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.
