2.1.1
Placement
considerations
Placement
of
outdoor
units
should
take
account
of
the
following
considerations:
Air
conditioners
should
not
be
exposed
to
direct
radiation
from
a
high
‐
temperature
heat
source.
Air
conditioners
should
not
be
installed
in
positions
where
dust
or
dirt
may
affect
heat
exchangers.
Air
conditioners
should
not
be
installed
in
locations
where
exposure
to
oil
or
to
corrosive
or
harmful
gases,
such
as
acidic
or
alkaline
gases,
may
occur.
Air
conditioners
should
not
be
installed
in
locations
where
exposure
to
salinity
may
occur
unless
the
anti
‐
corrosion
treatment
for
high
‐
salinity
areas
customization
option
has
been
added
and
the
precautions
described
in
Installation
Manual,
10
“Installation
in
Areas
of
High
Salinity”
are
taken.
Outdoor
units
should
be
installed
in
well
‐
drained,
well
‐
ventilated
positions
that
are
as
close
as
possible
to
the
indoor
units.
2.1.2
Spacing
Outdoor
units
must
be
spaced
such
that
sufficient
air
may
flow
through
each
unit.
Sufficient
airflow
across
heat
exchangers
is
essential
for
outdoor
units
to
function
properly.
Figures
3
‐
2.1
to
3
‐
2.3
show
spacing
requirements
in
three
different
scenarios.
If
the
particular
circumstances
of
an
installation
require
a
unit
to
be
placed
closer
to
a
wall
than
specified
in
Figures
3
‐
2.1
to
3
‐
2.3,
a
discharge
duct
should
be
installed.
Refer
to
Installation
Manual,
3
“Outdoor
Unit
Ducting
and
Shielding”.
Depending
on
the
height
of
adjacent
walls
relative
to
the
height
of
the
units,
ducting
may
be
required.
Refer
to
Installation
Manual,
3
“Outdoor
Unit
Ducting
and
Shielding”.
