Troubleshooting Requirements

Ensure the installation meets the installation requirements outlined in the Installation
Chapter of this manual.

Familiarize yourself with the operation of the humidifier by reading the Operation Chapter of
this manual.

Wiring diagram specific for your humidifier is installed on the inside of the humidifier door. A
generic copy of the NH-EL wiring diagram is also included at the end of this chapter for
reference purposes.

When contacting your local representative or NORTEC for troubleshooting assistance, please
ensure the serial number has been obtained for reference purposes.
CAUTION: Be aware, when troubleshooting, that the humidifier is powered by high voltage.
Familiarity with both good practices and wiring of the humidifier is recommended. Any
troubleshooting that requires opening the cabinet should be done by qualified personnel.
NOTE: Most humidifier faults are not caused by faulty equipment but rather by improper
installation. A complete fault diagnosis always involves a thorough examination of the
entire system. Often, the steam hose connection has not been properly executed, or the
fault lies with the humidity control system.
