If the humidifier does not start, increase the setpoint of the humidistat.
Mist is carried through mist guide by the fl ow of air from the AHU’s fan. The mist is delivered
through the ductwork thus humidifying the surrounding air.
The
humidifier starts and stops by means of a signal from the control box.
8.
During operation, the water level in the tank is maintained by the level controller.
9.
