Care and maintenance Power supply and wiring requirement 1. Power frequency of air-conditioner should be 60Hz, voltage: AC 230V±10% If voltage are over may cause the parts of electric equipment damaged. If the voltage are too low may cause shake on compressor, it may let the cooling system damaged, and also, the compressor and parts will not work. Voltage should be stable, which cannot have a big fluctuation. 2. User power supply should be provided a reliable earthing connect. (see earth requirement) 3.
Care and maintenance Caution 1. Please check the earth connection before running test. 2. Voltage should be following the requirement. The voltage should not be too big after the running test (normally, 9000BTU unit not over 15V, 18000BTU unit not over 10V, 28000BTU unit not over 5V. 3.
