service hints
Frequently what seems to be a major problem can be solved very easily. Listed below are the common concerns with any humidifier.
Check the sinple things first. Remove the front panel and see if there is a crusty, white lime build-up on the media pad. The lime build­
up won’t hurt the humidifier, but will reduce its output. Low output might just mean your humidifier needs cleaning.
