F. Water Drain Line
This 1/2-inch hose drains water from the Steam
Humidifier to a drain in your home. The tank is
drained automatically when the Steam Humidifier
performs an automatic flush cycle, and at the end
of the humidification season. You may also drain the
tank manually in order to clean the tank or perform
additional maintenance.
G. Safety Release Button
This button prevents the tank release lever from
accidentally moving forward and releasing the water
tank. Press and hold the button down to move the
lever forward.
H. Ventilation Holes
These holes provide airflow for the electronic
components inside the Steam Humidifier cover.
Normal maintenance includes keeping these holes
clean.
I. Steam Humidifier Cover
The Steam Humidifier wiring connections and
electronic components are located behind the cover.
There are no homeowner-serviceable parts here,
and the cover should only be removed by a qualified
HVAC Service Technician.
J. Tank Release Lever
This lever locks the water tank in place on the
Steam Humidifier. Press the safety release button,
then pull the lever forward to release the water tank
when removing for cleaning or service.
IMPORTANT: Only remove the tank after it is
completely empty. See "How do I clean the tank?"
on page 16.
Steam Humidification System 69-2286EF—07
K. Light Display
The six lights are on or blinking to indicate the
Steam Humidifier's operational status and when
service is required. See "What do the lights tell me?"
on page 13.
L. Steam Humidifier Buttons
The two buttons are the only controls located on
the Steam Humidifier. They are seldom used by the
homeowner. (Remember, day-to-day operation is
done using your humidity control.) Use the Drain
button to manually drain the water tank. Use the Go
button to reset the Steam Humidifier when restarting
the system. See "When will I press the Drain and Go
buttons?" on page 14.
M. Water Tank
The tank holds the water that the Steam Humidifier
heats and converts to steam. The tank can be
removed for cleaning.
N. Manual Shutoff Valve
Turn this valve by hand to either of two positions:
Lock: The valve will be locked during operation. This
turns the water supply on and locks the solenoid
valve in place. (The Steam Humidifier uses the
solenoid valve to control water flow into the tank.)
Unlock: Turning the valve to "Unlock" seals the
bottom of the tank and the water supply to avoid
leaks when performing manual cleaning of the tank.
It also disengages the solenoid valve so that you
can push the solenoid back in its base to release
the tank. Once this is done, you can pull the tank
release lever forward to remove the tank
for cleaning. See "How do I clean the tank?" on page
16 .
