UNICH LJX-9060 Chinese Laser Engraver Problem

[Rockshaft]

Hi everybody,

I recently bought a chinese laser engraver from UNICH and as soon as I start the water chiller the alarm goes on imediately.
Everything is connected correctly and the chiller is filled at recomended level.
I was wondering if someone went through the same problem ?

Thanks.

Are you sure?
① Take out one of the water pipes and connect to the water chiller where marked as “OUTLET”, the other side of the pipe connect to the machine where marked as “Water IN”.
② The other pipe, please connect to “INLET” of water chiller and “Water OUT” of machine.
