D
Use a recogniz
ed circuit br
eaker 20A (
12K,18K),
25A (24K) bet
ween the pow
er source
and the unit. A disconnecting device t
o
adequately disconnect all supply lines must
be fitt
ed.
After the confirmation of the above conditions, prepare the wiring as follows:
Never
fail
to
have
an individual
power
circuit
specifically for
the air
conditioner. A
s for
the method
of wiring,
be
guided by
the cir

ed on
the inside
of contr

cover
.
The scr

en the wiring
in the
casing of
electrical fittings ar
e liable
to
come
loose from vibr
ations to which
the unit
is subject
ed during
the course
of
transportation.
Check
them and
make sur
e that
they ar
e all
tightly fast
ened. (If
they
are
loose, it
may cause
burn-out of
the wires.

sufficient.
The starting v

maintained at
more
than 90
percent
of the
rat

marked
on the

e.
Confirm that
the cable
thickness is
as specified
in the
power
source
specification.
(Particularly not
