Checking the Humidifier for Proper Operation
To check your humidifier for proper operation after servicing or winter startup, follow
these procedures:
1. Turn the furnace blower to the OFF position, making sure the solenoid valve is
closed.
2. Turn the furnace blower ON and set the humidistat to the ON position. The solenoid
valve should open.
3. Make sure the water flow from the solenoid falls directly into the distribution tray.
(The solenoid valve should limit the flow to approximately four gallons per hour at a
line pressure of 60 PSI.)
4. To avoid overflow, run the humidifier long enough to be sure the drain tubing is
carrying water to the waste line.
WARNING: DO NOT SET HUMIDITY CONTROL TOO HIGH. Use the
recommended settings shown on the humidistat cover plate.
