What does a Solenoid Valve Do?

A solenoid valve controls the water flow to your humidifier, it chooses whether the humidifier has access to water flow or not from your water supply. If

the solenoid valve is closed, it will not allow water to flow to your humidifier. Only when the valve is given 24 Volts will it open and supply water to the humidifier to product humidity. (it is given these volts when the humidifier is turned on by the homeowner or by the humidistat). 

 

24 volts, 60 Hz, Orifice 3/32.
Five (5) years from date of installation by a professional Installer - to be free from defects in materials or workmanship.
