Note) The specified wire should be used when extending the domestic hot water tank temperature sensor.
In addition, wire tubing should be used to protect wires.
After removing the wire clothing to extend the wire, the connection area should be covered with a heat
shrinkable tube.
Note) For power cable, use an IEC 60245-4 IEC57 or higher, or an H05RN-F wire or higher.
Note) The length of the main power cable refers to the length from the main panel board to the hydro unit,
and should be less than 50 meters in principle.
If the length of the main power cable exceed 50 meters, please contact a Carrier dealer.
Note) The grounding wire should be of at least the same thickness as the power cable.
