- Connect the wires to the terminals on the
control board individually.
- Secure the cable onto the control board with
the cord clamp.
- Use a recognized circuit breaker between
the power source and the unit.
A disconnecting device to adequately discon-
nect all supply lines must be fitted.
- Provide a circuit breaker between power
source and the outdoor unit as shown below.

When using the separate wire as the
power cord, please fix the separate wire
into the control box panel by using tie wrap
as the fixture. "A" & "B" are minimum rec-
ommended wire size.

CAUTION
!
According to the confirmation of the above
conditions, prepare the wiring as follows.
1
Never fail to have an individual power
circuit specifically for the air condi-
tioner. As for the method of wiring, be
guided by the circuit diagram posted
on the inside of control cover.
2
The screw which fasten the wiring in
the casing of electrical fittings are liable
to come loose from vibrations to which
the unit is subjected during the course
of transportation. Check them and
make sure that they are all tightly fas-
tened. (If they are loose, it could cause
burn-out of the wires.)
3
Specification of power source.
4
Confirm that electrical capacity is suffi-
cient.
5
See that the starting voltage is main-
tained at more than 90 percent of the
rated voltage marked on the name
plate.
6
Confirm that the cable thickness is as
specified in the power source specifi-
cation.
(Particularly note the relation between
cable length and thickness.
7
Always install an earth leakage circuit
breaker in a wet or moist area.
8
The following would be caused by volt-
age drop.
- Vibration of a magnetic switch, which
will damage the contact point, fuse
breaking, disturbance of the normal
function of the overload.
9
The means for disconnection from a
power supply shall be incorporated in
the fixed wiring and have an air gap
contact separation of at least 3mm in
each active(phase) conductors.
