When installation is complete, plug steam humidifier in and turn the humidity control on. Make sure it is running
properly before turning the system over to the homeowner. Once steam humidifier is running, day-to-day operation
is hands-free, except for occasional cleaning. The homeowner can use the control to adjust the humidity setpoint,
adjust the frost setting (if used), or turn steam humidifier off as desired.
Slide the cover into place and secure with the
cover screw.
Turn on the water supply at all valves. Cold water will
flow to the steam humidifier but will not fill the tank
until the unit is turned on and a call for humidity is
made.
Plug in the steam humidifier power cord.
•
The Power light will turn on, indicating that steam
humidifier has power.
Turn the humidity control to On.
• The Humidifying light will start blinking. This means
steam humidifier is in Stand-by.
Press/release the Go button to prepare steam
humidifier for use. Steam humidifier will automatically
reset if the Go button is not pressed after 5 minutes.

The tank will fill with cold water and the humidifier
light will be blinking. Water flow stops automatically
when the tank is full.
• The Humidifying light will be solidly on — it will stop
blinking — when steam humidifier is heating water
for steam production.
Wait until steam humidifier produces steam, then
check the following:
•
Make sure air is blowing from furnace. Typically, the
blower turns on 10 –15 minutes after the call for
humidity if steam humidifier is controlling the fan.
• Check all water line connections to ensure there
are no leaks before leaving the job site.
• Turn the setpoint to the desired level when testing
is complete. If humidity is not needed, set the
control to Off.
