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) 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.
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.)
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) See to 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.

1) Checking the Drainage
1. Remove the Grille from the cabinet
• Set the up-and-down air direction louver to
open position(horizontally) by finger pressure.
• Remove the securing screws.
• To remove the Grille, pull lower the left and
right side of the grille toward you (slightly tilted)
and lift it straight upward.
