14. Installation

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. For wiring, methed take guidance from the circuit diagram posted on the inside of control cover.

2.Firmly tighten the terminal screws to prevent them loosening. After tightening, pull the wires lightly to confirm that they do not move. (If they are loose the unit will not operate normally or it can cause burn-out of the wires.)

3.Check 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.An earth leakage circuit breaker should be equiped 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.
