Water temperature setting:
Summer (ambient temperature higher than 30
℃
): 29

℃
;
Winter (ambient temperature lower than 30
℃
): 25
±

.
Purified water should be used. In order to prevent mildew growing, we recommend to add
alcohol about 10% of total volume. The cooling system should equip with filter. Check and clean
the filter every six months.
If the product is used in an environment that ambient temperature is between -10
℃
and
0
℃
, we recommend to use 30% alcohol, and replace it every two months.
If the product is used in an environment that ambient temperature is below -10
℃
, you must
use chiller with both heating and cooling functions, and keep it in full-time operation.
When connecting to the laser for the first time, ensure that the flow and return connections
are correct.
If you will not use the laser for a long time, water should be emptied from the laser, and
then block inlet and outlet. Failure to do so may lead to permanent equipment damage.
CAUTION:
Please set the water temperature in strict accordance with the
requirements above. Too low temperature may lead to condensation in the
Laser module and the output head. This can cause serious damage to the
equipment.
