Required Maintenance
Service Warning / Fault
The SETC controller includes a timer that monitors the humidifier’s operating hours and
generates a warning when service is required. Optimal maintenance time is dependent on
water supply conditions and humidifier usage. The default factory service reminder is equivalent
to 500 hours of operation at 100% output. Failure to perform maintenance when the service
warning is displayed will cause the unit to lock out. Nortec is not responsible for any damages
resulting from, or attributed to not performing required maintenance. (See Manufacturer’s
Warranty).
Warning
When the software determines that
the service timer has elapsed it first
displays a warning and turns on the
yellow service LED. The humidifier
will continue to operate for another
200 hours after the warning is
displayed.
Fault
After 200 hours the humidifier will
display a fault and shut down.
If maintenance is not possible the
humidifier can be temporarily put
back into service by turning the
humidifier off and on. The
humidifier will run for another 200
hours.
This reset can be repeated 4 times
after which the humidifier will not
run until the Reset Service
Reminder function is entered in the
software’s service level.
Figure 47: Service Warning / Fault
Caution: Power to the humidifier should always be turned off using the dedicated external
