POWER REQUIREMENTS
Power Requirements:
IMPROPER CONNECTION OF THE EQUIPMENT GROUNDING CONNECTOR CAN RESULT IN A RISK OF AN
ELECTRIC SHOCK. CHECK WITH A QUALIFIED ELECTRICIAN OR SERVICE MAN IF YOU ARE IN DOUBT AS TO
WHETHER THE PRODUCT IS PROPERLY GROUNDED. DO NOT MODIFY THE PLUG PROVIDED WITH THE
PRODUCT, IF IT WILL NOT FIT THE OUTLET; HAVE A PROPER OUTLET INSTALLED BY A QUALIFIED ELECTRICIAN.
This treadmill can be seriously damaged by sudden voltage changes in your home’s electrical power. Voltage spikes, surges
and noise interference can result from weather conditions or from other appliances being turned on or off. To reduce the
possibility of treadmill damage, always use a surge protector (not included) with your treadmill.
Surge protectors can be purchased at most hardware stores. The manufacturer recommends a singleoutlet surge protector
with a UL 1449 rating as a Transient Voltage Surge Suppressor (TVSS) with a UL suppressed voltage rating of 400V or less
and an electrical rating 120VAC, 15 amps.
This treadmill must be grounded to reduce the risk of electrical shock. Grounding provides a path of least resistance for
electric current, should the treadmill malfunction. This treadmill comes with an electrical cord having an equipment-grounding
conductor and a grounding plug. Always plug the power cord into a surge protector, and plug the surge protector into an
appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
This product is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in the
drawing below.
