Instructions for use
It shall be fully checked whether electric pump is damaged during transportation
and storage prior to installation and use, e.g. whether the cable or outgoing line
and plug (if equipped) are in good condition, and whether insulation resistance is
more than 50 MΩ (mégaohm). or else technical support must be sought to meet
the requirement prior to use.
Prior to the use of electric pump, it is needed to fill the pump body with water
and drain the air before starting the water pump. When pumping well water, if
the water cannot be pumped for 2 to 3 minutes, it is needed to click the "On/Off"
key to stop the pump, and then open the vent cock and add water into the pump
body. Tighten the vent cock and restart the water pump, and repeat the operation
2-3 times until the pump pumps water out.
Electric pump shall be correctly installed with electrical leakage protector,
and reliably earthed at the earthing mark of electric pump or cable, and the
power socket connected shall also be earthed reliably.
Power must be disconnected to avoid accidents before servicing or
touching the water pump while it is working.
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 at such places as basement, kitchen and multi-story
building).
The electric pump can be installed horizontally or vertically.
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 at a narrow place, electric pump should be installed as shown in
the left figure to facilitate heat dissipation.
