How to Drain the Humidity System
1. This procedure drains the water in the humidifier only, not the water recirculation system.
2. Wait at least 2 hours after running a humidity test before draining the system.
3. Disconnect the chamber from the power source.
4. Remove the lower rear panel.
5. Open the Drain Valve by turning its handle 90 degrees counter-clockwise (as if you were
facing the front of the valve handle). Water will come out of the Drain fitting on the back of
the chamber.
6. After the system is drained, close the Drain Valve by turning its handle 90 degrees clockwise
(as if you were facing the front of the valve handle).
