9. Alarms, Troubleshooting
Alarms are indicated on the front display panel by a sequence of flashes of the red alarm LED. In the
event of more than one alarm, these are indicated in sequence. Even if no longer active, the
alarm status continues to be displayed by the flashing of the LED and the operation of the
humidifier is stopped while the alarm is still present. To clear the inactive alarms, the humidifier
must be turned off, and then on again. Active alarms cannot be reset by restarting the
machine.
LED flash modes: slow flashes - 1 flash every 2 seconds; quick flashes - 2 flashes per second;
the signals are repeated continuously, and the LED stays off for 3 seconds between one signal
and the next.
