How
to
Install
the
Unit
To
prevent
vibration
and
noise,
make
sure
the
unit
is
installed
securely
and
firmly.
Install
the
unit
where
the
sunlight
does
not
shine
directly
on
the
unit.
The
outside
of
the
cabinet
must
extend
outward
for
at
least
12"
and
there
should
be
no
obstacles,
such
as a
fence
or
wall,
within
20"
from
the
back
of
the
cabinet
because
it
will
prevent
heat
radiation
of
the
condenser.
Restriction
of
outside
air
will
greatly
reduce
the
cooling
efficiency
of
the
air
conditioner.
CAUTION:
All
side
louvers
of
the
cabinet
must
remain
exposed
to
the
outside
of
the
structure.
Install
the
unit
a
little
slanted
so
the
back
is
slightly
lower than
the
front
(about
1/2").
This
will
force
condensed
water
to
flow
to
the
outside.
Install
the
unit
with
the
bottom
about
30"~60"
above
the
floor
level.

Electrical
Safety
IMPORTANT
(PLEASE
READ
CAREFULLY)
FOR
THE
USER'S
PERSONAL
SAFETY,
THIS
APPLIANCE
MUST
BE
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
(Fig.
12)
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
(Fig.
13).
The
large
slot
in
the
adapter
must
be
aligned
with
the
large
slot
in
the
receptacle
to
assure
a
proper
polarity
connection.
CAUTION:
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.

OF
EXTENSION
CORDS
Because
of
potential
safety
hazards,
we
strongly
discourage
the
use
of
an

Common
Problems
and
Solutions
Common
Issues
Before
calling
for
service,
please
review
the
following
list
of
common
problems
and
solutions.
The
air
conditioner
is
operating
normally
when:
?
You
hear
a
pinging
noise.
This
is
caused
by
water
being
picked
up
by
the
condenser
on
rainy
days
or
in
highly
humid
conditions.
This
feature
is
designed
to
help
remove
moisture
in
the
air
and
improve
cooling
efficiency.
?
You
hear
the
thermostat
click.
This
is
caused
by
the
compressor
cycle
starting
and
stopping.
?
You
see
water
dripping
from
the
rear
of
the
unit.
Water
may
be
collected
in
the
base
pan
in
highly
humid
conditions
or
on
rainy
days.
This
water
overflows
and
drips
from
the
rear
of
the
unit.
?
You
hear
the
fan
running
