3.6 On-site Wiring
Electrical wiring must be performed by professional
technician according to national regulations.
(1) Correctly mount cable water proof head and
electrical box cover, preventing short circuit
caused by water intruding into electrical box.
(2) Auxiliary electric heating is 3kW. Power line
connection should give concern to live line and
null line, and be grounded strictly. Detailed
wiring diagram refers to wiring diagram and
Fig.3.3.
(3) Temperature sensor is weak electricity signal,
preventing mixed with strong electricity signal.
