Legacy Series Humidifier:

Choosing a GeneralAire® Humidifier will improve your comfort indoors and maintain a heathy environment so you can breathe a little easier.

The operating principle of the humidifier is based on the most efficient and economical means of evaporating water into the air. The heat necessary for evaporating water is produced by the furnace. The 1137L Fan Powered Humidifier mounts on the warm air plenum.

The water supply to the humidifier is controlled by the electronic solenoid valve. The solenoid valve and the humidifier fan are controlled by a humidistat connected through an isolation relay. The humidistat is designed for wall mounting in the living area or surface mounting on the return air duct.

5 Year for Solenoid and Relay; 1 Year Coverage for Fan
