A.
SITUATIONS
WHEN
THE
APPLIANCE
WILL
BE
DISCONNECTED
OCCASIONALLY:
Because
of
potential
safety
hazards,
we
strongly
discourage
the
use
of
an
adapter
plug.
However,
if
you
wish
to
use
an
adapter,
a
TEMPORARY
CONNECTION
may
be
made.
Use
UL-listed
adapter,
available
from
most
local
hardware
stores.
The
large
slot
in
the
adapter
must
be
aligned
with
the
large
slot
in
the
receptacle
to
assure
a
proper
polarity
connection.
:
Attaching
the
adapter
ground
terminal
to
the
wall
receptacle
cover
screw
does
not
ground
the
appliance
unless
the
cover
screw
is
metal,
and
not
insulated,
and
the

is
grounded
through
the
house
wiring.
The
customer
should
have
the
circuit
checked
by
a
qualified
electrician
to
make
sure
the
receptacle
is
properly
grounded.
Disconnect
the
power
cord
from
the
adapter,
using
one
hand
on
each.
Otherwise,
the
adapter
ground
terminal
might
break.
DO
NOT
USE
the
appliance
with
a
broken
adapter
plug.
B.
SITUATIONS
WHEN
THE
APPLIANCE
WILL
BE
DISCONNECTED
OFTEN.
Do
not
use
an
adapter
plug
in
these
situations.
Unplugging
the
power
cord
frequently
can
lead
to
an
eventual
breakage
of
the
ground
terminal.
The
wall
power
outlet
should
be
replaced
by
a
three-slot

outlet
instead.
USE
OF
EXTENSION
CORDS
Because
of
potential
safety
hazards,
we
strongly
discourage
the
use
of
an
extension

However,
if
you
wish
to
use
an
extension
