운반·설치상의 주의사항
USAGE
The suction pipe should be larger than the discharge pipe.
Make the piping run as short as possible and minimize the number of elbows.
The piping should be adequately supported on both sides to reduce mechanical stress on the pump.
* Install a stop valve on the suction side and the discharge side of the pump.
①
Priming the pump: The pump must not be run dry.
1. Make sure the pump has been primed and open the discharge valve.
2. Switch on the power and verify that the motor rotates in right direction. Then turn on the power to pump up water.
3. If water is not primed up, power off and reprime the pump.
4. Make sure that the pump operates without any problem. Then open and close the water tap to verify no leakage.
●
Check the pressure gauge to confirm stable suction and discharge pressure. If the pressure fluctuates,
Reprime the pump.
●
Verify the electronic current flow doesn
’
t exceed the rated value marked on the nameplate.
