The minimal voltage must be over 85% of the rated voltage. The voltage should
be 10%
of the rated voltage for unit running. The voltage difference should
be within
±
2% among different phases.
Check if the power supply complies with the requirement. The phase protection is
provided. Check if the phase is correct before starting the unit. If the green light is on, it
indicates the power supply is connected correctly. If the yellow light is on, it indicates
missing phase. If red light is on, it means wrong phase.

Unit Wiring
Must take the voltage drop and electric current into consideration while wiring.
Comply with electric regulations and decide the wiring and switch capacity to ensure the
normal operation.
Suggest to use the following chart to select the wires
(RV or BVR):
The data in the following chart is the minimal requirement:

Note:
1.Connect the power supply wire to main connector in the control box and the unit must
be grounding.
2.Connect the wire from the control panel to main control board.
3.The unit must be well earthen.
4.If the electric heater is equipped, please connect its wire connection terminal to the
power supply.
5.If use FCU, please refer to the electric diagram and control manual
6.Connect the flow switch to the connector in the circuit board
。
Warning
Don’t put power on before wires are well connected to avoid any accidents.
Use copper wires for wire terminal connection to avoid rust and over heating.
