Installation
CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. 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 fastened. (If they
are loose, it could cause burn-out of the wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) Confirm that the starting voltage is maintained 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 specification.
(Particularly note the relation between cable length and thickness.
7) Always install an GFCI circuit breaker in a wet or moist area.
8) The following would be caused by voltage drop.
• Vibration of a magnetic switch, which will damage the contact point, open fuse, 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(0.12in) in each
active(phase) conductors.
