WIRING HUMIDIFIER
WARNING
Serious Personal Injury or Equipment Hazard.
Moving parts can cause electrical shock and
injury.
• Disconnect power supply before installation or
servicing.
• This device contains a moving fan blade; do not
operate the humidifier without the cover securely
attached.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
H8908 Humidistat Wiring Connections
IMPORTANT
• Select models of fan centers include humidifier taps
so the current sensing relay or sail switch is not
needed.
• If not using a current sensing relay or sail switch, the
120V humidifier plug must be energized during
blower motor cycles for proper operation.
1.
Wire the current sensing relay or sail switch.
2.
Connect only the two yellow wires to the humidity
control (red wire connections are not used for
mechanical humidity control).
NOTE: For additional mounting and wiring information, refer
to the humidity control installation instructions.
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.
CAUTION
Equipment Hazard.
Improper installation can cause equipment
damage.
Do not use any line connected to an air conditioner.
IMPORTANT
• The saddle valve is not designed to regulate water
flow; the valve is either open or closed.
• Be sure to install the saddle valve handle pointing
toward the ceiling to prevent debris from clogging the
solenoid in-line filter.
NOTE: Lightly clean the copper tubing ends with fine
sandpaper before making any connections.
