1.When lifting the device, absolute prohibition of lifting cable directly or use cable to lift other heavy objects.
2.The cable ends is strictly prohibited immersed in the liquid.
3.The housing of all equipment should be grounded to prevent electric shock.
4.The inner diameter of the outlet pipe should be consistent with the requirements (in principle, be smaller than the pump outlet diameter).
5.Submersible sewage pump can not be placed at the entrance. When the water pump on the floating sand or mud, due to vibration, the pump resulting in subsidence, in this case, we recommend that the pump is placed on a large plate.
6.Pumps used in the sewage, the case will accumulate around the mud, debris, etc., resulting in reduced heat transfer rate, rise in temperature inside the motor and shorten the life of the stator or cause undue tripping, so sewage pumping level after withdrawing to a minimum, clear debris (once a year) and, if necessary, open the cooling jacket fixed plate, clean-up and circulating water cooling jacket in the debris.
7.When the temperature drops below 0 ℃, if the pump is still functioning can continue to use, or should be lifted dry and ventilated place, and pay attention to antifreeze.
