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.
Cabinet
Rugged, corrosion resistant molded plastic.
Humidier is shipped for left-hand by-pass duct
connection.
For right-hand by-pass duct connection, rotate
humidier cabinet 180º top for bottom and relocate
drain spud. See Installation Instructions for additional
details.
