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.
NOTE: Select models of fan centers include humidifier taps so the
current sensing relay or sail switch are not needed.
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 sand-
paper 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
tightness 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 Humidity Control to a high humidity setting, or place the
setting in the test position.
4.
Observe the water running out of the drain line to be sure the
humidifier is working properly.
5.
Check for leaks.
6.
Reset the Humidity Control to a comfortable setting, or the
Automatic Humidity Control to the desired frost factor setting.
