12.8 Inspection before operation
1. Voltage is consistent with requirement; phase voltage and phase current are balaced.
2. Inspecting the power source connection, especially section of the power cord, earthing and
connecting terminal.
3. Water pipe must keep clean without impurities. At last, flush the pipe 2 or 3 times (bypassing the
