2) Attach the Grille onto the cabinet.
• Grasp lower the left and right side of the Grille
and engage four tabs on the top inside edge
of the chassis.
• Press the Grille toward the chassis until it will

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) See to 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) In a wet or moist area, always install an earth leakage circuit breaker.
8) The following would be caused by voltage 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.
