have
an
Authorized
Servicer
install
an
exact
replacement
part.
1.
Being
exposed
to
direct
airflow
for
an
extended
period
of
time
could
be
hazardous
to
your
health.
Do
not
expose
occupants,
pets,
or
plants
to
direct
airflow
for
extended
periods
of
time.
2.
Due
to
the
possibility
of

ventilate
the
room
when
used
together
with
stoves
or
other
heating
devices.
3.
Do
not
use
this

could
damage
the
items.
4.
The
air
conditioner

replace
the
outlet
before
you
use
the
room

Changing
the
outlet
without
making
the
appropriate
wiring
changes
will
create
an
unsafe
condition
that
could
result
in
fire
or
electrical
shock.
Refer
all
such
work
to
a
licensed
and
qualified
electrician.
WARNING:
Do
not cut

remove
the
grounding
prong
from
the
power
plug.
WARNING:

to
the
wall
receptacle
cover
screw
does
not

Room
Air
Conditioner
We
strongly
discourage
the
use
of
an
adapter
due
to
potential
safety
hazards.
For
temporary
connections,
use
only
a
UL-listed
adapter,
available
from
most
local
hardware
stores.
Ensure
that
the
large
slot
in
the
adapter
is
aligned
with
the
large
slot
in
the
receptacle
for
a
proper
polarity
connection.
To
disconnect
the
power
cord
from
the
adapter,
use
one
hand
on
each
to
avoid
damaging
the
ground
terminal.
Avoid
frequently
unplugging
the
power
cord
as
this
can
lead
to
eventual
ground
terminal
damage.
WARNING:
Never
use
the
appliance
with
a
broken
adapter.
We
strongly
discourage
the
use
of
an
extension cord
due
to
potential
safety
hazards.
For
temporary
situations,
use
