●
With tape material along the wire wrapped, sealed wiring holes, prevent the condensed water and insects.
●
Tightly
secure
the
power
source
wiring using
the
cord
clamp
inside
the
unit
.
NOTE
:
Fix
the
rubber
bushes
with
adhesive
when conduit
tubes
to
the
outdoor
unit
are
not
used
.
General
Check
(1)
Make
sure
that
the
field
-
selected
electrical components
(
main
power
switches
,
circuit breakers
,
wires
,
conduit
connectors
and
wire
terminals
)
have
been
properly selected
according
to
the
electrical
data
.
Make
sure
that
the
components
comply with
National
Electrical
Code
(
NEC
).
(2)
Check
to
ensure
that
the
voltage
of
power supply
is
within
+
10
%
of
nominal
voltage and
earth
phase
is
contained
in
the
power
supply
wires
.
If
not
,
electrical
parts
will
be damaged
.
(3)
Check
to
ensure
that
the
capacity
of
power supply
is
enough
.
If
not
,
the
compressor
will
not be
able
to operate
cause
of
voltage
drop
abnormally at
starting
.
(4)
Check
to
ensure
that
the
earth
wire
is connected
.
(5)
Install
a
main
switch
,
multi
-
pole
main
switch
with
a
space
of
3
.
5mm
or
more, single phase
main
switch
with
a
space
of
3
.
0mm
or
more
between
each
phase
.
Please use the special three-phase power switch for 3-Phase product.
(6) Check
to
ensure
that
the
electrical resistance
is
more
than
2M
Ω,
by measuring
the
resistance
between
ground and
the
terminal
of
the
electrical
parts
.
If
not
,
do
not
operate
the
system
until
the electrical
leakage
is
found
and
repaired
.
●
Turn
OFF
the
main
power
switch
to
the
indoor
unit
and
the
outdoor
unit
and
wait
for more
than
3
minutes
before
electrical
wiring work
or
a
periodical
check
is
performed
.
●
Check
to
ensure
that
the
indoor
fan
and
the outdoor
fan
have
stopped
before
electrical
wiring
work
or
a
periodical
check
is performed
.
●
Protect
the
wires
,
electrical
parts
,
etc
.
from rats
or
other
small
animals
.
If
not
protected
,
rats
may
gnaw
at
unprotected
parts
and
at
the worst
,
a
fire will
occur
.
●
Avoid
the
wiring
from
touching
the
refrigerant
pipes
,
plate
edges
and
electrical parts
inside
the
unit
.
If
not
do
,
the
wires
will
be
damaged
and
at the
worst
,
a
fire
will
occur
.
●
Install
an
ELB
(Electric Leakage Break) in
the
power
source
.
If
ELB
is
not
used
,
it
will
cause
electric
shock
or fire
at
the
worst
.
●
This
unit
uses
an
inverter
,
which
means
that
it
must
be
used
an
earth
leak
detector
capable
handing
harmonics
in
order
to
prevent
malfunctioning
of
the
earth
leak
detector
itself.
●
Do not use intermediate connection wires, stranded wires(see <Attentions
when
Connect the power supply wiring>),
extension cables or control line connection, because the use of these wires may
cause fever, electric shock or fire.
●
The
tightening
