HE220A,B AND HE260A,B BYPASS FLOW-THROUGH HUMIDIFIERS
NOTE: Be sure to install a duct damper for summer shutoff on
systems with air conditioning.
9. Install a 6 in. (152 mm) diameter duct from the collar to the
humidifier.
NOTE: Some installations require a 90° elbow attachment to the
collar.
10. Seal the duct connections with duct tape.
NOTE: To avoid sagging and stress on the humidifier, add support
when ducting is longer than 4 ft (120 cm).
11. Reinstall the humidifier pad assembly in the humidifier housing.
NOTE: Be sure the water feed tube is not pinched or kinked.
12. Hinge the cover in place and secure with the thumbscrew located at
the bottom of the cover.
WIRING
WARNING
Hazardous Voltage.
Can cause personal injury or equipment damage.
• Disconnect power supply before installing or servicing.
• On multispeed blower applications, do not wire the high voltage
side of the transformer to the same power source that services
the furnace blower or the transformer may burn out prematurely.
All wiring must comply with applicable local codes, ordinances and
regulations.
1. Mount the transformer in a convenient location.
IMPORTANT
Install transformer on the outside of a grounded metal junction
box using only a 7/8 in. (22 mm) knockout hole. Place mounting
tabs into the knockout hole and firmly tighten the locking screw.
Field wiring connections and grounding means for the trans-
former and enclosure shall be in accordance with the National
Electrical Code (NEC) and the Canadian Electrical Code (CEC).
2. Connect wires to the 120V side of the transformer.
For humidity control wiring connections:
1. Wire the humidifier solenoid valve, current sensing relay or sail
switch, humidity control and transformer. Refer to the humidity
control installation instructions for mounting and wiring information.
IMPORTANT
• For proper operation, the humidifier must be energized during
blower motor cycles.
• Current sensing relay or sail switch is not needed with the
Automatic Humidity Control.

PLUMBING SADDLE VALVE

Hot or cold water, either hard or softened, can be used in the humidifier.
1. Use the self-piercing saddle valve (included) to tap into the water
supply line at an appropriate location.
WARNING
Chemical Hazard.
Can cause personal injury or equipment damage.
Do not use any line connected to an air conditioner.
IMPORTANT
• The saddle valve is not designed to be used to regulate water
flow. The valve is either open or closed.
• To prevent debris from clogging the solenoid in-line filter, be sure
to install the saddle valve handle pointing toward the ceiling.
NOTE: Lightly clean the copper tubing ends with fine sandpaper
before making any connections.
2. Use 1/4 in. O.D. copper tubing and connect the saddle valve to the
inlet side of the solenoid valve.
a. Place the brass compression nut over the copper tubing.
b. Slide the brass ferrule over the tubing.
NOTE: Do not over-tighten the compression nut. Moderate tight-
ness will prevent leaking.
c. Insert the tubing into the solenoid valve fitting and support the
valve while tightening the compression nut.
NOTE: Slope drain tube downward for correct drainage.
3. Connect a 1/2 in. drain tube to the humidifier drain fitting and run to
a suitable drain.
CHECKOUT
1. Open the saddle valve.
NOTE: The furnace blower must be on for the humidifier to
operate.
2. Set the thermostat setpoint 10°F (6°C) above the room temperature.
3. Set the Convertible Humidity Control to a high humidity setting, or
place the H1006A Automatic Humidity Control in the test position.
4. Observe the water running out of the drain line to be sure the humid-
ifier is working properly.
5. Check for leaks.
6. Reset the thermostat and Convertible Humidity Control to a comfort-
able setting, or the Automatic Humidity Control to the desired frost
factor setting.
