Troubleshooting

If the pump doesn't operate, please replug the pump in several 

times until it works normally.

If it still doesn't work, it is probably blocked by particles.

Drain the system and remove the pump housing. Open the pump 

by removing the four housing screws at the bottom.

Remove the housing and pull out the rotor.Clean the rotor with a 

clean cloth and purge all dirt from the pump housing.

Notice
You can connect the PWM+Tach cable to any fan slot on the motherboard. And then the speed of the pump can be controlled by the fan PWM function. If not, 
there will be no PWM and data display function.
The power cable should connect to the power supply to make the pump work.
If you only connect the Power Cable to the power supply, the pump will run at full speed.
