Cylinder Spent Warning / Fault - Nortec NHTC Installation And Operation Manual

Required Maintenance
The NHTC/PC humidifier has been designed to require very little maintenance. Regular
maintenance consists of checking the humidifier to insure it is in good condition, replacing the
cylinder when the software advises that the cylinder is spent and 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. Failure to replace the cylinder at
the end of cylinder life will cause the unit to lock out. NORTEC is not responsible for any
damages resulting from, or attributed to, the failure to replace a spent cylinder (see
Manufacturer's Warranty).
