Troubleshooting | 40
Organization of Troubleshooting Chapter
The troubleshooting chapter is broken down into 2 sections.
General Troubleshooting
Deals with troubleshooting incorrect humidifier operation,
steam line and plumbing issues without any control
software faults.
Humidifier Warnings and Faults Deals with faults that are generated by the humidifier’s
control software.
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 on
page 24 and the section describing How the Humidifier Works on page 9 in this manual.
 A generic copy of the MES2 wiring diagram is 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.
NOTE:
 Check if yellow service LED is flashing before turning off the humidifier to determine if
a fault has occurred. See Figure 20 on page 24 and Table 7 on page 43.
 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.
CAUTION: Be aware, when troubleshooting, that the humidifier is powered by high voltage
and familiarity with both good practices and wiring of the humidifier is recommended.
Any troubleshooting should be done by qualified personnel.
