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.
Teach the customer the operation and maintenance procedures, using the operation manual (air filter cleaning,
temperature control, etc.).
