Use
this
with
a
standard
three-slot

to
minimize
the
hazard
of

The
customer
should

to
make
sure
the

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
wall
receptacle
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
(grounding)
outlet
instead.
USE
OF
EXTENSION
CORDS
Because
of
potential
safety
hazards,
we
strongly
discourage
the
use
of
an
extension
cord.
However,
if
you
wish
to
use
an
extension
cord,
use a
CSA
certified/UL-listed
3-wire
(grounding)
extension
cord,
rated
at
15A,
125V.

HOW
TO
INSTALL
Identify
the
existing
wall
sleeve
before
installing
the
unit
from
the
listed
below.
All
wall
sleeves
used
to
mount
the
new
Air
Conditioner
must
be
in
sound
structural
condition
and
have
a
rear
grille
that
securely
attaches
to
sleeve,
or
rear
flange
that
serves
as
a
stop
for
the
Air
Conditioner,
Remove
old
air
conditioner
from
existing
wall
sleeve.
Clean
the
interior
of
an
existing
sleeve.
(Do
not
disturb
seals.)
Wall
sleeve
must
be
securely
fastened
in
wall
before
installing
the
air
conditioner.
Use
the
nails
or
screws
through
sleeve
into
wall,
if
needed.
Repaint
sleeve
if
needed.
Prepare
the
wall
sleeve
for
installation
of
the
unit.
If
you
plan
to
use
your
existing
wall
sleeve,
and
it
is
not
LGE,
use
procedure
B
or
C
below.
Install
new
unit into
wall
sleeve.
When
installation
is
completed,
replacement
unit
MUST
have
a
rearward
slope
as
shown.
To
achieve
1.4"
slope,
remove
the
backing
from
the
11-13/16"
shim
strips
and
attach
them
as
shown
below
in
Fig.

We
strongly
recommend
the
removal
of
the
old

If
you
decide
to
keep
the
existing

you
have
to
redirect
the
louvers
at
the
back
of
the
wall
sleeve
illustration.
The
use
of
pliers
is
recommended.
If
you
DO
NOT
redirect,
you
run
the
risk
of
poor
performance
or
product
failure.

The
air
filter
should
be
checked
at
least
twice
a
month
to
see
if
cleaning
is
necessary.
Trapped
particles
in
the
filter
will
build
up
and
block
the
airflow.
This
reduces
the
cooling
capacity
and
also
causes
an
accumulation
of
frost
on
the
cooling
coils.
If
the
filter
becomes
worn
or
damaged
you
should
replace
immediately.
Replacement
filters
are
available
from
your
salesperson,
dealer,
and
the
authorized
customer
service
centers.
