conditioner
trouble
is
liable
to
occur.
• Where flammable gas could leak
•
Where
there
is
much
machine
oil.
• Where oil is splashed or where the area is
fi
lled with oily smoke (such
as
cooking
areas
and
factories,
in
which
the
properties
of
plastic
could
be
changed
and
damaged).
•
Salty
places
such
as
the
seaside.
• Where sulfide gas is generated such as a hot spring
•
Where
there
is
high-frequency
