Nortec NH-EL Series - Manual (Page 66)

63 | Maintenance and Servicing
Required Maintenance
The NH-EL humidifier has been designed to require very little maintenance. Regular
maintenance consists of checking the humidifier to ensure it is in good condition, replacing the
cylinder when the software advises that the cylinder is spent (and changing the o-ring), as well
as cleaning out the drain valve whenever the cylinder is replaced.
Cylinder Spent Warning / Fault
The steam cylinder is disposable and must be replaced at end of cylinder life. Cylinder life is
dependent on water supply conditions and humidifier usage.
Warning
When the software
determines that the
cylinder is spent, it first
displays a warning and
turns on the yellow
service LED. The
humidifier will continue
to operate for another
72 hours after the
warning is displayed.
Fault
After 72 hours the
humidifier will display a
fault and shut down.
If a replacement
cylinder is not yet
available, the humidifier
can be temporarily put
back into service by
turning the humidifier
off and on. The
humidifier will run for
another 72 hours at
reduced capacity.
