Caution: scalding Hazard.
Initial temperature of the drain water may be above 140
° F (60 ° C) and can cause scalding injury.
Make sure the drain outlet is not exposed, and use caution when pressing the Drain button .
TrueSTEAM automatically flushes out the water tank
during the humidifying season. In the automatic
flush cycle, cold water enters the tank while water
is being emptied through the drain line. The action
of simultaneous filling and draining cools the water
to a safe draining temperature. It also dilutes water
hardness concentration to reduce mineral deposits
from forming in the tank.
At the end of the automatic flush cycle, TrueSTEAM
refills the tank with fresh water, and automatically
returns to normal operation.
Automatic flush is performed regularly, based on the number of hours that TrueSTEAM heats water and produces
steam. Automatic flush can be set to occur at any of the following intervals:
Your Professional Installer set TrueSTEAM to flush at the appropriate interval for your installation. During any
service call, the automatic flush interval can be changed, if desired.
What is the automatic flush cycle?
autoflush intervals
8 hours (recommended for hard water)
12 hours (factory setting)
20 hours (when a water softener is installed)
30 hours (when an optional RO filter is installed)
