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 H8908 Humidistat to On 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 Humidifier section.
4. Check for leaks.
5. Reset the thermostat and H8908 Humidistat to a comfortable setting for auto-
matic operation.
Controlling Your Humidity Settings
Your H8908 Humidistat controls your humidifier.
• Choose the humidity control setting using the combination of relative humidity/
outdoor temperature setting scale on your humidity control dial.
• Match the dial setting to the outdoor temperature to optimize the humidity level
while reducing the moisture condensation on your windows. See Table 2 to adjust
the humidity control to the recommended setting.
NOTE: As the outside temperature drops, a lower humidity setting is recommended
to accommodate dewpoint effects. These settings should reduce the accumu-
lation of moisture and ice on windows and other areas of the home.
• Adjust the humidity control setting to adjust for indoor activities such as cooking,
showering and clothes drying, which can cause excessive levels of humidity that
can accumulate moisture on your windows.
NOTE: If these activities persist for more than a few hours, set the humidity control to
the lowest setting to turn off the humidifier. If the condition does not improve,
ventilate your home to remove the moisture.
