HOW TO USE THE INCLINE TRAINER

HOW TO CONNECT THE POWER CORD

Use a Surge Suppressor

Your incline trainer, like other electronic equipment, 
can be damaged by sudden voltage changes in your 
home’s power. Voltage surges, spikes, and noise 
interference can result from weather conditions or from 
other appliances being turned on or off. 

To decrease 

the risk of damaging the incline trainer, always 
use a surge suppressor with the incline trainer. To 
purchase a surge suppressor, see precaution 14 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 incline 
trainer and serious injury to users.

Plug in the Power Cord

The incline trainer must be grounded. 

If it should 

malfunction or break down, grounding provides a path 
of least resistance for electric current to reduce the risk 
of electric shock. The incline trainer 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: If the incline trainer is con-
nected to an AFCI-equipped outlet and your circuit 
breaker trips repeatedly when the incline trainer is 
used, see the front cover of this manual to pur-
chase an arc filter.

A temporary 
adapter may 
be used to 
connect the 
surge sup-
pressor to 
a 2-pole 
receptacle 
if a properly 
grounded 
outlet is not 
available.

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 connec-

tion of the power cord increases the risk of 
electric 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 incline trainer is properly 
grounded, contact a qualified electrician.
