Routine Maintenance

TrueSTEAM automatically flushes the tank throughout the humidifying season. This lowers the water hardness
concentrated in the tank, and slows the accumulation of solid minerals.

Automatic Cleaning Cycle

• The automatic cleaning cycle takes about 45 minutes. During this time, TrueSTEAM will not produce
any steam.
• Cold water will enter the tank to lower water temperature below 140°F (60°C) before draining.
• At the end of the cycle, TrueSTEAM refills the tank with fresh water and automatically returns to
normal operation.

Manual Cleaning Cycle

Honeywell recommends that TrueSTEAM be manually cleaned and the water filter be changed at least
once each humidification season. The manual cleaning is necessary to remove solid mineral deposits left
behind during operation.

Solid material deposits in the tank are normal. The
homeowner should expect to see some buildup in the
tank and on the heating element.
• When the Cleaning Required light is on, manual
cleaning is needed. TrueSTEAM will still operate as
normal while this light is on.
• Before removing the TrueSTEAM tank, it must be
completely drained.
To begin draining the tank, press and hold the Drain
button until the Draining light blinks.
