NOTICE

10 Room Air Conditioner
Electrical
Safety
IMPORTANT
(PLEASE
READ
CAREFULLY)
FOR THE USER'S PERSONAL
SAFETY,
THIS
APPLIANCE MUSTBE PROPERLY GROUNDED
The
power
cord of this
appliance
is
equipped
with a
three-prong (grounding) plug.
Use this with a standard
three-slot
(grounding)
wall
power
outlet to minimize the
hazard of electric shock. The customer should have
the wall
receptacle
and circuit checked
by
a
qualified
electrician to make sure the
receptacle
is
properly
grounded.
DO NOT CUT OR REMOVE THE THIRD
(GROUND)
PRONG FROM THE POWER PLUG.
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.

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
