NH-EL Warnings and Faults
The self-diagnostic system built into the NH-EL is continually monitoring the operation of the
humidifier. When the display shows a warning or fault condition you can find out more
information about the fault by pressing on the warning/fault box. This will display a screen
listing any warnings/faults that are in effect. Pressing on any item in the list will provide a
description as well as causes and possible corrective actions.

Warnings

When problem symptoms are detected, the NH-EL will attempt to take self-corrective actions
to try to correct the problem. A warning is displayed on the screen for information purposes
and the humidifier continues to operate.

If the condition which generated the warning is eliminated the warning is cleared from the
display.

While a warning is displayed the status LED is Yellow.
Faults

If the humidifier is not able to self-correct a problem symptom it will, if necessary, respond
by shutting down.

When this occurs, the humidifier illuminates the red “Fault” LED, shuts off power to the
cylinder, and drains the cylinder.
Clearing a Fault

Check the fault message that the humidifier is displaying and take any necessary actions to
correct the cause(s) as outlined in Table 11: Troubleshooting Warnings and Faults.

Power cycle the humidifier with the On/Off switch waiting 3 seconds between turning it off
and on.
