This is a detailed, 50 page manual including troubleshooting flowcharts, schematics, parts diagrams and disassembly instructions so you can troubleshoot, repair and maintain your ESB brand tanning bed like a pro! Featuring electrical requirements, info. on buck boosters, FAQ's, ballast/lamp technical info., amperages, specifications, lamp configurations, plus a lot more! This was issued around 2006 - not that the beds have changed much since then. For years, this was a dealer-only item...now, available to the end user!
