INTERRUPTION:
HF12-1200U:
The
outlets
on the front
panel-are
equipped
with
an integral
ground
fault
circuit
intenupter
(GFCI).
In
the
case
of
a
giould

ttiii
device
will
ind,'up't
the

of the
Heart,
and
the reser

will
pop-out.
To
resei,
push
the
uurio"

in.
On the
GFCI there
are
two
buttons,
the
reset
and
the
test
button.
Monthly
you

If it
does not pop
out,
you
must

Important
note:
The
GFCI
test will
not
work properly
if
the
unit
is in
idle.
you
must put
a load
on
the
unit
to
perform
the
monthly
test.
