1. Check the pump including the cable and the plug before th installation to see whether the-
re is any damage in transit or storage. Check whether insulation resistance exceeds 2M.
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 ca-
binet. 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 ne-
cessary. 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 effecting 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 connec-
tion be avoided. Besides, 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 mo-
tor 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 wetting 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 the prescribed head range except the full head pumps to avoid damage due to over-
load.
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
accidents.
