What type of surge suppressor do I need to use with the treadmill?

You must use a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge suppressor (TVSS), with a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. It must be electrically rated for 120 volts AC and 15 amps, and must have a monitoring light to indicate whether it is functioning properly. Failure to use a properly functioning surge suppressor could damage the control system, potentially causing the walking belt to change speed, accelerate, or stop unexpectedly. You can order a compatible surge suppressor by calling 1-866-699-3756 and requesting part number 146148.
