• Dimensions: 11-1/4 in. W x 19 in. H x 9 in. D
• Humidifier Operating Temperature Range: 34ºF–
120ºF (1.1ºC–49ºC)
• Remote Hose/Nozzle Operating Temperature Range:
-50ºF–250ºF (-46ºC–121ºC)
• Operating Humidity Range: 0–95% RH, non-
condensing
Drain Operation
• Auto flushing is configurable to 10, 20 or 30 hours of
operational time (heating element active).
• During auto flushing, cold water will enter the tank to
lower water temperature below 140ºF (60ºC) before
draining.
• During manual flush (performed by pressing the
EMPTY button) initial water temperature may be
above 140ºF (60ºC). Ensure drain outlet is not
exposed and use caution when pressing the EMPTY
button, and do NOT attempt to remove the tank with
water in it.
• Flush cycle takes approximately 15 minutes to
empty the tank completely. To override, press/hold
the EMPTY button while the “Clean Tank” light is
blinking.
• Drain Hose Operating Temperature Range: 34ºF–
212ºF (1.1ºC–100ºC)
