CAUTION
1. The air conditioner should use separate power supply with rated voltage.
2. The external power supply to the air conditioner should have ground wiring, which is linked to the
ground wiring of the indoor and outdoor unit.
3. The wiring work should be done by qualified persons according to circuit drawing.
4. A disconnection device having an air gap contact separation in all active conductors should
incorporated in the fixed wiring according to the National wiring regulation.
5. Be sure to locate the power wiring and the signal wring well to avoid cross-disturbance and their
contact with connecting pipe or stop value body.
6. The wiring attached to this air conditioner is 6m long. Be sure to prolong it with wiring of the same
type and proper length if necessary. Generally, do not twist two wiring together unless the joint is
soldered well and covered with insulator tape.
7. Do not turn on the power until you have checked carefully after wiring.
