(2) If the unit is equipped with a grounding cable, connect one end of the
ground cable to the grounding screw of the water tank, and the other
end to the grounding screw in the connection box on the right panel of
the main unit.
(3) Select an appropriate power cable (with a leakage circuit breaker)
according to the power configuration table, and connect it to the main
power supply.
(4) Connect the interface of the temperature sensor delivered with the water
tank to the interface coming from the connection box of the main unit
according to the identifiers (“TOP” for “TOP” and “BOTTOM” for
“BOTTOM”) on the line of the temperature sensor. Put the temperature
sensor inside the connection box. The line of the temperature sensor
must be clamped tightly. Check whether the temperature sensor is
securely fastened. The interface marked "CYCLE" coming from the
main unit interconnects with the cycle temperature sensor only during
installation of a water return system.
(5) Use wire clips to clamp the strong wires, and install the connection box
to the original place.
(6) Fasten the wired controller, and connect it to with the communications
line coming from the main unit.
(7) The communications line of the wired controller and the line of the
temperature sensor should be separated from the power cable, and the
distance between them should be greater than 20 cm. Otherwise, the
unit may not be able to communicate properly. Strong wires and weak
wires need to be separately sheathed.
