Preparing for the Installation

Required Accessories (Included)

Required Tools

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 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.

This installation kit contains all the parts necessary to install your new Honeywell HE220 or HE260 Humidifier.

INSTALLING HUMIDIFIER

• Select a location for the humidifier on the supply (warm air stream) or the return plenum. See Fig. 1.

• Select a location for the bypass on the opposite plenum. The sidewalls of the humidifier are interchangeable to allow bypass duct mounting on either side of the humidifier.

• Select a location that cannot damage the air conditioner A-coil during installation.

• Select a location where the 6 ft (1.86m) of 6 in. (155 mm) duct provided is adequate to connect the humidifier to the bypass. — Do not locate the humidifier or bypass on a fur-

nace body.

— Allow adequate clearance in front of and above

the humidifier so you can easily remove the cover to perform routine maintenance.

— Mount humidifier at least 3 in. (78 mm) above the

furnace body to allow adequate space for the solenoid valve and drain line.

— Mount humidifier in a conditioned space to pre-

vent freezing.

Fig. 1. Typical humidifier installation locations.

• Select a location for the sail switch in the cold air return duct where the sail is in the direct path of an unrestricted air stream. — Sail switch detects when furnace fan is operating.

• Select a location where the air duct is at least 12 in. (305 mm) deep and 8 in. (203 mm) wide to allow operation of the sail without affecting the smooth flow of air in the duct. — Airflow at the location can be vertical (up or

down) or horizontal.

IMPORTANT

Mounting the S688 in warm air supply duct can reduce the sail life.

Mount the switch at least 6 in. (152 mm) upstream from an elbow or junction, and at least 15 in. (381 mm) downstream from an elbow or junction. Locate the switch on the opposite side of the duct from the air entrance. (See Fig. 1-3 in S688 Installation Instructions.)

• 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.)

• 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.

• 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.

• Select location with access to an outlet. If not available, contact an electrician to have one installed. 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, to the plug-in transformer in the outlet.

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.

Turn off power to the air handing system at the cir-

cuit breaker. Draw a level line on the plenum in the location

chosen for the humidifier. (Leveling assures optimal humidifier performance.) Locate the template in the Humidifier Installation

Instructions. Tape the template in position and trace around the

template. Remove the template and carefully cut the rectan-

gular opening. Disassemble the humidifier; remove the cover and

take out the humidifier pad assembly. See Fig. 3.

NOTE: Sidewalls are interchangeable for either left or

right bypass installation. To change direction, remove the screws holding each sidewall, reverse sidewall locations, and reinstall the screws.

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

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.

Use the self-piercing 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 3/16 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 inline filter, be sure to install the saddle valve handle pointing toward the ceiling.

To avoid sagging and stress on humidifier, add support if ducting is longer than 4 ft (1.25m).

Seal the duct connections with duct tape.

Fig. 8. Installing saddle valve.

Use 1/4 in. (6 mm) OD tubing and connect saddle

valve to inlet side of the solenoid valve (see Fig. 9). a. Place brass compression nut over 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. Mod-

erate tightness prevents leaking.

e. Repeat steps a. through d. for saddle valve fit-

ting.

f. Secure tubing with clamps provided.

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 termi-

nates at the drain.

components, leaving adequate wire at both ends for connections.

NOTE: Transformer, humidistat and sail switch can be

wired in any order.

At the humidifier, connect the black and white con-

ductors to the two black humidifer wires. At the transformer, connect both black conductors

to the two transformer terminals. Use a wire nut to connect together the two white conductors. At the humidistat, connect both black conductors to

the two humidistat terminals. Use a wire nut to connect together the two white conductors. At the sail switch, connect the black and white con-

ductors to the Com and NO sail switch terminals (NC terminal is not used).
