(1) Check the pump vent hole, drain hole, oil hole and cable connector seal is loose, if loose must be tightened.
(2) 500 volt shake table to check the insulation resistance should not be less than 0.5 megohm, if below this value, to open the water, venting, drying or drying.
(3) check the cable, if broken or broken, etc., should be replaced to avoid leakage.
(4) Before starting to check all the circuits, switches, to see if the wiring is correct and reliable, and then on the ground idle for 3-5 minutes (time not too long, so as not to damage the parts or burn motor winding), and check the motor Turn the direction is correct, such as the above are no problems, can be placed in water use.
(5) into the water use, must not make the cable force, the use of rope tied to the wellhead on the wooden frame. The maximum depth to be placed in the water is 3 m and the minimum depth is 0.5 m (from the center of the impeller).
(6) operation, should always observe the water level changes in the well, the motor must not be exposed to the water, can not fall into the mud, so as not to affect the motor cooling and burn out the winding. Should be with the well water level changes at any time movements, such as water reduction or interruption, should immediately identify the cause or shutdown inspection. Cable can not friction with the wall, so as not to wear well after the cable along the cable core water infiltrated the motor.
(7) new or re-replaced the whole sealed box fountain pump, use 50 hours later, should check the seal is good, after a monthly inspection, and check the motor rotor and stator between the shielding sleeve seal is good.
(8) after one year of use, should check the pump rust, and rust paint. Such as long-term do not, should be carefully checked and placed in dry and ventilated house custody.
