1. Electric circuit's connection
2. The electric circuit installment should strictly according to the
conventional electrician standard operation
a The power line is three, respectively is L, N and the grounding, uses
1.5mm2 the power line, according to chart connection
b Examination: After the electric circuit meets, before the circular
telegram use, the examination leakage protects the plug “L” and “N” the
resistance should during 30~40 ohms, “L” and the place, “N” and
resistance between the place should above 2,000,000,000,000 ohms
The water quality of most public supplies is suitable for the water heating
