15. Installation

3)Connecting the cable to Outdoor Unit

1.Remove the control cover from the unit by loosening a screw.

Connect the wires to the terminals on the control board individually as specified.

2.Secure the cable onto the control board with the hold- er (clamper).

3.Refix the cover control to the original position with the screw.

4.Use a recongnized circuit breaker 20A(18k, 24k) between the power source and the unit. A disconnec- tion 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 specially for the air conditioner. Guidence for wiring is in the circuit diagram which is 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 become loose due to vibrations, to which the unit is subjected during the course of transportation. Check them and make sure that they all are tightly fastened. (If they are loose, it could burn-out the wires.)

4)Confirm specification of power source.

5)Confirm 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 the cable thickness should be proper 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.

10)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.
