●
The power supply cable shall be connected to the power supply terminal and shall be fixed with
clamp as in the following figure.
●
The unbalance of power shall be within 2% of power supply rating.
- If the power supply unbalance is great, the lifetime of condenser is shortened.
- If the power supply unbalance exceeds 4%, the indoor unit stops and error mode displays.
