OPERATION AND ADJUSTMENT
HOW TO PLUG IN THE POWER CORD
Your treadmill, like other electronic equipment, can be
damaged by sudden voltage changes in your homeʼs
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 malfunc-
tion or break down, grounding provides a path of least
resistance for electric current to reduce the risk of elec-
tric shock. This productʼs power cord has an equip-
ment-grounding conductor and a grounding plug.
Plug
the power cord into a surge suppressor, and plug
the surge suppressor into an appropriate outlet
that is properly installed and grounded in accor-
dance 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 extending
from the adapter must be connected to a permanent
ground such as a properly-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.
DANGER:
Improper connection
of the equipment-grounding conductor in-
creases the risk of electric shock. Check with
a qualified electrician or serviceman if you
are unsure whether the product is properly
grounded. Do not modify the plug—if it will
not fit the outlet, have a proper outlet in-
stalled by a qualified electrician.
