CAUTION
Water heater shall have a specialized power
supply, which voltage must in compliance with the rated
voltage.
Power supply circuit of water heater with ground wires that
must reliably connected with the external ground wire, which
shall effective.
Wiring must be performed by professional technicians
according to the circuit diagram.
Set the residual current-operated circuit breaker (RCCB)
according to the relevant electric technical standards of the
State.
Power cable and signal cable shall be laid out orderly and
properly. Distinguish heavy current from weak current.
Without mutual interference, no contact with connective pipes
or valves.
No power cable is attached to this equipment. User could
