Why Do I Need To Manually Clean The Tank; When Should I Clean The Tank; How Do I Clean The Tank - Honeywell HM609 Operating Manual

Why do I need to manually clean the tank?

Manual cleaning is needed at least once each season to clean out the mineral deposits that remain in the tank
after automatic flushing. Manual cleaning is easy – just empty and remove the water tank and clean the interior
components. Then re-assemble and start the Steam Humidifier up again.
• When should I clean the tank? The Steam Humidifier should be manually cleaned at least once every 5
months. (Hard water may require more frequent cleaning.) The Cleaning Required light turns on when the tank
needs manual cleaning. The Steam Humidifier will still operate normally when the Cleaning Required light is
on. The light will turn off when you have cleaned the tank and re-started the Steam Humidifier.
Note: The Cleaning Required LED turns on when the tank drains too slowly during a manual flush cycle, or after 1800 hours of operation (about 6 months).
(This is probably due to tank sediment.) The Steam Humidifier will still operate as normal. If during the next manual flush cycle, the tank drains normally, the
Cleaning Required light will stop blinking.
CAUTION: Scalding Hazard.
Initial water temperature may be above 140
the drain outlet is not exposed, and use caution when pressing the Drain button.

To initiate a flush cycle and empty the water tank,
press the Drain button and hold until the Draining LED
begins blinking.
Wait for the Empty light to turn on. (It takes about 45
minutes for the tank to drain.) This indicates that the
water has finished draining.
IMPORTANT: You can stop a manual flush once the
cycle has started by pressing and holding the Drain
button while the Draining light is already blinking. The
tank will refill and the Steam Humidifier will return to
normal operation in about 5 minutes.
Turn the manual shutoff valve at the tank bottom to the
"Unlock" position.
Grip the white water valve arm and push it back to
disconnect it from the tank.
