2. Install a circuit breaker between power source and the unit.
3. Make sure that wiring screws are fastened. Screw could be loose by vibration during
transportation. (If screws are loose, wires could be burnt-out)
4. Check the Specification of power source
5. Make sure the electrical capacity is sufficient.
6. Starting voltage should be maintained above 90 percent of the rated voltage marked on the
name plate.
7. Make sure the cable thickness matches the power sources specification.
(Please note the relation between cable length and thickness.)
8. Do not install the earth leakage breaker in a place which is wet or moist.
Water or moisture may cause a short circuit.
9. The following troubles could 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 an overload protection device.
- Proper starting power is not given to the compressor.
10. Before supplying power to the indoor unit, please check the wiring of the power and
communication lines.
