This unit is supplied with a portable
Ground Fault Circuit Interrupter (GFCI).
UL indicates that the power cord has been
investigated for compliance with the
applicable provisions of UL 943, Third
Edition (Standard for Ground Fault Circuit
Interrupters) and other applicable
standards. If power is interrupted in the
line, the GFCI will automatically reclose
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.
This Product Is
Double Insulated
In a double-insulated product, two
systems of insulation are provided instead
of grounding. No grounding method is
provided on a double-insulated product,
nor should a method for grounding be
added to the product. Servicing a doubleinsulated product requires extreme care
and knowledge of the system, and should
be done only by qualified service
personnel. Replacement parts for a
double-insulated product must be identical
to the parts they replace.
