7.3 General Troubleshooting
Most operational warning/fault conditions are caused by improper installation, or by not adhering
to the suggested best practices for installation of the humidifier and system components . Hence,
a full fault diagnosis always requires a thorough examination of the entire system (hose connections,
control systems, etc.).
Table 13 provides general guidelines for troubleshooting the humidifier. For detailed troubleshooting in -
formation of the auxiliary system components, refer to their product manuals.
