User manuals for Sunbeam humidifiers can be downloaded from the support page of the manufacturer. It is easiest to find the manual if the model number is known. On current models, this number starts with 00, SCM, SWM or SUM.
The manuals for models not listed on the main humidifier support page can be searched by entering the model number in the search box on the top right-hand side of the support page. The manuals are in PDF format, and they consist of simple usage instructions and trouble-shooting tips. Third-party websites also have Sunbeam humidifier manuals and quick-start guides available for download.
