HOW TO PLUG IN THE POWER CORD

DANGER: Improper connec- tion of the equipment-grounding conductor increases the risk of electric shock. Check with a qualified electrician or serviceman if you are unsure whether the product is prop- erly grounded. Do not modify the plug—if it will not fit the outlet, have a proper outlet in- stalled by a qualified electrician.

Your treadmill, like other electronic equipment, can be damaged by sudden voltage changes in your home’s power. To decrease the risk of damaging your treadmill, always use a surge suppressor with your treadmill (see drawing 1 at the right). To purchase a surge suppressor, see precaution 12 on page 3.

Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge sup- pressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically rated for 120 volts AC and 15 amps. There must be a moni- toring light on the surge suppressor to indicate whether it is functioning properly. Failure to use a properly-functioning surge suppressor could dam- age the control system of the treadmill (see precau- tion 13 on page 3).

This product must be grounded. If it should mal- function or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product’s power cord has an equipment-grounding conductor and a grounding plug. Plug the power cord into a surge suppressor, and plug the surge suppressor into an appropri- ate outlet that is properly installed and grounded in accordance with all local codes and ordinances. IMPORTANT: The treadmill is not compatible with GFCI-equipped outlets and may not be compatible with AFCI-equipped outlets.

This product is for use on a nominal 120-volt circuit (see drawing 1). A temporary adapter may be used to connect the surge suppressor to a 2-pole receptacle if a properly-grounded outlet is not available (see drawing 2).

The temporary adapter should be used only until a properly-grounded outlet (see drawing 1) can be in- stalled by a qualified electrician.

The green-colored rigid ear, lug, or the like extend- ing from the adapter must be connected to a perma- nent ground such as a grounded outlet box cover. The adapter must be held in place by a metal screw.

Some 2-pole receptacle outlet box covers are not grounded. Contact a qualified electrician to deter- mine if the outlet box cover is grounded before using an adapter.
