How to Drain the Humidifier 

1.

 

This procedure drains the water in the humidifier only, not the water recirculation system. 

2.

 

Wait at least 1 hour 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. 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.

Warning

 – will 

be very hot during humidity 

system operation and can 

cause burns if touched!
