Here is some information you may need when setting up a new salon, or adding additional units to your existing salon. Below you will find Contractor Spec Sheets, which are intended to give a contractor everything they need to know to make a room ready to accept a specific tanning unit. ETL Certification Letters are for any inspectors that need proof that the tanning units are certified to UL standards prior to approving a salon set-up. Each unit is marked with this certification but you may need this before the unit arrives.
