CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner. As for the method
of wiring, be guided by the circuit diagram pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) 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 fastened. (If they are loose, it could give
rise to burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking,
disturbance to the normal function of a overload protection device.
• Proper starting power is not given to the compressor.
10) Appliance mst be grounded.
• To minimize the risk of electric shock, you must always plug into a grounded outlet.
• Do not cut or remove the grounding.

6. Connecting Cables between Indoor and Outdoor Unit
1) Connecting cables to the Indoor Unit
Connect the wires to the terminals on the control board individually according to the
outdoor unit connection.
• Ensure that the color of the wires of outdoor unit and the terminal No. are the same as
those of indoor unit respectively.
Please do the interconnection as per Interconnection Table in wiring diagram.
CAUTION
The power cord connected to the outdoor unit should be
with the following specifications
The connecting cable connected to the indoor and outdoor
unit should be with the following specifications

6) Pipe bending
Annealed copper pipe with small diameter (ø6.35 or ø9.52) can be easily bent manually. In
this case, secure large R(radius) for the bend section and gradually bend pipe. If annealed
copper pipe is large in diameter (ø12.7, ø15.88 or ø19.05), bend pipe with bender. Use bender
appropriate for the pipe diameter.
7) Brazing
In refrigerant piping, bending (in particular, acute bending) must be minimized to reduce
piping resistance. Bending is, however, necessary in some places by virtue of the installation
position of devices or of the building structure, piping distance or finishing appearance.
Perform brazing using ready-made elbow. Aside from this function, brazing
perform brazing using ready-made elbow. Aside from this function, brazing
also serves to connect straight pipes, generally using ready-made sockets. While brazing,
protect piping against heat with wet cloth to avoid damaging valve packing or burning
thermal insulator with burner heat. While brazing, blow inert gas (nitrogen gas or carbonic
gas) to prevent formation of oxidation film in copper piping; otherwise, the refrigerant circuit
will clog. The blowing of nitrogen gas (or carbonic gas) through 3-way valves is described in
the following:
8) Refrigerant piping(Flare piping)
When connecting piping, be sure to keep piping dry(keep piping away from water), clean
(keep piping away from dust) and airtight (avoid refrigerant leakage).
When connecting piping on rainy days or making a through-hole in wall, take due care to
prevent water or plaster from entering piping.
Water enters
Plaster enters
CAUTION
a. This procedure is designed to prevent formation of oxidation film by filling piping with
inert gas. Note that excessive gas pressure will generate pinholes at brazed points.
(Nitrogen gas: Supply pressure
0.05~0.1kg/cm2G)
b. When supplying inert gas, be sure to open one end of piping.
