Sequence of Operation
Humidier will only operate when indoor blower is
operating.
When the level of moisture in the return air or living
space area drops below the set point of the humidier
control, the water solenoid valve opens, water ows
into distribution tray and weeps down through the
evaporator pad. By-pass air ows over the evaporator
pad, increasing the humidity of the air, and then back
into the return air stream. When the humidier control
is satised the water solenoid valve closes.
