41 | Maintenance and Servicing
Required Maintenance
The RH2 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 cleaning out the drain valve whenever the
cylinder is replaced.
Cylinder Spent Fault
When the cylinder is spent the RH2 will stop operating and the yellow LED will flash in a
repeating pattern of 4 flashes. See Table 8: Troubleshooting RH2 Faults on page 51 for more
information on other flash sequences. At this time the cylinder must be replaced.
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.
Replacement Cylinder
The label on the existing cylinder identifies the cylinder type in its top left corner. When ordering
a cylinder always quote the three or five digit model number on the label, the humidifier’s serial
number and the humidifiers voltage. Serial number and voltage are located on the specification
label on the left side of the humidifier.

Note: Nortec recommends keeping a replacement cylinder in stock throughout the
humidification season. This will prevent possible downtime when the humidifier
reports cylinder end of life.
Caution: Failure to replace the cylinder at the end of cylinder life will result in improper
operation and may result in damage to the humidifier. Nortec is not responsible for
any damages resulting from, or attributed to, the failure to replace a spent cylinder
(see Manufacturer’s Warranty).
