HE360 HUMIDIFIER AND INSTALLATION KIT

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

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 sole-

noid 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.

• Mak e sure t hat the 20 ft (6 .2m) of feed wat er tubi ng 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 (6.2 m) of thermostat wire is adequate to reach from the humidifier solenoid, to the pressure switch, to the humidistat.

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.

Use hot or cold water and either hard or softened water in the humidifier.

1. Shut off the water.

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 3/16 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 valve on 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 compression 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.

NOTE: Do not over-tighten the compression nut. Moderate tightness prevents leaking.

e. Repeat steps a. through d. for solenoid valve fitting. f. Secure tubing with clamps provided.

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 tubing. b. Push the tubing over the drain nipple on the humidifier. c. Tighten the clamp around the tubing using a pliers/hand to secure the humidifier drain. d. Fasten the drain tubing (can use duct tape) along the route to prevent movement and ensure down-

ward slope for correct drainage.

NOTE: Cut tubing to correct length so the tubing terminates at the drain.

2. Mount the switch vertically with pressure

connectors facing down, using provided selftapping screws to secure the switch to the duct.

3. Cut 3/4-in. diameter holes in the supply and

return ducts within 10 feet of the switch to ensure the provided tubing reaches the pressure tap elbows. See Fig. 9.

4. Insert the black rubber gaskets into the duct

holes.

5. Connect the tubing to the tubing fitting elbows

and insert the tubing fitting elbows into the black rubber gaskets in each duct.

WIRING

Hazardous Voltage. Can cause personal injury or equipment damage.

Disconnect power supply before installing or servicing equipment.

IMPORTANT

— Use THIS wiring diagram—NOT the one supplied with humidistat instructions. — All wiring must comply with applicable local code, ordinances and regulations.

Wire the humidifier solenoid valve, pressure switch and humidistat. See Fig. 12.

NOTE: It is acceptable to switch the position of the red and white wires when wiring the equipment.

Fig. 12. Wiring the controls.

1. Run the two-strand thermostat wire from the humidifier to the humidistat, and from the humidistat to the

pressure switch.

2. Cut two (2) 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, use one length of thermostat wire to connect a red wire to one of the yellow humidifier

wires and a white wire to the remaining yellow humidifier wire. (The red wires from the humidifier are not used.)

4. At the pressure switch, use the remaining length of thermostat wire to connect a red wire to the C terminal

and a white wire to the NO terminal using spade connectors and pliers. (The NC terminal is not used.)

5. Connect the white wires from each length of thermostat wire to each of the black wires of the humidistat

using wire nuts.

6. Connect the remaining red wires together using a wire nut.
