GROUNDING INSTRUCTIONS

This product must be grounded. If it should 
malfunction or breakdown, grounding 
provides a path of least resistance for electric 
current to reduce the risk of electric shock. 
This product is equipped with a cord having 
an equipment-grounding conductor and a 
grounding plug. The plug must be plugged 
into an appropriate outlet that is properly 
installed and grounded in accordance with all 
local codes and ordinances.

DANGER

Improper connection of the equipment-
grounding conductor can result in a risk of 
electrocution. Check with a qualified 
electrician or service personnel if you are in 
doubt as to whether the outlet 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. Do not use any type of adapter 
with this product.

GROUND FAULT CIRCUIT 
INTERRUPTER PROTECTION

This product is supplied with a Ground Fault 
Circuit Interrupter (GFCI) built into the power 
cord plug. This device provides additional 
protection from the risk of electric shock. If 
power is interrupted in the line, the GFCI will 
automatically re-close the circuit to the load 
after power is restored. Depending on the 
GFCI model, it may be necessary to manually 
operate the reset button to restore power to 
the GFCI load circuit. If replacement of the 
plug or cord is needed use identical 
replacement parts.
