1, submersible pump installed in the rugged advised the basket and then into the water, the water will also be set up around the pump rugged protective fence. The pump should be upright in the water, the depth of not less than 0.5m, containing a large amount of sediment in the water should not be used.
2, when the submersible pump into the water or from the water, you should cut off the power, pull on the cable or the outlet pipe is strictly prohibited.
3, submersible pumps should be installed to protect access to zero and leakage protection devices within 30m around the water pump at work, can not someone, livestock enter.
4, before start check that:
(1) Water banding firm;
(2) deflated, turn on the water, oiling plug are tightened;
(3) The impeller and the inlet section no debris;
(4) good electrical insulation.
5, after turning on the power, it should first test run, check that the correct direction of rotation, dry running time must not exceed specified in the instructions.
6, should always observe the water level changes, the impeller center to the horizontal distance should be between 0.5 ~ 3.0m, the pump can not fall into or out of the water sludge. Cable must not be wall, the wall with rub.
7, the starting voltage should comply with instructions for use, when the current exceeds the limits specified in the nameplate, should stop to check, and may not frequently switch machines.
8, submersible pumps when not in use, can not long-term immersion in water, should be placed in dry and ventilated room.
