Installation Instructions

ELECTRICAL WORK

Connect the cable to the outdoor unit

1. Remove the electrical control board cover from the outdoor unit by loosening the screw.

2. Connect the connective cables to the terminals as identified with their respective matched

numbers on the terminal block of indoor and outdoor units.

3. Secure the cable onto the control board with the cord clamp.

4. To prevent the ingress of water, from a loop of the connective cable as illustrated in the

installation diagram of indoor and outdoor units.

5. Insulate unused cords (conductors) with PVC-tape.Process them so they do not touch any

electrical or metal parts.

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.

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.
