Question about Aprilaire 550 Humidifier
This is supposed to be fairly simple I am told - does anyone know how?
You should have a humidistat that should shut it off when set to zero. if the water solenoid is stuck, water will keep coming out even when the system is not heating. all humdifiers will have a water line ran to them. yours is most likely a 1/4"copper line that runs from the water solenoid on the side or bottom of the humidifier to a saddle valve on one of your water lines. this saddle valve is usually installed very close to the water heater. follow the line to the valve and shut the water off. sometimes you have to loosed the nut on the water valve to get it to turn easily. do not loosend the nut more the 1/4 turn and then make sure you tighten it back down after shutting the water off.
