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 Humidier automatically ushes out the
water tank during the humidifying season. In the
automatic ush cycle, cold water enters the tank while
water is being emptied through the drain line. The
action of simultaneous lling 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 ush cycle, the Steam
Humidier rells the tank with fresh water, and
automatically returns to normal operation.
Automatic ush is performed regularly, based on the number of hours that the Steam Humidier heats water and
produces steam. Automatic ush can be set to occur at any of the following intervals:
Your Professional Installer set the Steam Humidier to ush at the appropriate interval for your installation. During
any service call, the automatic ush interval can be changed, if desired.
