When installation is complete, follow the steps below. Make sure the humidifier is running properly before turning
the system over to the homeowner. Once the humidifier is running, day-to-day operation is automatic. The
homeowner can use the control to adjust the humidity levels and turn the humidifier on or off.
Snap the bottom cover into place.
Turn on the water supply at the saddle valve or
T-fitting and manual shutoff valve. Water will flow to the
humidifier but will not pass through the pad until the
humidity control is turned on.
Plug in the humidifier (HE300) or apply HVAC system
power (HE100/HE150/HE200/HE250)
On advanced models, the LED lights will blink for
•
3-5 seconds to verify that there is system power.
On HE100/HE200, turn the Damper Position knob on
the bypass outlet so that it is parallel to the bypass
outlet. On HE150/HE250, the humidifier does this
automatically. Not applicable for HE300.
Turn the humidity control to On.
If your wiring is configured for operation only with
•
heat or fan, make the appropriate system demands
to allow humidification.
Make sure air is blowing through the ductwork with
•
the humidifier call.
The Humidifying light will be solidly on when water is
flowing through the humidifier pad
On HE150/HE250 models, remove the humidifier’s
•
top cover to verify water flow through the top tray
and into the pad. Make sure that the damper
rotates open when humidity is on, and rotates
closed when humidity is off.
On HE300 models, verify water is exiting the drain
•
hose.

Startup and Checkout
Check all water line and drain connections to ensure there are no leaks before leaving the job site.
Check for leaks immediately after turning the main water supply on, and again after 15 minutes of humidifier
•
operation.
Turn the setpoint to the homeowner’s desired level when testing is complete. If humidity is not needed, set the
control to Off, and turn the Damper Position knob on the bypass outlet so that it is perpendicular to the bypass
outlet (HE100/HE200 only).
