Inspection
1. Annually (also recommended when maintenance is performed)
• All safety devices in the control circuit should be cycled on
and off to verify they are functioning. These include:
– High limit switch
– Airflow proving switch
– Low water cutoff switch
– Redundant low water cutoff switch
• Inspect tank and gaskets for leaks.
• Verify that the float valve is closing off. If the float valve will
not shut off, there may be particulate on the valve seat, or the
EPDM seat may be worn and in need of replacement.
• As long as mineral-free water is used in the GTS, no cleaning
or flushing of the humidifier should be necessary.
2. Seasonally (or as required, depending on water quality)
• Inspect blower motor. Since a lubrication port is not provided,
lubrication is not required.
• Remove dust — Using a vacuum, remove all dust from areas
around the motor, vent fan(s), and louvers that allow air to
the shaded area.
3. Off-season maintenance
• Perform a complete inspection of the following:
– Float valve
– Low water cutoff switch
– Redundant low water cutoff switch
– Humidifier tank and gaskets
– Heat exchanger
• Drain humidifier tank and rinse.
• After inspection, the humidifier should remain empty until
humidification is required.
