CAUTION: Risk of contact with hot surfaces. Can cause burn injury. The EC fans, electronics
housing, humidifier pan and water contained within are extremely hot during operation. Allow

on the EC fans.
To replace the fan(s):
1. Turn off the unit by touching "Turn Unit Off" in the iCOM menu and confirm in next screen by
touching "Turn Unit Off."
2. Allow the unit shut down. Once shutdown is complete, turn the disconnect switch to the Off
position.
3. Open the front of the unit.
4. Remove the humidifier drain line by removing it from the T-connection on the left side of the
unit and disconnecting it from the humidifier pan. Then pull it up through the humidifier
air-blocking panel it passes through. See Figure 9.2 on the facing page.
