）
2) Requirements on Cooling Water:
Purified water should be used.
In order to prevent the growth of mold that may lead to blockage,
adding alcohol solution to about 10% of the total volume is
recommended.
If ambient temperature is between -10
℃
and 0
℃
, we recommend to
use 30% alcohol(volume ratio), and replace it every 2 months.
If ambient temperature is below -10
℃
, the chiller with both heating
and cooling functions must be used, and keep it in full-time operation.
3) Other cooling system requirements:
Check the entire water system and joints for leaks when starting the
cooling system the first time. The external water pipe must be installed
and connected according to the water inlet (IN) and water outlet (OUT)
indicated according to the laser, otherwise the laser may not work
properly.
If the laser is not used for a long time, the cooling system and the
cooling water inside the laser should be drained, otherwise it will
cause irrecoverable damage to the laser.
Set the water temperature of the cooling system correctly
according to the ambient temperature. If the water
temperature is set too high, the laser will not work properly.
If the water temperature is set too low, condensation will
occur inside the laser or the laser output cable, which will
