• There is not enough water in the chamber, or

Note:

AUTODRAIN SEQUENCE MINIMIZES OUTPUT INTERRUPTIONS
The humidifier drains and flushes automatically at regular intervals to remove minerals from the chamber.
After the humidifier has run for a preprogrammed amount of time, and if there is no demand for humidity, the humidifier sits idle
until the chamber cools and then it drains.
If the humidifier has not completed an autodrain sequence due to continual demand signal interruptions, after an additional
amount of run time the humidifier begins a cool-down period and then it drains.
IMPORTANT: The humidifier attempts to complete an autodrain sequence when there is no demand for humidity. However,
if an autodrain sequence is not completed within a defined period of time, the humidifier ignores the demand signal until
completing an autodrain sequence. This could cause the relative humidity level in the humidified space to drop until the autodrain
sequence completes.
