What are the precautions when using the aerator?

(1) The aerator uses 380V three-phase alternating current, and the power supply must use a special circuit. The power connection must be carried out by a professional electrician in accordance with the safety operation procedures for electricity use.

(2) The motor must be equipped with leakage, phase failure and undervoltage protection devices to ensure the normal operation of the circuit.

(3) The power cord should be a three-phase four-wire copper-core rubber cable, the recommended wire diameter is 4x2.5mm2, the wiring should be firm and the grounding should be reliable.

(4) The input power supply voltage is 380V, and the voltage fluctuation value does not exceed 5% of the rated voltage, so as to prevent undervoltage from damaging the motor after long-term use.

(5) It is forbidden to connect the fixed aerator with metal wires such as iron wire.

(6) When maintaining, maintaining and transporting the aerator or disassembling the motor, the power supply must be cut off first to ensure personal safety.

(7) When the aerator is turned on, no one is allowed to go down to the fish pond to prevent electric shock and mechanical accidents.
