Use a Surge Suppressor
Your treadmill, like other electronic equipment, can be
damaged by sudden voltage changes in your home’s
power. Voltage surges, spikes, and noise interfer-
ence can result from weather conditions or from other
appliances being turned on or off. To decrease the
risk of damaging the treadmill, always use a surge
suppressor with the treadmill. To purchase a surge
suppressor, see precaution 12 on page 3.
Use only a surge suppressor that is UL 1449 listed as a
transient voltage surge suppressor (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 also be electri-
cally rated for 120 volts AC and 15 amps. There must
be a monitoring light on the surge suppressor to indi-
cate whether it is functioning properly. Failure to use a
properly functioning surge suppressor could result
in damage to the control system of the treadmill
and serious injury to users.
Plug in the Power Cord
The treadmill must be grounded. If it should malfunc-
tion or break down, grounding provides a path of least
resistance for electric current to reduce the risk of elec-
tric shock. The treadmill power cord has a plug with a
grounding pin (see drawing 1 on this page).
Plug the power cord into a surge suppressor, and plug
the surge suppressor into an appropriate outlet that is
properly installed and grounded in accordance with all
local codes and ordinances. The outlet must be on a
nominal 120-volt circuit capable of carrying 15 or
more amps. To avoid overloading the circuit, do
not plug other electrical devices, except for low-
power devices such as cell phone chargers, into
the surge suppressor or into an outlet on the same
circuit. IMPORTANT: The treadmill is not compat-
ible with GFCI-equipped outlets and may not be
compatible with AFCI-equipped outlets.
A temporary
adapter may
be used to
connect the
surge sup-
pressor to
a 2-pole
if a properly
outlet is not
The lug or wire extending from the adapter must
be connected with a metal screw to a permanent
ground such as a properly grounded outlet box cover.
Some 2-pole receptacle outlet box covers are not
grounded. Before using an adapter, contact a quali-
fied electrician to determine whether the outlet box
cover is grounded. The temporary adapter should
be used only until a properly grounded outlet can
be installed by a qualified electrician.
DANGER: Improper connection
of the power cord increases the risk of elec-
tric shock. Do not modify the plug—if it will
not fit an outlet, have a proper outlet installed
by a qualified electrician. If you are unsure
whether the treadmill is properly grounded,
contact a qualified electrician.
