Electrical Wiring

Important Notes:
1. The air conditioner should use separate power supply with rated voltage.
2. The external power supply to the air conditioner should have grounded wiring, which is linked to the ground
wiring of the indoor and outdoor unit.
3. Qualified persons should do the wiring work according to circuit drawing.
4. Do not turn on the power until a proper check is made after wiring.
5. The integrity of all electrical connections should be verified at least twice during the first year of operation.
6. When replacing any components such as fuses, contactors, cables or relays, use only the exact type, size,
voltage and current rating of the component as furnished from the factory.
7. While removing/fixing supply cord, loosen the top clamp of cord anchorage, route the cord and fix the top clamp
again. Length of the earth conductor should be more than supply conductor for safety in case of cord slippage.
