9. START-UP MAINTENANCE
Do not start up the pump before the pump
chamber is filled with water.
Do not touch the electric pump unless its
power has been cut off for at least 5 minutes.
Do not dismount the pump body unless
water in the pump chamber is empted.
9.1 Rotate the fan blade before start-up, check whether the
pump rotation is flexible and then unscrew the water-filling
plug, fill the pump chamber with clean water from the water
injection hole, then tighten the plug screw after gas has been
completely discharged.
The valve should be shut tightly while starting up the pump.
After the pump discharges water and operates normally, adjust
the valve to the required flow (flow and lift will be displayed on
the nameplate).
ATTENTION:
1) In case no water is discharged after being started for more
than 5 minutes with water filled, turn off the electric pump,
re-fill water or check whether the inlet pipeline has leakages.
2) In case of any frost and ice damages, please open the drain
plug to empty water in the pump chamber. When start up the
pump again, open the drain plug, fill water and tighten it and
then the pump is usable.
3) In case not use for a long time, water in the pump should
be emptied. The pump body, impeller and support should be
cleaned and coated with anticorrosive oil before they are put in
a ventilated and dry place for use.
4) In case the pump is halted for a long time, start it up again
according to above diagram.
5) In summer or when the ambient temperature is high, pay
attention to ventilation, avoid dew on electrical parts which will
result in electrical faults.
6) In case the motor is hot or abnormal, cut off the power
immediately and check faults according to the following table.
