Frequently Asked Questions

1.When no one is using water, the machine will not hibernate and stop. 

First of all, see if the feedback pressure on the right side of the interface reaches the target pressure value on the left.

If it does, first press the stop button to stop the pump manually, then observe if the feedback pressure drops.

If it falls down, check whether the pipeline is leaking, whether the water outlet is not closed, whether the check valve is back to the water, solve the above problems, the pump can naturally hibernate and stop.

2.The pump starts frequently

Firstly, turn up the set pressure

Secondly, adjust the dormant frequency of UO-08 from 30 to 20 Hz.
