CLEANING AND
MAINTENANCE
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
.
The Steam Humidifier automatically flushes out the
water tank periodically 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, the Steam
Humidifier refills the tank with fresh water, and
automatically returns to normal operation.
Automatic flush is performed regularly, based on the number of hours that the Steam Humidifier heats water and
produces steam. Automatic flush can be set to occur at any of the following intervals:
Your Professional Installer set the Steam Humidifier to flush at the appropriate interval for your installation. During
any service call, the automatic flush interval can be changed, if desired.
