1. Check the pump including the cable and the plug before the installation to see whether there
is any damage in transit or storage. Check whether insulation resistance exceeds 2M Ohm.
2. Position the pump properly and connect the end valve (if equipped) with the pump inlet end
using steel or rubber tube. (Do not use soft tube to avoid compression due to suction) for
model WZB and JET and pumps with seld priming prime the start water in the pump cabinet.
Do not fill the inlet pipe too full and there is no need to install the end valve at the lower end
of the inlet pipe, but for the sake of convenience for the second time start it is advisable to
install and end valve. For those pumps with other structure, end valve is necessary. To ensure
reliable use, strainer shall be installed and make sure that the end valve and the strainer are
over 30 cm from the water bottom to prevent impurities from entering the pump and effec-
ting the operation, after the connection between the upper end of inlet pipe and the inlet
end of the pump make sure that one end of the end valve teh strainer of the inlet pipe is in
the water. The inlet pipe shall be as short as possible and multi connection be avoided. Besi-
des, the custion height shall not exceed the suction requirement of the pump.
3. The inlet pipe and its conneciton shall be properly selaed to avoid leakage.
4. The outlet pipe shall be connected securely to prevent water from splashing onto the motor
that may lead to electric leakage.
5. stand shall be used to support the inlet and outlet pipelines which shall not depend solely on
the pump for support.
6. To chnage the pump into automatic control, proper pressure control device shall be fitted at
the outlet hole.
7. It is strictly forbidden to use the pump in water or in submersion and prevent the motor from
being splashed or sprinkled and nor shall it be sprayed with large current water to avoid wet-
ting the motor and causing the damage.
8. The pump shall be equipped with crepp age protector and grounded properly at where the
cable grounding is indicated (expect pumps with three pin plug)
9. For vortex pumps, avoid reaching the maximum head and for centrifugal impeller pumps use
in tehprescribed head range except the full head pumps to avoid damage due to overload.
10. Check the water level to see whether it is lowering and do not let the end valve or lower end
of inlet pipe put of water.
11. In operation, to adjust the pump position or touch the pump, turn off the power to avoid ac-
cidents.
