CAUTION:
(1) During the process of installation and disassembly, please handle the fiber delivery
cable connector gently, and avoid vibration.
(2) Before assembling the laser output head, ensure that the optical lens and cutting head
cavity are clean and free of pollution.

Requirements of Cooling Water:
a) Cooling water needs to be pure water;
b) In order to prevent the water in the water cooler from growing mold and causing pipeline
blockage, it is recommended to add alcohol when filling pure water, and the amount of alcohol
added is 10% of pure water;
c) When the ambient temperature of the equipment is between -10
℃
and 0
℃
, the glycol
solution with a volume ratio of 30% must be used and replaced every two months;
d) If ambient temperature is below -10
℃
, the chiller with both heating and cooling functions must
be used and kept in full-time operation.
Water cooling requirements for output optical cables:
a) Water flow requirements: iHQB fiber delivery cable connector water flow rate greater than
1.5L/min; QD fiber delivery cable connector water flow rate greater than 2.5L/min.
