OPERATION

When relative humidity falls to humidistat set point, the humidistat
switch makes contact and starts humidifier. In some central unit
humidifier systems, furnace fan must be operating before humidi-
fier will start. An increase in relative humidity above set point will
stop humidifier.

VI.

CHECKOUT

Place system in operation and observe at least 1 complete cycle to
make certain that all components are functioning properly.
