lt's strictly prohibited to lay or immerse the electric pump in the water for use,
and the electric motor shall be protected from pouring water and splashing water
and even spraying water of strong flow so as not to damp the electric motor and
damage winding insulation. If installed outdoors, suitable covering should be
provided to prevent exposure to sun and rain, and freezing. If installed indoors, a
drain should be arranged around water pump to form natural drainage to prevent
losses caused by water leakage during the use, maintenance and replacement
of electric pump (especially al such places as basement, kitchen and multi-story
building).
Electric pump should be installed at a place accessible for maintenance and
inspection, and the place should be kept dry and ventilated; when installing
electric pump al a narrow place, electric pump should be installed as shown
in the left figure, and the fan cover should be more than 10cm from the wall to
facilitate heat dissipation.
7. MAINTENANCE
1. The insulation resistance between the winding and enclosure of electric pump shall be inspected regularly,
and the insulation resistance shall not be less than 5MO (megaohm) when approaching the operating
temperature, or else corresponding measures must be taken to reach the requirement before use.
