GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
MAINTENANCE
COOL DOWN PROCEDURE
Before performing any maintenance, allow the tank to cool down.
• Insulated and uninsulated tanks will have hot surfaces.
• Verify that there is no call for humidity and that the aquastat set point
(adjusted using the display screens in Settings/Water Management) is less
than room temperature (default setting is 50 °F [10 °C]) so the burners do
not energize while cooling down the tank.
• Use the display to perform the cool down process.
1. Go to the Home screen.
2. Change mode to Drain, and allow approximately half the water to drain
out of the tank. The fill valves may also be on to temper the water.
3. Change the mode back to Auto; the fill valve opens and the humidifier
cools down with the additional cool water.
4. When the fill valve closes, go back into Drain mode, and allow the tank to
drain completely. The humidifier should be cool enough to work on.
Note: For more information about using the display, see the

Water quality and maintenance
RO/DI WATER QUALITY RECOMMENDATIONS
• Verify regularly that water processing equipment is operating correctly. The
presence of chlorides in improperly processed DI water can cause pitting
and failure of the tank and heat exchanger. Your DriSteem warranty does
not cover damage caused by chloride corrosion.
• GTS humidifiers that use RO/DI water do not require regular cleaning,
although regular inspections are advised.
• GTS humidifiers that use RO/DI water do not require skimming or draining
and flushing to remove precipitated minerals. However, at the end of
a humidification season, drain all DI humidifiers by programming the
humidifier to automatically drain at end-of-season.
