c) Cooling water requirements:
1
）
It is recommended to use purified water.
2
）
In order to prevent mould growing that may lead to pipe blockage, we recommend to
add alcohol about 10% of the total volume.
3
）
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.
4
）
If the product is used in an environment that ambient temperature is below -10
℃
,
please to use dual-system chillers (with heating function) and ensure uninterrupted
operation of the cooling system.
