2) Coolant requirements:

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 to
add alcohol about 10% of the total volume.

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
℃
, please
to use dual-system chillers ( with heating function ) and ensure uninterrupted operation of the
cooling system.
