nut.

4. Connect a 1/2 in. (13 mm) drain tube to
the humidifier drain fitting and run to the
floor drain (see Fig. 8).
a. Slide the drain clamp over the tub-
ing.
b. Push the tubing over the drain nip-
ple on the humidifier.
c. Hand-tighten the clamp around the
tubing to secure the humidifier drain.
d. Fasten the drain tubing (can use
duct tape) along the route to prevent
movement and ensure downward
slope for correct drainage.
NOTE: Cut tubing to correct length so the
tubing terminates at the drain.

Installing the Pressure Switch
IMPORTANT
Do not install the switch in an area where temperature exceeds rating of
-40°F to 190°F (-40°C to 88°C).
