place
in
consideration
of
following
conditions.
•
A
place
where
it
is
horizontal,
stable
and
can
endure
the
unit
weight
and
will
not
allow
vibration
transmittance
of
the
unit.
•
A
place
where
it
can
be
free
from
possibility
of
bothering
neighbors
due
to
noise
or

from
the
unit.
•
A
place
where
the
unit
is
not
exposed

•
A
place
where
it
can
be
free
from
danger
of
flammable
gas
leakage.
•
A
place
where
drain
water
can
be
disposed
without
any
trouble.
•
A
place
where
the

will
not
be
affected
by
heat
radiation
from
other
heat
source.
•
A
place
where
snow
will
not
accumulate.
•
A
place
where
the
unit
can
be
kept
away
5m

radio
receiver
in
order
to
avoid
any
radio
or
TV
interference.
•
A
place
where
good
air
circulation
can
be
secured,
and
enough
service
space
can
be
secured
for
maintenance
and
service
of
the
unit
safely.
•
A
place
where
the
unit
will
not
be
affected
by
electromagnetic
waves
and/or
high-harmonic
waves
generated
by
other
equipment.
•
A
place
where
chemical
substances
like
sulfuric
gas,
chloric
gas,
acid
and
alkali
(including
ammonia),
which
can
harm
the
unit,
will
not
be
generated
and
not
remain.
•
If
a
operation
is
conducted
when
the
outdoor
air
temperature
is
-5
lower,
the
outdoor
unit
should
be
installed
at
a
place
where
it
is
not
influenced
by
natural
wind.
•
A
place
where
strong
wind
will
not
blow
against
the
outlet
air
blow
of
the
unit.
4) Caution about selection of installation location
•
Walls surrounding the unit in the four sides are not acceptable.
•
There must be a 1-meter or larger space in the above.
•
When more than one unit are installed side by side, provide a 250mm or wider interval between them as a service space. In order to facilitate servicing of controllers, please provide a sufficient space between units so that their top plates can be removed easily.
•
Where a danger of short-circuiting exists, install guide louvers.
•
When more than one unit are installed, provide sufficient intake space consciously so that short-circuiting may not occur.
•
Where piling snow can bury the outdoor unit, provide proper snow guards.
