• Dimensions: 11-1/4 in. W x 19 in. H x 9 in. D
• Humidifier Operating Temperature Range:
34ºF–104ºF (1.1ºC–40ºC)
• 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 8, 12, 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
DRAIN button) initial water temperature may be
above 140ºF (60ºC). Ensure drain outlet is not
exposed and use caution when pressing the DRAIN
button, and do NOT attempt to remove the tank with
water in it.
• Flush cycle takes approximately 45 minutes to empty
the tank completely.
• Draining Temperature Range: 34ºF–212ºF
(1.1ºC–100ºC)
