How
to
Install
the
Unit
1.
To
prevent
vibration
and
noise,
make
sure
the
unit
is
installed
securely
and
firmly
2.
Install
the
unit
where
the
sunlight
does
not
shine
directly
on
the
unit.
3.
The
outside
of
the
cabinet
must
extend
outward
for
at
least
14"
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.
All
side
louvers
of
the
cabinet
must
remain
exposed
to
the
outside
of
the
structure.
4.
Install
the
unit
at
a
slight
incline
so
the
back
is
slightly
lower
than
the
front(about
1/4").
This
will
force
condensed
water
to
flow
to
the
outside.
5.
Install
the
unit
with
the
bottom
about
30"~60"
above
the
floor
level.
