CAUTION
The primary power supply capacity is for the air conditioner itself, and does not include the
•
concurrent use of other devices.
Do not start operation until the refrigerant is charged completely. The compressor will fail if it is
•
operated before the refrigerant piping charging is complete.
Transmission cable between indoor unit and outdoor unit is 230 V.
•
Be sure not to remove thermistor sensor etc. from power wiring and connection wiring.
•
Compressor may fail if operated while removed.
Start wiring work after closing branch switch and over current breaker.
•
Use an earth leakage breaker that is capable of handling high frequencies. Because the outdoor
•
unit is inverter controlled, a high-frequency earth leakage breaker is necessary to prevent a
malfunction of the breaker itself.
When using an earth leakage breaker that has been designed solely for ground fault protection,
•
be sure to install a fuse-equipped switch or circuit breaker.
Do not connect the AC power supply to the transmission line terminal board. Improper wiring
•
can damage the entire system.
Do not use crossover power supply wiring for the outdoor unit.
•
If the temperature surrounding the breaker is too high, the amperage at which the breaker cuts
•
out may decrease.
