Water temperature setting
：
Summer (ambient temperature above 30
℃
) 29 ± 0.5
℃
Winter (ambient temperature below 30
℃
) 25 ± 0.5
℃
.
2)
Coolant requirements
：
Pure water is used as cooling water, and it is recommended to use
purified drinking water.
In order to prevent the pipeline blockage caused by mold growth in
the water chiller, it is recommended to add ethanol when filling pure
water, and the volume ratio of ethanol is 10%
When the ambient temperature of the equipment is between - 10
℃
and 0
℃
, ethanol with volume ratio of 30% must be used and replaced
every two months.
。
When the ambient temperature of the equipment is lower than - 10
℃
,
double system (with heating function) chiller must be used, and the
continuous operation of the cooling system shall be ensured.
3)
Other requests of cooling system:
When starting the cooling system for the first time, check whether
there is water leakage in the whole water system and joints. The
external water pipe must be installed and connected according to the
water inlet (in) and water outlet (out) marked by the laser, otherwise
the laser may not work properly.
