Coolant requirements
：
1
）
The cooling water is pure water. It is recommended to use pure drinking water
；
In
order to prevent mould growing that may lead to pipe blockage, we recommend toadd
alcohol about 10% of the total volume.
2
）
When the ambient temperature ranging between -10
℃
and 0
℃
, user need to add
alcohol about 30% of the total volume, change alcohol every two years.
3
）
When the ambient temperature below -10
℃
, user must use dual-cooling water chiller,
and ensure continuity of work.

Other requirements for chiller
：
1
）
When starting the cooling system for the first time, check the entire water system and
the joint for water leakage. The external water pipe must be installed and connected
according tothe inlet (IN) and outlet (OUT) by the laser. Otherwise, the laser may not
work properly.
2
）
If you will not use the laser for a long time, water must be emptied from the product,
and then both the inlet and outlet must be blocked with the nuts we provide. Failure to
do so maylead to permanent equipment damage.
3
）
When the customer is empting the cooling water of the laser water-cooling system,
please use compressed gas with pressure less than 0.5MPa, otherwise it will cause
irreparable damage to the chiller.
Please set the water temperature in strictly accordance with the requirements
above. Too low temperature may lead to condensation on the laser module and
the output cable. This can cause serious damage to the equipment.
Make sure that the water temperature reaches the set point and the cooling
system is working well before you start the laser.(summer: 25
