1.Pump from the power supply is the power of the motor transmission line should be bold, the pump working voltage range does not exceed the rated voltage of 5% to 12%, otherwise it will make the motor life shortening or burn motor.
2.Water pump should be installed leakage circuit breaker or electric shock protector, and to carry out a reliable grounding, to ensure safety. Measuring the insulation resistance of the motor should be more than 2MQ.
3.When installing on the power switch, the pump air speed minutes, starting, running and check whether it is normal to.
4.After the installation of the pump should be checked whether there is no loosening of the bolt, the tightening torque of the fastening screws is uniform.
