WIRING
CAUTION
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. 16.
NOTE: It is acceptable to switch the position of the red and white wires when wiring the equipment.
1. Run two, two-strand thermostat wire bundles from the humidifier to the humidistat. Run one, two-strand
thermostat wire bundle from the humidistat to the pressure switch.
2. Cut lengths of thermostat wire to reach between components, leaving adequate wire at both ends for con-
nections.
3. At the humidifier, connect the two red wires to the red and white wires from wire bundle 1.
4. At the humidifier, connect the two yellow wires to the red and white wires of wire bundle 2.
5. At the humidistat, connect the red and white wires from bundle 1 to R and C (polarity doesn't matter).
6. At the humidistat, connect the red wire from bundle 2 to the upper U terminal.
7. At the humidistat, wire-hut the white wire from bundle 2 to the white wire in bundle 3 (going to the pres-
sure switch).
8. At the humidistat, wire the red wire from bundle 3 to the lower U on the humidistat.
9. At the pressure switch, connect the red and white wires from bundle 3 to the C and NO pressure switch ter-
minals. (NC terminal is not used).
TESTING HUMIDIFIER OPERATION
Checklist
Humidifier is level.
Control wiring was reviewed using circuit diagram.
Humidifier is plugged in.
Feed line has no kinks.
Drain line slopes continuously down and ends at floor drain.
Water hose inside humidifier is connected to PerfectFlow™ water distribution tray.
After installation use the following steps to check the humidifier operation:
1. Turn on the power and the water supply.
2. Turn the H6062 Humidistat all the way up and turn on the heat by setting the thermostat to 10ºF (6ºC)
above room temperature.
IMPORTANT
The furnace blower must be on to activate the humidifier.
3. Make sure that water is flowing out of the drain hose. If water does not flow, see Troubleshooting Your
