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. STEP ONE: Initiate a Flush Cycle 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. 1 Manual Drain Procedure Press and hold the Drain and Go buttons 2 simultaneously to interrupt the water cooling cycle and immediately drain the tank. OPERATION AND SERVICE M29628 CAUTION: Burn and Scalding Hazard. Use extreme caution when using the manual drain procedure. The water exiting the TrueSTEAM may be as hot as 212ºF. Make sure the drain outlet can handle up to 212ºF (100ºC), or wait at least 45 minutes to allow the water to cool before using this feature. 46 TrueSTEAM Humidification System 69-2285-01
