Seasonal or vacation maintenance
TrueSTEAM has the built-in intelligence to shut down when humidity is not needed for an
extended period. After 48 hours of inactivity, TrueSTEAM will drain its tank and remain empty
until it is needed again. This prevents water from stagnating within the tank. There are a few
house-cleaning steps to follow to keep your TrueSTEAM at peak efficiency:
1. Follow steps 1–6 in the Cleaning section on pages 7–8 at least once per year, or when the
Press Empty light is blinking.
2. Clear ventilation holes in the humidifier’s cover.
3. Clear the water drain tube.
4. Make sure the water tank gasket seal is not cracked or split before reattaching the
humidifier water tank.
5. Check that the humidifier is still level.
Extended Vacation
When you leave on extended vacations, it is recommended you turn off the humidifier’s water
supply and turn off the humidity control. When you return, turn on the humidifier water supply and
reset your humidity control to a comfortable position.
