HE240, HE280 HUMIDIFIER
1. Determine the length of wire necessary to run from the humidifier to the humidistat. Cut to length and
strip the ends appropriately.
2. Connect the red and white wires to the C and lower U terminals on the humidistat per the wiring diagram.
3. Taking the opposite end of the wire, connect RED WIRE to one terminal on the humidifier. Connect the
WHITE WIRE to the other terminal at the humidifier.
4. Using remaining wire, determine length needed to run from H6062 Humidistat to the transformer. Cut to
length and strip the ends appropriately.
5. With transformer unplugged, connect the red and white wires to the transformer by loosening the screws
on the transformer, wrap wire around screw post and then re-tighten the screws.
6. Taking the opposite end of the wire, connect the RED WIRE to the R terminal at H6062 and the WHITE
WIRE to C at H6062.
7. Cut a short wire. Connect one end of that wire to R and the other end to the upper U at H6062.
TESTING HUMIDIFIER OPERATION
Checklist
Humidifier is level.
Control wiring was reviewed using circuit diagram.
Transformer 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 PerfectFLO
Tubing from pressure switch is not kinked or pinched.
After installation use the following steps to check the humidifier operation:
1. Turn on the power and the water supply
2. Ensure the shut off valve is fully opened. If saddle valve from HUMKIT is used, turn the handle to the left
(counter clockwise) until there is resistance.
3. Turn the H6062 all the way up and turn on the heat by setting the thermostat to 10 ºF (6 ºC) above room
temperature.
IMPORTANT
The furnace blower must be on to activate the humidifier.
4. Make sure that water is flowing out of the drain hose. If water does not flow, see Troubleshooting Your
Humidifier section.
5. Check for leaks.
6. Reset the thermostat and H6062 Humidistat to a comfortable setting for automatic operation. (35%
relative humidity is recommended.)
OPERATION
Controlling Your Humidity Settings
Your H6062 Humidistat controls your humidifier.
• Choose the humidity control setting using the combination of relative humidity/outdoor temperature setting
scale on your humidity control dial.
• When the outdoor sensor is used, the H6062 will optimize the humidity level while reducing moisture
condensation on the windows. See the H6062 instructions for settings and adjustments.
