Connect the cable to the

outdoor unit

Remove the control cover from the unit by

loosening the screw.

Connect the wires to the terminals on the

control board individually.

Secure the cable onto the control board

with the cord clamp.

Refix the control cover to the original

position with the screw.

Use a recognized circuit breaker 20A(18K),

25A(24K, 26K) between the power source

and the unit. A disconnecting device to

adequately disconnect all supply lines

must be fitted.

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. (Refer to page 11))

7) Always install an earth leakage 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, 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.
